[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0025] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0026] The first part of the present disclosure provides a Figure 1 and Figure 2 The tactile perception mask for virtual reality shown in the figure includes an outer shell 21, which has a shape corresponding to the outer contour of the human face and is a hard shell that covers the cheeks and lips of the user; an inner membrane cloth 22, whose edge is attached to and fixed to the edge of the outer shell 21; a PCB circuit board array, which is arranged on the outer shell 21 close to the inner membrane cloth 22 side, and has a heating function to heat up the inner membrane cloth 22 to simulate the tactile temperature; an ultrasonic generator array, which is supported by the PCB circuit board array, arranged between the PCB circuit board array and the inner membrane cloth 22, and after being equipped on the surface of the human facial skin, it acts on the human facial skin through the inner membrane cloth 22 with ultrasonic waves; an input unit 25, which is connected to the VR head display 1 and receives control instructions; and a control unit 26, which receives instructions from the input unit 25 and controls the operation of the PCB circuit board array.

[0027] In the above embodiment, the PCB circuit board array includes a plurality of PCB circuit boards 23, and the plurality of PCB circuit boards 23 are arranged on the inner side of the shell 21, and are mainly arranged on the inner side of the shell 21 corresponding to the positions of the cheeks and lips of the user. A gap is left between each two adjacent PCB circuit boards 23 and they are connected to each other through data lines to achieve data synchronization.

[0028] In the above embodiment, the ultrasonic generator array includes a plurality of ultrasonic generators 24, and the ultrasonic generators 24 emit ultrasonic waves to the user's facial skin surface. The plurality of ultrasonic generators 24 are mainly arranged on the PCB circuit board 23 at positions corresponding to the user's cheeks and lips, and the data of the plurality of ultrasonic generators 24 are synchronized through the circuits on the PCB circuit board 23. The number of ultrasonic generators 24 on each PCB circuit board 23 is not limited and is arranged according to actual needs. As a result, the user's face can be subjected to forces of different strengths and directions, especially the cheeks and lips, which can be subjected to more realistic tactile sensations, such as kissing, patting the face, etc.

[0029] In this embodiment, the tactile perception mask for virtual reality is connected to the external VR head display 1 and realizes data transmission. Specifically, the input part 25 of the mask is connected to the VR head display 1 through a data line, thereby receiving data from the VR head display 1 and transmitting the data to the control part 26.

[0030] More specifically, the control unit 26 is connected to the PCB circuit board array, so that the control unit 26 controls the multiple PCB circuit boards 23 and other components arranged on the multiple PCB circuit boards 23. Thus, the external VR head display 1 finally controls the tactile perception mask.

[0031] In some other embodiments, the device connected to the VR headset 1 and performing tactile actions on the user is not limited to the structure of the mask, and can take other forms to cover other parts of the user's body, such as hands, legs, feet, etc. Correspondingly, the shell 21 also has a shape corresponding to the outer contour of different parts of the human body. In addition, the distribution of the array of ultrasonic generators can also be adjusted in a focused manner according to the different parts of the user's body covered, and can be distributed in a specific position. Due to the strong directionality of ultrasonic waves, ultrasonic waves can still reach the skin surface of the corresponding body part of the user, but setting a larger number of ultrasonic generators 24 at a specific position can make the force on that part more accurate and comprehensive, and the tactile feeling more realistic.

[0032] In some other embodiments, multiple PCB circuit boards 23 may also be evenly arranged on the inner side of the housing 21 and connected to each other through lines; similarly, multiple ultrasonic generators 24 may also be evenly arranged on the multiple PCB circuit boards 23.

[0033] In the above embodiment, the ultrasonic wave emitted by the ultrasonic generator 24 is 40 Hz, which is an elastic mechanical vibration wave with a short wavelength. When the ultrasonic wave is emitted from the ultrasonic generator 24, it will present a concentrated beam of rays and move in a certain direction. The energy transmitted by the ultrasonic wave is very large. When the ultrasonic wave reaches the inner membrane cloth 22, the elastic inner membrane cloth 22 vibrates along with the ultrasonic wave. The inner membrane cloth 22 contacts the user's facial skin and transmits the vibration to the user's facial skin. The higher the frequency of the ultrasonic wave, the greater the energy obtained by the molecules of the inner membrane cloth 22, so that the vibration of the inner membrane cloth 22 is stronger, and the tactile sensation produced on the user's skin surface is more obvious.

[0034] In addition, the input unit 25 receives control instructions from the VR headset 1 and transmits the instructions to the control unit 26, which controls the operation of the ultrasonic generator array arranged on the PCB circuit board array. Different VR scenes need to provide different tactile sensations for users. The control unit 26 controls the operation of the ultrasonic generator array and can control the intensity of the ultrasonic waves emitted by multiple ultrasonic generators 24. On the one hand, by controlling the intensity of the ultrasonic waves emitted by the ultrasonic generator 24, the tactile sensations of different intensities felt by the user's facial skin surface are simulated; on the other hand, the ultrasonic wave has strong directionality, and by controlling the direction of the ultrasonic wave emitted by the ultrasonic generator 24, the tactile force direction of the user's facial skin surface is simulated; in addition, by comprehensively and focusedly setting the positions of multiple ultrasonic generators 24, the user's facial skin surface covered by the tactile perception mask can be fully stressed while the tactile sensation is more accurate and real. In summary, by setting the positions of multiple ultrasonic generators 24, the direction and intensity of ultrasonic waves, the real tactile feeling of the user's local skin is achieved from a multi-dimensional perspective, and the working conditions of the ultrasonic generator array are adjusted according to different virtual scenes, which is flexible and controllable.

[0035] In this embodiment, the mask further includes a position confirmation unit, which includes a plurality of displacement sensors 27, which are supported on a PCB circuit board array, arranged between the PCB circuit board array and the inner membrane cloth 22, and interlaced with a plurality of ultrasonic generators 24 and connected through the lines on the PCB circuit board 23, and finally realize the synchronization of data of the plurality of displacement sensors 27. The plurality of displacement sensors 27 can detect the straight-line distance between them and various positions of the user's face and simulate the user's facial curve at the current stop position of the mask. When the curve falls into the curvature interval set by the system, it indicates that the mask has covered the user's face. At this time, the control unit 26 can proceed to the next step of operation, which ensures the safety of the mask during use and prevents unnecessary losses caused by improper wearing.

[0036] In this embodiment, the type of the displacement sensor 27 may be an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor, etc., and an infrared distance sensor is preferred.

[0037] In this embodiment, the mask further includes a plurality of air outlets 28, which are arranged on the inner side of the upper part of the shell 21, between the ultrasonic generator array and the inner membrane cloth 22, and are respectively connected to the control unit 26 (the connection line between the ultrasonic generator array and the control unit 26 is not shown in the figure). The plurality of air outlets 28 can blow out wind in the direction of the inner membrane cloth 22. Specifically, the inner membrane cloth 22 is made of mesh silicone material. On the one hand, the texture of silicone can simulate the touch of human skin and provide users with a real tactile feeling; on the other hand, the mesh inner membrane cloth 22 has a plurality of small holes, so that the wind blown out of the plurality of air outlets 28 can pass through the inner membrane cloth 22 to act on the user's skin, and also play a ventilation role; in addition, the mesh silicone material makes the inner membrane cloth 22 elastic, leaving an elastic margin for the vibration of the inner membrane cloth 22.

[0038] In some other embodiments, the inner layer membrane cloth 22 may also be made of other elastic membrane cloths, as long as they are elastic and can allow the wind blown out of the air outlet 28 to act on the user's face.

[0039] In this embodiment, the mask further includes a temperature regulator 29, which is disposed on the PCB circuit board 23 at the inner edge of the shell 21, and is controlled by the control unit 26 through the circuit on the PCB circuit board 23. The temperature regulator 29 receives instructions from the control unit 26 to adjust the temperature inside the mask, and can cooperate with the heating function of the PCB circuit board 23 to adjust the temperature of the inner film cloth 22 according to the needs of the VR scene, simulating the temperature of tactile activities in the VR scene, such as the temperature of the lips when kissing, and the temperature when ice cubes touch the face; it can also cooperate with the air outlet 28 to simulate air flow in different weather conditions, such as warm wind in spring, cold wind in winter, etc., to provide users with a more realistic virtual reality experience.

[0040] In this embodiment, the input unit 25 is connected to the control unit 26 to achieve data transmission; the control unit 26 is connected to the PCB circuit board array, and the ultrasonic generator 24, the position confirmation unit and the temperature regulator 29 are all arranged on the PCB circuit board 23 and are respectively connected to the control unit 26 through the lines on the PCB circuit board 23, so that the control unit 26 controls the ultrasonic generator 24, the position confirmation unit and the temperature regulator 29; the air outlet 28 is respectively connected to the control unit 26, so that the control unit 26 controls the air outlet intensity, direction, etc. of the air outlet 28. In this way, the data from the VR head display 1 is transmitted to the mask, and the operation of each component in the mask is controlled by the control unit 26.

[0041] It should be noted that the specific locations of the input unit 25, the control unit 26, the position confirmation unit, the air outlet 28 and the temperature regulator 29 are not limited and can also be set at other locations as long as they can operate normally and do not hinder the normal operation of the ultrasonic generator array.

[0042] In this embodiment, the data acquired by the input unit 25 from the VR head display 1 and transmitted to the control unit 26 adopts a multi-dimensional matrix, and different dimensions correspond to the position of the ultrasonic generator 24, the direction and intensity of the ultrasonic wave emitted by the ultrasonic generator 24, so as to provide users with a more realistic situation experience from multiple dimensions of vision, hearing and touch.

[0043] In some other implementations, sensory experiences in other dimensions such as smell and taste may be added to further enhance the user's sense of reality.

[0044] In some other implementations, the VR headset may also be replaced with other forms of carriers such as VR glasses, as long as various virtual scenes can be converted into data and structured.

[0045] The second part of the present disclosure provides a Figure 3 The VR device shown has a tactile perception mask for virtual reality, and the VR device includes a VR head display 1 and a mask 2. The VR head display 1 is connected to the mask 2 through a line to achieve data synchronization, and converts various scenes applied to the VR head display 1 into data and performs structured construction, and finally provides a visual VR scene for the user. The VR head display 1 transmits various instructions to the mask 2, and the mask 2 receives the instructions from the VR head display 1 and performs tactile actions. According to the embodiments of the present disclosure, the following technical effects are achieved:
