[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0041] Reference Figure 1 , Figure 1 This is a front view of an embodiment of a wristband device of the present application. The embodiment of the present application provides a wristband device, the wristband device comprising a wristband body 10 and the hand shooting component;

[0042] The hand shooting component is arranged on the side of the wristband body 10 facing the hand.

[0043] In this embodiment, the wristband body 10 may include four outer surfaces, namely, an inner ring surface, an outer ring surface 30, a first ring surface 20 facing the hand side, and a second annular side surface 40 facing the arm side. The hand shooting component may be at least one first camera 21, and the hand shooting component is arranged on the side of the wristband body 10 facing the hand, so as to realize the collection of the user's hand motion data, and to identify the user's corresponding gesture information.

[0044] The hand shooting component includes a camera array consisting of at least two first cameras 21 arranged at intervals of a first preset angle on a first annular side surface 20 of the wristband body 10 facing the hand.

[0045] In this embodiment, since a single camera cannot capture a complete gesture image due to a blocked viewing angle, at least two first cameras 21 arranged at a first preset angle on the first annular side surface 20 of the wristband body 10 facing the hand can form a camera array as the hand shooting component. For example, Figure 1 As shown, the number of the first cameras 21 is 6, and the first preset angle is 60°. The hand shooting component can be a camera array composed of 6 first cameras 21 arranged at 60° intervals on the first annular side 20 of the wristband body 10 facing the hand. In addition, it can be understood that the wristband device can also include an inertial measurement unit (IMU, InertialMeasurement Unit) for detecting hand motion data such as hand acceleration and angular velocity. By combining the inertial measurement unit and the hand shooting component, more types of gestures can be recognized to broaden the coverage of interactive scenes that can be recognized by the wristband device.

[0046] In this embodiment, the wristband device includes a wristband body 10 and a hand shooting component; the hand shooting component is provided on the side of the wristband body 10 facing the hand. Thus, the wristband device can collect the user's hand motion data through the hand shooting component, and then determine the corresponding gesture information according to the hand motion data, so that the user can interact through hand motions by wearing the wristband device. Compared with the more solidified interaction method of the handle, the method of realizing interaction through gesture recognition by the wristband device in this embodiment has a higher degree of freedom, can cover more interaction scenarios, and is more convenient for interaction.

[0047] See also Figure 2 and Figure 3 , Figure 2 This is a side view of an embodiment of the wristband device of the present application. Figure 3 This is a top view of an embodiment of a wristband device of the present application.

[0048] In a wristband device provided in another embodiment of the present application, an outer ring surface 30 of the wristband device is provided with an outer ring shooting component.

[0049] Since the wristband device is usually used in pairs at the same time, that is, one wristband device is worn on each hand. Therefore, in order to further improve the recognition accuracy of the user's hand motion data. In this embodiment, an outer ring shooting component is provided on the outer ring surface 30 of the wristband device, and the outer ring shooting component is at least one second camera 31. By setting the outer ring shooting component on the outer ring surface 30 of the wristband body 10, data collection of the hand motion of the user's other hand (that is, the hand of the user not wearing the wristband device) is realized as supplementary hand data, and the hand motion data collected by the hand shooting component is supplemented to improve the recognition accuracy of the gesture information corresponding to the user. Exemplarily, the user's first hand (such as the left hand) wears a first wristband device, and the second hand (such as the right hand) wears a second wristband device. Then, the supplementary hand data of the second hand can be obtained based on the outer ring shooting component of the first wristband device, and / or the supplementary hand data of the first hand can be obtained based on the outer ring shooting component of the second wristband device. Therefore, in this embodiment, the supplementary hand data collected by the outer ring shooting component and the hand motion data collected by the hand shooting component can be used as new hand motion data for gesture recognition, thereby effectively improving the recognition accuracy of the gesture information corresponding to the user.

[0050] The outer ring shooting component includes a camera array composed of at least two second cameras 31 arranged on the outer ring surface 30 at a second preset angle interval.

[0051] In this embodiment, if only one second camera 31 is provided on the outer ring surface 30, the user's other hand may not be photographed due to the obstruction of the viewing angle. Therefore, at least two second cameras 31 arranged at intervals of a second preset angle on the outer ring surface 30 of the wristband body 10 may form a camera array as the outer ring photographing component. For example, Figure 2 and Figure 3 As shown, the number of the second cameras 31 is 6, and the second preset angle is 60°. The outer ring shooting component can be a camera array composed of 6 second cameras 31 arranged at 60° intervals on the outer ring surface of the wristband body.

[0052] In this embodiment, an outer ring shooting component is provided on the outer ring surface 30 of the wristband device, so that supplementary hand data of the user's other hand can be collected based on the outer ring shooting component of the wristband device, thereby effectively improving the recognition accuracy of the gesture information corresponding to the user.

[0053] See also Figure 4 , Figure 4 This is a rear view of an embodiment of the wristband device of the present application. Figure 4 This is a rear view of an embodiment of the wristband device of the present application.

[0054] In a wristband device provided in another embodiment of the present application, the wristband device further includes a projection input component;

[0055] The projection input component is arranged on the side of the bracelet body 10 facing the arm, so as to project a preset virtual keyboard on the arm for information input.

[0056] In this embodiment, the projection input component is used to project a preset virtual keyboard on the arm and receive user operation actions on the preset virtual keyboard to implement information input. Figure 4 As shown, the projection input component includes a laser projector 41, an infrared transmitter 42 and a distance measuring camera 43 arranged on the second annular side surface 40 of the wristband body 10 facing the arm. The laser projector 41 is used to project a preset virtual keyboard on the arm, and the infrared transmitter 42 is used to emit an infrared signal to cover the preset virtual keyboard. Since the infrared signal will be reflected by the finger, when the user operates the preset virtual keyboard, the distance measuring camera 43 is used to detect the emission signal of the infrared signal and measure the distance of the emission signal to identify the user's operation action on the preset virtual keyboard and obtain the user's input operation information on the preset virtual keyboard.

[0057] In this embodiment, in view of the fact that it is too cumbersome and difficult to input information using a handle in an existing virtual reality device, a projection input component is provided on the side of the wristband body 10 facing the arm to project a preset virtual keyboard on the arm for information input. Thus, the convenience of information input in the virtual reality device is improved.

[0058] In addition, the present application also provides a virtual reality system, which includes a virtual reality device and at least one bracelet device as described above. It can be understood that the virtual reality device is a device that can create and experience a virtual world. In the case where the virtual reality system includes multiple bracelet devices, the components configured in each bracelet device in the virtual reality system may be the same or different. Exemplarily, the bracelet device in the virtual reality system includes a first bracelet device and a second bracelet device. The first bracelet device includes a first bracelet body, a first hand shooting component, and a first outer ring shooting component; the second bracelet device includes a second bracelet body, a second hand shooting component, a second outer ring shooting component, and a projection input component.

[0059] Reference Figure 5 , Figure 5 This is a flowchart of an embodiment of a control method for a virtual reality system of the present application. It should be noted that although a logical sequence is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown here.

[0060] In one embodiment of the present application, a control method for a virtual reality system is provided, which is applied to the virtual reality system as described above. The control method includes:

[0061] Step S100, in response to the gesture recognition instruction of the virtual reality device, collecting hand motion data based on the hand shooting component of the wristband device;

[0062] Step S200: determining corresponding gesture information according to the hand motion data.

[0063] In this embodiment, after the virtual reality device issues a gesture recognition instruction, the hand motion data can be collected based on the hand shooting component of the wristband device in response to the gesture recognition instruction of the virtual reality device. Figure 6 , Figure 6 6, the first shooting range F1 (i.e. Figure 6 If the area between the two thin solid lines at an angle in the figure includes the user's hand, the hand shooting component can collect the hand motion data of the user's hand.

[0064] Then, the gesture information corresponding to the user wearing the bracelet device can be identified according to the hand motion data. The hand motion data may include the hand motion image captured by the hand shooting component. Exemplarily, the hand motion data may be input into a pre-trained gesture recognition model to obtain the gesture information corresponding to the hand motion data. It is also possible to use the gesture model corresponding to the hand motion data component as the gesture information corresponding to the hand motion data. In this embodiment, it can be understood that step S200 can be performed by the bracelet device, that is, the hand shooting component of the bracelet device collects the hand motion data, and determines the corresponding gesture information according to the hand motion data. Then the bracelet device sends the gesture information to the virtual reality device. Step S200 can also be performed by the virtual reality device, that is, the hand shooting component of the bracelet device collects the hand motion data and sends the hand motion data to the virtual reality device; the virtual reality device determines the corresponding gesture information according to the hand motion data. In addition, the bracelet device may also include an inertial measurement unit for detecting hand motion data such as acceleration and angular velocity of the hand. Then the hand motion data and the hand action data are used as new hand action data to perform subsequent operations. By combining the inertial measurement unit and the hand shooting component, more types of gestures can be identified to broaden the interactive scene coverage that the wristband device can identify.

[0065] Furthermore, since the wristband devices are usually used in pairs at the same time, i.e., one wristband device is worn on each hand. In order to further improve the accuracy of the user's hand motion data, an outer ring shooting component can be provided on the outer ring surface of the wristband device. In this embodiment, the supplementary hand data collected by the outer ring shooting component can be used to supplement the hand motion data collected by the hand shooting component, thereby improving the recognition accuracy of the user's corresponding gesture information. Figure 7 , Figure 7 Schematic diagram of the shooting scene of the outer ring shooting component involved in the embodiment of the present application. In Figure 7, the wristband device in the virtual reality system includes a first wristband device B1 and a second wristband device B2. The first wristband device B1 includes a first wristband body, a first hand shooting component and a first outer ring shooting component; the second wristband device B2 includes a second wristband body, a second hand shooting component and a second outer ring shooting component. Figure 7 In the example, the user's first hand (such as the left hand) wears a first bracelet device B1, and the second hand (such as the right hand) wears a second bracelet device B2. Figure 7 It can be seen that the second shooting range F2 (i.e. Figure 7 If the shooting range of the first outer ring shooting component of the first wristband device B1 also includes the user's second hand, then the first wristband device B1 can capture the supplementary hand data of the second hand through the first outer ring shooting component, and then the hand motion data of the first hand and the supplementary hand data of the first hand can be captured by the first hand shooting component of the first wristband device B1 as new hand motion data of the first hand. Similarly, the shooting range of the first outer ring shooting component of the first wristband device B1 will also include the user's second hand, then the first wristband device B1 can capture the supplementary hand data of the second hand through the first outer ring shooting component, and then the hand motion data of the second hand and the supplementary hand data of the second hand can be captured by the second hand shooting component of the second wristband device B2 as new hand motion data of the first hand. Therefore, in this embodiment, the supplementary hand data collected by the outer ring shooting component and the hand motion data collected by the hand shooting component can be used as new hand motion data for gesture recognition, thereby effectively improving the recognition accuracy of the gesture information corresponding to the user.

[0066] In this embodiment, by responding to the gesture recognition instruction of the virtual reality device, hand motion data is collected based on the hand shooting component of the bracelet device; and the corresponding gesture information is determined according to the hand motion data. Thus, the user can interact through hand movements by wearing the bracelet device. Compared with the more rigid interaction method of the handle, the method of realizing interaction through gesture recognition of the bracelet device in this embodiment has a higher degree of freedom, can cover more interaction scenarios, and is more convenient for interaction.

[0067] Reference Figure 8 , Figure 8 This is a flow chart of another embodiment of the control method of the virtual reality system of the present application. It should be noted that the same or similar contents as the above embodiment can be referred to the above introduction and will not be repeated in the following.

[0068] In another embodiment of the present application, a control method for a virtual reality system is provided, wherein the wristband device further includes a projection input component, and the projection input component is disposed on a side of the wristband body facing the arm;

[0069] The control method further comprises:

[0070] Step A10, controlling the virtual reality device to enter a perspective mode;

[0071] Step A20, in response to the information input instruction of the virtual reality device, projecting a preset virtual keyboard on the arm based on the projection input component;

[0072] Step A30, collecting input operation information of the user on the preset virtual keyboard in the perspective mode based on the projection input component;

[0073] Step A40: determining corresponding user input information according to the input operation information.

[0074] In this embodiment, it should be noted that the perspective mode is a mode in which the virtual reality device captures an external environment image of the external environment through a camera and displays the external environment image on the display screen of the virtual reality device, so as to achieve the effect of a user seeing through the external environment when using the virtual reality device.

[0075] Exemplarily, since the user cannot see the external environment when using the virtual reality device, it is necessary to control the virtual reality device to enter the perspective mode to achieve the effect of the user seeing through the external environment. After the virtual reality device sends an information input instruction, in response to the information input instruction of the virtual reality device, a preset virtual keyboard is projected on the arm based on the projection input component. It can be understood that step A10 and step A20 can be executed simultaneously, or step A10 can be executed first and then step A20, or step A20 can be executed first and then step A10. The projection input component includes a laser projector, an infrared transmitter and a ranging camera arranged on the second annular side surface of the bracelet body facing the arm. See. Fig. 9 , Fig. 9 This is a scene diagram of another embodiment of the control method of the virtual reality system of the present application. The laser projector is used to project a preset virtual keyboard 50 on the arm, and the infrared transmitter is used to send an infrared signal (i.e. Fig. 9 The area between the two thick solid lines at an angle in the figure) covers the preset virtual keyboard 50. Since the infrared signal will be reflected by the finger, when the user operates the preset virtual keyboard 50, the ranging camera is used to detect the emission signal of the infrared signal and measure the emission signal to identify the user's operation action on the preset virtual keyboard 50, and obtain the user's input operation information on the preset virtual keyboard 50. Among them, the input operation information may include the operation coordinates when the user operates the preset virtual keyboard. Then, the input operation information can be matched with the coordinates of each key on the preset virtual keyboard to obtain the corresponding user input information. In this embodiment, it can be understood that step A40 can be performed by the wristband device, that is, the wristband device determines the corresponding user input information according to the input operation information. Then the wristband device sends the user input information to the virtual reality device. Step S200 can also be performed by the virtual reality device, and the wristband device sends the input operation information to the virtual reality device, and the virtual reality device determines the corresponding user input information according to the input operation information.

[0076] In addition, since the dominant hand of the user is different, step S200 includes: in response to the information input instruction of the virtual reality device, obtaining the wearing hand of the bracelet device provided with the projection input component; if the wearing hand is the left hand, projecting a first preset virtual keyboard on the arm of the wearing hand based on the projection input component; if the wearing hand is the right hand, projecting a second preset virtual keyboard on the arm of the wearing hand based on the projection input component, wherein the first preset virtual keyboard and the second preset virtual keyboard are symmetrical images. This embodiment can adapt to users with different dominant hands, avoid the inconvenience of operation caused by different dominant hands of users, and improve the convenience of interaction.

[0077] In this embodiment, the virtual reality device is controlled to enter the perspective mode; in response to the information input command of the virtual reality device, a preset virtual keyboard is projected on the arm based on the projection input component; the user's input operation information on the preset virtual keyboard in the perspective mode is collected based on the projection input component; and the corresponding user input information is determined according to the input operation information. In view of the fact that the existing virtual reality device uses a handle to input information, which is too cumbersome and difficult, this embodiment improves the convenience of information input of the virtual reality device by projecting a virtual keyboard on the arm to realize information input.

Among them, the communication bus 1002 is used to realize the connection and communication between these components.
