    description
    The invention relates to a computer system and a control method therefor.
    The computer system according to the invention has a data processing unit, a touch-sensitive, position-resolving input surface and a freely movable input device with which the input surface is to be touched for input to the data processing unit.
    In EP 1050015 Bl, a common principle for a so-called " optical computer mouse " described. The input device is slidably guided on a surface. It illuminates a small surface area of the surface, captures images of the illuminated surface area and calculates the positional shift that has taken place on the basis of the displacement of temporally successive image elements recognized as identical. The device is well suited for measuring from a single point the relative displacement of the input device on a surface. If the housing is executed in the form of a pen, so that the movements which are required when writing in handwriting, can be performed well and thus handwriting already recorded during the writing process.
    US 4464652 A shows a so-called "mechanical computer mouse". In this case, a ball rolls off with a projecting from a housing part of its surface on a surface. The rotation of the ball relative to the housing about two normal axes is measured and output as information about the change of two coordinates.
    In US 5,371,516 A, the described principle of the " mechanical computer mouse " realized on a device which has approximately the shape of a pen, wherein the ball is relatively small and is arranged at the top. You can do it better than WITH REPLACEMENT | IQ17
    Computer mice of conventional form typing lines of handwriting or hand sketches into a computer.
    A computer mouse in the sense of this document is a freely movable input device which is in data transmission connection with a data processing unit, which measures relative displacement to a surface on which it is moved by means of a position change sensor in two coordinates and transmits the measurement data to the data processing unit.
    WO 2007046604 A1 shows an input device which has approximately the shape of a writing pen. It contains several independent sensor devices for measuring a change in position. A sensor device is based on the principle of " optical computer mouse " (as discussed above), other sensor devices are inertial sensors. As a result, the input device is functional even when it is lifted from a surface. A touch sensor detects whether the device is touching a surface or not. When it touches the surface it automatically switches to the operating state " optical computer mouse " In particular, handwriting or hand drawings can be very good already during the emergence.
    WO 2010006348 A1 and WO 2010118450 A1 show a computer system which is to be controlled by a photosensitive position-sensitive input surface. The input surface is a planar optical waveguide and the movable input device is a pointing device, which emits a light beam. The light incident from the pointing device on the input surface causes, by luminescence, longer wavelength light in the waveguide mode whose intensity decreases with distance to the point of impingement of the causing light. In several places on the input surface small-scale photoelectric sensors are mounted, at which electrical signals are generated, the signal strength of

    SUBJECT IQ17 depends on the local intensity of the light in the waveguide mode and from which the point of incidence of the causing light is deduced. Since the input area can also be the output area for image information output by the data processing unit, the pointing device can also set the absolute position of a processing mark (a "cursor") well from a distance. Small movements of the processing mark, as they occur, for example, when using the pointing device, which may have the shape of a pen, at the input area " handwritten " is, but are only well metrologically detectable, if the input surface allows a very high position resolution. Especially with input surfaces that are sufficiently large to serve as the output surface of the data processing unit for presentation in front of a larger auditorium, such a high position resolution capability can be provided only with a very high hardware cost.
    For the purposes of this document, a touch-sensitive, position-resolving input surface is a surface which is provided with sensors such that, when touched by an object, it provides a sensor signal to a data processing unit indicating that it is being touched and which position coordinates are the touch point on her. Usually, the coordinates of a processing mark (usually referred to as "cursor") on a display area controlled by the data processing unit are calculated by the data processing unit from the position coordinates communicated to the data processing unit and the processing mark is positioned on the display area accordingly.
    There is a wealth of suggestions and sophisticated techniques for realizing touch-sensitive, position-resolving input surfaces. Likewise, there are plenty of suggestions and sophisticated techniques for making a computer mouse by combining it
    Page 3 REPLACED | IQ17 to be replaced by a touch-sensitive, position-resolving input surface and a stylus. Instead of generating position change data by moving a mouse on a surface and reading it to a data processing unit, the coordinates of the point of contact of the pen (or a finger) with the input surface are measured and read to the data processing unit. Examples thereof are shown in DE 10110744 A1, US Pat. No. 6,128,007 A, DE 9316194 U1, GB 2266038 A, US 2004150632 A1, WO 2005096217 A1 and KR 100859010 B1.
    Compared to a real computer mouse, there is the advantage that the absolute position of a cursor can be fixed immediately, because it can be easily associated with the input surface according to a fixed rule of the absolute position of the point of contact of the pen or finger.
    The disadvantage is that the sensitivity for small displacements of the contact point is limited by the position resolution capability of the input surface. Frequently, a touchscreen is used as the touch-sensitive, position-resolving input surface, ie a surface which, in addition to the sensor function discussed, also has the function of a display surface for a data processing unit. Especially for very large touch screens. For reasons of affordability, not too fine a position resolution capability is installed. Then there can be very disturbing restrictions, especially when entering handwriting or creating fine hand drawings. Inadequate position resolution capability often results in the additional difficulty of not being able to see through the data processing unit whether one or more touch points are present on the input surface, that is, if " written " or " drawn " becomes.
    The object underlying the invention is to provide the position resolution capability in the input by means of input data.
    page 4
    FULFILLED IQ17 to improve without having to equip the input surface increasingly with sensors. For solving the problem, it is proposed to provide a computer mouse as a freely movable device, with which the touch-sensitive, position-resolving input surface is to be touched for input to the data processing unit, and also to read the data generated by this computer mouse into the data processing unit.
    Nowadays, the cost-effective and excellently engineered computer mice ("computer mouse" definition, see above) have very good position resolution capability compared to large touchscreens and are very cost effective compared to other comparably powerful position sensors.
    Since the input surface is positionally sensitive to touch, the position of an input mark can be immediately fixed and detected on it, without the input mark having to be aligned as from a display edge, as in a computer mouse.
    By having the free-moving input device itself a position change sensor with high position resolution capability, position changes too fine for the position resolution capability of the sensitive input surface are also well detectable.
    Preferably, the computer mouse has the form of a pin, wherein the position change sensor is arranged at a tip of the pin. Thus, the computer mouse can be moved by a person using them comfortably as a writing or drawing pen. Hand drawings and manuscripts are thus comfortable even while applying to the input surface regardless of the position resolution capability of the input surface well read into the data processing unit.

    REPLACED IQ17
    Preferably, the computer mouse has a sensor function, by which it is detected whether it is applied to a surface or not. Almost all commercially available computer mice today have such a sensor function, which is why the exact technical design need not be discussed here. When the computer mouse is placed on the input surface, information is sent to the data processing unit by both the computer mouse and the input field. The information sent by the computer mouse indicates that the computer mouse has come into contact with a surface. The information sent by the input surface describes the coordinates of a touch point just created. Due to the temporal proximity of the arrival of the two pieces of information at the data processing unit, it can be seen for them that the sending computer mouse is exactly at the specific touch point. Thus, in the case of temporally overlapping use of multiple computer mice on the same data processing unit and on the same input area for the data processing unit, the individual computer mice are very well distinguishable and clearly recognizable.
    Even with the displacement of the points of contact of several computer mice on the input surface, the individual computer mice for the data processing unit remain clearly recognizable because each computer mouse through the input surface continuously absolute position data are sent and relative position change data sent by the computer mice themselves continuously and because the two data correlate with each other have to describe, ie at the same time about the same places and about the same directions of movement.
    In the most preferred embodiment, the computer mouse has an optical sensor for positional changes against an area along which it slides. (The relevant sensor principle is, for example, in the aforementioned EP
    page 6
    For example, the principle of the aforementioned US Pat. No. 5,371,516 A certainly makes sense, according to which a " mechanical computer mouse " is realized in the outer form pen.
    For the purposes of this document and thus also in the sense of the present inventive concept, such input surfaces are also to be regarded as touch-sensitive, position-resolving input surfaces which strictly speaking do not directly detect the contact with an object, but only the very close approach of an object to a point on its surface. For example, such a " touch " Spatial resolution input surface be realized by just before her and aligned parallel to her a light curtain {ie, one of the line shape in the surface shape of extended light barriers) is arranged, which an object penetrates forced, so interrupts when it touches the input surface.
    The invention is illustrated by means of a sketch:
    Fig. 1: shows the wesentli for understanding the invention chen devices of an exemplary computer system according to the invention. Data connections are shown as dashed lines with a directional symbol.
    The computer system shown in FIG. 1 has a data processing unit 1, an input surface 2 designed as a touch screen, and a computer mouse 3.
    Image information generated in the data processing unit 1 is output via the input surface 2 designed as a touchscreen. Control information to the data processing unit 1 is generated both by the input surface 2 and also by the computer mouse 3 and sent to the data processing unit 1.
    j 'FAILED IQ17
    Advantageously, during the input to the data processing unit 1 at regular intervals by means of mathematical interpolation the information sent by the input surface 2 to the data processing unit, the absolute position of the computer mouse 3 data with the data sent from the computer mouse 3 data adjusted, which the relative position changes For example, good interpolation methods can be easily determined by experiment. The aim and result of this alignment is to set the position of the machining mark so that this position represents a good compromise between the position of the computer mouse measured by the input surface and the position of the computer mouse measured by the computer mouse itself. If this is successful, the editing mark is always near the top of the computer mouse 3, even with long, continuous input operations, and still makes good use of small fine movements of the computer mouse.
