[0001] [0001] The present invention in general relates, for example, to device usability in multi-core or multi-chip embedded solutions.BACKGROUND OF INVENTION
[0002] [0002] Embedded devices generally comprise objects that contain an embedded computing system, which may be enclosed by the object. The embedded computer system may be designed with a specific use in mind, or the embedded computer system may be at least in part general-purpose in the sense that a user may be enabled to install software in it. An embedded computer system may be based on a microcontroller or microprocessor CPU, for example.
[0003] [0003] Embedded devices may comprise one or more processors, user interfaces and displays, such that a user may interact with the device using the user interface. The user interface may comprise buttons, for example. An embedded device may comprise a connectivity function configured to communicate with a communications network, such as, for example, a wireless communications network. The embedded device may be enabled to receive from such a communications network information relating to, for example, a current time and current time zone.
[0004] [0004] More complex embedded devices, such as cellular telephones, may allow a user to install applications into a memory, such as, for example, a solid-state memory, comprised in the device. Embedded devices are frequently resource-constrained when N compared to desktop or laptop computers. For example, memory capacity may be more N limited than in desktop or laptop computers, processor computational capacity may be 3 lower and energy may be available from a battery. The battery, which may be small, may z 25 — be rechargeable. a N [0005] Conserving battery power is a key task in designing embedded devices. A O lower current usage enables longer time intervals in-between battery charging. For O example, smartphones benefit greatly when they can survive an entire day before needing recharging, since users are thereby enabled to recharge their phones overnight, and enjoy — uninterrupted use during the day.
[0006] [0006] Battery resources may be conserved by throttling a processor clock frequency between a maximum clock frequency and a lower clock frequency, for example one half of the maximum clock frequency. Another way to conserve battery power is to cause a display of an embedded device to switch itself off then the device is not used, since displaying content on a display consumes energy in order to cause the display to emit light that humans can see.SUMMARY OF THE INVENTION
[0007] [0007] The invention is defined by the features of the independent claims. Some specific embodiments are defined in the dependent claims.
[0008] [0008] According to a first aspect of the present invention, there is provided an apparatus, such as a personal device, comprising at least one processor with at least one processing core, at least one display, at least one sensor, at least one memory including a computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to: — determine the location of the apparatus by means of a sensor providing location information to said at least one processing core; — transmit from said apparatus a query to a thematic map database server, the query comprising an indication of the current location of the apparatus; — update said apparatus with thematic maps related to said location from said server by downloading thematic map data and storing the thematic map data in said at least one memory of said apparatus; — present to a user of said apparatus on a display in a first display mode on said N at least one display at least one downloaded thematic map as one of a suggested activity; N — selecting an activity session based on at least one of the following criteria: 3 25 — user selection input, a pre-recorded user preference, user activity history, intensity of > activities in said location, special activities in said location, time of the day, time of the E year, the location of said activity or a second location adjacent to said present location, and > performing in a seguence: S a) initiating a selected activity and displaying to the user by a first processing N 30 core in said first display mode performance-related information relating to physical performance of said user in said activity;
[0009] [0009] In a second aspect of the invention, a method is provided for presenting information to a user of an apparatus, such as a personal device, said device comprising at least one processor having at least on processing core, at least one display, at least one sensor and at least one memory including computer program code, said method comprising — the steps of: — determining the location of the apparatus by means of a sensor providing location information to said at least one processing core; — transmitting from said apparatus a query to a thematic map database server, the query comprising an indication of the current location of the apparatus; — updating said apparatus with thematic maps related to said location from said server by downloading thematic map data and storing the thematic map data in said at least one memory of said apparatus; — presenting to the user in a first display mode on said at least one display at o least one downloaded thematic map as one of a suggested activity; < 25 - selecting an activity session based on at least one of the following criteria: N user selection input, a pre-recorded user preference, user activity history, intensity of > activities in said location, special activities in said location, time of the day, time of the E year, the location of said activity or a second location adjacent to said present location, and N performing in a seguence: O 30 a) initiating a selected activity and displaying to the user in said first display O mode performance-related information relating to physical performance of said user in said activity;
[0010] [0010] In some embodiments, at least two processing cores are provided, wherein a selected activity is initiated by a first processing core in said first activity display mode, said first power-save mode is entered by putting said first processing core in a hibernating mode and by switching to said second display mode using a second processing core, and — said second power-save mode is entered by putting said second processing core in a hibernating mode.
[0011] [0011] In some embodiments, the clock unit is a Real Time Clock (RTC) unit which updates said display in said second power-save mode in predefined time intervals with — reduced thematic maps stored in said at least one memory of the apparatus, wherein said reduced thematic map to be shown is selected based on the current time as registered by said RTC unit 5 [0012] Various embodiments of the first aspect may comprise at least one feature O 25 — from the following bulleted list:
[0013] [0013] A thematic map database, for example a heat map, may be compiled to cover a geographic area. Users may engage in activity sessions while in the geographic area. Activity types of such activity sessions may include jogging, swimming and cycling, for example. When a user wishes to engage in an activity session of his own, his device may determine a route for this activity session based at least in part on the thematic map database. Determining the route may comprise designing the route, optionally based partly — on user settings, based on where other users have engaged in activity sessions of the same o type in the past. For example, a jogging route may be determined based, at least partly, on N indications where other users have jogged in the past. Route determination may be partly = based on further considerations as well, as will be laid out below. + I [0014] FIGURE 1A illustrates a system in accordance with at least some a = 25 embodiments of the present invention. The system comprises device 110, which may
[0015] [0015] Device 110 may be communicatively coupled with a communications network. For example, in FIGURE 1A device 110 is coupled, via wireless link 112, with base station 120. Base station 120 may comprise a cellular or non-cellular base station, wherein a non-cellular base station may be referred to as an access point. Examples of — cellular technologies include wideband code division multiple access, WCDMA, and long term evolution, LTE, while examples of non-cellular technologies include wireless local area network, WLAN, and worldwide interoperability for microwave access, WiMAX. Base station 120 may be coupled with network node 130 via connection 123. Connection 123 may be a wire-line connection, for example. Network node 130 may comprise, for — example, a controller or gateway device. Network node 130 may interface, via connection 134, with network 140, which may comprise, for example, the Internet or a corporate network. Network 140 may be coupled with further networks via connection 141. In some embodiments, device 110 is not configured to couple with base station 120.
[0016] [0016] Device 110 may be configured to receive, from satellite constellation 150, satellite positioning information via satellite link 151. The satellite constellation may comprise, for example the global positioning system, GPS, or the Galileo constellation. Satellite constellation 150 may comprise more than one satellite, although only one satellite is illustrated in FIGURE 1A for the same of clarity. Likewise, receiving the positioning information over satellite link 151 may comprise receiving data from more — than one satellite.
[0017] [0017] Alternatively, or additionally to receiving data from a satellite constellation, device 110 may obtain positioning information by interacting with a network in which base station 120 is comprised. For example, cellular networks may employ various ways to S position a device, such as trilateration, multilateration or positioning based on an identity N 25 — of a base station with which attachment is possible or ongoing. Like-wise a non-cellular + base station, or access point, may know its own location and provide it to device 110, I enabling device 110 to position itself within communication range of this access point. a N [0018] Device 110 may be configured to obtain a current time from satellite O constellation 150, base station 120 or by reguesting it from a user, for example. Once O 30 device 110 has the current time and an estimate of its location, device 110 may consult a look-up table, for example, to determine a time remaining until sunset or sunrise, for example. Device 110 may likewise gain knowledge of the time of year.
[0019] [0019] Network 140 may be coupled to a database server 160 via a connection 161, or the further network connection 141. When device 110 apparatus has determined the present location of itself it may transmit a guery to database server 160 acting as a thematic map database server. The guery may comprise an indication of the current location of the apparatus obtained by, for example, a global positioning system as explained above. Updated thematic map data related to the present location of the device 110 may then be downloaded from the server 160 over network connections 161 or 141 and stored in a memory of the device 110.
[0020] [0020] The device may be configured to present to the user a selection of updated thematic maps as heatmaps created for different sports activities in said location. The updated heatmaps thus stored in the memory of the device 110 may be used offline in activity sessions.
[0021] [0021] Device 110 may be configured to provide an activity session. An activity — session may be associated with an activity type. Examples of activity types include rowing, paddling, cycling, jogging, walking, hunting and paragliding. In a simplest form, an activity session may comprise device 110 displaying a map of the surroundings, and a route on the map that relates to the activity session. Device 110 may be configured to display, on the route, an indication where along the route the user is currently located, enabling the user to see the place along the route where his jog, for example, is at the moment progressing.
[0022] [0022] According to some embodiments, the device 110 may be configured to present to the user a selection of updated thematic maps as heatmaps created for different S sports activities in second locations outside but adjacent to said present location. Some N 25 — activities preferred by the user, such as cycling for example, may involve moving long + distances and/or for a lengthy time. In the planning of such activities it may be beneficial z to have heatmaps also covering locations nearby the present one. a
[0024] [0024] According to some embodiments, the device 110 may first be able to determine the present location of the device, to transmit a query to a thematic map database server, the query comprising an indication of the current location of the device, and then to update itself with thematic maps related to its location by downloading thematic map data from the server and store the thematic map data in the memory of the device 110. Then, the device may present to the user on the display in a first display mode a selection of downloaded thematic maps as suggested activity types. The selection may be based on at least one of the criteria of a pre-recorded user preference, user activity history, intensity of activities in said location, special activities in said location, time of the day, time of the — year, or a second location adjacent to said present location. In response to a user selection input, the device 110 may then initiate an activity session of one of the activity being selected, and display a thematic map of the activity in a second display mode.
[0025] [0025] Processing heatmaps, sensor information, displays and other hardware required for tracking the whereabouts and physical performance of a person is a power- consuming task. From a battery performance point of view, it is important to minimize the energy consumption of the device 110. Therefore, a first display mode has been envisaged, where all relevant data and features required for the user to perform searching, browsing and a selection of activities, as well as using any other features offered by the device. This requires much battery power, but once the activity selection is made and initiated, the device 110 may enter a low-power mode focusing only on processing data which is essential for the activity in question. Such a low-power mode may involve the use of a second display mode, where for example, resolution is reduced, colours are not displayed, 5 map display is simplified and/or sensors are shut off and their corresponding information is O 25 — suppressed on the display.
[0027] [0027] In some embodiments, updated thematic heatmaps may be created for different sports activities also in second locations outside, but adjacent to the present location. This may be beneficial if the activity, such as cycling, takes place over considerable distances. The device 110 may be configured to automatically update thematic maps related to its location from a thematic map database server anytime when the apparatus is being charged and is connected to a wireless network with coverage of its present location.
[0028] [0028] In some embodiments, the updated thematic maps are stored in a memory of the device 110 for offline use. Thus a stored thematic map of an activity session that is to be initiated may be displayed directly in a second display mode.
[0029] [0029] An activity session in device 110 may enhance a utility a user can obtain — from the activity, for example, where the activity involves movement outdoors, the activity session may provide a recording of the activity session. An activity session in device 110 may, in some embodiments, provide the user with contextual information during the activity session. Such contextual information may comprise, for example, locally relevant 5 weather information, received via base station 120, for example. Such contextual O 25 information may comprise at least one of the following: a rain warning, a temperature N warning, an indication of time remaining before sunset, an indication of a nearby service + that is relevant to the activity, a security warning, an indication of nearby users and an z indication of a nearby location where several other users have taken photographs. Where a the contextual information comprises a security warning, the warning may comprise a A 30 — security route, determined in a way that enables the user to avoid danger. For example, in N case of a chemical leak, the security route may comprise a route that leads indoors or to N public transport. The device 110 may determine a security route, or the device 110 may receive the security route, at least in part, from a network. The security route may be determined using existing roads, pathways and other transit routes that are known to the entity determining the security route. Transit routes may be known from a public mapping service, for example.
[0030] [0030] A recording may comprise information on at least one of the following: a route taken during the activity session, a metabolic rate or metabolic effect of the activity session, a time the activity session lasted, a quantity of energy consumed during the activity session, a sound recording obtained during the activity session and an elevation map along the length of the route taken during the activity session. A route may be determined based on positioning information, for example. Metabolic effect and consumed energy may be determined, at least partly, based on information concerning the user that — device 110 has access to. A recording may be stored in device 110, an auxiliary device, or in a server or data cloud storage service. A recording stored in a server or cloud may be encrypted prior to transmission to the server or cloud, to protect privacy of the user.
[0031] [0031] An activity session may have access to a backhaul communications link to provide indications relating to the ongoing activity. For example, search and rescue — services may be given access to information on joggers in a certain area of a forest, to enable their rescue if a chemical leak, for example, makes the forest unsafe for humans. In some embodiments, routes relating to activity sessions are provided to a cloud service for storage when the activity sessions start, to enable searching for missing persons along the route the persons were planning to take. — [0032] The user may initiate an activity session by interacting with a user interface of device 110, for example. Where device 110 has s small form factor, the user interface may be implemented over a limited user interaction capability, such as, for example, a ES small screen, small touchscreen, and/or limited number of push buttons. A limited user N interaction capability may make it arduous for the user to perform complicated interactions = 25 — with device 110, which makes it less likely the user will choose to interact with device 110. = Therefore, it is of interest to simplify the interaction between device 110 and the user, to z make it easier for the user to complete the interaction, and thus more likely the user will N perform the interaction.
[0034] [0034] In general, a thematic map database 160 may associate at least one form of data with a geographic location. For example, the thematic map database may associate past indications of activity sessions with geographic locations, for example to enable mapping areas where activity sessions of a given activity type have been performed. Areas may be mapped as to the intensity, or frequency, of past indications of activity session and type. Thus a first area of a lake may be associated with frequent rowing, and another area of the same lake with less frequent, but still non-zero, rowing. Such a frequency may be referred to as intensity, and the thematic map database may, in general, associate activity type intensities with locations. Alternatively, the thematic map database may simply associate to whether an activity session of a given activity type has in the past been performed in a geographic location. Alternatively, the thematic map database may indicate any specialities of activities in the location. Additionally, or alternatively, a traffic density — may be associated with the geographic locations. Traffic density may comprise pedestrian or vehicular traffic density, for example. Walking or jogging may be less pleasant, or less healthy, in areas with a high vehicular traffic density due to exhaust fumes, wherefore a route relating to an activity session with such type may be determined in a way that avoids such high-traffic density areas. Likewise, additionally or alternatively, crime density may — be mapped, and employed in route determination to avoid high-crime areas. Avalanche risk density, obtained from meteorological services, may similarly be used to route ski activity sessions in safe areas. In some embodiments, places where many users have taken photographs may be used in routing, such that routes are determined to visit frequently S photographed locations, since such locations are likely to be beautiful and inspiring.O
[0036] [0036] A route may be determined to be able to be interrupted. For example, where the activity comprises cycling, the route may come close to the starting and ending location close to a midpoint of the route, to enable the user to cut the route short. The user may specify in user settings he wishes to engage in an interruptable route, or interruptability may be a default setting that is attempted to comply with, where possible.
[0037] [0037] The level of physical exertion, in terms of energy consumption, oxygen consumption, cardiovascular effect, EPOC or recovery time length, which the route causes — in the user, may be modified by determining elevation changes along the route. Where the user wishes a light activity session, the route may be determined as relatively flat, and where the user wishes for a strenuous activity session, the route may be determined in a way that it has more elevation changes. Using the thematic map database in connection with elevation data in this sense may comprise, for example, determining the route based — on elevation changes to match the desired strenuousness, in an area which the thematic map database indicates that activity sessions of a corresponding type have been conducted in the past. In general, the user settings may be employed in determining the route after a suitable area for the route has been identifier using the thematic map database.
[0038] [0038] A time of year and/or a time of day may be employed in either the thematic — map database or in the determining of the route. For example, the thematic map database 160 may comprise data collected at different times of year, for example a same location may be associated with frequent jogging in summertime and frequent skiing during the winter months. Thus, the database may return a jogging route in the location in case the N guery is made in the summer, and the database may return a skiing route in the location in = 25 — case the query is made in the winter. Alternatively, or in addition, device 110 may select = activity types consistent with the time of year, or time of day, from the set of activity types E returned from the database when determining the predicted user activity type. Device 110 N may perform this task in embodiments where a thematic map database doesn't collect 3 statistics separately according to time of year or day, for example. As a specific example, S 30 local residents may consider a certain location as safe during the day but unsafe after dark. In such a situation, a user reguesting a jogging route could be routed to this location if the reguest is made in the daytime, but routed elsewhere if the reguest is made after dark.
[0039] [0039] In general, the thematic map database 160 may be comprised in a server or cloud device, or it may be downloaded, at least in part, to device 110 or an auxiliary device, for offline use. An auxiliary device is described below in connection with FIGURE 1B. While described herein primarily as a route determination method performed by device 110, in various embodiments of the invention the route determination may take place in another device, such as the auxiliary device or a cloud computing device, for example. The user may have an account in a cloud computing service, where his information may be stored and he may request for a route to be determined and furnished to his device, such as, for example, device 110.
[0041] [0041] More than one route may be determined, such that at least one of the determined routes is presented to the user as a suggested route. For example, two routes may be determined that match reguirements defined by the user, and these two routes may — then be presented as suggested routes, with information concerning each route presented to the user as well. For example, energy consumption, estimated time to completion and/or length of a route may be presented to assist the user in making a selection. Energy consumption, estimated time to completion and/or other suitable information may be determined, at least partly, on the elevation information. — [0042] Information may be presented also, or alternatively, concerning segments of any suggested route, to enable the user to construct his route from interconnected segments. N [0043] In some embodiments, the user needn't explicitly select a suggested route, 2 rather, the device may deduce from the way positioning information changes, which route I 25 — theuser is following. As a response, any other suggested routes may be removed from the = display to reduce clutter. In case the user deviates from the route, the device may notice * this from the positioning information, and responsively determine an alternative route for 3 the user, which may again be displayed. Thus movement of the user may cause, via the N positioning information, an approval of a suggested route and/or a new determination of a N 30 new suggested route in case of deviation from a previously approved route. Such a new suggested route may be determined from the current location of the device to the same end point as the originally approved route. Such an end point may comprise the start point of the route, or, alternatively, another point input by the user. Remaining time, energy consumption and/or other information may be presented concerning the new suggested route.
[0044] [0044] FIGURE 1B illustrates a system in accordance with at least some embodiments of the present invention. Like numbering denotes like structure as in FIGURE 1A. FIGURE 1B embodiments comprise an auxiliary device 110x.
[0045] [0045] Device 110 may be communicatively coupled, for example communicatively paired, with an auxiliary device 110x. The communicative coupling, or pairing, is illustrated in FIGURE 1A as interface 111, which may be wireless, as illustrated, or wire- — line, depending on the embodiment. Auxiliary device 110x may comprise a smartphone, tablet computer or other computing device, for example. Auxiliary device 110x may comprise a device that the owner of device 110 uses to consume media, communicate or interact with applications. Auxiliary device 110x may be furnished with a larger display screen than device 110, which may make auxiliary device 110x preferable to the user when a complex interaction with an application is needed, as a larger screen enables a more detailed rendering of interaction options. In some embodiments, such as those illustrated in FIGURE 1A, auxiliary device 110x is absent.
[0046] [0046] In some embodiments, where an auxiliary device 100x is present, device 110 is configured to use connectivity capability of auxiliary device 110x. For example, device 110 may access a network via auxiliary device 110x. In these embodiments, device 110 need not be furnished with connectivity toward base station 120, for example, since device 110 may access network resources via interface 111 and a connection auxiliary device 110x has with base station 120. Such a connection is illustrated in FIGURE 1B as N connection 112x. For example, device 110 may comprise a smart watch and auxiliary 2 25 — device 110x may comprise a smartphone, which may have connectivity to cellular and/or = non-cellular data networks. Likewise, in some embodiments device 110 may receive z satellite positioning information, or positioning information derived therefrom, via N auxiliary device 110x where device 110 lacks a satellite positioning receiver of its own. A O satellite connection of auxiliary device 151x is illustrated in FIGURE 1B as connection O 30 151X.
[0047] [0047] In some embodiments, device 110 may have some connectivity and be configured to use both that and connectivity provided by auxiliary device 110x. For example, device 110 may comprise a satellite receiver enabling device 110 to obtain satellite positioning information directly from satellite constellation 150. Device 110 may then obtain network connectivity to base station 120 via auxiliary device 110x. For example, device 110 may transmit a query to the thematic map database via auxiliary device 110x. In some embodiments, device 110 is configured to request, and responsively to receive, sensor information from auxiliary device 110x. Such sensor information may comprise acceleration sensor information, for example. In general, processing, such as route determination and/or communication processing, may be distributed in a suitable way between device 110, auxiliary device 110x and/or a cloud computing service.
[0048] [0048] Similarly, as discussed in connection with FIGURE 1A, network 140 may be coupled to a thematic map database server 160 via an auxiliary device 110x and a connection 161, for example. Updated thematic map data related to the present location of the device 110 may be downloaded from the server 160 and stored in a memory of the device 110, or in a memory of the auxiliary device 110x. The device 110 may be — configured to automatically update thematic maps from the server 160 when the apparatus is being charged with a charging device 170 and is connected to a wireless network 112, either directly or via the auxiliary device 110x.
[0049] [0049] Furnishing an embedded device with two or more processor cores, at least some of which are enabled to control the display of the device, makes possible power savings where a less-capable processor core is configured to toggle a more capable processor core to and from a hibernation state. A hibernation state may comprise that a clock freguency of the more capable processing core is set to zero, for example. In a o hibernation state, in addition to, or alternatively to, setting the clock freguency of the more O capable processing core to zero, a memory refresh rate of memory used by the more N 25 — capable core may be set to zero. Alternatively to zero, a low non-zero frequency may be + used for the clock frequency and/or the memory refresh frequency. In some embodiments, I a more capable processing core may employ a higher-density memory technology, such as a double data rate, DDR, memory, and a less capable processing core may employ a lower- A density memory technology, such as static random access memory, SRAM, memory. In a N 30 — hibernation state the hibernated processing core, or more generally processing unit, may be N powered off. Alternatively to a processor core, an entire processor may, in some embodiments, be transitioned to a hibernation state. An advantage of hibernating an entire processor is that circuitry in the processor outside the core is also hibernated, further reducing current consumption.
[0050] [0050] Device 110 may comprise two or more processing units. The two or more processing units may each comprise a processing core. Each processing unit may comprise one or multiple uniformal or heterogeneous processor cores and/or different volatile and non-volatile memories. For example, device 110 may comprise a microprocessor with at least one processing core, and a microcontroller with at least one processing core. The processing cores needn’t be of the same type, for example, a processing core in a microcontroller may have more limited processing capability and/or a less capable memory — technology than a processing core comprised in a microprocessor. In some embodiments, a single integrated circuit comprises two processing cores, a first one of which has lesser processing capability and consumes less power, and a second one of which has greater processing capability and consumes more power. In general a first one of the two processing units may have lesser processing capability and consume less power, and a second one of the two processing units may have greater processing capability and consume more power. Each of the processing units may be enabled to control the display of device 110. The more capable processing unit may be configured to provide a richer visual experience via the display. The less capable processing unit may be configured to provide a reduced visual experience via the display. An example of a reduced visual — experience is a reduced colour display mode, as opposed to a rich colour display mode. An another example of a reduced visual experience is one which is black-and-white. An example of a richer visual experience is one which uses colours. Colours may be represented with 16 bits or 24 bits, for example. S [0051] Each of the two processing units may comprise a display interface configured N 25 — to communicate toward the display. For example, where the processing units comprise a + microprocessor and a microcontroller, the microprocessor may comprise transceiver z circuitry coupled to at least one metallic pin under the microprocessor, the at least one a metallic pin being electrically coupled to an input interface of a display control device. The A display control device, which may be comprised in the display, is configured to cause the N 30 — display to display information in dependence of electrical signals received in the display N control device. Likewise the microcontroller in this example may comprise transceiver circuitry coupled to at least one metallic pin under the microcontroller, the at least one metallic pin being electrically coupled to an input interface of a display control device. The display control device may comprise two input interfaces, one coupled to each of the two processing units, or alternatively the display control device may comprise a single input interface into which both processing units are enabled to provide inputs via their respective display interfaces. Thus a display interface in a processing unit may comprise transceiver circuitry enabling the processing unit to transmit electrical signals toward the display.
[0052] [0052] One of the processing units, for example the less capable or the more capable one, may be configured to control, at least in part, the other processing unit. For example, the less capable processing unit, for example a less capable processing core, may be enabled to cause the more capable processing unit, for example a more capable processing — core, to transition into and from a hibernating state. These transitions may be caused to occur by signalling via an inter-processing unit interface, such as for example an inter-core interface.
[0053] [0053] When transitioning into a hibernating state from an active state, the transitioning processing unit may store its context, at least in part, into a memory, such as for example a pseudostatic random access memory, PSRAM, SRAM, FLASH or ferroelectric RAM, FRAM. The context may comprise, for example, content of registers and/or addressing. When transitioning from a hibernated state using a context stored in memory, a processing unit may resume processing faster and/or from a position where the processing unit was when it was hibernated. This way, a delay experienced by a user may — be minimised. Alternative terms occasionally used for context include state and image. In a hibernating state, a clock freguency of the processing unit and/or an associated memory may be set to zero, meaning the processing unit is powered off and does not consume energy. Circuitry configured to provide an operating voltage to at least one processing unit S may comprise a power management integrated circuit, PMIC, for example. Since device N 25 110 comprises another processing unit, the hibernated processing unit may be powered + completely off while maintaining usability of device 110. E [0054] When transitioning from a hibernated state to an active state, the transitioning N processing unit may have its clock freguency set to a non-zero value. The transitioning 3 processing unit may read a context from a memory, wherein the context may comprise a S 30 — previously stored context, for example a context stored in connection with transitioning into the hibernated state, or the context may comprise a default state or context of the processing unit stored into the memory in the factory. The memory may comprise pseudostatic random access memory, SRAM, FLASH and/or FRAM, for example. The memory used by the processing unit transitioning to and from the hibernated state may comprise DDR memory, for example.
[0055] [0055] With one processing unit in a hibernation state, the non-hibernated — processing unit may control device 110. For example, the non-hibernated processing unit may control the display via the display interface comprised in the non-hibernated processing unit. For example, where a less capable processing unit has caused a more capable processing unit to transition to the hibernated state, the less capable processing unit may provide a reduced user experience, for example, via at least in part, the display. An example of a reduced user experience is a mapping experience with a reduced visual experience comprising a black-and-white rendering of the mapping service. The reduced experience may be sufficient for the user to obtain a benefit from it, with the advantage that battery power is conserved by hibernating the more capable processing unit. In some embodiments, a more capable processing unit, such as a microprocessor, may consume a — milliampere of current when in a non-hibernated low-power state, while a less capable processing unit, such as a microcontroller, may consume only a microampere when in a non-hibernated low-power state. In non-hibernated states current consumption of processing units may be modified by setting an operating clock freguency to a value between a maximum clock freguency and a minimum non-zero clock freguency. In at least some embodiments, processing units, for example less capable processing units, may be configurable to power down for short periods, such as 10 or 15 microseconds, before being awakened. In the context of this document, this is not referred to as a hibernated state but an active low-power configuration. An average clock freguency calculated over a few such S periods and the intervening active periods is a positive non-zero value. A more capable N 25 — processing unit may be enabled to run the Android operating system, for example.
[0058] [0058] If the processing units reside in separate devices or housings, such as a wrist- top computer and a handheld or fixedly mounted display device for example, a bus may be implemented in a wireless fashion by using a wireless communication protocol. Radio transceiver units functionally connected to their respective processing units may thus — perform the function of the bus, forming a personal area network, PAN. The wireless communication protocol may be one used for communication between computers, and/or between any remote sensors, such as a Bluetooth LE or the proprietary ANT+ protocol. These are using direct-seguence spread spectrum, DSSS, modulation technigues and an S adaptive isochronous network configuration, respectively. Enabling descriptions of N 25 — necessary hardware for various implementations for wireless links are available, for I example, from the Texas Instrument®’s handbook “Wireless Connectivity” which includes = IC circuits and related hardware configurations for protocols working in sub-1- and 2.4- a GHz frequency bands, such as ANTTM, Bluetooth®, Bluetooth® low energy, RFID/NFC, PurePath™ Wireless audio, ZigBee®, IEEE 802.154, ZigBee RF4CF, 6LoWPAN, Wi- S 30 FiQ.N
[0059] [0059] In connection with hibernation, the PAN may be kept in operation by the non-hibernated processing unit, such that when hibernation ends, the processing unit leaving the hibernated mode may have access to the PAN without needing to re-establish it.
[0060] [0060] In some embodiments, microphone data is used in determining, in a first processor, whether to trigger a second processor from hibernation. The first processor may be less capable and consume less energy than the second processor. The first processor may comprise a microcontroller and the second processor may comprise a microprocessor, for example. The microphone data may be compared to reference data and/or preprocessed to identify in the microphone data features enabling determination whether a spoken instruction has been uttered and recorded into the microphone data. Alternatively or in — addition to a spoken instruction, an auditory control signal, such as a fire alarm or beep signal, may be searched in the microphone data.
[0061] [0061] Responsive to the spoken instruction and/or auditory control signal being detected, by the first processor, in the microphone data, the first processor may start the second processor. In some embodiments, the first processor starts the second processor into a state that the first processor selects in dependence of which spoken instruction and/or auditory control signal was in the microphone data. Thus, for example, where the spoken instruction identifies a web search engine, the second processor may be started up into a user interface of this particular web search engine. As a further example, where the auditory control signal is a fire alarm, the second processor may be started into a user interface of an application that provides emergency guidance to the user. Selecting the initial state for the second processor already in the first processor saves time compared to the case where the user or second processor itself selects the state.
[0062] [0062] In cases where a microphone is comprised in the apparatus, the microphone N may in particular be enclosed inside a waterproof casing. While such a casing may prevent 2 25 high-quality microphone data from being generated, it may allow for microphone quality = to be generated that is of sufficient quality for the first processor to determine, whether the E spoken instruction and/or auditory control signal is present.
[0064] [0064] In general, an instruction from outside the apparatus may be received in the apparatus, and the first processor may responsively cause the second processor to leave the hibernation state. The instruction from outside the apparatus may comprise, for example, the notification, the spoken instruction or the auditory control signal.
[0065] [0065] FIGURE 2 illustrates a first example apparatus capable of supporting at least some embodiments of the present invention. The illustrated apparatus comprises a microcontroller 210 and a microprocessor 220. Microcontroller 210 may comprise, for example, a Silabs EMF32 or a Renesas RL78 microcontroller, or similar. Microprocessor 220 may comprise, for example, a Qualcomm Snapdragon processor or an ARM Cortex- based processor. Microcontroller 210 and microprocessor 220 are in the example of FIGURE 2 communicatively coupled with an inter-core interface, which may comprise, for example, a serial or a parallel communication interface. More generally an interface disposed between microcontroller 210 and microprocessor 220 may be considered an inter- processing unit interface.
[0066] [0066] Microcontroller 210 is communicatively coupled, in the illustrated example, — with a buzzer 270, a universal serial bus, USB, interface 280, a pressure sensor 290, an acceleration sensor 2100, a gyroscope 2110, a magnetometer 2120, satellite positioning circuitry 2130, a Bluetooth interface 2140, user interface buttons 2150 and a touch interface 2160. Pressure sensor 290 may comprise an atmospheric pressure sensor, for N example.
[0068] [0068] Microcontroller 210 may be configured to determine whether triggering events occur, wherein responsive to the triggering events microcontroller 210 may be configured to cause microprocessor 220 to transition into and out of the hibernating state described above. When microprocessor 220 is in the hibernating state, microcontroller 210 may control display 230 via microcontroller display interface 222. Microcontroller 210 may thus provide, when microprocessor 220 is hibernated, for example, a reduced experience to a user via display 230.
[0069] [0069] Responsive to a triggering event, microcontroller 210 may cause microprocessor 220 to transition from the hibernated state to an active state. For example, — where a user indicates, for example via buttons 2150, that he wishes to originate a cellular communication connection, microcontroller 210 may cause microprocessor 220 to transition to an active state since cellular interface 240 is controllable by microprocessor 220, but, in the example of FIGURE 2, not directly usable by microcontroller 210. In some embodiments, when microprocessor 220 is hibernated, also cellular interface 240 is in a — hibernated state. Cellular interface 240 may comprise an electrical interface to a cellular transceiver, for example. Cellular interface 240 may comprise control circuitry of a cellular transceiver.
[0070] [0070] In various embodiments, at least two elements illustrated in FIGURE 2 may be integrated on a same integrated circuit. For example, microprocessor 220 and microcontroller 210 may be disposed as processing cores in a same integrated circuit. Where this is the case, for example, cellular interface 240 may be a cellular interface of this integrated circuit, comprised in this integrated circuit, with cellular interface 240 being controllable by microprocessor 220 but not by microcontroller 210. In other words, S individual hardware features of the integrated circuit may be controllable by one of AN 25 — microcontroller 210 and microprocessor 220, but not both. On the other hand, some + hardware features may be controllable by either processing unit. For example, USB z interface 260 and USB interface 280 may be in such an integrated embodiment one and the a . . N same USB interface of the integrated circuit, controllable by either processing core.
[0072] [0072] FIGURE 3 illustrates a second example apparatus capable of supporting at least some embodiments of the present invention.
[0073] [0073] Illustrated is device 300, which may comprise, for example, an embedded device 110 of FIGURE 1. Comprised in device 300 is processor 310, which may comprise, for example, a single- or multi-core processor wherein a single-core processor comprises one processing core and a multi-core processor comprises more than one processing core.

When computer instructions configured to cause processor 310 to perform certain actions are stored in memory 320, and device 300 overall is configured to run under the direction of processor 310 using computer instructions from memory 320, processor 310 and/or its at least one processing core may be considered to be configured to perform said certain actions. Memory 320 may be at least in part comprised in processor S 310. Memory 320 may be at least in part external to device 300 but accessible to device N 25 300. = [0075] Device 300 may comprise a transmitter 330. Device 300 may comprise a E receiver 340. Transmitter 330 and receiver 340 may be configured to transmit and receive, N respectively, information in accordance with at least one cellular or non-cellular standard. O Transmitter 330 may comprise more than one transmitter. Receiver 340 may comprise O 30 — more than one receiver. Transmitter 330 and/or receiver 340 may be configured to operate in accordance with global system for mobile communication, GSM, wideband code division multiple access, WCDMA, long term evolution, LTE, IS-95, wireless local area network, WLAN, Ethernet and/or worldwide interoperability for microwave access, WiMAX, standards, for example. Transmitter 330 and/or receiver 340 may be controllable via cellular interface 240, non-cellular interface 250 and/or USB interface 280 of FIGURE 2, for example.
[0076] [0076] Device 300 may comprise a near-field communication, NFC, transceiver 350. NFC transceiver 350 may support at least one NFC technology, such as NFC, Bluetooth, Wibree or similar technologies.
[0077] [0077] Device 300 may comprise user interface, UI, 360. UI 360 may comprise at least one of a display, a keyboard, a touchscreen, a vibrator arranged to signal to a user by — causing device 300 to vibrate, a speaker and a microphone. User input to UI 360 may be based on patterns, such as, for example, where a user shakes device 300 to initiate actions via UI 360. A user may be able to operate device 300 via UI 360, for example to accept incoming telephone calls, to originate telephone calls or video calls, to browse the Internet, to manage digital files stored in memory 320 or on a cloud accessible via transmitter 330 and receiver 340, or via NFC transceiver 350, and/or to play games. UI 360 may comprise, for example, buttons 2150 and display 230 of FIGURE 2.
[0078] [0078] Device 300 may comprise or be arranged to accept a user identity module
[0080] [0080] Device 300 may comprise further devices not illustrated in FIGURE 3. For example, where device 300 comprises a smartphone, it may comprise at least one digital camera. Some devices 300 may comprise a back-facing camera and a front-facing camera, wherein the back-facing camera may be intended for digital photography and the front- facing camera for video telephony. Device 300 may comprise a fingerprint sensor arranged to authenticate, at least in part, a user of device 300. In some embodiments, device 300 lacks at least one device described above. For example, some devices 300 may lack a NFC transceiver 350 and/or user identity module 370.
[0081] [0081] Processor 310, memory 320, transmitter 330, receiver 340, NFC transceiver 350, UI 360 and/or user identity module 370 may be interconnected by electrical leads internal to device 300 in a multitude of different ways. For example, each of the aforementioned devices may be separately connected to a master bus internal to device — 300, to allow for the devices to exchange information. However, as the skilled person will appreciate, this is only one example and depending on the embodiment various ways of interconnecting at least two of the aforementioned devices may be selected without departing from the scope of the present invention.
[0082] [0082] FIGURE 4 illustrates signalling in accordance with at least some embodiments of the present invention. On the vertical axes are disposed, from left to right, user interface UI, processing unit PUI, processing unit 2 PU2, and finally display DISP. Time advances from the top toward the bottom. Processing unit 2 may have higher ES processing capability, and be associated with a higher current consumption, than N processing unit 1.
[0085] [0085] In phase 460, a user interacts with the user interface UI in such a way that — processing unit 1 determines a triggering event to transition processing unit 2 from the hibernated state to an active state. For example, the user may trigger a web browser application that reguires a connectivity capability that only processing unit 2 can provide. Responsively, in phase 470 processing unit 1 causes processing unit 2 to wake up from the hibernating state. As a response, processing unit 2 may read a state from a memory and — wake up to this state, and assume control of the display, which is illustrated as phase 480.
[0086] [0086] FIGURE 5 is a first flow chart of a method involving two processing cores in accordance with at least some embodiments of the present invention. The phases of the illustrated method may be performed in device 110 of FIGURE 1, or in the apparatus of FIGURE 2, for example.
[0087] [0087] Phase 510 comprises generating, by a first processing core, first control signals. Phase 520 comprises controlling a display by providing the first control signals to the display via a first display interface. Phase 530 comprises generating, by a second processing core, second control signals. Phase 540 comprises controlling the display by N providing the second control signals to the display via a second display interface. Finally, = 25 — phase 550 comprises causing the second processing core to enter and leave a hibernation - state based at least partly on a determination, by the first processing core, concerning an = instruction from outside the apparatus.
[0089] [0089] PUI corresponds to processing unit 1, for example, a less capable processing unit. PU2 corresponds to processing unit 2, for example, a more capable processing unit.
[0090] [0090] Starting from the initial power-off state, first PUI is powered up, indicated as a “1” in the state of PUI, while PU2 remains in an off state, denoted by zero. Thus the compound state is “10”, corresponding to a case where PUI is active and PU2 is not. In this state, the device may offer a reduced experience to a user and consume relatively little current from battery reserves.
[0091] [0091] In addition to, or alternatively to, a power-off state PUI and/or PU2 may — have an intermediate low-power state from which it may be transitioned to an active state faster than from a complete power-off state. For example, a processing unit may be set to such an intermediate low-power state before being set to a power-off state. In case the processing unit is needed soon afterward, it may be caused to transition back to the power- up state. If no need for the processing unit is identified within a preconfigured time, the processing unit may be caused to transition from the intermediate low-power state to a power-off state.
[0092] [0092] Arrow 610 denotes a transition from state “10” to state “117, in other words, a transition where PU2 is transitioned from the hibernated state to an active state, for example, a state where its clock frequency is non-zero. PUI may cause the transition denoted by arrow 610 to occur, for example, responsive to a triggering event. In state “11”, the device may be able to offer a richer experience, at the cost of faster battery power consumption. N [0093] Arrow 620 denotes a transition from state “11” to state “10”, in other words, 2 a transition where PU2 is transitioned from an active state to the hibernated state. PUI may s 25 — cause the transition denoted by arrow 620 to occur, for example, responsive to a triggering = event. a N [0094] FIGURE 7A illustrates an example user interface in accordance with at least O some embodiments of the present invention. The user interface may be comprised in O device 110 of FIGURE 1A or FIGURE 1B, for example. Display 700 is configured to provide a user interface display to the user. Display area 710 provides an application level display to the user. In application level display 710 is comprised a map 720, which may display, for example, terrain and/or elevation information. In the illustrated example, a hill is displayed in the map 720.
[0095] [0095] According to some embodiments, the user may be presented with a selection of updated heatmaps created for different sports activities in locations outside, but adjacent to said present location. Thus the display 700 may show a map 720 with a hill in a neighbouring town, county or borough, for example. The rule of what is within the present location of the device 110 and what is in adjacent location may be set by the boundaries between such areas, if the positioning system used contain such data, or simply by a radius form the present location, e.g. 10 km.
[0096] [0096] Some activities preferred by the user, such as cycling for example, may involve moving long distances and/or for a lengthy time. In the planning of such activities it may be beneficial to have heatmaps also covering locations nearby the present one.
[0099] [0099] The user may be presented with information concerning route options, for example for the first option, an estimated energy consumption associated with an activity session along the route defined by the first option, and likewise for the second option. The user may, explicitly or implicitly, select one of the presented options, and along the route deviate therefrom to use a different set of route segments. For example, a user setting on — along the first option, may decide to shorten the activity session by taking segments 750e and 750d back to the start point 730. Alternatively, the user may decide to lengthen the session by taking, in the first option, segment 750f instead of segment 750b.
[00100] [00100] In some embodiments, information is presented separately concerning route segments, to enable the user to design a route with greater precision. For example, an energy consumption associated with segment 750a, when used as a route segment in an activity session of a given type, may be presented. Likewise, other physiological effects, such as EPOC or oxygen consumption, may be presented in addition to, or alternatively to, the energy consumption.
[00101] [00101] FIGURE 8 is a flow graph of a method in accordance with at least some embodiments of the present invention. The phases of the illustrated method may be performed in device 110, for example, or in a control device configured to control the functioning of device 110, when implanted therein, for example.
[00104] [00104] Phase 900 comprises determining the present location of the apparatus. Phase 910 comprises the action of transmitting from said apparatus a query to a thematic map database server. The query may comprise an indication of the current location of the apparatus. In phase 920 the device 110 is updated with thematic maps related to the location by downloading thematic map data and storing the thematic map data in a memory of the device. In phase 930 the user is presented in a first display mode with a selection of local thematic maps as suggested activity types. The thematic maps may be selected to be — downloaded based on at least one of the following criteria: a pre-recorded user preference, user activity history, intensity of activities in said location, special activities in said location, time of the day, time of the year, or a second location adjacent to said present location. Finally, in phase 940 and in response to the user approving a suggested activity type, an activity session is initiated and displayed in a second display mode.
[00105] [00105] In FIGURE 10 is shown an exemplary hardware configuration of a two- processor wristwatch- type device 1000, which is able to support at least some embodiments of the invention. A high-power first microprocessor or a microcontroller unit (MCU) 1020 comprising a first processing core and a low-power second application processor (AP) or a microcontroller unit 1030 comprising a second processing core are shown. Alternatively, the two or more processing cores with different characteristics may reside within the same microprocessor 1020. Both processors (or cores) are able to control a device display 1010 and to show information on the display 1010, as indicated by arrows S A and B, respectively. The display 1010 may be a touch-screen display. A sensor, such as a N 25 — GPS sensor (not shown, see e.g. item 2130 in FIG. 2) provides location information to at = least one of the processing cores, enabling the device to determine its location. < = [00106] During normal operation, when thematic maps, which may be downloaded a N from the server 1070 through a communication interface 1022 of the first processor 1020, A of suggested activities is presented to a user on the display 1010, the device 1000 assumes N 30 a first activity display mode controlled by the first processor 1020. The communication N interface 1022 may correspond to any or several of the interfaces 240 — 260 of FIGURE 2, for example. The selection of an activity session may have been based on user selection input, a pre-recorded user preference, user activity history, intensity of activities in said location, special activities in said location, time of the day, time of the year, or a second location adjacent to said present location.
[00107] [00107] The first processor 1020 initiates the selected activity and displays to the user in the first activity display mode performance-related information relating to physical performance of the user, including sensor information relating to position, distance, speed, heart rate etc. This fist activity mode is active for a predetermined time, or ends when, for example, acceleration sensor information indicates that the user is in a steady performance mode, based on cadence, rhythmic movements, heart rate, etc.
[00108] [00108] The first processor 1020 may then produce a reduced version of the thematic map of a selected activity, or the reduced maps may be downloaded from the server 1070 on demand. The demand may be based on the type of the device, the preferences of the user and/or the location of the user, and the server provides the appropriate selection of activities for downloading.
[00111] [00111] Reduced thematic maps may be downloaded from the server 1070, or they may be produced by the first processor 1020 and stored in its memory 1021. In a two- processing core embodiment, the image(s) of the reduced thematic map may be copied (arrow C in Fig. 10) to a memory 1031 of the low-power second processor 1030, to be shown therefrom in a second display mode.
[00112] [00112] As the performance of the user continues on a steady path and there is no indication of the user looking at the display, the device 1000 may enter a second power- save mode by switching off the second display mode and putting the second processing core 1030 in a hibernating mode.
[00113] [00113] In a second power-save mode, the only process running in the device may be the real time clock in the RTC unit 1060. The RTC unit is preferably a separate unit connected to a battery of the device, for example. The processing cores may then be completely shut off. RTC units may also be integrated in either one of the processors 1020 — or 1030, or in both, but would then require at least some hardware around the processor in guestion to be powered up, with a power consumption of a few microamperes. Which alternative RTC units to use is a matter of design choice.
[00114] [00114] In a one-processor embodiment, the transfer of maps internally in the device is of S course not needed, otherwise a second display mode may be used in the same fashion as N 25 — with two processors, and the reduced thematic map is then shown from the memory 1021 = on the display 1010. The single processor may thus have three levels of operation and = power consumption: full operation, reduced operation and hibernation (with or without an E internal RTC clock). During the performance, an acceleration sensor 1040 may N continuously sense the movement of the device 1000. In some embodiments, the processor O 30 may be left in a reduced operation mode, if the activity and/or context are deemed to O reguire a fast wakeup of the core. Wakeup from a state of hibernation will take longer. Various power-saving modes may also be entered when the device 1000 deems the user is sleeping, for example. Indeed, various sensor inputs and their combinations may be used for determining the context of the user and select an appropriate time to enter a particular power-save mode. Such input may include the time (e.g. night-time), acceleration sensor input, ambient light, position signals from a GPS sensor, etc.
[00115] [00115] Reversing the power-saving sequence may be initiated simply by a user pressing a button, or it may be automatic. In some embodiments, for example, when a vertical move is sensed by a smart acceleration sensor 1040, the corresponding sensor signal may have pre-recorded threshold values that when exceeded are interpreted as a raise of the arm in an attempted reading of the display 1010. A power controller 1050 then powers up the high-power processor 1020, or the low-power processor 1030, depending on the embodiment (one or two processors) and the previous context or display mode of the device 1000). In order to speed up the wakeup of hibernating processing cores, their power supplies (switched-mode power supply SMPS, for example) may be left on. Another alternative embodiment is to switch the SMPS off and connect a low-dropout (LDO) regulator as a fast power source for the hibernating processing core in parallel over the SMPS.
[00116] [00116] In some embodiments, the RTC unit may also start a processor. For example, if a relatively long time has passed since the user last made an attempt to look at the display, the context is difficult to predict and may have changed. The user would then no longer be interested in looking at a reduced thematic map that probably does not show the correct location and/or activity of the user anymore. Instead of just fetching for display a stored thematic map relating to a wrong context, the time delay since the last display action may be used as an indicator that the context has probably changed. As the RTC unit S reveals this time delay, the information may be used for example to activate a GPS sensor N 25 in order to check the location and start at least a low power processor to update the context = of the user, including fetching a thematic map which matches the current location of the = user. i N [00117] The context- dependent images may be fetched from a memory by using a A LDO regulator as the power source for a hibernating processor, which provides a fast N 30 wakeup. After wakeup, transfer of stored images may take place directly from an internal N memory of the processor or from an external memory unit to the display.
[00118] [00118] Reference is now made to FIGURE 11, which shows a flowchart of the main steps performed by an apparatus according to the invention. The apparatus comprises at least two processing cores, at least one display with at least two display modes, at least one memory including a computer program code.
[00119] [00119] In step 1110, the present location of the apparatus is determined and a query is transmitted from the apparatus to a thematic map database server for available activity or thematic maps at the current location of the apparatus.
[00120] [00120] In step 1120, the apparatus is update with thematic maps related to the current location from the thematic map database server, by downloading thematic map data and storing the thematic map data in said at least one memory of the apparatus.
[00121] [00121] At least one downloaded thematic map is presented to a user of the apparatus — asa selection of local heatmaps as a suggested activity in step 1130, using a first activity display mode, as presented by a high-power first processing core. The activity session may be selected based on at least one of the following criteria: user selection input, a pre- recorded user preference, user activity history, intensity of activities in said location, special activities in said location, time of the day, time of the year, or a second location adjacent to said present location.
[00122] [00122] In step 1140, a selected activity is initiated and displayed to the user in the display mode, containing performance-related information relating to physical performance of the user in the activity.
[00124] [00124] Finally, in step 1160 a second power-save mode is entered by switching off the second display mode and putting also the low-power second processing core in a hibernating mode. A third display mode is entered, where a Real Time Clock (RTC) unit is used to keep the time. Pre-stored thematic maps may be shown when requested by a user input or a sensor request, showing the predicted location of the user on the map at that time.
[00125] [00125] The apparatus may now go stepwise back to the second and/or first display modes by activating the second and/or first processing cores from hibernation. This may be triggered on at least one of the following criteria: user selection input, acceleration data input from an acceleration sensor in said apparatus indicating a display reading posture of said user.
