[0007] Optionally, if the angle of the left-hand vector is not within a preset first angle range and the angle of the right-hand vector is not within a preset second angle range, then the distance between the left and right hands is obtained based on the left-hand movement vector and the right-hand movement vector. If the distance between the left and right hands does not exceed a preset left and right hand distance threshold, then the current motion execution state is determined to be a scaling state.

[0008] Optionally, before the steps of calculating the angle between the left-hand vectors corresponding to the left-hand movement vector and calculating the angle between the right-hand vectors corresponding to the right-hand movement vector, the method further includes: If the length of the left-hand movement vector exceeds a preset first movement distance threshold, or the length of the right-hand movement vector exceeds a preset second movement distance threshold, then the steps of calculating the included angle of the left-hand vector corresponding to the left-hand movement vector and calculating the included angle of the right-hand vector corresponding to the right-hand movement vector are executed.

[0009] Optionally, calculating the angle between the left-hand vectors corresponding to the left-hand movement vector and the angle between the right-hand vectors corresponding to the right-hand movement vector includes: The positions where the left and right hands enter the triggered gesture state are taken as the initial positions, and the initial direction vectors are obtained based on the initial positions of the left and right hands; The angle between the left-hand movement vector and the initial direction vector is calculated as the angle between the left-hand vector and the right-hand movement vector.

[0010] Optionally, the method further includes: If the left or right hand is in the triggered gesture state, the hand movement vector of the left or right hand in the triggered gesture state is obtained, and the current virtual interactive object is controlled to move based on the hand movement vector.

[0011] Optionally, the method further includes: If both the left and right hands are in a non-triggered gesture state, then the current state is determined to be idle; In the idle state, the current virtual interactive object does not change with the movement of the left or right hand.

[0012] According to a second aspect of this application, a gesture interaction device is provided, the device comprising: The interaction object acquisition module is used to acquire the current virtual interaction object; The motion state determination module is used to obtain the first motion information of the left and right hands if both the left and right hands are in a preset trigger gesture state, and determine the current motion execution state based on the first motion information. The motion execution module is used to acquire second motion information of the left and right hands based on the motion execution state, and control the current virtual interactive object to move according to the second motion information.

[0025] Extended Reality (AR) is a suite of immersive technologies that use wearable devices to blend virtual content with the real world. With advancements in virtual reality (VR) technology, AR devices are becoming increasingly prevalent and are being used in numerous fields and scenarios, such as gaming and industrial operations.

[0026] Extended reality technology primarily operates by using image capture devices to capture and recognize users' gestures in the real world, then executing corresponding actions in the virtual world based on the recognition results. However, users' hands may tremble when performing gesture operations, and this tremor makes it difficult for existing technologies to accurately recognize similar gestures, leading to problems with the corresponding actions in the virtual world.

[0027] This embodiment provides a technical solution that can solve the above problems. The specific implementation of this application will be described in detail below with reference to the accompanying drawings.

[0028] This is an exemplary schematic diagram illustrating an application scenario of a gesture interaction method provided in an embodiment of this application. Figure 1 As shown, the application scenario includes at least a server 100 and a terminal 200 that can communicate with the server 100.

[0029] Understandably, the server 100 can be an independent electronic device or a cluster of multiple electronic devices; the terminal 200 can be a smartphone terminal, personal computer, tablet computer, vehicle terminal, etc., but is not limited to these.

[0030] In one possible implementation, server 100 and terminal 200 may respectively execute the gesture interaction method provided in the embodiments of this application, or, optionally, the gesture interaction method provided in the embodiments of this application may be partially executed in server 100 and partially executed in terminal 200.

[0031] like Figure 2 As shown, this embodiment provides a gesture interaction method, which may include the following steps: S1: Get the current virtual interaction object; In this embodiment, the current virtual interactive object can be acquired using an extended reality eye-tracking device. In one implementation, the current virtual interactive object can be selected by eye-tracking device gaze detection; in some implementations, the current virtual interactive object can also be selected by detecting the operator's left or right hand gestures. For example, if a grasping gesture is detected by the left or right hand towards an object, that object can be used as the current virtual interactive object.

[0032] It should be noted that this embodiment does not limit the method of obtaining the current virtual interactive object.

[0033] S2: If both the left and right hands are in a preset trigger gesture state, then obtain the first motion information of the left and right hands, and determine the current motion execution state based on the first motion information; In this embodiment, the trigger gesture state represents a signal to begin determining the current motion execution state. The trigger gesture state can be set according to the operator's operating habits. For example, the trigger gesture state can be set to a pinch state, in which case both the left and right hands are in the preset trigger gesture state, which can be understood as both the left and right hands being in a pinch state.

[0034] In this embodiment, when both the left and right hands are in the triggered gesture state, it indicates that the motion determination state has been entered. After entering the motion determination state, the first motion information of the left and right hands can be collected to determine the current motion execution state. The first motion information is the motion information of the left and right hands after entering the motion determination state, such as the direction and distance of translation, the direction and angle of rotation, etc.

[0035] It is understood that the left and right hands mentioned in this embodiment can be the left and right hands of the operator in the real world as collected by the eye device, or they can be the virtual left and right hands mapped in the virtual world. This embodiment does not limit them.

[0036] Understandably, step S2, where both the left and right hands are in a preset trigger gesture state, indicates that both the left and right hands have entered the acquisition range of the eye device. Being in a preset trigger gesture state can include entering the trigger gesture state after the left and / or right hand has entered the acquisition range of the eye device, and then being acquired by the eye device. It can also include the left and / or right hand entering the trigger gesture state outside the eye device's acquisition range, and then entering the acquisition range of the eye device, and then being acquired by the eye device.

[0037] In this embodiment, the step of determining the current motion execution state based on the first motion information is as follows: Figure 3 As shown, it may include the following steps: S21: Obtain the left-hand movement vector and the right-hand movement vector based on the first motion information; In one implementation, the first motion information may include the coordinates of the left and right hands before and after movement, thereby enabling the acquisition of the left-hand and right-hand movement vectors based on the first motion information. It is understood that the coordinates in the first motion information can be three-dimensional coordinates, and therefore the left-hand and right-hand movement vectors can be three-dimensional vectors. By acquiring the left-hand and right-hand movement vectors, the movement direction and distance of the left and right hands can be better expressed, thus making it easier to determine the current motion execution state.

[0038] S22: Calculate the angle between the left-hand vectors corresponding to the left-hand movement vector, and calculate the angle between the right-hand vectors corresponding to the right-hand movement vector; In this embodiment, step S22 may include the following sub-steps: First, obtain the initial direction vector based on the initial positions of the left and right hands; In this embodiment, the initial positions of the left and right hands are the positions of the left and right hands when both enter the triggered gesture state. It can be understood that, assuming the left hand enters the triggered gesture state first, and then the right hand enters the triggered gesture state, and the position of the left hand changes before the right hand enters the triggered gesture state, then the position of the left hand when the right hand enters the triggered gesture state, and the position of the right hand when the right hand enters the triggered gesture state, can be used as the initial positions of the left and right hands.

[0039] Furthermore, if both the left and right hands have entered the triggered gesture state before entering the collection range of the eye device, then the position of the left and right hands entering the collection range of the eye device can be used as the initial position of the left and right hands.

[0040] Next, the angle between the left-hand movement vector and the initial direction vector is calculated as the angle between the left-hand vector and the right-hand movement vector is calculated as the angle between the right-hand vector and the initial direction vector.

[0041] In this embodiment, based on the initial direction vector, the angle between the left-hand vector and the angle between the right-hand vector are calculated respectively, which can determine the movement of the left and right hands respectively, and thus accurately determine the operator's intention.

[0042] Meanwhile, since the hand may shift during the scaling operation, calculating the angle based on the coordinates of the left and right hands before and after movement could lead to misjudging the scaling state as a rotation state. Therefore, this embodiment uses the initial direction vector to calculate the angle between the left and right hand vectors, effectively achieving accurate angle calculation and thus accurate identification of the rotation and scaling states.

[0043] S23: If the included angle of the left-hand vector is within a preset first angle range, or the included angle of the right-hand vector is within a preset second angle range, then the current motion execution state is determined to be a rotation state. S24: If the angle of the left-hand vector is not within the preset first angle range and the angle of the right-hand vector is not within the preset second angle range, then the distance between the left and right hands is obtained based on the left-hand movement vector and the right-hand movement vector; S25: If the distance between the left and right hands does not exceed the preset left and right hand distance threshold, then the current motion execution state is determined to be a scaling state.

[0044] It is understandable that the rotation and scaling states are easily affected by hand operations, leading to misjudgments. Therefore, this embodiment effectively avoids misjudgments of the rotation and scaling states by using two different judgment methods to determine the order of conditions when both the left and right hands are in the triggered gesture state. It should be noted that since the judgment methods between the rotation and scaling states are relatively independent, the judgments in steps S22, S23 and steps S24, S25 can be interchanged under certain circumstances by adjusting the judgment logic, which will not be elaborated further.

[0045] Understandably, in order to reduce the impact of jitter, it is necessary to eliminate the interference caused by jitter before determining whether the motion execution state is a rotation state or a scaling state. Therefore, in one embodiment of this invention, before the steps of calculating the angle between the left-hand vectors corresponding to the left-hand movement vector and the angle between the right-hand vectors corresponding to the right-hand movement vector, the method further includes: If the length of the left-hand movement vector exceeds a preset first movement distance threshold, or the length of the right-hand movement vector exceeds a preset second movement distance threshold, then the steps of calculating the included angle of the left-hand vector corresponding to the left-hand movement vector and calculating the included angle of the right-hand vector corresponding to the right-hand movement vector are executed.

[0046] Understandably, if the length of the left-hand movement vector does not exceed the first movement distance, and the right-hand movement vector does not exceed the second movement distance, it indicates that the movement of the left and right hands is jittering and cannot be used to determine the movement execution state. In this case, the first movement information of the left and right hands can be reacquired until it is determined based on the first movement information that the length of the left-hand movement vector exceeds the first movement distance, or the right-hand movement vector exceeds the second movement distance; or, the left or right hand exits the triggered gesture state, indicating exiting the movement determination state.

[0047] S3: Based on the motion execution state, obtain the second motion information of the left and right hands, and control the current virtual interactive object to move according to the second motion information.

[0048] Understandably, step S2 determines the motion execution state. After determining the motion execution state, no control is performed on the current virtual interactive object. The first motion information is only used to provide information for determining the motion execution state. Therefore, in this embodiment, the motion of the current virtual interactive object is controlled by further obtaining the second motion information.

[0049] Understandably, the second motion information represents the motion information of the left and right hands in the motion execution state, and the second motion information matches the motion execution state.

[0050] In one implementation, the left hand movement vector and the right hand movement vector in the motion execution state can be obtained based on the second motion information, and then the current virtual interactive object can be controlled to move based on the left hand movement vector and the right hand movement vector.

[0051] For example, if the motion execution state is the rotation state, the left-hand movement vector and right-hand movement vector in the rotation state can be obtained based on the second motion information. Then, the included angle between the left-hand and right-hand vectors in the rotation state can be calculated, and the current virtual interactive object can be controlled to rotate based on the included angle. If the motion execution state is the scaling state, the left-hand movement vector and right-hand movement vector in the scaling state can be obtained based on the second motion information. A scaling factor can be calculated based on the left-hand and right-hand movement vectors, and the current virtual interactive object can be controlled to scale based on the scaling factor.

[0052] It should be noted that the motion execution state may also include other states. The specific judgment conditions and execution content are set according to the specific state situation, which will not be elaborated further here.

[0053] In one embodiment, the method further includes: If both the left and right hands are in a non-triggered gesture state, then the current state is determined to be idle; In the idle state, the current virtual interactive object does not change with the movement of the left or right hand.

[0054] Understandably, when both the left and right hands are in the triggered gesture state, it indicates that the motion determination state has been entered. If the left or right hand is exited from the triggered gesture state, the motion determination state will not be exited. When both the left and right hands are exited from the triggered gesture state, it indicates that the idle state has been entered and the motion determination state has been exited.

[0055] Similarly, after determining the motion execution state, if the left hand or right hand exits the trigger gesture state, the motion execution state is maintained. If the left hand or right hand that exited the trigger gesture state re-enters the trigger gesture state, the motion execution state continues. If both the left hand and right hand exit the trigger gesture state, the motion execution state is exited.

[0056] In one embodiment, the method further includes: If the left or right hand is in the triggered gesture state, the hand movement vector of the left or right hand in the triggered gesture state is obtained. If the vector length of the hand movement vector exceeds a preset third movement distance threshold, the current virtual interactive object is controlled to move based on the hand movement vector.

[0057] Understandably, when only one hand is detected in the triggered gesture state, the movement of the current virtual interactive object can be controlled based on the hand movement vector of the hand in the triggered gesture state. By separating the movement operation from other operations, conflicts between the movement operation and other operations can be better reduced, and misjudgments of operations can be avoided.
