An Omnidirectional Motion Device Based on Virtual Reality

Abstract

The invention relates to an omnidirectional motion device based on virtual reality, comprising: a platform, a VR helmet, and several spheres arranged at the bottom of the platform; at least one bias magnet is arranged on the outside of the sphere; The motion unit includes at least one cavity and several coils. The sphere can rotate in the cavity, and several coils surround the outside of the cavity. There are multiple coils on the outside of any sphere, and the magnetic field generated by the coil can be energized. Control the rotation of the sphere; the platform is a flexible surface structure, and there are several sensors on the platform, which are used to detect the moving direction and moving speed of the user on the platform. There is a base at the bottom of the platform; the rotation of the sphere can drive the platform to move. The moving direction is opposite to that of the user, and the moving speed is the same; the VR helmet is used to display the virtual scene image, and the user moves according to the 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.
