To this end, it is proposed to develop physical control contacts on touch screens of the simulator that are configured to provide data for adjusting the display of said screens. A front control panel (10) of such a simulator comprises, according to one embodiment, a keyboard (2, 2L, 8, 9) provided with interactive members (20) for forming a pad (30), and a touch screen (1).

Description

METHOD FOR INTERACTING BETWEEN INTERACTION DEVICES AND TOUCH SCREEN, CONTROL PANEL AND TERMINALS PROVIDED WITH SUCH FACADES

DESCRIPTION

TECHNICAL AREA

The invention relates to a method of interfacing between interaction members - actuators, lights, audible or visual alarms, or other equivalent function bodies - and a touch screen in contact in order to transmit interaction data. The invention also relates to a control panel (hereinafter referred to as a "front panel") comprising interaction members housed in a chassis and a touch screen interfaced according to this method, as well as a control and / or control terminal. provided with at least one such facade. The invention applies in particular, but not exclusively, to an aircraft flight simulator.

The field of the invention is more particularly in the driving simulation for learning, training, qualification or training in new equipment, including control assemblies and / or command with a Human-System (IHS) or Man-Machine (HMI) dialogue interface, hereinafter referred to as "terminal". In addition to the aeronautical field, the invention can be applied in a variety of fields: building, surgery, rail, road, maritime or fluvial environment, low vision, etc.).

[0003] The aircraft flight simulation equipment reconstitute a cockpit of piloting conventionally combining several panels, the main control panel located in front of the pilots (the "dashboard"), the lower management panel of the flight guidance located between the pilots (also called "pylon"), the upper circuit management panel extending above the pilots and the autopilot panel located in the awning, above the main panel. These panels include control screens in conjunction with actuators (buttons, switches, switches, levers, etc.) for adjusting, selecting, tripping / stopping control, command and flight guidance systems, as well as lights and / or alarms.

Thus, the main control panel generally gathers the control screens (navigation screens, engine control, primary flight with attitude, altitude and heading, control screen circuits: hydraulic, electrical, ventilation, etc.) as well as certain controls, such as landing gear input / output lever and automatic brake control.

The bottom panel generally integrates the multiple control display units (or "MCDU", acronym for "Multi Control Display Unit" in English terminology) in connection with the on-board computer in a real cockpit, as well as joysticks engine thrust (one throttle per engine) and other controls (eg starting and extinguishing of engines, control of air brakes, flaps, display selection of circuits to be controlled and radio navigation frequencies, etc.), while the upper panel can group circuit management controls (hydraulic, electrical, ventilation, fuel, defrost and anti-icing, lighting, etc.).

The actuators are materialized by buttons (monostable and bistable push buttons, multi-position rotators, levers, bistable switches, encoders etc.) and levers (thrust of the throttle, brake speed lever, etc.) acting in continuous or discontinuous variation to activate dedicated functions. These knobs and joysticks reproduce the real actuators while preserving the external parts to satisfy the visual and haptic aspect of human-machine interaction ergonomics.

These external parts activate, under each actuator, complex internal mechanisms and voluminous, mechanical or electromechanical, for the equipment of the aircraft in the actual cockpits. These internal mechanisms are also present in the simulators to preserve the realism of the manipulation of the external parts.

In simulators, the images displayed on the control screens come from data libraries managed by a central unit digital processing which receives the instructions provided by the commands and modifies the images of the control screens accordingly.

STATE OF THE ART

Realistic simulators are complex, heavy and bulky. In order to simplify the human-machine interface of three-dimensional ergonomics (3D) of these simulators, two-dimensional (2D) simulators using touch screens to visualize the controls and the control screens have been developed. The touch screens of these 2D simulators directly translate the contacts exerted on the image of the controls by variations in the data supplied to the control screens, which simplifies and reduces in size and weight the 3D simulators.

However, this approach is not satisfactory because the manipulation of 2D commands is not comparable to the perception of feeling and control of the gesture to that of 3D commands. Thus, any training or training, any training for new orders or new orders organizations can not be achieved under realistic conditions.

An evolution of this 2D approach is to use an interchangeable panel of commands superimposed on a display screen revealing the image of the control screens. This approach is particularly illustrated by US patent document 2010/266992. Such interchangeable panels make it possible to adapt to the cockpits of different aircraft or to new cockpits. However, the problematic complexity, heaviness and size of the simulators is not resolved because the internal part of the controls is simply remote, in the case of interchangeable panels, to allow the superposition of these panels to the display screens.

Moreover, there are also physical keyboards superimposed on virtual keyboards touch screens to optimize the touch or precision of the input. The 3D manipulation of the keyboard keys is thus recreated from a 2D virtual keyboard. Such keyboards are described, for example, in US Pat. No. 8,206,447 or US Pat. No. 8,558,796. solution is based on the substitution of a direct pressure on a location of the virtual keyboard by a pressure exerted via a dedicated key of the physical keyboard. Such correspondence between physical and virtual keyboards is incompatible with the use of aircraft cockpit controls which are designed to move more elaborately than a single contact in order to perform various actions.

STATEMENT OF THE INVENTION

The invention aims to solve the problems mentioned above, namely the implementation of less complex terminals, less heavy and less bulky, while providing a realistic 3D ergonomics for the human-machine interface. To this end, the present invention proposes to develop contact configurations of physical controls on touch screens capable of developing adjustment data or modification of a given display.

More specifically, the present invention relates to a method of interfacing between dedicated interactive organs and a touch screen with multipoint technology and / or multitouch comprising a touch screen, a display screen and a digital processing unit dedicated to visualization control. Each support of an interactive member makes contact on the touch screen which then generates contact location signals. These location signals are then transmitted to the digital processing unit which then produces, by a predetermined correlation between each location signal of each interactive device and a parameterization adapted from a predetermined display to which said interactive device is dedicated, data of backlighting of at least one interactive device by the display screen of the touch screen, setting and / or modification of the display parameters according to the location and path of the contact on a selected display screen between the display screen of the touch screen and a display screen of another touch screen.

According to advantageous features, the method according to the invention provides the following implementations:

the trajectory of the contact of each interactive element on the touchscreen may be punctiform, at least partially linear, circular, discontinuous, dotted lines and / or dots according to the movement given to the interactive organ;

- The interactive organs are backlit by a display screen associated with the touch screen, and are backlit when activated, thereby informing the user of the activated state of said bodies;

- The preset display can be viewed on a screen selected between a display screen associated with the touch screen interface with the interaction organs and the display screen of another screen. This other screen can be touch or non-touch.

The invention also relates to a control panel comprising a keyboard equipped with interactive organs to form a plastron and a touch screen with multipoint technology and / or multitouches comprising a touch screen, a display screen and a display unit. digital processing dedicated to visualization control. The display screen is chosen between a display screen interfacing with the interactive organs and the display screen of another touch screen, the front plate and the touch screen being interfaced and the backplate backlit according to the defined method above. Advantageously, the electrical conductivity of the touch screen is exploited by a technology chosen between capacitive, resistive and inductive. Alternatively non-conductive technologies (eg infrared or ultrasound) can be used. In addition, the interactive organs push button type can be mounted on an insulating elastic plate to stabilize them and exert on them a restoring force. Alternatively, the control panel may incorporate a flexible membrane integral with the front plate and which has, in the presence of each push button-type interactive member, a convex dome through which a hole at the highest point of the dome passes. In addition, antivibration means can be mounted on the control panel.

The invention also relates to a control terminal and / or control comprising at least one control panel as defined above. In particular, an aircraft flight simulator comprising cockpit panels of an aircraft of the type defined above and located in front of, above and beside the operators. In this flight simulator, at least one of these panels integrates at least one control panel defined above. In addition, the backlighting, adjustment and / or modification data from the digital processing unit of the (each) control panel is transmitted to a digital central processing unit which translates this backlighting data. , adjusting and / or modifying the video adaptation signals of the display parameters of at least one control screen of at least one panel and transmits these signals to the relevant screens.

A multi-control display unit called MCDU 10, is shown in a top view and in section in FIGS. 1 and 2. The MCDU units 10 are located at the front of the tower 530 (lower panel) of a flight simulator 500 (see Figure 7).

This unit MCDU 10 comprises a keyboard 2 of dedicated interactive organs 20 arranged in a frame 3 of plastic material. The keyboard 2 and the chassis 3 forms a front plate 30 which rests on the capacitive touch screen 4 of a liquid crystal display screen 13, the touch screen 4 and the display screen 13 forming the base of a touch screen 1 . The frame 3 is fixed on its periphery to the touch screen 4. Lateral advances 2L of the plastron 30 without an interactive member are also illustrated. Advantageously, the plastron 30 is locally backlit by LEDs integrated in the display screen 13 or by other technologies (for example organic LED or OLED), these light sources being managed by the shapes and colors displayed in FIG. the screen.

The dedicated interactive organs 20 are here push buttons that act by point contact on the capacitive touch screen 4 according to an interfacing controlled by the digital processing unit 100 of the touch screen 1. The MCDU unit 10 constituted by the plastron 30 and the touch screen 13 thus forms a control panel according to the invention, operating according to the interfacing method of the invention (see FIG.

In particular, each interactive device once activated is backlit by a transmission of LED ignition signals located under this body initiated by the digital processing unit 100. Such a backlight informs the user that the state of the organ is activated. Alternatively, the ignition signals illuminate all the LEDs under the plastron 30 which is then illuminated overall, or the ignition signals illuminate only the outline of all the interactive organs or the contour of the only activated members.

Advantageously, the digital processing unit adapts the light intensity and the other light parameters (type of color, flashing lighting with a constant or variable period, etc.) of these backlights according to the organ concerned. and / or conditions of use, especially in night / day conditions. These back-lights make it possible to restore an optimized human / machine interface (HMI) with regard to the visual aspect, which makes it possible to restore a faithful IHM of a pilot cockpit of an aircraft, in the aircraft flight simulator application described below, or a command post or a flight deck in general.

In order to further improve the realism, the digital processing unit 100 controls sound accessories adapted to control or control situations in connection with the activation of organs corresponding to simulated flight phases during a training.

Each push button 20 is made of electrically conductive plastic material or, alternatively, covered with a conductive paint film to make electrical contact with the capacitive touch screen 4. Alternatively, the buttons - or bodies generally - can be machined aluminum.

A silicone plate 8 is mounted on a base 1 1 formed in the frame 3 to perform a triple function: maintain the snaps 20 in their housing defined in the frame 3, electrically isolate the buttons 20 between them and exercise a elastic restoring force on the button when supported by the operator. Alternatively the plate 8 may be a sheet of polypropylene, PVC or any other flexible plastic material.

The capacitive touch screen 4 benefits from multipoint or multitouch technology depending on the type of organs - static or dynamic - that the keyboard accommodates. In the case of a keyboard equipped only with pushbuttons 20, such as the keyboard 2, static multipoint technology is sufficient. The touch screen 4 incorporates an electrically charged 4G grid on its outer face 4F.

During a contact by the support of a push button 20, the accumulated charges on the slab 3 are transferred to the push button 20, which creates a load deficit. The support exerted is localized by the conversion of the charge deficit into a location coordinate signal on the gate 4G which is transmitted to the digital processing unit 100. This unit 100 translates the received location signal - in connection with d other locating signals from other interactive devices - in tuning / modification data and transmitting video signals adapted to the touch screen 1 of the corresponding MCDU unit (see Figure 6). For example, the data can be used to calculate time estimates to derive arrival times, take-off and landing speeds, and so on.

Referring to the enlarged view in partial section of Figures 3a and

3b, a pushbutton 20 '- equivalent to the pushbutton 20 but in a slightly different conformation - is illustrated in a frame 3' of plastron 30 'of a control panel 301 according to the invention, respectively before and after its support on the capacitive touch screen 4. In addition to the push button 20 'in a housing 9 of the frame 3', these figures show a flexible membrane 5 - for example made of silicone or polypropylene - secured to the frame 3 'facing a non-slip insulating film 6 integral with the touch screen 4, the membrane 5 and the film 6 extending between the frame 3 and the slab 4. In this version, the frame 3 'does not include a silicone plate because of the presence of the flexible membrane 5, the simplified configuration of the button 20 'and the housing guide structure 9.

Before support (Figure 3a), the flexible membrane 5 has a convex dome 51 with respect to the push button 20. This dome 51 is crossed at its center or 5c peak by a small diameter orifice 52 relative to that of the section underlying the dome 5. The faces 5F of the dome 51 are advantageously covered with a conductive silver deposit 52.

Furthermore, the non-slip insulating film 6 extends over the capacitive touch screen 4 and under the flexible membrane 5. This non-slip insulating film 6 has an opening 61 of diameter slightly greater than the section underlying the dome. 51.

Following the support of the operator on the button 20 'by its index D1 (Figure 3b), it appears that an advanced end 2a of the button 20' exerts sufficient pressure for the dome 51 to come "s "crush" against capacitive touch screen 4 making a contact 1 c. The button 20 'being electrically conductive, the charges accumulated on the slab 4 are transferred to the push button 20' via the orifice 52 of the flexible membrane 5, then discharged by the finger D1 to form a closed circuit C1. Slab 4 acquires a signal "S" which is translated in contact location data 1 c by the processing unit 100 (see FIGS. 2 and 6). By combining with other location data, adaptation video signals are transmitted to control or control screens of a flight simulator (see Figures 6 and 7).

Other dedicated organs - static or dynamic - are also adapted to provide contact points forming configurations - respectively point or continuous - identified on the capacitive touch screen 4. In the case of using dynamic organs, the associated touch screen incorporates multitouch technology that allows multiple simultaneous dynamic contacts to be processed (whereas multipoint technology simultaneously processes only several static contacts).

For example, the partial sectional view of Figure 4a illustrates a rotary member 21 of a control panel 302 according to the invention, here in the form of a rotator. In this figure 4a, there are elements of Figure 3a adapted to the rotator 21, namely: the frame 3 ', a housing 9' formed in the frame 3 ', the capacitive touch panel 4 and the non-slip film 6.

The frame 3 'incorporates a spring loaded pusher 7 which comes into contact with a pinion with thirty-two teeth 2p which, mounted on the rotator 21, makes it possible to precisely stabilize its position during the rotation and its final position. (arrow F1). Two fingers D2, formed at the end of the rotator 21, are in contact with the capacitive touch screen 4.

The member 21 makes a permanent static contact as a rotator, to provide discontinuous or discrete data, for example radioguidance or radiocommunication frequency values. To transmit these data, the digital processing unit 100 (see FIGS. 2 and 6) retains the data corresponding to the final position of the member 21. Alternatively, a touch screen in multipoint technology is dedicated to static bodies grouped on this slab to form a control panel (as evoked with reference to Figures 1 and 2).

The member 21 can also be used to simulate an encoder in permanent dynamic contact with the capacitive touch screen 4. In this case, the touch screen is multi-layer technology so that the processing unit Digital 100 (see Figures 2 and 6) can take into account the progression of the trajectory achieved by the contact and translate this progression into variable data at successive times.

Another type of member, namely a linear actuator 22 with permanent dynamic contact, is illustrated by the sectional view of Figure 4b. Such an actuator 22 makes it possible to simulate here a gas thrust block block. It comprises two radial levers 8a and 8b rotated about a shaft 80 between three coaxial wheels 81 along the shaft 80, the rotation being here caused by the support exerted by the index D1 of the operator on the handle 8a. The other handle 8b is not maneuvered in the illustrated example.

The sectional view of Figure 4b shows the mechanism made by way of example to implement a permanent and linear dynamic contact. This mechanism consists of a steel cable 82, coming from a main crown section 8c centered on the shaft 80 and guided by a sheave 83 to an attachment point 84, this fixing point being positioned at the periphery of the wheel 81 via a spring 85 for elastic tensioning. Between the outlet of the sheave 83 and the attachment point 84, the cable 82 extends parallel to the outer face 4F of the capacitive plate 4 of the touch screen 1 (see FIG. This slab 4 benefits from multitouch technology to identify and process permanent dynamic contacts.

In addition, a rubbing finger D3 is arranged on the cable portion 82 parallel to the outer face 4F of the capacitive touch screen 4. Thus the rubbing finger D3 remains in contact with the touch screen 4 by moving linearly when the handle 8a is actuated in rotation. During this rotation (arrow F2), the excess charge flows in the closed circuit C2 formed by the index D1 of the operator via the cable 82. The slab 4 acquires signals "S" when moving linear D3 finger, these signals "S" being translated into location data by the processing unit 100 (see Figures 2 and 6). The length of the linear trajectory thus localized provides data of amplitude of the desired thrust of the gases, which will generate video signals of adaptation of the display parameters of the control screens of the panels of the flight simulator (see figures 6 and 7). Static or dynamic contact mechanisms can thus be adapted in an equivalent manner for any type of organ conventionally used in an aircraft cockpit or in a driving position of other vehicles, such as those illustrated by the front views of FIG. 5: button with indicator light 41, bistable actuator 42, multi-position switch 43, rotary switch 44, push-pull button 45, analog button 46, lever 47 and joystick 48. These adapted mechanisms perform, in a manner equivalent to those described with reference to FIGS. 4a and 4b, partially or completely linear, circular, curved, continuous or discontinuous paths, in dashed lines and / or in points.

The functional logic diagram of a flight simulator according to the invention is illustrated in FIG. 6. It involves the interfacing according to the invention between the interactive members 200 and the touch screens 1 (see FIG. control facades 300 and between these facades and panels of a flight simulator 500 (see Figure 7).

By successive pressure exerted by the operator on a control panel 300, the interactive members 200 - such as the members 20, 20 ', 21, 22, 41 to 48 described above - make point or continuous contacts 1 c on the touch screen 1 (step "A"). These contacts, electrically conductive, generate location signals "S" at the touch screen 4 which are transmitted to the digital processing unit 100 of the touch screen 1 (step "B").

Flight parameter setting data (speed, thrust, altitude, horizontality, etc.) or information modification (guidance, route, time estimates, etc.) are then calculated by the unit 100 from pre-acquired correlations between localization signals of each member 200 and variations of parameterization of the display of the relevant control screen - located in a panel of the flight simulator - and to which the organ 200 is dedicated (step "C").

These adjustment data are then transmitted to a central digital management unit 400. This central unit 400 actually collects the data of all the digital processing units 100 of all the control facades 300 (such as facades 10, 301 or 302 described above) of the simulator. When the adjustment data received by the central unit 400 are not coherent with each other (arrow "NO"), the central unit 400 transmits an error signal on the relevant control screen of the simulator 500 concerned. and the operator is invited on this screen to resume manipulations on the control facades concerned (step "D"). Otherwise ("YES" arrow), the central unit 400 coherently translates all the adjustment data received into adaptation video signals and transmits these video signals to the relevant screens, here in the control screens of the simulator 500 (step "E").

In order to show the architecture of a flight simulator of an airplane according to the invention, the flight simulator 500 comprising control facades 300 according to the invention is illustrated (without the seats) on the view in perspective of Figure 7. This simulator 500 consists of a main control panel 510 (or dashboard) capped the automatic control panel 520 (which is not involved in the simulation example described, but in other embodiments to cut, trigger or set limits to the autopilot), a longitudinal flight guidance panel 530 disposed in a lower position between the operators (the "pylon"), and an upper circuit management panel 540, above the operators.

All these panels (except the automatic control panel 520) consist of touch screens 1 (see Figure 2) 16/9 format (ratio between large and small sides), namely more precisely in this figure 7 : three control display touch screens 91a and 91c, adjacent by the short side to form the main control panel 510, three control display touch screens 93a to 93c adjacent by the long side to form the control panel; longitudinal guide (pylon) 530, and two touch screens 94a and 94b adjacent by the long side to represent the top panel 540.

Plastrons 33 to 39 form control facades 300 (see Figures 6) with the touch screens on which they are attached. Thus, on the central screen 91c of the control panel 510, a front plate 33 is fixed so as to form with the central screen 91c a control panel 300 according to the invention. The front plate 33 comprises a lever 47 serving as a landing gear input / output lever of the aircraft, and push buttons provided with lights 41 for the aircraft. automatic brake controls. The central screen 91c displays control information of the engines on the control screen 14 (power, consumption, alerts) and systems on the control screen 12 (hydraulic circuits, ventilation, etc.). The screens 91a of the control panel 510 display information on the navigation with the control screen 18 (aircraft heading, meteorology, flight path, radio navigation beacons, etc.) and a primary flight control screen. 16.

On the screen 93a of the pylon 530 placed closer to the control panel 510, two plates 34 are placed laterally to form two information entry units MCDU (number of passengers, airports of departure and arrival). , chosen path, etc.) such as the unit 10 described with reference to FIGS. 1 and 2. Moreover, on this same pylon 530, are also arranged (the reference signs of the organs mentioned below refer to FIGS. 4b and 5):

- Between the MCDU 10 units, a central plate 35 having push buttons 20 ', rotary switches 44 and selection coders 21 dedicated to the choice of the displays of the control screens 12, 14, 18 of the control panel 510;

behind the MCDU units 10, two side plates 36 provided with pushbuttons 20 and 20 ', encoders 21 and a rotary switch 44 for selecting the radio navigation and communication frequencies;

- Between the side plates 36, the thrust block throttle 22, and push buttons 20 'firing the engines;

- At the rear of the pylon 530, a front plate 37 includes levers 47 and 48 for controlling the airbrakes and flaps of wings.

When the screens 94a and 94b of the upper panel 540, they are respectively covered with central plates 38 and 39 comprising, respectively:

switches 43 serving as circuit breakers associated with the various avionic systems (air conditioning, lighting, defrosting, pressurization, etc.);

- pushbuttons 20 'for fire extinguishers for the engines and the APU (the auxiliary energy unit) and for circuit management hydraulic, fuel and electrical circuits; three-position switches 44 in connection with pushbuttons 20 'for the management of air circuits, and switches 43 for defrosting / anti-icing controls, external / internal lighting of the aircraft and start-up of the aircraft. COULD.

The invention is not limited to the embodiments described and shown. Thus, the technology used to exploit the electrical conductivity of the touch screen may be other than capacitive, for example of the resistive or inductive type, the interactive organs then being as many stylets usually adapted to this type of technology. Alternatively, touchscreens using non-conductive technologies - infrared, ultrasound, surface waves - can be used.

In addition, these touch panels can be reduced to tactile "surfaces" when the touch function is integrated directly into the display screen or is remote in another part. For example, when the touch function is implemented without the support of a display screen.

In addition, antivibration means - for example pads, plates, sleeves or equivalent absorbent material - can be mounted on the control facades to secure the holding of organs.
