    Interaction symbol display and management method and associated touch-sensitive display device
    The field of the invention is that of the presentation and management of interactions called Man-System or "IHS" tactile cockpit aircraft.
    Currently, the traditional means of interaction in an aircraft cockpit are, in most applications, mechanical interactors. Thus, FIG. 1 shows a control station 10 according to the prior art comprising: finite state rotators 11 comprising a limited number of positions; - Rotators with continuous values 12 for adjusting a parameter such as, for example, a noise level; - Simple buttons 13 or "toggle buttons" exclusive or not, with or without visual feedback; switches 14 or "switches" for implementing or stopping functions.
    These traditional means are gradually replaced by virtual interactors displayed on display devices having tactile surfaces and which provide the same functions. This solution has many advantages in terms of cost, size, flexibility and reconfiguration. However, these tactile interactors must respect a certain number of recommendations specific to the aeronautical world. In particular, they must: - Offer an ergonomic graphic representation. This can be close to that of the traditional buttons as shown in the different figures. But, it is possible to use different graphic representations adapted to both the function and tactile manipulation; - Provide a relevant information display, legible and space-saving; - Offer intuitive, effective interaction modes and blind value adjustments; - Secure critical tactile interactions; - Allow effective interaction even in degraded weather conditions, that is to say in case of turbulence.
    Solutions have been proposed to address this problem. In particular, publication US 2013/0249814 entitled "Adjustment mechanisms for virtual knobs on a touchscreen interface" which describes a touch interface principle intended to replace a physical rotator in the following manner. The function "push / pull" to switch from one mode to another is replaced by "clicks" extended on a graphical representation of the physical rotator. On a simple click of the user, the screen displays an interactive ring around the virtual rotator. This interactive ring allows a circular interaction in the clockwise or anti-clockwise direction to increment or decrement a parameter associated with the rotator. The drawbacks of this solution are the following: bulky graphic representation and poorly adapted to positioning at the edge of a display screen; - Preservation of the rotary movement to keep an interaction close to the existing one. However, this type of movement on a touch screen is neither very ergonomic nor very effective; - No adaptation of the rotator to the selection of finite states; - Interaction poorly adapted to use in turbulent conditions; - Fixed level of adjustment.
    The method of displaying and managing interaction symbols according to the invention does not have these disadvantages.
    It is primarily intended for aircraft dashboards but can also be applied to other technical fields. In this aeronautical framework, it makes it possible to replace all the types of physical interactors present in an aircraft. It reduces the level of learning and the training required to master the human / system interface by preferably offering graphic representations similar to the physical interactors known to pilots. This greatly facilitates the reading and recognition of information.
    Virtual interactors according to the invention are also secured and adapted to aeronautical operational requirements. They control the level of precision of a numeric value selection. The gestures to be made to change state are simple, effective and adapted to the use of a touch screen. These new interactors also offer additional capabilities over physical interactors such as state selection on multiple hierarchical levels. They are more specifically dedicated to the simulation of rotators.
    More specifically, the subject of the invention is a method for displaying and managing interaction symbols in a display system comprising at least one display device comprising a touch-sensitive surface and means for displaying, managing and controlling associated, said method arranged to manage at least one graphical interactor for performing at least the functions of a rotator, characterized in that said display and management method comprises at least the following steps: - Step 1: in the absence of tactile solicitation, displaying a symbol representative of the current state of said rotator; - Step 2: on a first tactile solicitation, appearance of interaction icons dedicated to said rotator and surrounding said symbol; Step 3: by maintaining and moving the tactile solicitation on the different interaction icons, changing the current state of said rotator; - Step 4: by stopping the tactile solicitation, validation of the new current state and disappearance of the interaction icons.
    Advantageously, said rotator being a finite state rotator, the method comprises the following steps: Step 1: in the absence of tactile solicitation, the symbol is surrounded by a plurality of indications representing the various possible states and disposed substantially on a first arc surrounding said symbol, said symbol having a marker designating a first indication representing a first state, said display being called a current display; Step 2: on a first tactile solicitation, replacement of the indications by icons representing the different possible states arranged substantially on a second circular arc surrounding said symbol and having a radius greater than the first circular arc and appearance of a pellet at the place of tactile solicitation; - Step 3: By maintaining and moving the tactile solicitation, moving the pellet on the various icons until the representative icon of a second selected state; - Step 4: By stopping the tactile solicitation, selecting said second state, return to the current display, the marker being positioned on the second selected state.
    Advantageously, step 3 is followed by a step 3bis in which at least the selection of a particular icon representing a particular state causes the appearance of secondary icons surrounding said icon, each of said secondary icons representing different secondary states associated with the said particular state.
    Advantageously, said rotator being a continuous state rotator, the method comprises the following steps: Step 1: in the absence of tactile solicitation, the displayed symbol is representative of a value called current value; - Step 2: on a first tactile solicitation, appearance of two elongated icons symmetrically disposed on either side of the symbol along an axis, the first icon with the sign "+" and the second icon with the sign "-"; - Step 3: By maintaining and moving the tactile stress in a direction substantially parallel to said axis, increasing or decreasing the current value to a determined value; - Step 4: By stopping the tactile solicitation, selection of said determined value and return to the current display.
    Advantageously, the further the bias moves away from the center of the axis corresponding to the center of the symbol, the more the increase or decrease of the current value is rapid.
    Advantageously, step 4 is followed by a security step 4bis comprising a brief tactile solicitation called "tap".
    Advantageously, the tactile surface comprises haptic means.
    Advantageously, the symbol is circular in shape and has the graphic appearance of a mechanical rotator. The invention also relates to a display system comprising at least one display device comprising a touch surface and associated display, management and control means, said display system comprising electronic and digital means of implementation of a graphical interaction management method for performing at least the functions of a rotator, characterized in that said display and management method comprises the following steps: - Step 1: in the absence of tactile solicitation, display a symbol representative of the current state of said rotator; - Step 2: on a first tactile solicitation, appearance of interaction icons dedicated to said rotator and surrounding said symbol; Step 3: by maintaining and moving the tactile solicitation on the different interaction icons, changing the current state of said rotator; - Step 4: by stopping the tactile solicitation, validation of the new current state and disappearance of the interaction icons. The invention will be better understood and other advantages will become apparent on reading the description which follows given by way of non-limiting example and by virtue of the appended figures among which:
    Figure 1 already described represents a control station according to the prior art;
    Figures 2, 3, 4 and 5 show the different steps of the method according to the invention in the case of the simulation of a finite state rotator;
    Figures 6 and 7 show alternative embodiments of the preceding finite state rotator;
    FIG. 8 represents a continuous state rotator according to the invention;
    FIG. 9 represents the variations of a value represented by the preceding continuous state rotator as a function of the distance of the bias.
    The method for displaying and managing interaction symbols according to the invention is implemented in a display system comprising a display device comprising a touch surface and display, management and associated control means. Generally, the display device is a liquid crystal display device but, of course, it can adapt to other types of displays. There are different types of touchscreen. Examples include resistive or capacitive touch panels. The graphic management means are adapted to implement the various steps of the method.
    The display and management method according to the invention is particularly applicable for performing the same functions as mechanical rotators. It comprises the following steps: - Step 1: in the absence of tactile solicitation, display of a symbol representative of the current state of said rotator; - Step 2: on a first tactile solicitation, appearance of interaction icons dedicated to said rotator and surrounding said symbol; Step 3: by maintaining and moving the tactile solicitation on the different interaction icons, changing the current state of said rotator; - Step 4: by stopping the tactile solicitation, validation of the new current state and disappearance of the interaction icons.
    This method can be applied to simulate finite state rotators or continuous state rotators. By way of non-limiting example, FIGS. 2, 3, 4 and 5 represent the various steps of the method according to the invention in the case of the simulation of a finite state rotator. In these figures, the rotator comprises four states denoted "THRT", "ALL", "ABV" and "BLW". The number of states can be different.
    In a first step 1 shown in FIG. 2, in the absence of tactile bias, a representative symbol of the rotator is displayed. It's a circle on this figure. Of course, the symbol may have different shapes, colors and shades to make it look like a traditional mechanical rotator. It is surrounded by four indications representing the various possible states noted "THRT", "ALL", "ABV" and "BLW". These indications are arranged substantially on a first arc surrounding the symbol 20. This symbol comprises a marker 21 designating a first indication representing a first state, said display being called current display. In the case of Figure 2, this marker is an elongated rectangle and designates the state "BLW". It can take other forms such as, for example, arrowheads.
    In a second step shown in FIG. 3, on a first tactile solicitation which corresponds to a user's finger touching the tactile surface at the location of the displayed symbol, the preceding indications are replaced by icons 22 representing the different states. possible arranged substantially on a second circular arc surrounding said symbol and radius greater than the first arc. In FIG. 3, the icons 22 are circles surrounding the states denoted "THRT", "ALL", "ABV" and "BLW". Again, different shapes, colors, shading are possible. It is important that these icons have a width greater than one centimeter so as to allow interaction that does not require significant positioning accuracy on the part of the user.
    Symbolically, the spacing of the icons is represented by double chevrons in Figure 3. A tablet 23 appears on one of the icons. It is represented by a triple circle in FIGS. 3 and 4. Other graphic representations are possible. At this point, it is possible to add a delay so that the transition to interactive mode of selection of states is not immediate.
    In a third step shown in FIG. 4, the pad is held and moved by tactile bias to the icon representative of a second state that one wishes to select. In the case of Figure 4, it is the state "ABV".
    In a fourth and last step shown in FIG. 5, the tactile solicitation is stopped. The second state is selected. The display returns to the current display with the marker positioned on the second selected state. In this case, it is the state "ABV".
    It should be noted that the interactions according to the invention are secure. Indeed, a simple "tap" can not change the state of the interactor. In case the user unintentionally releases his finger, we can secure the validation by a double "tap" or a "tap" with a second finger in the case of touch screens called "multitouch" for interaction with multiple fingers.
    This type of rotator can be used to select a value. For example, Figure 6 shows the selection of a value between 0 and 360 in increments of 45. The symbol 20 is surrounded by 8 icons 24 marked 45 in 45. Once a value is selected, we can then refine it by other means. In Figure 6, the value "45" is selected.
    It is also possible to incorporate additional functions that can not be reproduced with a physical interactor. Thus, from a selected state, it is possible to have access to sub-states according to a tree hierarchy. To pass from a state to the corresponding sub-states, one carries out, for example, a prolonged support or a "tap" or a "double" tap "or a" slide "with another finger. The term "slide" is understood to mean the operation of sliding the finger on the tactile surface for a certain distance. The goal is not to release your finger before the end of the interaction. For example, in Figure 7, the choice of the value "45" shows other values arranged in icons 25 between 10 and 50. It is easy to navigate in the tree. The return is done simply by returning to the original icon.
    The method according to the invention also makes it possible to simulate a continuous state rotator, that is to say a rotator for finely adjusting a value. For example, it is possible to adjust the value of a radio frequency or a sound level or a zoom ratio on a cartographic representation. In this case, the method comprises the following steps: Step 1: in the absence of tactile solicitation, the displayed symbol is representative of a value called current value; - Step 2: on a first tactile solicitation, appearance of two elongated icons symmetrically disposed on either side of the symbol along an axis, the first icon with the sign "+" and the second icon with the sign "-". By way of example, FIG. 8 represents the central symbol 26 surrounded by these two icons. The axis is denoted x in this FIG. 8; - Step 3: By maintaining and moving the tactile stress along said axis, increasing or decreasing the current value to a determined value; - Step 4: By stopping the tactile solicitation, selection of said determined value and return to the current display. The orientation of the x-axis is preferably chosen according to the associated graphical return. For example, a level adjustment is made along a vertical axis while the axis of a cursor is horizontal.
    The icons may have a width greater than one centimeter to allow interaction that does not require significant positioning accuracy on the part of the user. It is also possible to perform the "blind" interaction outside the icon area provided the interaction is in the same direction as the x-axis. Indeed, changing the value of the parameter is usually accompanied by a perceptible effect such as a change in brightness or a change in sound volume. It is therefore not necessary for the user to precisely control the interaction insofar as he immediately perceives the effects. The incrementation of the value can be done linearly. However, it is preferable that the rate of change increases as the distance from the center of the x axis increases. The further the bias moves away from the center of the axis corresponding to the center of the symbol, the faster or faster the current value increases or decreases. During turbulence, it is important to have a quadratic type acceleration to avoid excessive speed variations on the fine adjustments. This point is illustrated in FIG. 9, which represents the variation of the incrementing speed "I" as a function of the distance at the center of the x-axis. It is weak at the center and important at the ends.
    To facilitate these interactions blindly, it is possible, if the display device allows, to add a haptic effect to the borders of the interaction zone to avoid unintentionally leaving it and to determine intuitively how distance from the center the finger of the user is located.
    The advantages of the method for displaying and managing interaction symbols according to the invention are mainly: - Securing tactile interactions; - Limitation of additional learning times / workouts; - Ergonomic and effective interactions; - Simple adaptation of tactile interfaces to all operational needs.
