Omni-directional movement device based on virtual reality

Abstract

The invention relates to an omni-directional movement device based on virtual reality. The omni-directional movement device comprises a platform, a VR helmet and a plurality of spheres arranged at thebottom of the platform. At least one bias magnet is arranged on the outer side of the ball body; a movement unit matched with the balls is arranged at the bottom of the platform and comprises at least one accommodating cavity and a plurality of coils, the balls can rotate in the accommodating cavity, the coils surround the outer side of the accommodating cavity, a plurality of coils are arrangedon the outer side of any ball, and a magnetic field generated by electrifying the coils can control the balls to rotate; the platform is of a flexible surface structure, a plurality of sensors are arranged on the platform and used for detecting the moving direction and the moving speed of a user on the platform, and a base is arranged at the bottom of the platform. The ball rotates to drive the platform to move, the moving direction of the platform is opposite to that of a user, and the moving speed is the same; the VR helmet is used for displaying a virtual scene image, and a user moves according to a virtual scene.

Description

technical field [0001] The invention relates to an omnidirectional exercise device, in particular to an omnidirectional exercise device based on virtual reality. Background technique [0002] For the application of virtual reality, the user moves virtually in the application or in the game. Under the common impression, the user wears a VR helmet in order to simulate the game environment. With this helmet, the user obtains visual and auditory reproduction Game environment and game flow. In these VR applications, it is necessary for players to move virtually along any horizontal spatial direction and in all directions, such as walking or run. [0003] The traditional universal motion device directly drives the sphere to move through the drive mechanism. The control accuracy of the drive mechanism is difficult to guarantee, and the offset of the sphere is not controlled by changing the current through the bias magnet under the action of the magnetic field. In addition, it is ...

Problems solved by technology

[0003] The traditional universal motion device directly drives the sphere to move through the drive mechanism. The control accuracy of the drive mechanism is difficult to guarantee, and the offset of the sphere is not controlled by changing the current through the bias magnet under the action of the magnetic field.

In addition, it is also impossible to control the sphere to move and rotate sequentially along the predetermined trajectory by setting the arrangement of the coils, such as according to a circular trajectory, a square trajectory arrangement or a diamond trajectory arrangement, and the control effect is poor.
