[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] According to a first aspect of this application, embodiments of this application provide a touch feedback method.

[0048] Please see Figure 1 , Figure 1 This is a flowchart of a touch feedback method provided in an embodiment of this application. The touch feedback method may include the following step S100:

[0049] Step S100: In response to the target touch operation, transmit a temperature haptic feedback signal to the location of the target touch operation.

[0050] This application does not limit the target object of the target touch operation. In some embodiments, the target object of the target touch operation may be a display screen, thus the target touch operation is a touch operation on the display screen. In some embodiments, the target object of the target touch operation may be a physical component in the device, thus the target touch operation is a touch operation on a physical component in the device; for example, the target touch device may be a touch operation on a physical button in a smart home device, smart medical device, industrial equipment, etc. In some embodiments, the target object of the target touch operation may also be any object in the operating space, thus the target touch operation is a touch operation on any object in the operating space; for example, a user can perform a target touch operation in any direction within an operating space, and the target touch operation can be performed arbitrarily in the air without the aid of any physical object.

[0051] In response to a target touch operation, a temperature-sensitive haptic feedback signal is emitted towards the location of the target touch operation. The location of the target touch operation can be the current operation position or a predicted operation position at the next moment. The location of the target touch operation can be a single point or a region of a certain area. The temperature-sensitive haptic feedback signal is used to change the surface temperature of the target operation area, for example, by increasing or decreasing it. The target operation area refers to the main body of the operation located at the target touch operation location, such as a finger, palm, or nose tip. For example, if the user is the main body of the target touch operation and performs the target touch operation with their finger, then the target operation area is the finger performing the target touch operation. The temperature-sensitive haptic feedback signal possesses target energy; when the temperature-sensitive haptic feedback signal comes into contact with the target operation area, the target energy of the temperature-sensitive haptic feedback signal can be converted into target heat energy, thereby changing the surface temperature of the target operation area.

[0052] In summary, the touch feedback method provided in this application, in response to a target touch operation, emits a temperature-sensitive tactile feedback signal to the location of the target touch operation. Since the temperature-sensitive tactile feedback signal possesses energy, when it comes into contact with the operating subject, the energy of the temperature-sensitive tactile feedback signal is converted into heat energy, thereby changing the surface temperature of the operating subject. This application uses a temperature-sensitive tactile feedback signal as the tactile feedback signal for touch operations, providing users with realistic touch feedback at the temperature change level, enhancing the user's touch experience, and enriching the interaction methods.

[0053] In some embodiments, the target touch operation is a touch operation on the display screen. The display screen can refer to the display screen presented on the display panel, or it can refer to a floating display screen. A floating display screen is a user-visible display screen generated in air without a medium. Floating display screens are based on floating display technology, which can reconstruct the light field using negative refractive index flat lens, etc., to present a floating display screen. For a description of the display principle of floating display screens, please refer to the following embodiments, which will not be elaborated here.

[0054] Users can perform touch operations, such as tapping, swiping, and long-pressing, within the touch area of ​​the display screen. The touch area can overlap with the display area, such as being the same area or partially overlapping, or it can be a different area. This embodiment does not limit this, but typically the touch area can overlap with the display area. When a user performs a touch operation within the touch area of ​​the display screen, the touch feedback system receives the user's touch operation. In response to a target touch operation on the display screen, the touch feedback system emits a temperature-sensitive haptic feedback signal to the location of the target touch operation.

[0055] The target touch operation responded to by the touch feedback system can refer to a valid touch operation on the display screen, or it can refer to any touch operation on the display screen; this application embodiment does not limit this. In some embodiments, a target touch operation is considered valid when it meets preset conditions, such as the operation duration of the target touch operation reaching a preset duration, the operation type of the target touch operation being a preset type, or the operation position of the target touch operation being a preset position. For further descriptions regarding whether a target touch operation is valid, please refer to the following embodiments, which will not be repeated here.

[0056] The location of the target touch operation can refer to the current operation location of the target touch operation. In this embodiment, the touch feedback system, in response to a target touch operation on the display screen, transmits a temperature tactile feedback signal to the location of the target touch operation.

[0057] In some embodiments, to avoid affecting the display effect, the temperature haptic feedback signal is an invisible signal, such as an infrared beam or microwave signal. However, this does not constitute a limitation of this application. In practical applications, a visible temperature haptic feedback signal can also be set according to requirements. In some embodiments, the temperature haptic feedback signal can be one or more beams of light. For further description of the temperature haptic feedback signal, please refer to the following embodiments, which will not be repeated here.

[0058] In some embodiments, to identify user touch operations, the above-mentioned touch feedback method may further include emitting a touch recognition beam. In some embodiments, to avoid affecting the display effect of the display screen, the touch recognition beam is an invisible beam, such as an infrared beam, but this does not constitute a limitation of this application. In practical applications, a visible temperature tactile feedback signal can also be set according to requirements. The touch recognition beam covers the touch area. In some embodiments, the touch recognition beam may be located on the same plane as the display screen. In some embodiments, the touch recognition beam may be multiple beams to cover the touch area of ​​the display screen. In some embodiments, the touch recognition beam may be continuously emitted, for example, starting when the display screen begins to display and continuously emitting the touch recognition beam until the display screen ends; or, the touch recognition beam may be emitted within a target time period, for example, continuously emitting the touch recognition beam when the touch interaction function is presented on the display screen, and not emitting the touch recognition beam when the video playback function is presented on the display screen and the touch interaction function is locked.

[0059] Based on the emission of the touch recognition beam, step S100 may further include: in response to receiving the target reflected beam, emitting a temperature tactile feedback signal towards the location of the target touch operation. When the user performs a target touch operation, the touch recognition beam, upon contacting the target operation part (such as the user's finger), is reflected back by the target operation part, thus allowing the touch feedback system to receive the target reflected beam. If the target reflected beam is received, the target touch operation is received. The touch reflection beam of the touch recognition beam includes the target reflected beam, and the optical path of the target reflected beam is within a preset range. In some embodiments, the preset range can be determined in advance by performing adjustments or other operations in conjunction with the touch area of ​​the display screen. When the optical path of a certain touch reflected beam falls within the preset range, that touch reflected beam is the target reflected beam, thereby indicating that the user's target touch operation has been received in the touch area of ​​the display screen. For further descriptions of the touch recognition beam, touch reflected beam, target reflected beam, etc., please refer to the following embodiments, which will not be elaborated upon here.

[0060] In summary, the touch feedback method provided in this application, in response to a target touch operation on the display screen, emits a temperature-sensitive tactile feedback signal towards the location of the target touch operation. Since the temperature-sensitive tactile feedback signal possesses energy, when it comes into contact with the operating subject, the energy of the temperature-sensitive tactile feedback signal is converted into heat energy, thereby changing the surface temperature of the operating subject. This application uses a temperature-sensitive tactile feedback signal as the tactile feedback signal for touch operations, providing users with realistic touch feedback at the temperature change level, enhancing the user's touch experience, and enriching the interaction methods of display technology.

[0061] In some embodiments, the method further includes: in response to a target touch operation on the display screen, if the target touch operation is valid, displaying a screen operation corresponding to the target touch operation on the display screen.

[0062] A valid target touch operation can mean that the target touch operation meets preset conditions, such as the operation duration reaching a preset duration, the operation type being a preset type, or the operation position being a preset position. Typically, different target touch operations correspond to different screen operations. For example, if the target touch operation is clicking a video play button, the corresponding screen operation is playing the corresponding video on the display screen.

[0063] In some embodiments, step S100 may include: in response to a target touch operation on the display screen, if the target touch operation matches a preset touch operation, displaying a screen operation corresponding to the target touch operation on the display screen.

[0064] Preset touch operations can be freely configured according to needs, for example, Figure 2 As shown, the preset touch operations include, but are not limited to, swiping up, swiping down, swiping left, swiping right, tapping, and long-pressing. Among these, Figure 2 The sliding directions shown are based on the up, down, left, and right directions of the displayed screen. If the target touch operation matches a preset touch operation, for example, if the target touch operation is... Figure 2 If any of the preset touch operations shown are selected, the target touch operation will be valid, and the screen operation corresponding to the target touch operation will be displayed on the screen.

[0065] In some embodiments, step S100 may include the following steps S111 to S112:

[0066] Step S111: In response to a target touch operation on the display screen, acquire the target trajectory data of the target touch operation;

[0067] Step S112: If the target trajectory data matches the operation trajectory data of the preset touch operation, then the screen operation corresponding to the target touch operation is displayed on the display screen.

[0068] Upon receiving a target touch operation, the target trajectory data of the target touch operation can be acquired. This target trajectory data is the operation trajectory of the target touch operation. If the target trajectory data matches the operation trajectory data of a preset touch operation, for example, if the operation trajectory data of the preset touch operation includes the target trajectory data, then the target touch operation is valid, and the screen operation corresponding to the target touch operation is displayed on the display screen. The trajectory data includes, but is not limited to, data such as position and time.

[0069] In some embodiments, to facilitate the identification of the target touch operation and the acquisition of the target touch operation trajectory, the touch feedback method further includes emitting a touch recognition beam. In some embodiments, the touch recognition beam and the display screen are located on the same plane. The touch recognition beam covers the touch area, and the touch area may or may not overlap with the display area where the display screen is located.

[0070] Based on the emission of the touch recognition beam, the above step S111 may include: in response to receiving the target reflected beam, determining the target trajectory data of the target touch operation according to the reception time of the target reflected beam, the emission time of the target recognition beam corresponding to the target reflected beam, and the emission position of the target recognition beam; wherein the touch reflected beam of the touch recognition beam includes the target reflected beam, and the optical path of the target reflected beam is within a preset range.

[0071] By analyzing the reception time of the target reflected beam and the emission time of the corresponding target recognition beam, the propagation duration of the target reflected beam can be determined. Based on this propagation duration and the speed of light, the optical path of the target reflected beam can be determined. Finally, by analyzing the optical path and the emission position of the target recognition beam, the current operation position of the target touch operation can be determined. Continuously acquiring the current operation position during the target touch operation allows for the determination of the target trajectory data.

[0072] For example, such as Figure 3 As shown, the touch recognition beam 110 emitted by the touch feedback system can be located in the same plane as the display screen 200, that is, the touch area and the display area can be the same. When the user inputs a target touch operation by placing a finger in the display area where the display screen 200 is located, the target recognition beam in the touch recognition beam 110 comes into contact with the user's finger and is reflected, and the optical path of the target reflection beam of the target recognition beam is within a preset range.

[0073] The preset range can be determined based on the touch area of ​​the display screen 200. In some embodiments, such as Figure 3 As shown, taking the touch recognition beam 110 emitted from the bottom of the display screen 200 as an example, if the touch recognition beam 110 reflected at the bottom of the display screen 200 forms a first reflected beam, and the touch recognition beam 110 reflected at the top of the display screen 200 forms a second reflected beam, then the range between the optical path lengths of the first and second reflected beams is a preset range. When the target touch operation is located in the display area / touch area of ​​the display screen 200, the optical path length of the target reflected beam formed by reflecting through the target operation portion of the target touch operation is within the preset range.

[0074] In some embodiments, to improve the accuracy of touch recognition, the emission position range of the touch recognition beam is matched with the touch area of ​​the display screen. For example, as Figure 3 As shown, the touch area is the same as the display area. If the touch recognition beam 110 is emitted from the bottom of the display screen 200, the emission position range of the touch recognition beam 110 is equal to the length of the bottom of the display screen 200. Of course, the touch recognition beam can also be emitted from the top, left, or right side of the display screen. In addition, besides rectangular display areas, the display screen can also have display areas of other shapes such as circles. The touch recognition beam can at least cover the display area of ​​the display screen. For example, if the display screen is a circular display area, the emission position range of the touch recognition beam can be greater than or equal to the diameter of the circular display area.

[0075] In addition, such as Figure 3 As shown, the touch feedback system can obtain the reception time t2 of the target reflected beam, the emission time t1 of the target recognition beam, and the speed of light v = 3.0 × 10⁻⁶. 8 If the target reflected beam's speed is m / s, then the optical path y1 = v × (t1 - t2); furthermore, by combining the emission position x1 of the target recognition beam, the current operation position of the target touch operation can be determined as (x1, y1). During the target touch operation, by continuously recognizing the current operation position in this way, the operation trajectory of the target touch operation can be determined. For example, Figure 3 As shown, the touch recognition beam 110 is emitted from the bottom of the display screen 200, and the operation position of the target touch operation is based on a coordinate system established with the lower left corner of the display screen as the origin, the bottom of the display screen as the x-axis, and the left side of the display screen as the y-axis.

[0076] In summary, the touch feedback method provided in this application, in response to a target touch operation on the display screen, determines whether the target touch operation is valid. If valid, it displays the screen operation corresponding to the target touch operation, thus avoiding accidental touches by the user. Furthermore, this application combines a touch recognition beam to identify the user's target touch operation and its target operation trajectory, ensuring timely and accurate identification of the user's touch operation.

[0077] In some embodiments, step S100 may include the following steps S121 to S122:

[0078] Step S121: In response to the target touch operation, determine the target feedback temperature;

[0079] Step S122: Based on the target feedback temperature, transmit a temperature tactile feedback signal to the target touch operation location.

[0080] Target feedback temperature refers to the temperature of the target operating part that needs to be fed back to the target touch operation, and the temperature to which the surface temperature of the target operating part needs to be changed, such as the temperature to which it is increased or decreased.

[0081] In some embodiments, step S121 may include the following steps S1211 to S1212:

[0082] Step S1211: In response to the target touch operation, obtain the initial surface temperature of the target operation area;

[0083] Step S1212: Determine the target feedback temperature based on the initial surface temperature.

[0084] This application embodiment can determine the target feedback temperature based on the initial surface temperature of the target operating portion of the target touch operation. The target operating portion refers to the operating body portion located at the target touch operation position. The touch feedback system can obtain the initial surface temperature of the target operating portion of the target touch operation using a temperature sensor. For example, based on the photoelectric effect, the target operating portion of the target touch operation emits infrared radiation signals of a specific frequency. The temperature sensor can receive these infrared radiation signals and calculate the initial surface temperature using a preset formula, achieving non-contact temperature measurement. For example, the formula T=(C2 / ln((C1 / V)+1)) can be used. 1 / 4 The surface temperature of the object is calculated, where T is the initial surface temperature of the target operating part; C1 and C2 are the sensor parameters of the temperature sensor; and V refers to the infrared radiation power of the target operating part.

[0085] In some embodiments, step S1212 may include obtaining the target feedback temperature based on the initial surface temperature and a preset temperature gain.

[0086] The initial surface temperature and a preset temperature gain can be summed to obtain the target feedback temperature. In this embodiment, after obtaining the initial surface temperature, the preset temperature gain can be directly increased, resulting in a temperature difference between the target feedback temperature and the initial surface temperature, providing tactile feedback to the user regarding temperature changes. In some embodiments, the preset temperature gain is 5 degrees Celsius, 6 degrees Celsius, 8 degrees Celsius, 10 degrees Celsius, etc. Alternatively, the initial surface temperature can be decreased by a certain amount to obtain the target feedback temperature.

[0087] In some embodiments, step S1212 may include: determining a temperature feedback range based on the initial surface temperature; and determining a target feedback temperature based on the temperature feedback range.

[0088] In this embodiment, after obtaining the initial surface temperature, a temperature feedback range can be obtained based on the initial surface temperature, and then a target feedback temperature can be determined based on the temperature feedback range. For example, determining the temperature feedback range based on the initial surface temperature includes: obtaining the minimum feedback temperature of the temperature feedback range based on the initial surface temperature and a first temperature gain; obtaining the maximum feedback temperature of the temperature feedback range based on the initial surface temperature and a second temperature gain; wherein the first temperature gain is less than the second temperature gain. For example, the initial surface temperature and the first temperature gain are summed to obtain the minimum feedback temperature of the temperature feedback range; the initial surface temperature and the second temperature gain are summed to obtain the maximum feedback temperature of the temperature feedback range. In some embodiments, the first temperature gain can be 4 degrees Celsius, 5 degrees Celsius, 6 degrees Celsius, etc.; the second temperature gain can be 9 degrees Celsius, 10 degrees Celsius, 11 degrees Celsius, etc. The touch feedback system can arbitrarily select a temperature from the temperature feedback range as the target feedback temperature; or, based on the user's personalized settings and weather factors, the minimum, maximum, or intermediate value in the temperature feedback range can be selected as the target feedback temperature. Of course, the initial surface temperature can also be reduced by a certain temperature range to obtain the temperature feedback range.

[0089] In some embodiments, step S122 may include: determining a target control voltage based on a target feedback temperature; and transmitting a temperature tactile feedback signal to the location of the target touch operation according to the target control voltage.

[0090] Because many factors influence the relationship between temperature and energy, such as wavelength, distance, time, and power, the conversion relationship between temperature and energy is quite complex. Therefore, embodiments of this application can experimentally fit temperature and voltage to pre-determine the voltage control at different temperatures. That is, multiple sets of mapping relationships between feedback temperature and control voltage can be pre-established, so that the target control voltage can be obtained from the mapping relationship based on the target feedback temperature. Then, a temperature tactile feedback signal is emitted according to the target control voltage, and the energy of the temperature tactile feedback signal is adjusted by the target control voltage, so that when the temperature tactile feedback signal comes into contact with the target operating part of the target touch operation, the energy is converted into heat energy, thereby changing the surface temperature of the target operating part to the target feedback temperature.

[0091] In summary, the touch feedback method provided in this application adjusts the voltage to regulate the energy of the temperature tactile feedback signal, thereby enabling the surface temperature of the target operating part to be changed to the target feedback temperature after the temperature tactile feedback signal is received. The energy adjustment method of the temperature tactile feedback signal in this application is simple, ensuring timely transmission of the temperature tactile feedback signal for the target touch operation, thus improving the touch feedback efficiency of the display screen.

[0092] In some embodiments, the touch feedback method provided in this application may further include:

[0093] Step S200: In response to the target touch operation, play the target feedback animation on the display screen.

[0094] In addition to tactile feedback such as temperature change, embodiments of this application can also provide visual feedback such as feedback animation. In response to a target touch operation, the touch feedback system plays a target feedback animation on the display screen. This target feedback animation can be a uniformly preset animation or a targeted preset animation based on different touch positions.

[0095] In some embodiments, step S200 may include: in response to a target touch operation, determining a target playback position of the target feedback animation in the display screen based on the position of the target touch operation; and displaying the target feedback animation at the target playback position. For example, if the touch area and the display area are the same, the target playback position may refer to the position of the target touch operation.

[0096] In some embodiments, the touch feedback method provided in this application may further include:

[0097] Step S300: In response to the target touch operation, play the target feedback audio.

[0098] In addition to tactile feedback such as temperature change, embodiments of this application can also provide auditory feedback such as sound effects. In response to a target touch operation, the touch feedback system plays a target feedback sound effect. This target feedback sound effect can be a uniformly preset sound effect, or it can be a specific preset sound effect based on the different touch positions.

[0099] In some embodiments, step S300 may include: in response to a target touch operation, determining a target feedback audio that matches the target touch operation; and playing the target feedback audio. The target feedback audio may be a feedback audio effect that matches the operation position or operation type of the target touch operation.

[0100] In summary, the touch feedback method provided in this application embodiment not only provides users with tactile feedback of temperature changes, but also provides users with visual feedback of feedback animations and / or auditory feedback of feedback sound effects. This not only enriches the interaction methods for the display screen, but also enhances touch feedback from multiple dimensions, further improving the user's touch experience.

[0101] The touch feedback method provided in this application embodiment will be described below with an example. In this example, the displayed screen is a floating screen.

[0102] Please see Figure 4 , Figure 4 This is a flowchart of a touch feedback method provided in an embodiment of this application. The touch feedback method may include the following steps S401 to S411:

[0103] Step S401: Enable the floating display function;

[0104] Step S402: The beam is displayed on the transmission screen;

[0105] Step S403: Display the floating display screen;

[0106] Step S404: Enable touch recognition function;

[0107] Step S405: Emit a touch recognition beam;

[0108] Step S406: Receive the touch-reflected beam;

[0109] Step S407: Determine whether the target reflected beam is received; the touch reflected beam includes the target reflected beam, and the optical path of the target reflected beam is within a preset range; if the target reflected beam is received, proceed from step S408 below; if the target reflected beam is not received, return to step S406.

[0110] Step S408: Send a temperature haptic feedback signal to the target touch operation location;

[0111] Step S409: Display the target feedback animation in the floating display screen;

[0112] Step S410: Play the target feedback sound effect;

[0113] Step S411: Determine whether the target touch operation is valid; if valid, proceed from step S412 below; if invalid, return to step S407.

[0114] Step S412: Display the screen operation corresponding to the target touch operation in the floating display screen.

[0115] In step S401, the floating display function can be activated via voice commands, AI gestures, touch buttons, touch icons, etc. In step S402, after the floating display function is activated, the touch feedback system emits a display beam to facilitate light field reconstruction by the negative refractive index flat lens, thereby displaying the floating display image in step S403.

[0116] In step S404, the touch recognition function can be activated simultaneously with the floating display function, or it can be activated before or after the floating display function. The touch recognition function can also be activated via voice commands, AI gestures, touch buttons, touch icons, etc. In step S405, after the touch recognition function is activated, the touch feedback system emits a touch recognition beam, and in step S406, the touch feedback system receives the touch reflection beam from the touch recognition beam.

[0117] In step S407, the touch feedback system determines whether a target reflected beam has been received based on the optical path length of the touch reflected beam, where the optical path length of the target reflected beam is within a preset range. If the target reflected beam is received, a target touch operation on the floating display screen is received.

[0118] In step S408, in response to the target touch operation, the touch feedback system emits a temperature tactile feedback signal to the location of the target touch operation to provide the user with tactile feedback of temperature changes. In step S409, in response to the target touch operation, the touch feedback system displays a target feedback animation on the floating display screen to provide the user with visual feedback. In step S410, in response to the target touch operation, the touch feedback system plays a target feedback sound effect to provide the user with auditory feedback. It should be understood that steps S408, S409, and S410 can be executed simultaneously or sequentially, etc., and this embodiment does not limit this.

[0119] In step S411, in response to the target touch operation, the touch feedback system determines whether the target touch operation is valid. If valid, the display content of the floating display screen is changed, and the screen operation corresponding to the target touch operation is displayed in the floating display screen. It should be understood that step S411 can be executed simultaneously with steps S408, S409, and S410, or sequentially, etc., and this application embodiment does not limit this.

[0120] It should be noted that after step S401, the user can turn off the floating display function at any time. For example, the user can turn off the floating display function through voice commands, AI gestures, touch buttons, touch icons, etc. The touch recognition function can be turned off at the same time as the floating display function, and the touch feedback system will stop emitting the screen display beam and the touch recognition beam.

[0121] related Figure 4 For details on the execution process of each step in the embodiments, please refer to the descriptions of other embodiments of this application, which will not be repeated here.

[0122] According to a second aspect of this application, embodiments of this application provide a touch feedback system.

[0123] The touch feedback system includes a touch recognition device and a temperature feedback device; the touch recognition device is used to identify the location of the target touch operation; the temperature feedback device is used to transmit a temperature tactile feedback signal to the location of the target touch operation.

[0124] In some embodiments, the temperature feedback device includes a temperature feedback controller and a first signal device; wherein the temperature feedback controller is used to control the first signal device to transmit a temperature tactile feedback signal to the location of the target touch operation.

[0125] In some embodiments, the temperature feedback device further includes a temperature sensor; wherein the temperature sensor is used to detect the initial surface temperature of the target operating portion; wherein the target operating portion refers to the operating body portion located at the target touch operation position; and the temperature feedback controller is used to control the first signal device to transmit a temperature tactile feedback signal to the target touch operation position based on the initial surface temperature.

[0126] In some embodiments, the touch recognition device includes a touch recognition controller and a second signal device; wherein the second signal device is used to emit a touch recognition beam and receive a touch reflection beam; wherein the touch recognition beam covers a touch area; and the touch recognition controller is used to identify the position of a target touch operation in the touch area based on the touch recognition beam and the touch reflection beam.

[0127] In some embodiments, the touch feedback system further includes a display controller, a display device, and an equivalent negative refractive index flat plate lens; the display controller is used to control the display device to emit a display beam so that the display beam is reconstructed after passing through the equivalent negative refractive index flat plate lens to obtain a display image.

[0128] In some embodiments, the touch area where the target touch operation is located overlaps with the display area where the display screen is located.

[0129] In some embodiments, the touch feedback system further includes a communication device, wherein the touch recognition device, the temperature feedback device, and the display controller communicate with each other through the communication device.

[0130] For example, if the display screen is a floating screen, please refer to [link / reference]. Figure 5 , Figure 5 This is a schematic diagram of a touch feedback system provided in an embodiment of this application. The touch feedback system includes a touch recognition controller 100, a temperature feedback controller 300, a display controller 400, a display device 500, an equivalent negative refractive index flat lens 600, a second signal device 710, a first signal device 720, and a temperature sensor 730.

[0131] The display controller 400 is used to provide electrical signal output to the display device 500 and to analyze and process changes in the display screen of the display device 500. For example... Figure 5 and 6 As shown, the display controller 400 can control the display device 500 to emit a display beam 510, which is the light source for the floating display image 200. The display beam 510 can be reconstructed into the floating display image 200 through optical components such as an equivalent negative refractive index flat lens 600.

[0132] The touch recognition controller 100 provides an electrical signal output to the second signal device 710 and analyzes and processes touch position information. For example, Figure 5 and 6 As shown, the touch recognition controller 100 can control the second signal device 710 to emit a touch recognition beam 110 and receive a touch reflection beam 120. The touch recognition beam 110 can cover the touch area 130, which can be the same as the display area of ​​the floating display screen 200. In addition, the touch recognition controller 100 is also used to provide touch position information to the display controller 400 and the temperature feedback controller 300.

[0133] The temperature feedback controller 300 is used to provide an electrical signal output to the first signal device 720, and to acquire the initial surface temperature of the target operating part of the target touch operation and to determine the target feedback temperature. For example, Figure 5 and Figure 6 As shown, the temperature feedback controller 300 can control the first signal device 720 to emit a temperature tactile feedback signal 310. The first signal device 720 can be located in the same position as the temperature sensor 730; for example, the temperature sensor 730 can also be integrated into the first signal device 720 to obtain the initial surface temperature of the target operating part. The temperature feedback controller 300 can adjust the energy of the temperature tactile feedback signal 310 by adjusting the voltage, thereby providing the user with different temperature sensations.

[0134] In the embodiments of this application, such as Figure 5 and Figure 6 As shown, the display controller 400, touch recognition controller 100, and temperature feedback controller 300 can reside in the same control system 000. The display controller 400, touch recognition controller 100, and temperature feedback controller 300 can be implemented as different controllers within the control system 000, and they can interact with each other via hardwired connections, wired networks, or wireless networks. Figure 6As shown, the control system 000 may further include a communication device 800, which is used for data storage and interaction between the touch recognition device (including the touch recognition controller 100), the temperature feedback device (including the temperature feedback controller 300), and the display controller 400 in the touch feedback system, such as the interaction of touch position information. Of course, in practical applications, any two of the display controller 400, the touch recognition controller 100, and the temperature feedback controller 300 can be implemented as the same controller, or the display controller 400, the touch recognition controller 100, and the temperature feedback controller 300 can be implemented as the same controller; this application embodiment does not limit this. For example, the display controller 400 and the touch recognition controller 100 are implemented as the same controller, and the temperature feedback controller 300 is implemented as another controller; or, the touch recognition controller 100 and the temperature feedback controller 300 are implemented as the same controller, and the display controller 400 is implemented as another controller; or, the display controller 400 and the temperature feedback controller 300 are implemented as the same controller, and the touch recognition controller 100 is implemented as another controller. When any two or three of the display controller 400, touch recognition controller 100, and temperature feedback controller 300 are implemented as the same controller, the operations they perform can be implemented by different functional modules within the same controller. For example, if the display controller 400, touch recognition controller 100, and temperature feedback controller 300 are implemented as the same controller A, the operations performed by the display controller 400 can be implemented by the display control module in controller A, the operations performed by the touch recognition controller 100 can be implemented by the touch recognition control module in controller A, and the operations performed by the temperature feedback controller 300 can be implemented by the temperature feedback control module in controller A.

[0135] In this embodiment, several reflectors can be added between the display device 500 and the equivalent negative refractive index flat lens 600, and between the equivalent negative refractive index flat lens 600 and the floating display screen 200, to change the direction of light and thus meet different installation requirements.

[0136] like Figure 7 As shown, the floating display screen 200 and the touch area 130 are located on the same plane; the equivalent negative refractive index flat lens 600 and several reflectors form an optical assembly; the display device 500 emits a display beam under the adjustment of the display controller 400, and can display feedback animation and play feedback sound effects; the temperature feedback controller 300 and the touch recognition controller 100 exchange information to emit temperature tactile feedback signals to the operation position of the touch operation.
