[0002] VR (Virtual Reality) technology can provide users with an immersive virtual world experience. For VR games, players typically control the movement of a virtual character in the virtual world by changing their own position in the real world, thereby changing the virtual scene's display position.

[0003] In related technologies, the movement speed of the controlled virtual character in the virtual scene is consistent with the movement speed of the game player in the real environment. Due to the constraints of the real environment space, the game player cannot move long distances, which causes the movement of the controlled virtual character to be restricted. As a result, the display position of the virtual scene cannot be adjusted over a long distance, and it cannot be well applied to virtual scenes with a larger spatial range.

[0012] In an exemplary embodiment of the present disclosure, the hand state of the target object includes a hand rotation angle of the target object.

Some of the block diagrams shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0036] In related technologies, such as VR games, the player's absolute position in the real environment is often used to change the virtual character's position, thereby changing the display position of the virtual scene. Due to the limitations of real-world spatial dimensions, gamers cannot move over long distances, which creates inconveniences for the management and application of large-scale virtual scenes such as SLGs (Simulation Games).

[0037] In view of one or more of the above problems, an exemplary embodiment of the present disclosure provides a display position adjustment method, which can be applied to VR interaction scenarios such as SLG that require the display position of the virtual scene to be adjusted remotely, and can be deployed on a VR interaction platform that can communicate with a somatosensory device.

[0038] An exemplary embodiment of the present disclosure provides a display position adjustment method, such as Figure 1 As shown, the target object interacts with the virtual scene through the somatosensory device worn by the target object, which may specifically include the following steps S110 to S130:

[0039] Step S110, in response to a triggering operation of a display position adjustment event, determining a first distance between the head and the hand of the target object, the first distance being the distance between the head and the hand of the target object when the display position adjustment event is triggered;

[0040] Step S120, in response to the movement operation of the target object's head and / or hand, determining a second distance between the target object's head and hand, the second distance being the distance between the target object's head and hand after the target object's head and / or hand moves;

[0041] Step S130 , determining a target change distance corresponding to the current display position of the virtual scene according to the first distance and the second distance, and adjusting the current display position of the virtual scene according to the target change distance.

[0042] During this display position adjustment process, the current display position of the virtual scene is rapidly adjusted based on the changes in the target subject's head and hand positions. This, on the one hand, overcomes the spatial constraints of the real scene during virtual reality interaction, allowing for compatibility with larger virtual scenes and enriching the interactive experience. On the other hand, it avoids errors caused by absolute displacement due to the target subject's body movement, improving the precision of target subject control during virtual scene display position adjustment.

[0043] The following are Figure 1 Each step is described in detail.

[0044] Step S110 , in response to a triggering operation of a display position adjustment event, determining a first distance between the head and hand of the target object, where the first distance is the distance between the head and hand of the target object when the display position adjustment event is triggered.

[0045] A display position adjustment event refers to a VR interaction event that controls the change in the display position of a virtual scene. The triggering operation of the display position adjustment event may include one or more specific gestures of the target object. Optionally, the triggering operation of the display position adjustment event may include the target object's hand being in a fist state. It should be noted that the hand involved in the triggering operation of the display position adjustment event can be the right hand or the left hand, and can be set specifically according to the daily behavior habits of the target object, and is not specifically limited here.

[0046] The target object refers to an object in the real scene that can interact with the virtual scene. The target object can control the behavior of the virtual character in the virtual scene, for example, it can control the virtual character to move forward or backward in the virtual scene.

[0047] Taking VR gaming as an example, the target object may be a gamer wearing a motion sensing device. The motion sensing device can be an electronic device that can sense the player's physical state, such as a VR helmet or handheld device that can sense the position of the player's head or hands.

[0048] The first distance is the distance between the target object's head and hand when the display position adjustment event is triggered. The distance between the target object's head and hand can be determined based on the position of the target object's head and hand. Specifically, when the display position adjustment event is triggered, the position of the target object's head and hand can be sensed by a somatosensory device, and the first distance can be obtained based on the position of the target object's head and hand.

[0049] In an optional embodiment, the first distance between the target object's head and hand is determined, such as Figure 2 As shown, this can be achieved by the following steps:

[0050] Step S210, obtaining the first position coordinates of the target object's head and the second position coordinates of the target object's hand;

[0051] Step S220 , obtaining a first distance between the target object's head and hand based on the first position coordinates of the target object's head and the second position coordinates of the target object's hand.

[0052] The first position coordinates are the head position coordinates of the target object when the display position adjustment event is triggered, and the second position coordinates are the hand position coordinates of the target object when the display position adjustment event is triggered.

[0053] It should be noted that when determining the first distance, the second position coordinate can be the right hand position coordinate of the target object, or the left hand position coordinate of the target object. It can be set according to the daily behavior habits of the target object or the wearing condition of the VR somatosensory device. No specific limitation is made here.

[0054] For example, if the first position coordinates of the target object's head are (a, b, c) and the first position coordinates of the target object's hand are (d, e, f), then S1 can be calculated as [(ad) 2 +(be ) 2+(cf) 2 ]1 / 2 obtains the first distance, where S1 represents the first distance.

[0055] Figure 2 The steps shown determine a first distance based on the position coordinates of the target object's head and hand at the moment the display position adjustment event is triggered, and use the first distance as the initial distance between the target object's head and hand, so as to determine the relative displacement between the target object's head and hand based on the initial distance, thereby avoiding the absolute displacement caused by the target object's body movement.

[0056] Step S120, in response to the movement operation of the target object's head and / or hand, determine the second distance between the target object's head and hand, the second distance being the distance between the target object's head and hand after the target object's head and / or hand moves.

[0057] Hand movement operations may include, but are not limited to, upward, downward, left, and right movement operations. Head movement operations may include, but are not limited to, upward, downward, left, and right movement operations. The specific movement direction of the movement operation can be determined by the target object and is not specifically limited in this disclosure.

[0058] After the display position adjustment event is triggered, the movement status of the target object's head and / or hand can be monitored in real time. If the target object's head and / or hand moves, the second distance between the target object's head and hand can be determined based on the position of the target object's head and the position of the hand after the target object's head and / or hand move.

[0059] In an optional embodiment, the second distance between the target object's head and hand is determined, such as Figure 3 As shown, this can be achieved by the following steps:

[0060] Step S310, obtaining the third position coordinates of the target object's head and the fourth position coordinates of the target object's hand;

[0061] Step S320 : Obtaining a second distance between the target object's head and hand based on the third position coordinates of the target object's head and the fourth position coordinates of the target object's hand.

[0062] Among them, the third position coordinates are the head position coordinates of the target object after the head and / or hand of the target object moves, and the fourth position coordinates are the hand position coordinates of the target object after the head and / or hand of the target object moves.

[0063] For example, if the third position coordinates of the target object's head are (a, b, c) and the fourth position coordinates of the target object's hand are (g, h, i), then S2 can be calculated as [(ag) 2 +(bh) 2 +(ci) 2 ]1 / 2 obtains the second distance, where S2 represents the second distance.

[0064] It should be noted that the fourth position coordinate and the second position coordinate can be the position coordinates of the same hand of the target object at different times. For example, if the second position coordinate is the position coordinate of the left hand of the target object when the display position adjustment event is triggered, the fourth position coordinate is the position coordinate of the left hand of the target object after the head and / or hand of the target object moves; if the second position coordinate is the position coordinate of the right hand of the target object when the display position adjustment event is triggered, the fourth position coordinate can be the position coordinate of the right hand of the target object after the head and / or hand of the target object moves. In addition, the fourth position coordinate and the second position coordinate can be the position coordinates of different hands of the target object at different times. For example, if the second position coordinate is the position coordinate of the left hand of the target object when the display position adjustment event is triggered, the fourth position coordinate is the position coordinate of the right hand of the target object after the head and / or hand of the target object moves; if the second position coordinate is the position coordinate of the right hand of the target object when the display position adjustment event is triggered, the fourth position coordinate can be the position coordinate of the left hand of the target object after the head and / or hand of the target object moves.

[0065] Figure 3 The steps shown determine the real-time distance between the target object's head and hands so as to determine the relative displacement between the target object's head and hands based on the initial distance, thereby avoiding the absolute displacement caused by the target object's body movement, thereby improving the accuracy of the virtual scene display position adjustment.

[0066] like Figure 4A As shown, an example diagram of the positions of the head and hands of the target object when the display position adjustment event is triggered is provided, wherein x1, y1, and z1 are the coordinate differences between the position coordinates corresponding to the head of the target object 401 and the position coordinates corresponding to the hand of the target object 401 when the display position adjustment event is triggered; Figure 4B As shown, an example diagram of the positions of the head and hands of the target object after the head and / or hands move is provided, wherein x2, y2, and z2 are the coordinate differences between the position coordinates corresponding to the head of the target object 401 and the position coordinates corresponding to the hand of the target object 401 after the head and / or hands of the target object 401 move.

[0067] Step S130 , determining a target change distance corresponding to the current display position of the virtual scene according to the first distance and the second distance, and adjusting the current display position of the virtual scene according to the target change distance.

[0068] The target change distance refers to the distance the current display position of the virtual scene needs to move under the control of the target subject's head and / or hand movement. The relative difference between the first distance and the second distance is used as reference data for the adjustment required for the current display position of the virtual scene. The larger the difference between the first and second distances, the larger the target change distance.

[0069] For example, Figure 5A This is a scene display example diagram before the virtual scene display position is adjusted. Figure 5B This is a scene display instance diagram after the virtual scene display position is adjusted.

[0070] Taking SLG games as an example, the game camera follows the movement of the virtual character controlled by the game player, and the virtual scene display position can be determined by the game screen captured by the game camera. Therefore, when the current display position of the virtual scene is adjusted based on the target change distance, the virtual character in the virtual scene can be controlled to move based on the target change distance to achieve the adjustment of the current display position of the virtual scene. In addition, when the current display position of the virtual scene is adjusted based on the target change distance, the game camera can also be controlled to move to achieve the adjustment of the current display position of the virtual scene.

[0071] In an optional embodiment, the target change distance corresponding to the current display position of the virtual scene is determined according to the difference between the first distance and the second distance, such as Figure 6 As shown, this can be achieved by the following steps:

[0072] Step S610, determining a relative moving distance of the moving operation according to a difference between the first distance and the second distance;

[0073] Step S620 : determining a target change distance corresponding to the current display position of the virtual scene according to the relative movement distance of the movement operation and a preset distance change control parameter.

[0074] The relative movement distance of a move operation refers to the relative movement distance between the target object's head and hand in the real scene. For example, the difference between the first distance and the second distance can be directly used as the relative movement distance of the move operation, that is, S3 = |S1 - S2|, where S3 is the relative movement distance of the move operation, S1 represents the first distance, and S2 represents the second distance.

[0075] In addition, the direction of movement of the current display position of the virtual scene can also be controlled based on the positive or negative sign of the difference between the first distance and the second distance. For example, if the S1-S2 value is positive, the current display position of the virtual scene is controlled to move forward; if the S1-S2 value is negative, the current display position of the virtual scene is controlled to move backward. It should be noted that when controlling the current display position of the virtual scene to move forward or backward based on the positive or negative sign of the difference between the first distance and the second distance, the specific direction of movement can be set according to the daily behavior habits of the target object and is not specifically limited here.

[0076] The preset distance control variation parameter can be used to control the mapping relationship between the per-unit change in the relative movement distance of a move operation and the target movement distance corresponding to the virtual scene display position. For example, if the preset distance control variation parameter k is 100 and the relative movement distance of the move operation is 1 meter, the target change distance corresponding to the virtual scene display position can be 100 meters.

[0077] When determining the target change distance corresponding to the current display position of the virtual scene based on the relative moving distance of the moving operation and the preset distance change control parameter, the target change distance can be obtained by calculating S=S3×k, where S represents the target change distance, S3 represents the relative moving distance of the moving operation, and k represents the preset distance control change parameter.

[0078] It should be noted that the parameter value of the preset distance control change parameter k can be obtained through continuous user testing to ensure the visual comfort of the target object when the virtual scene display position changes.

[0079] Figure 6 The steps shown control the changing speed of the virtual scene display position based on the preset distance change control parameters, so that the virtual scene display position can break free from the limitations of the real scene space range, so as to realize the long-distance movement of the virtual scene display position, thereby enriching the applicable scenarios of VR applications.

[0080] In an optional embodiment, the target change distance corresponding to the current display position of the virtual scene is determined according to the relative moving distance of the moving operation and the preset distance change control parameter, such as Figure 7 As shown, this can be achieved by the following steps:

[0081] Step S710, adjusting the preset distance change control parameter according to the hand state of the target object;

[0082] Step S720 : determining a target change distance corresponding to the current display position of the virtual scene based on the relative movement distance of the movement operation and the adjusted preset distance change control parameter.

[0083] The hand state of the target object is used to control the adjustment scale of the preset distance change control parameter. The hand state of the target object includes but is not limited to the rotation angle of the target object's hand, the number of fingers extended by the target object, etc.

[0084] The hand rotation angle of the target object refers to the rotation angle of the hand of the target object from the time the display position adjustment event is triggered to the time the head and / or hand moves.

[0085] When adjusting the preset distance change control parameter based on the target object's hand rotation angle, the greater the target object's hand rotation angle, the greater the adjustment scale of the preset distance change control parameter. For example, if the target object's hand rotation angle is a, the preset change control parameter is k1, and the adjusted preset change control parameter is k1*a, then the target change distance S corresponding to the current display position of the virtual scene = S3*k1*a, where S represents the target change distance and S3 is the relative movement distance of the move operation. k1 can be a system-fixed value determined in advance through testing.

[0086] If the target object's hand rotates by an angle a1 relative to the base angle reference orientation when the display position adjustment event is triggered, and the target object's hand rotates by an angle a2 relative to the base angle reference orientation after the head and / or hand moves, the difference between a1 and a2 can be used as the target object's hand rotation angle, that is, a = |a1-a2|, so as to increase the preset distance change control parameter, thereby achieving a longer distance movement of the virtual scene display position. It should be noted that the base reference angle can be pre-configured to quantify the target object's hand rotation angle. For example, the orientation of the left hand with a fist facing downward can be used as the base reference angle. When the target object's left hand is clenched downward, the target object's hand is rotated by 0 degrees relative to the base angle reference orientation; when the target object's left hand is clenched to the right, the target object's hand is rotated by 90 degrees relative to the base angle reference orientation.

[0087] In addition, when adjusting the preset distance change control parameter by the hand rotation angle of the target object, the preset distance change control parameter can also be increased or decreased according to the positive or negative value of a1-a2. For example, if a1-a2 is a positive value, the value of k1*(a1-a2) can be used as the adjusted preset change control parameter to increase the preset distance change control parameter; if a1-a2 is a negative value, the value of k1*[1 / (a1-a2)] can be used as the adjusted preset change control parameter to decrease the preset distance change control parameter, thereby achieving free adjustment of the preset distance change control parameter.

[0088] When adjusting the preset distance change control parameter based on the number of fingers extended by the target object, the greater the number of fingers extended by the target object, the greater the adjustment scale. For example, if the number of fingers extended by the target object is b, the preset change control parameter is k2, and the adjusted preset change control parameter is k2*b, then the target change distance S corresponding to the current display position of the virtual scene = S3*k2*b, where S represents the target change distance and S3 is the relative movement distance of the move operation. k2 can be a system-fixed value determined in advance through testing.

[0089] Figure 7The steps shown realize the automatic adjustment of the preset distance change control parameters, and enhance the flexibility of controlling the movement of the virtual scene display position, so as to meet the diverse adjustment requirements of the target object.

[0090] also, Figure 8 A preferred display position adjustment method is provided, which may specifically include the following steps S810 to S850:

[0091] Step S810: If the somatosensory device detects that the target object's right hand is in a clenched fist, a display position adjustment event is triggered, a first position coordinate of the target object's head and a second position coordinate of the target object's hand are obtained, and a first distance between the target object's head and hand is obtained based on the first position coordinate of the target object's head and the second position coordinate of the target object's hand;

[0092] Step S820: In response to the movement operation of the target object's head and / or hand, obtaining third position coordinates of the target object's head and fourth position coordinates of the target object's hand, and obtaining a second distance between the target object's head and hand based on the third position coordinates of the target object's head and the fourth position coordinates of the target object's hand;

[0093] Step S830, determining a relative moving distance of the move operation according to the difference between the first distance and the second distance, and adjusting a preset distance change control parameter according to the left hand rotation angle of the target object;

[0094] Step S840 : determining a target change distance corresponding to the current display position of the virtual scene based on the relative movement distance of the movement operation and the adjusted preset distance change control parameter.
