Description

VR grabbing action optimization method and device

Technical Field

The invention relates to the technical field of virtual reality application, in particular to a method and a device for optimizing VR grabbing actions.

Background

In existing virtual reality applications, such as the Oculus official case, the way to implement the grabbing action is generally by making a target gesture, directly switching to the target gesture when needed, or playing the target gesture in an animation manner.

In the grabbing actions of the two modes, if the experiencer plays games, such as shooting games, the attention of the experiencer is not focused on the grabbing process, but the experiencer observes whether enemies exist in the surrounding environment in a whole body and mind manner, and the influence on the experience effect of the experiencer is small. And if the experiencer experiences related projects, for example, the experiencer experiences the converter spot inspection projects, that is, the virtual reality device captures an operation tool in a virtual scene to simulate daily spot inspection work of the converter workshop device. At this time, the attention of the experiencer is focused on the gestures in the virtual scene, and the grabbing action processes in the above two ways can make the experiencer feel obtrusive.

In summary, the existing VR grabbing action process lacks authenticity, resulting in poor user experience.

Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

To facilitate understanding of the embodiment, a detailed description is first given of an optimization method for VR capture according to the embodiment of the present invention.

The first embodiment is as follows:

a method for optimizing VR grabbing actions, referring to fig. 1, the method includes:

s101, creating a hand model to execute a grabbing gesture of a grabbing action, wherein the grabbing gesture comprises the following steps: an initial gesture at the moment of starting the grabbing action and a target gesture at the moment of finishing the grabbing action;

in the embodiment of the present invention, the creating process is performed in a game development tool, and specifically, the game development tool used in the embodiment of the present invention is a unity3d engine. The grabbing gestures are pre-made, and after the grabbing gestures are made, the grabbing gestures can be directly obtained and used as resources when used every time.

S102, carrying out parameter configuration on the grabbing gesture based on a configuration instruction sent by a developer so as to enable a game development tool and a motion capture handle to be matched for use;

after the game development tool obtains the grabbing gesture, parameter configuration needs to be performed on the grabbing gesture, and after the configuration is completed, the game development tool and the motion capture handle can be used in a matched mode, namely, the motion capture handle can control the grabbing gesture in the game development tool to execute grabbing action.

S103, based on the triggering of the motion capture handle, the game development tool carries out interpolation operation on the initial gesture and the target gesture through an interpolation algorithm to obtain an intermediate gesture between the initial gesture and the target gesture;

after the configuration is completed and a certain action is triggered by the action capture handle, the game development tool carries out interpolation operation on the initial gesture and the target gesture through an interpolation algorithm to obtain an intermediate gesture between the initial gesture and the target gesture.

And S104, controlling the hand model to sequentially execute grabbing actions according to the position data indicated by the initial gesture, the intermediate gesture and the target gesture, so that the hand model smoothly moves from the initial gesture to the target gesture.

After the intermediate gesture is obtained, the game development tool can control the hand models to sequentially execute the grabbing action according to the initial gesture, the intermediate gesture and the position data indicated by the target gesture, so that the hand models smoothly move to the target gesture from the initial gesture.

It should be noted that the above processes are all completed in the game development tool.

In the existing VR grabbing action process, a target gesture is generally made, the target gesture is directly switched to when needed, or the target gesture is played in an animation mode, and the grabbing actions of the two modes lack authenticity. Compared with the existing VR grabbing action process, the VR grabbing action optimization method comprises the steps of firstly creating an initial gesture and a target gesture for executing grabbing actions, then configuring parameters of the grabbing gestures to enable a game development tool and a motion capture handle to be matched for use, further, based on triggering of the motion capture handle, carrying out difference operation on the initial gesture and the target gesture by the game development tool through an interpolation algorithm to obtain an intermediate gesture, and finally controlling hand models to sequentially execute the grabbing actions according to position data indicated by the initial gesture, the intermediate gesture and the target gesture to enable the hand models to smoothly move to the target gesture from the initial gesture. According to the VR grabbing action optimization method, the initial gesture can be smoothly moved to the target gesture through the intermediate gesture in the grabbing action process in a mode of calculating the intermediate gesture, so that the whole grabbing action is more real, the user experience is improved, and the technical problem that the existing VR grabbing action process is lack of reality is solved.

In the embodiment of the invention, the grabbing gesture for creating the hand model to execute the grabbing action is different from the creating mode in the prior art, when the grabbing gesture is created, an artist generally makes the gesture, the process is complicated, the labor is wasted, and the reality of the made grabbing gesture is poor. In an alternative embodiment, creating a grip gesture for the hand model to perform the grip action includes: the method comprises the following steps:

s201, controlling a hand model in a game development tool to execute corresponding actions based on a first action instruction sent by a developer through an action capture handle so as to determine a preset capture action;

specifically, the developer controls the motion capture handle to move, so that the hand model in the virtual scene also executes corresponding movement, when the movement obtains a required gesture, the pause button can be clicked, and the required gesture stops in the virtual scene to obtain a preset capture action.

S202, reserving the preset grabbing action to obtain the gesture of the grabbing action.

After the preset grabbing action is obtained, the unit 3d includes a preset reserving function, so that the preset grabbing action can be reserved, the gesture of the grabbing action is obtained, and the gesture is stored as a resource.

After the parameter configuration is performed on the grabbing gesture, the interpolation operation may be performed on the initial gesture and the target gesture through the interpolation algorithm based on the trigger of the motion capture handle, and in an optional embodiment, referring to fig. 3, the interpolation operation performed on the initial gesture and the target gesture through the interpolation algorithm based on the trigger of the motion capture handle includes the following steps:

s301, receiving a second motion instruction sent by a motion capture handle;

the second action instruction is an action instruction when a relevant operation is performed in the virtual scene, such as: and the grabbing operation tool carries out point inspection operation on the converter workshop equipment.

S302, after the second action instruction is received, calculating the position data of the initial gesture and the position data of the target gesture through an interpolation algorithm to obtain the position data of the intermediate gesture between the initial gesture and the target gesture.

After the second action instruction is received, the position data of the initial gesture and the position data of the target gesture can be calculated through an interpolation algorithm, and the position data of the intermediate gesture is obtained.

and controlling the hand model to sequentially reach the positions indicated by the initial gesture, the intermediate gesture and the target gesture so as to execute the grabbing action.
