Description

Technical Field

[0001] This application relates to the field of motion capture technology, and more specifically, to a motion capture glove and a motion capture method based on a switch structure. Background Art

[0002] Existing motion capture gloves used in VR (Virtual Reality), AR (Augmented Reality), and MR (Mixed Reality) devices are an important part of virtual reality technology. By configuring a large number of sensors on the gloves, they provide users with an intuitive way to interact with the virtual environment. Existing motion capture gloves usually include multiple inertial measurement unit (IMU) sensors, which are used to track the precise movements of the hand and fingers; some motion capture gloves also have bending sensors for detecting the degree of finger bending. Through the coordinated work of these sensors, the motion capture gloves can capture the user's hand movements in real time and convert the hand movements into corresponding actions in the virtual environment, thus achieving a highly immersive interaction experience.

[0003] Although existing motion capture gloves have made significant progress in providing an immersive experience, configuring a large number of sensors on the gloves also brings some technical drawbacks. The increase in the number of sensors on the gloves leads to an increase in the weight and volume of the gloves, which may affect the user's comfort and usage duration. A large number of sensors require higher data processing capabilities, which not only increases energy consumption but also may cause data processing delays, affecting the real-time nature of the interaction. The data fusion and synchronization between the sensors on the gloves is a complex process and is easily affected by external interference, thus affecting the accuracy of motion capture. The sensor-intensive design of existing motion capture gloves increases the production cost, making the price of motion capture gloves remain high and limiting their market penetration rate. The multi-sensor design of existing motion capture gloves affects the usage effect of the motion capture gloves and increases the production cost. Summary of the Invention

[0033] The multi-sensor design of existing motion capture gloves affects the use effect of the motion capture gloves and increases the production cost.

[0034] For the above reasons, the embodiments of the present application provide a motion capture glove based on a switch structure, including a signal processing component, a plurality of switch components, and a glove body. The plurality of switch components are correspondingly arranged with the plurality of fingers of the glove body. Each switch component includes a plurality of switch units. The plurality of switch units of each switch component are arranged at the finger tips and at least one finger joint of the glove body. The connection state of the switch unit changes with the bending state of the finger joint of the glove body and the squeezing state of the finger tip. The plurality of switch units of the plurality of switch components are respectively electrically connected to the signal processing component, and the signal processing component is used to output the connection state of the switch units of the plurality of switch components. In the embodiments of the present application, the structure of the motion capture glove is simplified through the switch structure, and there is no need to install a large number of sensors on the motion capture glove, which can improve the induction time of the motion capture glove, and at the same time simplify the structure of the motion capture glove, reduce the production cost and power consumption of the motion capture glove.

[0035] In some scenarios, a motion capture glove based on a switch structure according to an embodiment of the present application can be applied to motion capture gloves of VR (Virtual Reality) devices, AR (Augmented Reality) devices, and MR (Mixed Reality) devices, and can also be used in cooperation with a mobile phone or a computer for motion capture, which can improve the use effect of the motion capture glove.

[0036] The following specifically describes a motion capture glove based on a switch structure provided by the embodiments of the present application with specific examples.

[0037] Figure 1 The front view structural schematic diagram of an action capture glove based on a switch structure provided by an embodiment of the present application is as follows Figure 1 As shown, this action capture glove based on a switch structure includes a signal processing component 1, a plurality of switch components 2, and a glove body 3. The plurality of switch components 2 are correspondingly arranged with the plurality of fingers of the glove body 3. Each switch component 2 includes a plurality of switch units 21. The plurality of switch units 21 of each switch component 2 are arranged at the finger tips and at least one finger joint of the glove body 3. The connection state of the switch unit 21 changes with the bending state of the finger joints and the squeezing state of the finger tips of the glove body 3. The plurality of switch units 21 of the plurality of switch components 2 are respectively electrically connected to the signal processing component 1, and the signal processing component 1 is used to output the connection state of the switch units 21 of the plurality of switch components 2.

[0038] As Figure 1 shown, in terms of structure, this action capture glove based on a switch structure includes a signal processing component 1, a plurality of switch components 2, and a glove body 3. The glove body 3 is made of a soft material, and the glove body 3 is used to carry the signal processing component 1 and the plurality of switch components 2, so that the hand movements can be captured through the signal processing component 1 and the plurality of switch components 2.

[0039] As Figure 1 shown, the plurality of switch components 2 are correspondingly arranged with the plurality of fingers of the glove body 3, so that each switch component 2 detects the state of the plurality of fingers of the glove body 3 and realizes the action capture function.

[0040] In terms of structure, each switch component 2 includes a plurality of switch units 21. The plurality of switch units 21 of each switch component 2 are arranged at the finger tips and at least one finger joint of the glove body 3, so that the switch unit 21 can capture the hand movements at the finger tips and at least one finger joint of the glove body 3.

[0041] Exemplarily, when the switch unit 21 at the finger tip is squeezed, the switch unit 21 at the finger tip can capture the squeezing state of the finger tip.

[0042] It should be noted that the switch unit 21 of each switch component 2 can be arranged at the first joint counted from the palm, or can be arranged at the first joint and the second joint counted from the palm. The switch unit 21 can also be arranged at the second joint counted from the palm. The embodiment of the present application does not limit the setting position of the switch unit 21 of each switch component 2.

[0043] It should be noted that the setting positions and the setting numbers of the switch units 21 of different switch components 2 can be different. The embodiment of the present application does not limit the setting manner of the switch units 21 of different switch components 2.

[0044] During operation, the connection state of the switch unit 21 changes with the squeezing state of the glove body 3, enabling the switch unit 21 to output electrical signals corresponding to the bending state of the finger joints and the squeezing state of the finger tips of the glove body 3.

[0045] Structurally, multiple switch units 21 of multiple switch assemblies 2 are electrically connected to the signal processing assembly 1 respectively. The signal processing assembly 1 is used to output the connection states of the switch units 21 of the multiple switch assemblies 2, enabling the signal processing assembly 1 to output electrical signals representing hand movements and realizing the capture of hand postures.

[0046] The beneficial effect of the above implementation method is that the structure of the motion capture glove is simplified through the switch structure, eliminating the need to install a large number of sensors on the motion capture glove, improving the usage effect of the motion capture glove, and reducing the production cost of the motion capture glove at the same time.

[0047] The beneficial effect of the above implementation method is also that the motion sensing speed of the motion capture glove is improved through the switch structure. The motion sensing speed can reach the 2-millisecond level at the fastest, greatly reducing the motion sensing time, significantly reducing the power consumption of this motion capture glove, increasing the battery life of the motion capture glove, reducing the weight of the motion capture glove, and improving the usage effect of the motion capture glove.

[0048] In some implementation methods, the signal processing assembly 1 is used to output the number information of the multiple switch assemblies 2, the number information and connection states of the switch units 21 of each switch assembly 2. The signal processing assembly 1 is detachably connected to the glove body 3, and the multiple switch units 21 of the switch assembly 2 are integrally arranged on the glove body 3.

[0049] During operation, the multiple switch assemblies 2 and the switch units 21 of each switch assembly 2 can be numbered. Then, the information of the switch assemblies 2 and the switch units 21 of each switch assembly 2 can be identified through the numbers, and the corresponding relationship between the switch assemblies 2 and the switch units 21 of each switch assembly 2 and the finger joints can be determined.

[0050] During operation, the signal processing assembly 1 is used to output the number information of the multiple switch assemblies 2, the number information and connection states of the switch units 21 of each switch assembly 2, enabling the accurate determination of hand movements through the states of the switch assemblies 2 and the switch units 21 of each switch assembly 2 and the finger joints.

[0051] Structurally, the signal processing component 1 is detachably connected to the glove body 3, and the signal processing component 1 and the switch component 2 are connected by a cable, so that the signal processing component 1 can be reused, and the glove body 3 in the embodiment of the present application can be replaced after use, improving the convenience of use of the present motion capture glove.

[0052] Structurally, multiple switch units 21 of the switch component 2 are integrally arranged on the glove body 3, so that the glove body 3 and the multiple switch units 21 are replaced together after use, making the glove body 3 and the multiple switch units 21 easy to replace and reducing the cost of replacing the glove body 3 and the multiple switch units 21.

[0053] Exemplarily, the signal processing component 1 can be directly connected to an external power supply, and the signal processing component 1 can supply power to the switch component 2. A rechargeable battery power supply component that can be replaced can be arranged on the signal processing component 1, and the signal processing component 1 and the switch component 2 can also be powered by the rechargeable battery power supply component.

[0054] The beneficial effect of the above implementation is that the corresponding relationship between the switch component and the switch unit and finger joint of each switch component is determined through the numbering information, facilitating the recognition of hand movements.

[0055] The beneficial effect of the above implementation is also that the glove body and the multiple switch units are easy to replace, reducing the cost of replacing the glove body and the multiple switch units, and improving the convenience of use of the present motion capture glove.

[0056] In some implementations, the switch unit 21 includes a first support piece 211, a second support piece 212, a first electrode piece 213, a second electrode piece 214, and an elastic piece 215. The first support piece 211 and the second support piece 212 are arranged in parallel with each other. The first electrode piece 213 is arranged on the first support piece 211, the second electrode piece 214 is arranged on the second support piece 212, and the elastic piece 215 is arranged between the first support piece 211 and the second support piece 212.

[0057] Figure 2 A schematic cross-sectional structure diagram of a switch unit provided for an embodiment of the present application is shown in Figure 2As shown, the switch unit 21 includes a first support piece 211, a second support piece 212, a first electrode piece 213, a second electrode piece 214, and an elastic piece 215. The first support piece 211 and the second support piece 212 are arranged in parallel with each other. The first electrode piece 213 is disposed on the first support piece 211, and the second electrode piece 214 is disposed on the second support piece 212, such that the first support piece 211 and the second support piece 212 can support the electrode pieces of the switch unit. Cables for outputting switch signals can be respectively connected to the first electrode piece 213 and the second electrode piece 214 to output the connection state of the switch unit.

[0058] Exemplarily, the first electrode piece 213 and the second electrode piece 214 can be made of a conductive metal thin film, or the first electrode piece 213 and the second electrode piece 214 can also be made of a flexible printed circuit (FPC).

[0059] Exemplarily, the distance between the first electrode piece 213 and the second electrode piece 214 can be 0.2 mm to 0.5 mm.

[0060] Structurally, the elastic piece 215 is disposed between the first support piece 211 and the second support piece 212, such that the elastic piece 215 can support the first support piece 211 and the second support piece 212, so that when the first support piece 211 and the second support piece 212 are not squeezed, they are separated from each other, and further the first electrode piece 213 and the second electrode piece 214 are separated from each other, ensuring the switching function of the switch unit 21.

[0061] In some implementation manners, the first electrode piece 213 and the second electrode piece 214 are arranged close to each other. The first support piece 211 and the second support piece 212 can be squeezed and approach each other under the bending action of the finger joint of the glove body 3. When the first support piece 211 and the second support piece 212 approach each other, the first electrode piece 213 and the second electrode piece 214 are connected to each other, and when the first support piece 211 and the second support piece 212 are not squeezed, the first electrode piece 213 and the second electrode piece 214 are disconnected from each other.

[0062] Such as Figure 2As shown, in terms of structure, the first electrode sheet 213 and the second electrode sheet 214 are arranged close to each other. The first support sheet 211 and the second support sheet 212 can be squeezed and approach each other under the bending action of the finger joints of the glove body 3. Then, when the first support sheet 211 and the second support sheet 212 approach each other, the elastic sheet 215 is squeezed, causing the first electrode sheet 213 and the second electrode sheet 214 to be interconnected. At this time, the connection of the switch unit 21 is realized; when the first support sheet 211 and the second support sheet 212 are not squeezed, the first support sheet 211 and the second support sheet 212 are separated from each other by the elastic sheet 215, causing the first electrode sheet 213 and the second electrode sheet 214 to be disconnected. At this time, the disconnection of the switch unit 21 is realized.

[0063] The beneficial effect of the above implementation method is that the switch unit realizes the flat design of the switch unit through the mutual cooperation of the first support sheet, the second support sheet, the first electrode sheet and the second electrode sheet, simplifies the structures of the switch unit and the motion capture glove, and improves the use effect of the motion capture glove.

[0064] In some implementation methods, the first support sheet 211 and the second support sheet 212 include an intermediate plate 211a and two support plates 211b. The two support plates 211b are respectively hinged to both sides of the intermediate plate 211a. The two support plates 211b are of a rigid structure, the intermediate plate 211a is of a flexible structure, and the elastic sheet 215 is connected between the two support plates 211b of the first support sheet 211 and the second support sheet 212.

[0065] As Figure 2 As shown, in terms of structure, the first support sheet 211 and the second support sheet 212 include an intermediate plate 211a and two support plates 211b. The two support plates 211b are respectively hinged to both sides of the intermediate plate 211a, enabling the two support plates 211b to rotate relative to the intermediate plate 211a, so that the switch unit 21 can better fit the glove when the finger bends.

[0066] In terms of structure, the two support plates 211b are of a rigid structure, and the elastic sheet 215 is connected between the two support plates 211b of the first support sheet 211 and the second support sheet 212, enabling the elastic sheet 215 to be stably supported under the action of the first support sheet 211 and the second support sheet 212, ensuring the normal switching function of the switch unit 21.

[0067] In terms of structure, the intermediate plate 211a is of a flexible structure, enabling the intermediate plate 211a to adapt to the bending structure of the glove and improving the use effect of the switch unit 21.

[0068] The beneficial effect of the above implementation method is that the two support plates can rotate relative to the intermediate plate, enabling the switch unit to better fit the glove when the finger bends.

[0069] The beneficial effects of the above implementation method are also that the elastic sheet can be stably supported under the action of the first support sheet and the second support sheet, ensuring the normal switching function of the switch assembly; the middle plate 211a can adapt to the bending structure of the glove, improving the use effect of the switch assembly.

[0070] In some implementation methods, the first electrode sheet 213 is connected to the middle plate 211a of the first support sheet 211, the second electrode sheet 214 is connected to the middle plate 211a of the second support sheet 212, and a plurality of electrode bosses 201 with different heights are provided on the first electrode sheet 213 and the second electrode sheet 214. When different magnitudes of extrusion forces are applied to the first support sheet 211 and the second support sheet 212, the plurality of electrode bosses 201 with different heights on the first electrode sheet 213 and the second electrode sheet 214 are pushed to be connected, and the switch unit 21 outputs the connection states of the plurality of electrode bosses 201 with different heights.

[0071] Figure 3 Another cross-sectional structure schematic diagram of the switch unit provided by the embodiment of the present application is shown in Figure 3 As shown, the first electrode sheet 213 is connected to the middle plate 211a of the first support sheet 211, the second electrode sheet 214 is connected to the middle plate 211a of the second support sheet 212, and a plurality of electrode bosses 201 with different heights are provided on the first electrode sheet 213 and the second electrode sheet 214, so that the plurality of electrode bosses 201 can be used as electrodes for detecting different extrusion degrees.

[0072] During operation, the plurality of electrode bosses 201 are insulated from each other. When different magnitudes of extrusion forces are applied to the first support sheet 211 and the second support sheet 212, the plurality of electrode bosses 201 with different heights on the first electrode sheet 213 and the second electrode sheet 214 are pushed to be connected, and the switch unit 21 outputs the connection states of the plurality of electrode bosses 201 with different heights, thereby enabling the plurality of electrode bosses 201 to detect the bending degree of the finger joints or the magnitude of the extrusion force at the finger tips.

[0073] Exemplarily, the elastic sheet 215 can be set to have different elastic forces corresponding to the plurality of electrode bosses 201 under different extrusion degrees, which can improve the adaptation effect under different extrusion states.

[0074] In terms of structure, since the middle plate 211a is a flexible structure, the middle plate 211a can adapt to the extrusion degrees of the plurality of electrode bosses 201 with different heights of the glove, so that the plurality of electrode bosses 201 with different heights can be connected under the yielding of the flexible middle plate 211a when subjected to different magnitudes of extrusion forces, ensuring the adaptability of the electrode bosses with different extrusion degrees during use.

[0075] The beneficial effects of the above implementation method are that the degree of finger joint bending or the magnitude of the squeezing force at the finger tip can be detected through multiple electrode bosses, which can further improve the motion range of hand motion capture and enhance the effect of hand motion capture.

[0076] The beneficial effects of the above implementation method are also that multiple electrode bosses with different heights can be connected under the yielding of the middle plate of the flexible structure when subjected to squeezing forces of different magnitudes, ensuring the adaptability of electrode bosses with different squeezing degrees during use.

[0077] In some implementation methods, multiple electrode bosses 201 with different heights include a first electrode boss 201a with the smallest height and multiple second electrode bosses 201b with gradually increasing heights on both sides of the first electrode boss 201a. The support plate 211b is arranged on the side of the multiple second electrode bosses 201b away from the first electrode boss 201a.

[0078] As Figure 3 shown, in terms of structure, multiple electrode bosses 201 with different heights include a first electrode boss 201a with the smallest height and multiple second electrode bosses 201b with gradually increasing heights on both sides of the first electrode boss 201a. The first electrode boss 201a is the electrode for detecting the maximum squeezing degree, and the multiple second electrode bosses 201b are the electrodes for detecting the gradually increasing squeezing degree, enabling the multiple second electrode bosses 201b to accurately detect the state of gradually increasing squeezing degree on both sides of the first electrode boss 201a.

[0079] In terms of structure, the support plate 211b is arranged on the side of the multiple second electrode bosses 201b away from the first electrode boss 201a, enabling the support plate 211b to support from two peripheral directions of the multiple second electrode bosses 201b.

[0080] The beneficial effects of the above implementation method are that multiple second electrode bosses can accurately detect the state of gradually increasing squeezing degree on both sides of the first electrode boss simultaneously, improving the detection effect of the switch unit and enhancing the effect of hand motion capture.

[0081] In some implementation methods, a gyroscope 4 is also detachably connected to the glove body 3. The gyroscope 4 is used to obtain the angular velocity and acceleration of the glove in different directions. The gyroscope 4 includes a six-axis gyroscope and a three-axis gyroscope.

[0082] As Figure 1As shown, a gyroscope 4 is also detachably provided on the glove body 3. The gyroscope 4 is used to obtain the angular velocity and acceleration of the glove in different mutually perpendicular directions, so that the angular velocity and acceleration of the hand during movement can be detected through the gyroscope 4, and then the movement state of the hand can be recognized, realizing the spatial movement recognition function of the existing motion capture gloves.

[0083] Exemplarily, through the gyroscope, functions such as the swinging of the glove against the hand and pointing at an icon on the display screen can be realized.

[0084] In some implementation manners, in the recognition state of the swinging of the glove against the hand, by combining the squeezing operation of the finger on the switch component 21 at the finger tip, operations such as mouse clicking and file operations can be customized, improving the expandability of the control function of this motion capture glove.

[0085] It should be noted that the gyroscope 4 includes a six-axis gyroscope and a three-axis gyroscope, so that the six-axis gyroscope or the three-axis gyroscope can be used in different scenarios to realize the motion detection of the motion capture glove.

[0086] It should be noted that the gyroscope 4 is detachably connected to the glove body 3, so that the gyroscope 4 can be replaced according to different usage scenarios, improving the expandability of this motion capture glove and the usage effect of the motion capture glove.

[0087] The beneficial effect of the above implementation manner is that the angular velocity and acceleration of the hand during movement can be detected through the gyroscope, and then the angular velocity and acceleration of the hand can be detected, improving the motion capture effect.

[0088] The beneficial effect of the above implementation manner is also that by combining the detection of the gyroscope and the switch component on the glove, the expandability of the control function of this motion capture glove can be improved.

[0089] The beneficial effect of the above implementation manner is also that the gyroscope is detachably connected to the glove body, improving the expandability of this motion capture glove and the usage effect of the motion capture glove.

This method includes S110 to S120, and the following is a specific description of S110 to S120.

[0091] S110. When the bending state of the finger joints of the glove body 3 changes, obtain the connection state of each switch unit 21. Among them, when the first finger joint is in a bent state, the first switch unit at the first finger joint is in a connected state. When the first finger joint is in a straight state, the first switch unit at the first finger joint is in a disconnected state.

[0092] When performing motion capture, when the bending state of the finger joints of the glove body 3 changes, obtain the connection state of each switch unit 21, and then the hand motion can be captured according to the connection state of each switch unit 21.

[0093] When performing motion capture, when the first finger joint is in a bent state, the first switch unit at the first finger joint is in a connected state; when the first finger joint is in a straight state, the first switch unit at the first finger joint is in a disconnected state, so that the first switch unit at the first finger joint can detect the bending state of the first finger joint.

[0094] S120. Send the connection states of the multiple switch units 21 of the multiple switch assemblies 2 to the signal processing assembly 1, and the signal processing assembly 1 is used to centrally output the motion capture signals of the multiple switch units 21 of the multiple switch assemblies 2 for characterizing the bending states of the fingers.

[0095] After obtaining the bending state of each finger joint, the connection states of the multiple switch units 21 of the multiple switch assemblies 2 can be sent to the signal processing assembly 1, and the signal processing assembly 1 is used to centrally output the motion capture signals of the multiple switch units 21 of the multiple switch assemblies 2 for characterizing the bending states of the fingers. Subsequently, the motion capture signals can be decoded by an external motion decoding device to restore the hand motion, and the hand motion can be successfully captured.

[0096] The beneficial effect of the above implementation method is that it can detect the bending state of each finger joint, can accurately capture the hand motion, simplifies the motion detection process of the motion capture glove, and improves the use effect of the motion capture glove.

[0097] Figure 5 This is the front view structural schematic diagram of the second motion capture glove based on the switch structure provided by the embodiment of the present application. As Figure 5 shown, the above method further includes S210 to S220, and the following is a specific description of S210 to S220.

[0098] S210. When the bending degree of the finger joints of the glove body 3 changes, obtain the connection states of multiple electrode bosses 201 at different heights of each switch unit 21. Among them, when the first support piece 211 and the second support piece 212 are subjected to different magnitudes of extrusion forces, the switch unit 21 outputs the connection states of the electrode bosses 201 at different heights.

[0099] During motion capture, when the bending degree of the finger joints of the glove body 3 changes, the connection states of multiple electrode bosses 201 at different heights of each switch unit 21 can be obtained. When the first support piece 211 and the second support piece 212 are subjected to different magnitudes of extrusion forces, the switch unit 21 outputs the connection states of the electrode bosses 201 at different heights, so as to be able to detect different bending states at the finger joints of the glove.

[0100] S220. Send the connection states of the electrode bosses 201 at different heights of the multiple switch units 21 of the multiple switch assemblies 2 to the signal processing assembly 1, and the signal processing assembly 1 is used to centrally output motion capture signals of the multiple switch units 21 of the multiple switch assemblies 2 for characterizing the bending degree of the fingers.

[0101] During motion capture, the connection states of the electrode bosses 201 at different heights of the multiple switch units 21 of the multiple switch assemblies 2 can be sent to the signal processing assembly 1, and the signal processing assembly 1 is used to centrally output motion capture signals of the multiple switch units 21 of the multiple switch assemblies 2 for characterizing the bending degree of the fingers, so that the motion capture signals can reflect different bending degrees at the finger joints of the glove.

[0102] The beneficial effect of the above implementation method is that through the multiple switch units of the multiple switch assemblies capable of capturing the extrusion degree, the motion capture signals can reflect different bending degrees at the finger joints of the glove, improving the capture effect of hand movements.

[0103] Figure 6 FIG. is the front view structural schematic diagram of the third motion capture glove based on a switch structure provided by the embodiment of the present application. As Figure 6 shown, the above method further includes S310 to S320, and the following is a specific description of S310 to S320.

[0104] S310. When the switch assembly 2 has multiple switch units 21, obtain the time span value of the change in the bending state detected by the switch units 21 of the preset number of adjacent finger joints of the target finger.

[0105] When there are multiple switch units 21 in the switch assembly 2 during hand motion capture, in order to detect the working state of the switch units, the time span value of the change in the bending state detected by the switch units 21 of a preset number of adjacent finger joints of the target finger can be obtained. The time span value of the change in the bending state detected by the switch units 21 of adjacent finger joints is the time difference of the detected change in the bending state of adjacent finger joints. Furthermore, the detection sensitivity of the switch units 21 of adjacent finger joints can be verified based on the time difference of the detected change in the bending state of adjacent finger joints.

[0106] Exemplarily, the time span value of the change in the bending state detected by the switch units 21 of adjacent finger joints can be 0.5 s, 0.8 s, or 1.2 s.

[0107] Exemplarily, the adjacent finger joints can be the first joint and the second joint of the index finger, middle finger, or ring finger starting from the finger tip.

[0108] S320. Determine the time fluctuation value of a preset number of time span values. When the time fluctuation value is greater than the preset time fluctuation value, prompt for maintenance of the multiple switch units 21 of the target finger. Among them, the preset time fluctuation value includes the standard deviation or variance of a preset number of time span values.

[0109] When verifying the working state of the switch units 21 of adjacent finger joints, the time fluctuation value of a preset number of time span values can be determined, and then the working state of the switch units 21 of adjacent finger joints can be verified based on the time fluctuation value of a preset number of time span values.

[0110] When verifying the working state of the switch units 21 of adjacent finger joints, when the time fluctuation value is greater than the preset time fluctuation value, it indicates that the detection sensitivity of the switch units 21 of adjacent finger joints may be insufficient. Furthermore, it can be prompted to perform maintenance on the multiple switch units 21 of the target finger.

[0111] Exemplarily, the preset time fluctuation value includes the standard deviation or variance of a preset number of time span values.

[0112] Exemplarily, the above S310 to S320 can be processed by a signal processing component and output a signal prompting for maintenance of the multiple switch units 21 of the target finger.

[0113] The beneficial effect of the above implementation method is that the detection sensitivity of the switch units of adjacent finger joints can be verified based on the time difference of the detected change in the bending state of adjacent finger joints, improving the use effect of this motion capture glove.

[0114] Figure 7Schematic front view structure diagram of the fourth action capture glove based on a switch structure provided by an embodiment of the present application, as Figure 7 shown, the above method further includes S410 to S420, and the following is a specific description of S410 to S420.

[0115] S410. When the switch assembly 2 has multiple switch units 21, obtain the moment corresponding to the fist-clenching state detected by the switch unit 21 at the end of the target finger of the glove body 3, and at the same time obtain the moments corresponding to the bending states detected by the multiple switch units 21 of all finger joints of the target finger, and determine the difference between the moments corresponding to the multiple bending states and the moment corresponding to the fist-clenching state as the time detection difference.

[0116] To further detect the working state of the action capture glove, when the switch assembly 2 has multiple switch units 21, the moment corresponding to the fist-clenching state detected by the switch unit 21 at the end of the target finger of the glove body 3 can be obtained, and at the same time the moments corresponding to the bending states detected by the multiple switch units 21 of all finger joints of the target finger can be obtained, and the difference between the moments corresponding to the multiple bending states and the moment corresponding to the fist-clenching state can be determined as the time detection difference. The time detection difference characterizes the difference between the signal of the finger tip being squeezed detected by the switch unit 21 at the finger tip and the finger bending signal of the switch unit 21 at the finger joint. Furthermore, the working state of the action capture glove can be judged according to the time detection difference.

[0117] S420. Determine the minimum value of the multiple time detection differences of the target finger. When the minimum value of the multiple time detection differences is less than the preset time detection difference, prompt to repair the multiple switch units 21 of the target finger.

[0118] After obtaining the time detection difference, the minimum value of the multiple time detection differences of the target finger can be determined. Since it takes a certain amount of time for the finger to move from the bent state to the fist-clenching state, when the minimum value of the multiple time detection differences is less than the preset time detection difference, it means that the difference between the signal of the finger tip being squeezed detected by the switch unit 21 at the finger tip and the finger bending signal of the switch unit 21 at the finger joint is too small, indicating that the detection state of the switch unit 21 at the finger joint is not sensitive enough. At this time, it can be judged that the multiple switch units 21 of the target finger need to be repaired, and then a prompt can be given to repair the multiple switch units 21 of the target finger.

[0119] Exemplarily, the preset time detection difference can be 0.2 s, 0.3 s or 0.5 s.

[0120] The beneficial effects of the above implementation method are as follows: By determining the difference between the signal of the finger tip being squeezed detected by the switch unit at the finger tip and the finger bending signal of the switch unit at the finger joint, it is possible to determine the working state of the motion capture glove according to the difference detected over time, improving the detection effect of the working state of the motion capture glove.

[0121] The beneficial effects of the above implementation method are also as follows: It takes a certain amount of time for the finger to move from the bent state to the fist state. By using the minimum value of multiple time detection differences to detect the working states of multiple switch units of the target finger, the detection effect of the working state of the motion capture glove is improved.

[0122] In some implementation methods, the above method further includes: determining the fluctuation value of multiple time detection differences of the target finger. When the fluctuation value of multiple time detection differences is greater than the preset time detection fluctuation value, prompt for maintenance of all switch units 21 of the target finger. Among them, the fluctuation value of multiple time detection differences includes the standard deviation or variance of multiple time detection differences.

[0123] When detecting the working state of the switch unit, the fluctuation value of the detection time of the switch unit can be obtained. Specifically, the fluctuation value of multiple time detection differences of the target finger can be determined. When the fluctuation value of multiple time detection differences is greater than the preset time detection fluctuation value, it indicates that the stability of the sensitivity of the target finger detected when the finger moves from the bent state to the fist state is insufficient. Therefore, it can be prompted to perform maintenance on all switch units 21 of the target finger.

[0124] Exemplarily, the fluctuation value of multiple time detection differences includes the standard deviation or variance of multiple time detection differences.

[0125] The beneficial effects of the above implementation method are as follows: Verify the stability of the sensitivity of the target finger detected by the switch unit when the finger moves from the bent state to the fist state, further improving the detection effect of the working state of the motion capture glove.
