Definitions
- the present invention claims the priority of French application 2101248 filed on 02.10.2021, the content of which (text, drawings and claims) is incorporated herein by reference.
- the present invention belongs to the field of haptic systems capable of receiving and processing user haptic inputs. It relates in particular, but not exclusively, to a haptic system for controlling equipment or a screen of a motor vehicle.
- haptic system is integrated into the cockpit, the central console or the door panel of a motor vehicle.
- Achievements of the prior art provide systems for remotely controlling a screen of a motor vehicle.
- a first embodiment of the prior art is a conventional “trackpad” comprising a touch-sensitive surface integrated into a central console of a motor vehicle.
- Such a “trackpad” allows you to control a screen remotely, just like a laptop trackpad or a computer mouse.
- touch surfaces are rectangular and flat.
- a second embodiment of the prior art proposes a dashboard comprising static pictograms backlit under a material fulfilling an aesthetic function.
- the pictograms are not visible but appear following a stimulus, such as the start of the vehicle or the approach of a finger of the user.
- a stimulus such as the start of the vehicle or the approach of a finger of the user.
- the first embodiment is limited in its possibilities, and what it is a flat surface, without reconfiguration or possible visual feedback.
- Touch screens may be provided to provide visual feedback in addition to capturing haptic input from a user.
- such a solution results in an additional manufacturing cost price, as well as more numerous integration constraints due to the screen.
- Another disadvantage of the touch screen is that the screen is permanently on, which induces increased power consumption and heating of the touch surface.
- the present invention improves the situation.
- a first aspect of the invention relates to a haptic system comprising:
- a stack of layers comprising at least one set of haptic sensors and a light layer, the set of haptic sensors being able to detect haptic input from a user and to generate haptic data indicating at least one position of said haptic input , and the luminous layer comprising a plurality of luminous elements;
- control device capable of receiving the position of a haptic input from the set of haptic sensors
- the set of haptic sensors is a layer of haptic sensors, the haptic sensors of the layer facing the luminous elements of the luminous layer and the control device is able to determine a luminous command as a function of the haptic data, the luminous command indicating at least one position of the luminous elements to be activated.
- the device for controlling the light layer is configured to activate one or more of the light elements of the light layer, determined according to the light command received from the control device.
- a luminous feedback from the activation of luminous elements allows the user to note the presence of the haptic system, without using a permanently lit screen.
- such a system can be dynamic, in particular when the user's haptic inputs change, the user touches several positions, changes the position of his finger, or performs a slide with his finger.
- the use of a sheet of haptic sensors as well as a plurality of luminous elements, such as LEDs for example, allows many possible configurations for the stacking of layers, in terms of shapes and surfaces. Integration under material or decorative film is thus facilitated, such a type of integration being complex in the case of a touch screen according to the embodiment of the prior art.
- the stack of layers may also comprise an outer layer, the sheet of haptic sensors being between the outer layer and the luminous layer.
- Such an outer layer makes it possible to protect the other layers of the stack and also makes it possible to make the sensors and the luminous elements more discreet, or “seamless”.
- the outer layer may comprise a textured and/or stylized material, the material being able to let through at least a part of the light rays emitted by the activated light element(s) and being able to hide the layers of the stacking near deactivated light elements.
- the haptic system is made invisible from the outside by the user, when not in use. It saves significant space, in particular when it is integrated into a motor vehicle in that it also fulfills an aesthetic function.
- the stack of layers can also comprise a mask, the mask being included between the outer layer and the sheet of haptic sensors, the mask comprising an alternation of opaque zones and zones transparent so that the light emitted by the activated luminous element(s) is filtered by said mask before reaching the outer layer.
- a mask makes it possible to increase the configuration possibilities of a luminous element.
- a mask can allow greater luminosity in the center of the layer stack, so as to indicate the position of the haptic system to the user, which is particularly useful when the haptic system comprises an outer layer which conceals the other layers.
- control device may also be capable of generating a command as a function of the haptic data and of transmitting said command to an entity external to the haptic system.
- the haptic system according to the invention also performs the function of remote control, without requiring a screen, with high input precision for the user and very high configurability in terms of haptic inputs.
- the external entity can be a screen and/or equipment of a motor vehicle.
- the haptic system can thus perform the function of a trackpad or can control equipment such as air conditioning for example.
- the light control can control the activation of light elements located at less than a first predetermined distance from the position of the haptic input, at a first light intensity.
- the accuracy associated with the user's haptic input is improved in that the user can identify the position of their finger that has been sensed.
- the light control can control the activation of light elements located between the first distance and a second distance from the position of the haptic input at a second light intensity, the second distance being greater than the first distance and the second light intensity being less than the first light intensity.
- control device is configured to decrease the luminous intensity of an activated luminous element over time, until said luminous element is extinguished.
- the power consumption of the haptic system is reduced and the precision associated with the haptic input is improved since the user has a light feedback indicating also the duration between the instant of the haptic input and a current instant.
- the sheet of haptic sensors may be able to transmit in real time haptic data indicating the position of the user's finger to the control device, and when the haptic input is a sliding of the finger of the user between a first position and a second position, the control device is able to generate in real time, on reception of the haptic data, a light command and to transmit said light command to the device for controlling the light layer.
- the luminous feedback is dynamic, which allows varied haptic inputs, in particular of the sliding type, with high precision insofar as the user has direct and real-time feedback on the path taken by his finger.

- the stack of layers 100 can comprise an outer layer 101, accessible to the touch by a user.
- the outer layer can be a film or a layer of material, thicker than a film. No restriction is attached to the material of the layer outside 101, the only condition being that it is illuminated by a luminous element in contact with it, at least part of the light beam passes through the outer layer 101, even attenuated.
- the outer layer 101 is therefore not completely opaque: it makes it possible on the one hand to hide the other layers of the stack 100 and on the other hand to be backlit as detailed below.
- the outer layer 101 can in particular fulfill an aesthetic function.
- the outer layer can be textured and/or stylized. It can have a wood or marble effect, for example.

- the spacings between the LEDs can be regular and correspond to a spacing 106, as illustrated in FIG. 1.
- the spacing between the LEDs of the matrix can vary.
- a layer is any planar structure extending primarily in two dimensions, although a layer can be deformed three-dimensionally. Such a layer can be more or less flexible or rigid.
- the layers may not be flat, but wavy, or in any three-dimensional shape, although they extend mainly in two dimensions, called principal dimensions.
- the layers can also be flexible and take the form of a rigid support located under the layer 104 and not shown in Figure 1.
- the two main directions can correspond to two axes and each position on the surface of a layer can thus be identified by two coordinates X and Y, as will be detailed below.
- the thickness of the layers of the stack 100 which can be films and/or layers of thicker material.
- the thickness is significantly less than the two main dimensions of the layer.
- the haptic system 10 may further comprise a control device 110, able to determine X and Y coordinates in real time corresponding to the position of the user's finger on the haptic sensor 100, when a haptic input is detected by the haptic sensor 103. Such data can be received from a microcontroller of the haptic sensor 103, not shown in FIG. 1.

- the light controls can in particular indicate positions or indexes of the light elements 105 to be activated, the light intensities and/or the respective colorimetries.
- control device 110 can further generate screen commands based on the data received from the haptic sensor 103.
- Screen commands can be transmitted to a screen 120, and the screen 120 is configured to modify a display based on the received screen commands. No restriction is attached to the format of the screen commands or to the modification induced by the reception of the screen commands by the screen 120.
- the haptic system 10 can allow the screen 120 to be controlled remotely.
- the control device 110 can also generate vehicle commands on the basis of the data received from the haptic sensor 103.

- the vehicle commands can be equipment commands for controlling any equipment, including equipment not included in a motor vehicle.
- the haptic system 10 can make it possible to control elements of the vehicle, when the haptic system 10 is installed in a vehicle.
- FIG. 2 presents the steps of a method for generating a command by the control device 110, according to one embodiment of the invention.
- the control device 110 receives data from the haptic sensor 103, or from the microcontroller of the haptic sensor 103. No restriction is attached to the format of such data.
- the control device 110 processes the haptic data received.

- the control device 110 can comprise a second interface capable of transmitting light commands to the light layer 104.
- the control device 110 may include a third interface capable of transmitting screen commands to the screen 120.
- the control device 110 may comprise a fourth interface capable of transmitting vehicle commands to the vehicle control device 140.
- Figure 4 shows an example of light rendering of a haptic system according to the invention.
- the user sweeps the outer layer 101 with his finger, either after pressure, or after a simple contact in a first position 402.1.
- the haptic sensor 103 detects the user input, namely the trajectory of the user's finger between the two positions 402.1 and 402.2.
- the captured haptic data is transmitted, for example in the form of coordinates, following user input, or in real time, to the control device 110.
- the control device 110 In response to this haptic data, the control device 110 generates commands luminous indicating luminous elements 105 or groups of luminous elements 105 lying on the trajectory of the detected user's finger.
- the light commands can be transmitted at the end of the haptic input, or, preferably, in real time upon receipt and processing of the haptic data itself received in real time.
- An “evanescent" light effect can consist in reducing the light intensity of the light elements for a certain time after their activation, or continuously from activation.
- the current position 402.2 of the user's finger is signaled with greater luminosity than the rest of the trajectory of the finger, in particular the initial position 402.1.
- Such an effect advantageously makes it possible to improve the precision of the user's haptic input and to reduce the energy consumption of the haptic system 10.
- a light trajectory 401 is visible from the outside, the light trajectory 401 following the trajectory of the user's finger.
- the light trajectory 401 has a honeycomb pattern, corresponding to the optional mask 102 described previously.
- Figure 4 shows an example of a “slide” type haptic input, for illustrative purposes only.
- Figures 5a and 5b illustrate masks 102 according to several embodiments of the invention.
- the mask 102 is optional.
- the mask 102 allows the production of luminous patterns in return for the user's haptic contact.
- FIG. 5a for example illustrates a mask 102 according to a first pattern.
- FIG. 5b illustrates a mask 102 according to a second pattern, according to which the transparent zones are denser in the center of the mask 102 than at the ends of the mask 102.
- the mask 102 notably has a density gradient of the transparent zones as the distance in the center of the mask 102 increases.
- the mask 102 is shown in rectangular form. However, no restriction is attached to the shape of the mask 102.
- Figures 6a shows a front view of a haptic system according to one embodiment of the invention. According to the embodiment of Figure 6a, a luminous display 601 is produced by the haptic system 10.
- the luminous display 601 is circular, with two concentric circles of different luminosity, the smaller circle having a higher luminosity than the band of the larger circle which surrounds it.
- Such a display is given for illustrative purposes only, other forms of display may be provided to welcome or leave the user.
- the stack 100 is of rectangular format. However, the invention covers any other form of stack 100.
- the illuminated display 601 may be produced without detecting haptic input from the user, but to indicate the presence of the haptic system, which otherwise is invisible due to the outer layer 101.
- the luminous display 601 can be produced when the vehicle is started and/or when it is switched off, either as a welcome or goodbye message, or in order to signal the presence of the haptic system 10 only.
- Figure 6b shows a front view of a haptic system according to one embodiment of the invention.
- the embodiment of Figure 6b includes the circular light display 601 of Figure 6a.
- a luminous display 601 can be a greeting or a goodbye message.
- a haptic input is detected in addition to the greeting message.
- controller 110 In response to haptic input detected by haptic sensor 103, controller 110 generates a light command sent to light layer 104, which produces light feedback 602 for the user.
- the luminous feedback 602 thus makes it possible to indicate to the user that the haptic system 10 is interactive and can make it possible to control an external entity such as the screen 120 or equipment of the vehicle via the vehicle control device 140.
- FIG. 7a presents a first light feedback 701 associated with a first haptic input, according to one embodiment of the invention.
- the first haptic input corresponds to an input which can include:
- the first luminous feedback 701 of FIG. 7a only indicates the position of the maintained press; - a long press, lasting longer than a long threshold.
- the long threshold can be 3 seconds;
- the haptic system can: optionally activate a “wake-up effect”, such as the luminous display 601 presented above, if the haptic system was on standby;
- the luminous elements 105 positioned in a circle or two concentric circles, at the place where the haptic input is captured, in accordance with the first luminous feedback 701 of figure 7a.
- concentric circles of radii equal to 1 and 2 cm respectively can be displayed at the X and Y coordinates determined by the haptic sensor 103 or by the control device 110.
- the light feedback can disappear one second after the haptic input, or after the end of the maintained press, or one second after the first 350 milliseconds of maintained press, therefore at the end of the threshold duration.
- the luminous return can gradually lose brightness until the extinction of the luminous elements 105.
- the first luminous feedback 701 is preferentially displayed for haptic inputs of the touch or localized pressing type.
- the haptic system can issue screen commands and vehicle commands corresponding to the detected haptic input.
- FIG. 7b presents a second luminous feedback 702 associated with a second haptic input, according to an embodiment of the invention.
- the second haptic input is a sliding of the user's finger on the outer layer between a starting position 703 and an arrival position 704.
- the second luminous feedback 702 can correspond to the trajectory traveled by the finger between the two positions 703 and 704.
- the thickness of the line corresponding to the trajectory can be predetermined. For example, it may correspond to the switching on of the light elements 105 located more or less D millimeters away, for example 5 millimeters, on either side of each detected position of the finger on the trajectory.
- the neighboring luminous elements 105 can be lit for a predetermined duration, such as one second for example.
- the luminosity of the luminous elements 105 neighboring a given position of the trajectory can decrease progressively between the moment of ignition and the moment of extinction, so as to create a residual effect. This facilitates the capture of the haptic input by the user and improves its accuracy.
- Figure 7c shows a third light feedback associated with a third haptic input according to one embodiment of the invention.
- the second haptic input corresponds to a pinch or a separation between two fingers of the user, for example to zoom in or zoom out on the screen 120.
- the light feedback can correspond to two circles 705 and 706, respectively centered around positions of each finger, and having a fixed radius, of the order of one centimeter, for example equal to one centimeter.
- the luminous elements 105 located one centimeter or less than 1cm from the detected position of each finger are activated by the control device 110.
- Each circle can follow the movement of each finger, and disappear when the fingers are no longer in contact with the outer layer 101.
- FIG. 8 presents a haptic sensor 103 and a set of luminous elements 105, of a haptic system 10 according to one embodiment of the invention, in the case of a haptic input of the touch, pressure or point approach type.
- the outer layer 101 is not represented in order to better understand the operation of the luminous layer and of the haptic sensor.
- the haptic sensor determines such a pair of coordinates and transmits it to the control device 110 discussed above.
- the control device 110 can generate a light command and transmits the light command to the driver device 130 of the luminous layer comprising the luminous elements 105.
- the control device 130 activates some of the luminous elements 105, determined from the luminous command, in order to produce a luminous return 803.
- the luminous return 803 can be composed of two concentric circles 804 and 805 presenting distinct luminosities.
- the luminous elements located less than a first distance from the position corresponding to the coordinates 801 and 802, therefore positioned in the first circle 804 are controlled to have a first luminosity
- the luminous elements located between the first distance and a second distance, therefore positioned in the second circle 805 are controlled to have a second luminosity, lower than the first luminosity.
- light elements 105 located in the first circle 804 are controlled to illuminate at 100% of their nominal intensity, while light elements located in the second circle 805, but outside the first circle 804, are controlled not to light. illuminate only at a fraction of their nominal intensity, for example 75% of their nominal intensity.
- Such luminous feedback 803 makes it possible to improve the precision of the haptic input by the user.
- FIG. 9 presents a haptic sensor 103 and a set of luminous elements 105 of a haptic system 10 according to one embodiment of the invention, in the case of a haptic input of the sliding type, or “slide” in English .
- the user has previously touched the haptic system 10 at a first position, corresponding to first coordinates 901 and 902 detected by the layer 103, then has performed a slide to a second position, corresponding to second coordinates 903 and 904.
- control device 110 can generate a light command and transmits the light command to the driver device 130 of the luminous layer 104 comprising the luminous elements 105.
- a succession of luminous commands can thus be transmitted for each intermediate position of the trajectory between the first position and the second position.
- control device 130 Upon receipt of a light command, the control device 130 activates some of the light elements 105, determined from the light command, in order to produce a haptic feedback 910.
- the luminosity of a luminous element 105 can decrease with time after their activation, following the passage of the finger of the user in a vicinity of the luminous element 105.
- the luminous intensity of the luminous element 105 is maximum between its activation at a time t0 and the time t0+d1, d1 being a predefined duration.
- d1 can be of the order of a second, for example equal to 0.5 seconds.
- the luminous intensity of luminous element 105 may be less than the maximum intensity, for example equal to an intensity 11 equal to 75% of the maximum luminous intensity, d2 being a duration greater than d1.
- the duration d2 can be of the order of one second, for example equal to one second.
- the luminous intensity of the luminous element 105 can be less than the intensity I1, for example equal to an intensity I2 equal to 50% of the maximum luminous intensity.
- the luminous element 105 can be extinguished after a duration d3, greater than d2.
- the duration d3 can for example be greater than or equal to 2 seconds.
- the luminous elements 105 located near the second position have therefore been activated more recently than the luminous elements 105 located near the first position, which explains the intensity gradient of the luminous return 910 of FIG. 9.
- a gradient can be continuous as in figure 9 or can correspond to intensity levels as described above, such as: - A first set of light elements 911, which have been activated between t1-d1 and t, with maximum intensity;
