detailed description

The technical solution of the method and system for implementing the gesture control based on the gesture container according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

In the embodiment of the present application, the gesture-non-contact virtual control is used to display the dice container model and/or the dice model displayed on the interface, and the physical engine (for example, Nvidia's PhysX, etc., which uses the CPU, GPU, and the like to accurately simulate the object. The simulation effects of gravity, friction, collision, etc. in the three-dimensional space) simulate the collision between the scorpion models and the scorpion container model and the scorpion model, realizing the process of the game participants shaking the scorpion container with the gesture virtual control, bringing the lifelike The interactive experience, and in the simulation, according to the number of collisions between the scorpion models and between the scorpion container model and the scorpion model, the number of points of the scorpion model is automatically read and counted, and the randomness of the accurate and fair control results is achieved.

Specifically, the method for controlling a dice based on gestures provided by the embodiment of the present application, as shown in FIG. 1 , includes the following steps:

Step S11: importing the dice container model and the dice model;

Before importing the dice container model and the dice model, first establish the dice container model and the dice model; and set the properties of the dice container model and the dice model; the setting properties include but are not limited to setting the model material and adding the collider, etc. .

Specifically, a common one to six point dice is used as an example to establish a model, but other patterns are not excluded. The embodiment of the present application is not limited; the dice model is generally a regular hexahedron, and may also have rounded corners. The shape of the tweezers container model may be a closed container or other shape, including an open container that is not sealed on one side, or a fully enclosed container.

After setting up the scorpion container model and the scorpion model, set the scorpion container model and the scorpion model to the Rigid body and set their rigid body properties, including but not limited to weight, resistance, angular resistance, gravity. Influencing, etc.; adding a first collider to the dice container model, adding a second collider to the dice model, setting the physical material of each part of the dice container model, and setting the material of the dice model because of the surface of the different physical materials Collision and friction will have different rebound and friction effects.

Step S12: receiving hand motion information; the hand motion information is spatial three-dimensional coordinates and speed information of the palm or the arm;

The movement information of the hand (palm or arm) is obtained by setting the model of the dice container The depth sensor around the display interface is implemented; the current depth sensor can obtain the three-dimensional coordinates and speed of the motion space of the hand, the arm, etc., taking the kinect sensor as an example, which can be obtained at a frequency of 30-60 frames per second. The information of the hand, and the LeapMotion sensor can be acquired at a frequency of 1000 frames per second, which can fully meet the refresh frequency requirements of tens of frames in 3D simulation.

As shown in FIG. 4 , the depth sensor 1 is placed on the front end of the display interface 2 , and the sensible range forms an interaction space in front of the display interface to sense the palm or the arm, and the game participant performs the hand operation in the interaction space. At the same time, the palm or arm position and velocity information can be sensed by the depth sensor.

Step S13: updating the position of the die container model on the display interface according to the hand motion information.

The depth sensor acquires the spatial three-dimensional coordinates and velocity information of the palm or arm in three-dimensional space. The velocity information includes the velocity and velocity directions. When the motion of the palm or arm in the three-dimensional space is mapped to the display interface, the mapping can be mapped to two. The translational motion in the dimensional coordinate system can also be mapped into motion in another three-dimensional coordinate system. This scheme does not limit. Preferably, the three-dimensional display of the palm or arm is mapped to the motion in the other three-dimensional coordinate system.

Specifically, the position of the dice container model on the display interface can be updated in two ways:

The first way is to determine whether the speed of the palm or the arm is greater than a preset speed; if so, determining the displacement and the speed of the movement of the forceps container model on the display interface according to the hand information; and based on the displacement And the speed of the movement updates the position of the dice container model on the display interface.

The spatial three-dimensional coordinates of the palm or arm acquired by the depth sensor are mapped to the three-dimensional coordinate system of the display interface, and the palm or the arm is calculated in the three-dimensional coordinate system of the interactive interface according to the change of the coordinates of the palm or the arm in the spatial three-dimensional coordinate system. Displacement and displacement velocity, and correlating the displacement and displacement velocity with the forceps container model, so that the forceps container model changes position according to the displacement and displacement speed, thereby converting the movement of the hand into the movement of the forceps container model, realizing The effect of virtual control of the dice container model with gestures.

The second way is: determining the swing amplitude of the palm or the arm according to the hand information; and updating the tilting amplitude of the forceps container model on the display interface based on the swing amplitude.

In the above first mode, what can be achieved is the effect of the scorpion container model shaking with the overall gesture. The displacement and speed of the sway depends on the displacement and speed of the palm or arm shaking in three dimensions; in the second way, the effect of the scorpion container model with the bottom (or top) as the axis swaying, the depth sensor The obtained three-dimensional coordinates of the palm or arm are mapped to the three-dimensional coordinate system of the display interface, and the amplitude of the palm or arm in the three-dimensional coordinate system of the display interface is calculated according to the change of the coordinates of the palm or the arm in the spatial three-dimensional coordinate system. And correlating the magnitude with the tilting amplitude of the braid container model (with the bottom or top as the axis), causing the forceps container model to sway according to the tilting amplitude, thereby transforming the hand motion into the forceps container model. Movement, the effect of virtual control of the dice container model with gestures.

Through the above means, the depth sensor is used to acquire the hand movement information of the game participant in the three-dimensional space, and the movement of the hand is associated with the movement of the dice container model of the display interface to realize the dice container of the virtual control display interface of the game participant. Game participants really participate in the game of shaking the dice, increasing their participation in the game.

Further, after the gesture virtual control of the movement of the dice container model, the method provided by the embodiment of the present application can also combine the physical engine to realize the collision and friction between the dice model and the dice container model, and the collision and friction between the dice models. , simulating the movement of the dice in the dice container, thus achieving the entire process of shaking the dice game. That is, the physics engine is invoked to simulate the collision and friction between the die container model and the die model, and the collision and friction between the die models; specifically, as shown in FIG. 2, the following steps are included:

Step S14: Calling the physics engine

Step S15: determining whether collision and friction occur between the die container model and the die model, and between the die models; if yes,

Step S16: Simulating the collision and friction.

The material of the scorpion container model can be transparent or opaque, or it can be opaque during the shaking of the game participants, and transparent when displaying the details of the scorpion model after the shaking.

The amplitude and speed of the swing of the player's hand determines the amplitude and speed of the swing of the dice container model on the display interface.

The physics engine counts collisions and frictions while simulating collisions and frictions, and updates the results of the counts into counters. It automatically simulates the collision between the rafters and the rafters and the rafters in conjunction with the properties of the model. Friction, making the scorpion model randomly touch in the scorpion container model Collision and friction, simulate the movement of the dice in reality; thus, the motion simulation of shaking the dice container in reality becomes the animation operation of the display interface, so that any game participants do not directly contact the dice and dice containers, realizing the fairness and fairness of the game process. And make the interactive experience of game participants more direct.

In order to ensure that the game process is more fair and equitable, the physics engine can be invoked to simulate the collision and friction between the die container model and the die model, and the collision and friction between the die models, for each collision and Friction adds a collision random variable to randomly flip the dice model. Since the system can not only influence the result through the collision and friction effect of the physics engine and the model material, it can also add random variables such as flipping and moving to influence the result (such as the flip angle, rebound speed, etc.) at any time during the movement of the die model. This can further strengthen the randomness of the dice model points and eliminate the artificial control factors.

When the game participant wants to stop the shaking of the dice container action, the virtual gesture control can be stopped, or the speed of the hand motion can be slowed down, as in the actual operation; thus, the method provided by the embodiment of the present application proceeds to the following steps:

Step S17: determining whether the speed of the palm or the arm is less than a preset speed;

If yes, step S18: stopping the movement of the die container model;

Step S19: After the dice model is stationary, the number of points of the dice model facing upward is counted.

When judging whether to end the action of shaking the dice model, it may be that the movement speed of the palm or the arm in a certain period of time is less than the threshold set in advance, or the collision between the dice container model and the dice model, and the dice model collide with each other. The number of times of friction and the number of frictions is greater than a threshold set in advance. If the condition is met, the motion of the rafter model is stopped, and the simulation of the physics engine is further stopped, and the number of points of all the scorpion models facing upward is counted after the scorpion model is stationary.

Of course, during the simulation of the shaking of the dice, that is, when the physics engine is invoked to simulate the collision and friction between the dice container model and the dice model, and the collision and friction between the dice models, the dice model can be The simulation of the random collision between the dice model and the dice container model (when the material of the dice container model is transparent) can also display the random state of the dice after the shaking of the dice container is completed (in the process of simulating the dice container, setting The material of the scorpion container model is opaque. After the game is over, the material of the scorpion container model is set to be transparent, showing the random state of the scorpion model. The random state can be random and non-referenced (ie, not related to the actual number of points). ), just to demonstrate the improvement of game simulation, or the number of points on the calculated side of the dice model After that, the display state of the die model is simulated according to the number of points, so that the number of displayed points coincides with the calculated number of points.

In the existing dice game, it is impossible for the game participants to intuitively see the process result of shaking the dice container, and can quickly and accurately input the result into the system for statistical effect. In the embodiment of the present application, after a plurality of game participants respectively perform the virtual control of the action of rolling the dice, the results of all the game participants' dice are also counted and compared, and the final outcome is given.

This allows the game participants to realize the operation of shaking the dice container by the virtual control of the gesture. At the same time, when the action of shaking the dice container is finished, the point result is immediately known, and the result of the victory and the negative is not required to be observed and self-recorded, which further improves the result. User experience.

More preferably, when the physical engine is invoked to simulate the collision and friction between the die container model and the die model, and the collision and friction between the die models, the sound effects of collision and friction are played, and the shaking is further improved. The fidelity of the dice; even with lighting effects and background music, mobilize the interest and enthusiasm of the game participants.

In association with the movement of the scorpion container model, the action of using the gesture virtual control to shake the scorpion container is realized, so that the game participants actually participate in the process of rolling the dice, thereby improving the user experience.
