[0024] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0025] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0026] The cursor control method, device, equipment and medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0027] Figure 1 : is a flow chart of a cursor control method provided in an embodiment of the present application. The cursor control method may include:

[0028] Step 101: Divide a first object operated by a user into a front side and at least one side side;

[0029] Step 102: determining a first side surface from at least one side surface according to the orientation of the user's first palm;

[0030] Step 103: Move the cursor to the first side surface.

[0031] The specific implementation of the above steps will be described in detail below.

[0032] In the embodiment of the present application, the first object operated by the user is divided into the front side and at least one side side; the first side side is determined from the at least one side side according to the orientation of the first palm of the user; and the cursor is moved to the first side side. In this way, the user can move the cursor to the side side of the object without rotating the object, and then operate the side side of the object, which can improve the interaction efficiency.

[0033] In some possible implementations of the embodiments of the present application, before step 101, the cursor control method provided by the embodiments of the present application may further include: identifying a first object, and executing step 101 when the first object is a three-dimensional object.

[0034] The embodiment of the present application does not limit the method used to identify the first object, and any available method can be applied to the embodiment of the present application. For example, the object can be identified using a three-dimensional recognition algorithm based on local features, a three-dimensional recognition algorithm based on global features, or a three-dimensional recognition algorithm based on deep learning.

[0035] In some possible implementations of the embodiments of the present application, when there are multiple objects, the object where the cursor is currently located can be taken as the first object, or the object that intersects with the user's line of sight can be taken as the first object, and the user's focus object can be taken as the first object.

[0036] In some possible implementations of the embodiments of the present application, step 101 may include: using curvature analysis to divide the surface of the first object into at least two areas; determining the area in the at least two areas where the angle between the normal vector and the user's line of sight is the largest as the front side; and determining each area in the at least two areas except the area corresponding to the front side as the side side.

[0037] In some possible implementations of the embodiments of the present application, when the surface of the first object is divided into at least two regions using curvature analysis, the surface curvature of each point on the surface of the first object can be calculated. When the points corresponding to the same surface curvature are not on the same straight line, the points corresponding to the same surface curvature are divided into one region; when the points corresponding to the same surface curvature are on the same straight line, the points corresponding to the same surface curvature are used as the boundary between the two regions.

[0038] After the surface of the first object is divided into at least two areas, the normal vector of each area can be calculated, and then the angle between the normal vector of each area and the direction of the user's line of sight is calculated. The area in the at least two areas where the angle between the normal vector and the user's line of sight is the largest is determined as the front side; each area in the direction area except the area corresponding to the front side is determined as a side side.

[0039] In some possible implementations of the embodiments of the present application, when the user's viewing angle changes, the front and side of the first object will also change accordingly. When the change in the user's viewing angle is greater than a preset angle threshold, the front and side of the first object are re-divided.

[0040] In some possible implementations of the embodiments of the present application, when the first object rotates, the front and side faces of the first object will also change accordingly. When the first object rotates, the front and side faces of the first object are re-divided.

[0041] In some possible implementations of the embodiment of the present application, the first palm in the embodiment of the present application is the palm of the hand whose gesture characteristics have changed.

[0042] In some possible implementations of the embodiments of the present application, it is possible that gesture changes occur in both hands of the user. Based on this, before step 102, the cursor control method provided in the embodiments of the present application may also include: when gesture changes occur in both hands of the user, taking the palm of the hand with the largest change in gesture features as the first palm.

[0043] In some possible implementations of the embodiments of the present application, the change amount of the gesture feature in the embodiments of the present application can be measured by the similarity between the gesture feature before the gesture changes and the gesture feature after the gesture changes. The greater the similarity, the smaller the change amount of the gesture feature, and the smaller the similarity, the greater the change amount of the gesture feature. Among them, the similarity between the gesture feature before the gesture changes and the gesture feature after the gesture changes can be obtained by calculating the cosine similarity of the feature vector of the gesture feature before the gesture changes and the feature vector of the gesture feature after the gesture changes.

[0044] In some possible implementations of the embodiments of the present application, step 102 may include: calculating a first angle between the orientation of the first palm and the normal vector of each side surface; and determining a first side surface from at least one side surface according to the first angle.

[0045] In some possible implementations of the embodiments of the present application, the cosine value of the angle between the orientation of the first palm and the normal vector of the side can be calculated through the orientation of the first palm and the normal vector of the side, and then the degree of the angle between the orientation of the first palm and the normal vector of the side can be obtained through the cosine value.

[0046] In some possible implementations of the embodiments of the present application, when determining the first side surface from at least one side surface based on the first angle, the side surface corresponding to the first angle greater than or equal to the first angle and less than or equal to 180° in at least one side surface can be determined as the first side surface.

[0047] In some possible implementations of the embodiments of the present application, the first angle in the embodiments of the present application may be set according to actual needs.

[0048] In some possible implementations of the embodiments of the present application, the side corresponding to the largest first angle among the at least one side may be determined as the first side. When there are at least two side corresponding to the largest first angle, any one of the at least two side corresponding to the largest first angle may be used as the first side; or, the side selected by the user from the at least two side corresponding to the largest first angle may be used as the first side.

[0049] In some possible implementations of the embodiments of the present application, in step 103, when the cursor is moved to the first side surface, the cursor may be rotated around the central axis of the first object so that the cursor is moved to the first side surface. When the cursor is rotated around the central axis of the first object, the cursor may be moved to the first side surface by changing the amount of cursor rotation. After the cursor is moved to the first side surface, the cursor is perpendicular to the normal vector of the first side surface.

[0050] In some possible implementations of the embodiments of the present application, the cursor control method provided by the embodiments of the present application may also include: determining a second displacement of the cursor on the first side according to the first displacement of the user's finger; and moving the cursor on the first side according to the second displacement.

[0051] The embodiments of the present application do not limit the method used to obtain the displacement of the user's fingers in the actual space. Any available method can be applied to the embodiments of the present application. For example, using a camera for collection. For another example, when the user wears data gloves, the displacement of the fingers sent by the data gloves can be directly received.

[0052] In some possible implementations of the embodiments of the present application, when determining the second displacement of the cursor on the first side according to the first displacement of the user's finger, the second displacement can be determined according to the mapping ratio of the displacement of the cursor on the first side to the finger displacement and the first displacement.

[0053] In some possible implementations of the embodiments of the present application, the mapping ratio of the displacement of the cursor on different sides to the displacement of the finger can be determined according to the size of the side and the range of finger movement. The embodiments of the present application do not elaborate on the process of determining the mapping ratio of the displacement of the cursor on different sides to the displacement of the finger according to the size of the side and the range of finger movement. For example, for a certain side, first calculate the second distance that the cursor moves on the front side when the finger moves the first distance, and calculate the third movement distance of the cursor on the side side when the finger moves the first distance based on the second distance that the cursor moves on the front side and the angle between the side side and the front side, and then obtain the mapping ratio of the displacement of the cursor on the side side to the displacement of the finger.

[0054] Exemplarily, assuming that the displacement of the finger is x, and the mapping ratio of the displacement of the cursor on the side to the displacement of the finger is d, the displacement of the cursor on the side is d*x.

[0055] After the displacement of the cursor on the side is determined, the moving direction of the cursor on the side is determined according to the moving direction of the user's finger, and then the cursor is moved on the side in the determined moving direction of the cursor on the side by a second displacement.

[0056] The cursor control method provided by the embodiment of the present application is described below with reference to specific examples. Figures 2 to 4 shown.

[0057] exist Figure 2 In , the object is divided into the front and two sides, the two sides are side A and side B. Figure 3In , the side that the user is going to operate is determined by the direction of the user's palm, and the angles between the user's palm normal vector and the normal vectors of side A and side B are calculated. The angle between the user's palm normal vector and the normal vector of side B is greater than the angle between the user's palm normal vector and the normal vector of side A. Side B is determined as the side that the user is going to operate. By modifying the cursor rotation amount, the cursor is moved from the front to the corresponding position on side B. The direction and distance of the user's index finger tip movement are obtained. Figure 4 It is represented by E in the figure and mapped to the side B, recorded as vector K. Vector K is multiplied by the mapping ratio u corresponding to the side B to obtain vector uK. The vector uK is the displacement of the cursor. The cursor is moved by vector uK, that is, the cursor is moved to the position on the side B where the user expects to operate.
