The system architecture may not include a network when the electronic device on which the gesture-based control method for simulating a target body movement trajectory operates does not need to perform data transmission with other electronic devices.

FIG. 2 illustrates a flow 200 of one embodiment of a method for gesture-based control of a simulated target volume motion trajectory according to the present application. The method for controlling the motion trail of the simulated target body based on the gesture can be suitable for an execution main body with an image display function. The execution subject can simulate a moving object such as a car, a bicycle, a person, etc. on the electronic map by the simulation object. The process 200 includes the following steps:

step 201, in response to the detection of the gesture operation of the user, determining a gesture offset of the user gesture relative to the reference point according to the gesture operation.

In this embodiment, an executing subject (for example, a desktop computer) running the method for controlling the motion trajectory of the simulated target body based on the gesture may first detect a gesture operation of a user, and when the gesture operation is detected, determine a gesture offset of the user gesture with respect to a reference point according to the detected gesture operation.

A gesture is a hand gesture. The gesture may be a movement of the entire hand or a movement of a finger. In practice, the executing body may detect the user gesture by at least one of detecting a handle, a mouse, or a gesture detecting control, but not limited thereto. When the execution main body detects a user gesture through the detection handle, the detection handle may be a part of the execution main body, at this time, the execution main body is hardware or a combination of hardware and software, and the detection handle may also be an external device of the execution main body, at this time, if the detection main body is hardware, the detection handle may be connected to the execution main body through hardware, and if the detection main body is software, the detection handle may be connected to hardware to which the execution main body operates. When the execution main body detects the gesture operation of the user through the gesture detection control, the touch operation of the screen can be detected through the user, and the movement of a mouse pointer related to the movement of the mouse on the screen gesture detection control can also be detected. Alternatively, the detection handle may be any physical component such as a steering wheel, a game pad, etc. that can be used to input a gesture change signal. This is not a specific limitation in the present application.

The execution body can measure the change of the user gesture through the gesture offset. The execution main body may preset a fixed reference point for acquiring a gesture offset, for example, the reference point is a center point of the detection handle, and the execution main body may also acquire a starting point when the user performs a gesture operation as the reference point. The present application is not limited to this.

In some optional implementations of this embodiment, the gesture offset includes a distance, an angle, and a change time of the user gesture from the reference point. In one gesture operation, the execution main body can acquire one gesture offset, and can also acquire multiple gesture offsets according to a preset time interval. When the gesture offset is acquired for multiple times according to the preset time interval, the reference point can also be changed differently, the reference point acquired by the first word is the gesture operation starting point, and the reference point acquired each time is the gesture operation ending point acquired last time. The distance between the gesture of the user and the reference point can be the distance between the gesture operation ending point and the reference point. The angle between the user gesture and the reference point is used to indicate the moving direction of the user gesture, and may be described by using a coordinate system with the reference point as an origin (for example, a planar coordinate system with the reference point as an origin and left-right, up-down and left-right coordinate axes on the user gesture collection surface) as a reference system, such as an angle of 45 degrees with respect to the right coordinate axis. The time of change of the user gesture may be used to measure the speed at which the user gesture changes, along with the distance of the user gesture from a reference point. The greater the distance of the user gesture from the reference point within the same change time, or the shorter the change time within the same distance, the greater the speed of change of the user gesture.

Step 202, mapping the gesture offset to a position change parameter of the simulation target body according to a preset mapping rule.

In this embodiment, the execution main body may store a predetermined mapping rule, and in this step, the execution main body may then map the gesture offset to the position change parameter of the simulation target body according to the predetermined mapping rule.

The position change parameter of the simulation target body may be a parameter for expressing a change to be made by the simulation target body. For example, the position change parameter may include, but is not limited to, at least one of a direction of change, a speed of change, a distance of change, and the like. Wherein: the changing direction can be the direction of the change of the simulation target body compared with the current direction or the changed direction; the change speed can be the speed after the simulation target body changes, or the speed when the movement speed of the simulation target body changes, namely the acceleration; the varying distance may be a distance that simulates movement of the target.

It can be understood that the gesture operation is used for controlling the motion trajectory of the simulation target, but the gesture operation is not used for completely replacing the simulation target in a coordinate system for real-time simulation, and therefore, after the gesture offset is acquired by the execution main body, the gesture offset and the position change parameter of the simulation target need to be converted. In practice, the scaling may be performed according to a predetermined mapping rule. The predetermined mapping rule may be, for example, that the gesture offset of the user gesture with respect to the reference point is converted equally or proportionally to a position change parameter of the simulated object.

It should be noted that the position change parameter of the simulation target body may be a reference point for simulating the position change of the target body at the start point of the movement locus of the simulation target body, may be a reference point for simulating the position change of the target body at the origin of the coordinate system in which the movement locus of the simulation target body is located, or may be a reference point for simulating the position change of the target body at the current position of the simulation target body. To simplify the calculation and reduce the data processing amount, in some implementations, the execution subject may use the current position of the simulation target as a reference point for the change in the position of the simulation target.

In some optional implementations of this embodiment, the gesture offset includes a distance, an angle, and a change time between the user gesture and the reference point, and the position change parameter includes a change direction, a change speed, and a change distance, where the predetermined mapping rule may include: determining a change direction in the position change parameter according to an angle between the user gesture and the reference point, for example, the change direction in the position change parameter may be consistent with the angle between the user gesture and the reference point; determining a variation distance in the position variation parameter according to a distance between the user gesture and the reference point, for example, the variation distance in the position variation parameter may be positively correlated with the distance between the user gesture and the reference point; the speed of change in the location change parameter is determined from the distance and time of change of the gesture from the reference point, e.g., the speed of change in the location change parameter may be positively correlated to a quotient of the distance and time of change of the gesture from the reference point.

And step 203, acquiring the current positioning information of the simulation target body.

In this embodiment, the executing body may further obtain current positioning information of the simulation target body. Wherein the current positioning information of the simulated target volume may include, but is not limited to, at least one of: coordinates, angle, speed. The coordinates can be longitude and latitude coordinate values of the simulation target body in a coordinate system, such as an electronic map coordinate system; the angle can be an angle formed by a connecting line of the simulation target body and the origin of the coordinate system and a coordinate axis; the speed may be a moving speed of the simulated object in the coordinate system, which may be represented by a speed converted into a real situation (for example, a vehicle speed of 45 kilometers per hour), or may be represented by an actual moving distance in the electronic map (for example, 5 pixels per second).

And step 204, combining the current positioning information of the simulated target body and the position change parameters to determine the changed positioning data of the simulated target body.

In this embodiment, the executing body may further determine the positioning data after the change of the simulated object by combining the current positioning information of the simulated object and the position change parameter. It will be appreciated that the changed positioning data of the simulated object may correspond to the current positioning information of the simulated object in step 203, and may include parameters corresponding to the current positioning information to determine the changed movement status and/or position status of the simulated object.

In some implementations, if the direction of change in the position change parameter is a direction after the change of the simulated object, the execution subject may directly determine the direction of change as a direction in the simulated object positioning data. In other implementations, the direction of change may be a direction in which the simulated object changes compared to the current direction, and the execution subject may superimpose the angle and the speed of change in the current positioning information of the simulated object as the direction in the simulated object positioning data. The variation speed can also be determined in the same way, and is not described in detail here. For the coordinates in the positioning data after the position change, the execution main body can be obtained by decomposing the coordinate axis according to the change direction and the change distance and superposing the coordinate axis with the current coordinates of the simulation target body. It will be appreciated that some alternative implementations are listed in this example, but they are not exhaustive, and they do not cover all the various cases shown.

And step 205, updating and positioning the simulated target body according to the positioning data after the position change so as to control the motion track of the simulated target body.

In this embodiment, the executing body may further update and position the simulation target according to the positioning data after the position change, so as to control the motion trajectory of the simulation target. As previously described, the positioning may include positioning one or more of the speed, direction, and coordinates of the simulated object travel. In some implementations, the execution subject may further display the updated positioning information and the updated motion trajectory of the simulation target through a screen.

Referring to fig. 3a and 3b, fig. 3a and 3b show an application scenario of the method for controlling a motion trajectory of a simulated object based on a gesture according to the embodiment of the present application. In the application scene, the electronic device executing the method for controlling the motion trail of the simulated target body based on the gesture at least comprises a touch screen and a processor, wherein the processor can store a program for operating the method for controlling the motion trail of the simulated target body based on the gesture, the touch screen can display the motion trail of the simulated target body in the electronic map, and a man-machine interaction medium can be provided for acquiring the user gesture through the gesture detection control. As shown in fig. 3a, the simulated object 311 is located in the electronic map 310. Fig. 3b shows a gesture detection control 320, a user gesture 322, in the touch screen. In this application scenario, the reference point for gesture capture is the center point 321 of the gesture detection control 320.

First, a user slides the surface of the touch screen with a hand, the gesture detection control 320 determines an initial point of the user contacting the touch screen as a central point 321 of the gesture detection control 320 and displays the initial point on the touch screen, the gesture detection control 320 automatically detects a user gesture operation, and the electronic device may determine a gesture offset (e.g., a distance, an angle, a change time, etc. of the user gesture 322 from the central point 321) according to the user gesture operation. Then, the electronic device may map the gesture offset to a position change parameter of the simulation object 311 in the electronic map 310 according to a predetermined mapping rule. Then, the electronic device may obtain the current positioning information (such as coordinates, angle, speed, etc.) of the simulation object 311 in the electronic map 310. Further, the electronic device may combine the current positioning information of the simulation object 311 and the position change parameter to determine the positioning data of the simulation object 311 after the change in the electronic map 310. Then, the electronic device may further update the positioning of the simulation object 311 according to the positioning data after the position change and display the updated positioning data in the electronic map 310 to control the motion trajectory of the simulation object 311.

Therefore, the method for controlling the motion trail of the simulated target body based on the gesture controls the simulated target body in the electronic map based on the gesture, and the field drive test of real equipment is not needed, so that the effectiveness of checking the navigation performance of the electronic map can be improved.

With further reference to fig. 4, as an implementation of the method for controlling a motion trajectory of a simulated object based on a gesture, the present application provides an embodiment of an apparatus for controlling a motion trajectory of a simulated object based on a gesture, where the embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 2.

As shown in fig. 4, the apparatus 400 for controlling the motion trajectory of the simulated target based on the gesture of the present embodiment includes: a determination module 401, a mapping module 402, an acquisition module 403, a combination module 404, and an update module 405. The determining module 401 may be configured to, in response to detecting the gesture operation of the user, determine a gesture offset of the gesture of the user relative to the reference point according to the gesture operation; the mapping module 402 may be configured to map the gesture offset to a position change parameter of the simulated target volume according to a predetermined mapping rule; the obtaining module 403 may be configured to obtain current positioning information of the simulation target; the combining module 404 may be configured to combine the current positioning information of the simulated object with the position change parameter to determine the changed positioning data of the simulated object; the update module 405 may be configured to update the position of the simulated object according to the position-changed positioning data to control the motion trajectory of the simulated object.

In this embodiment, the determining module 401 may first determine, in response to detecting the gesture operation of the user, a gesture offset of the gesture of the user with respect to the reference point according to the gesture operation. The gesture offset may be used to measure the change in the user's gesture. In some implementations, the gesture offset may include one or more of a distance, an angle, a time of change of the user gesture from a reference point.

In this embodiment, the mapping module 402 may store a predetermined mapping rule thereon, and the mapping module 402 may then map the gesture offset to the position change parameter of the simulation target body according to the predetermined mapping rule. The position change parameter of the simulation target body may be a parameter for expressing a change to be made by the simulation target body. For example, the location change parameter may include, but is not limited to, at least one of a direction of change, a speed of change, a distance of change, and the like. In some optional implementations of this embodiment, the gesture offset includes a distance, an angle, and a change time between the user gesture and the reference point, and the position change parameter includes a change direction, a change speed, and a change distance, where the predetermined mapping rule may include: determining a change direction in the position change parameter according to the angle between the user gesture and the reference point; determining a variation distance in the position variation parameter according to the distance between the user gesture and the reference point; and determining the change speed in the position change parameters according to the distance between the gesture and the datum point and the change time.

In this embodiment, the obtaining module 403 may then obtain the current positioning information of the simulated target volume. Wherein the current positioning information of the simulated target volume may include, but is not limited to, at least one of: coordinates, angle, speed.

In this embodiment, the combining module 404 may then combine the current positioning information of the simulated object and the position change parameter to determine the changed positioning data of the simulated object. It is understood that the positioning data of the simulated object after being changed may correspond to the current positioning information of the simulated object obtained by the obtaining module 403, which may include parameters corresponding to the current positioning information for determining the changed motion state and/or position state of the simulated object.

In this embodiment, the updating module 405 may then update the position of the simulated object according to the positioning data after the position change, so as to control the motion trajectory of the simulated object. In some implementations, the gesture-based apparatus 400 for controlling the movement trace of the simulation target may further include a display module for displaying the updated positioning information and the movement trace of the simulation target through a screen.

It is noted that the modules described in the device 400 for controlling the motion trail of the simulated target body based on the gesture correspond to the steps of the method described with reference to fig. 2. Thus, the operations and features described above for the method are equally applicable to the apparatus 400 and the modules or units included therein, and are not described in detail here.
