Simulation steering treadmill for VR (virtual reality) equipment

Abstract

A simulation steering treadmill for VR equipment comprises a running belt, the running belt can be installed between two first sliding rails in a front-back moving mode, the first sliding rails are installed on a rotating disc driven by a rotating motor, and the original point position of the running belt is located over the circle center of the rotating disc; the steering treadmill further comprises a steering ring, and a plurality of pressure or displacement sensors are installed on the upper end face of the steering ring. The steering ring comprises a left half ring and a right half ring which can be combined and detached. The running belt is used for simulating advancing and retreating, the steering ring is used for collecting the rotating direction of a user and controlling the rotating direction of the running belt, the steering ring surrounds the running belt in the center, the user body feeling of normal steering and the body feeling of advancing and retreating are truly simulated, signal collection is accurate, and virtual world control is accurate.

Description

technical field [0001] The invention relates to the technical field of VR equipment, in particular to a simulation steering treadmill for VR equipment. Background technique [0002] Virtual reality technology VR includes computer, electronic information, and simulation technology. Immersive experience is divided into non-interactive experience and virtual environment interactive experience. Compared with non-interactive experience in virtual environment, users can use equipment and virtual environment such as data gloves, digital scalpels, universal treadmills, etc. By interacting, the user at this time can perceive changes in the virtual environment, and can also control the virtual environment to make corresponding actions through real actions, thereby producing various feelings that may be generated in the corresponding real world. [0003] Among them, the universal treadmill, as the most important somatosensory and control device, can enable users to complete actions su...

Problems solved by technology

[0004] The first type of running belt, disclosed in CN112402942A is an invention patent named "a kind of VR game machine that uses a shoulder-back bar device to transport an omnidirectional treadmill" , the invention patent uses the running belt to simulate and collect the user's forward and backward electrical signals, and uses the shoulder bar to collect the user's turning signal; its advantage is that the running belt gives the user a better somatosensory feedback while collecting the user's forward and backward signals , when the user cooperates with VR glasses, the somatosensory feedback is closer to the real running somatosensory; the disadvantages are: 1. When the human body turns around, it is divided into body steering and steering steps, and the body's steering signal is collected by the shoulder bar

In actual use, it is not the rotation range of the human body that determines the specific angle of steering, but the angle of the first step when turning. The signal acquisition of the shoulder rod is not accurate and cannot meet the requirements of precise steering. AI algorithms can be used A certain degree of correction, but it can’t solve this problem; 2. The power of the rotation of the shoulder bar is transmitted through the power of turning the human body. It needs to fix the user’s upper body, and it will give the user a sense of resistance when turning around. It also hinders the user while completing other actions

[0005] The second type of universal wheel and spherical running device, in CN113476792A discloses an invention patent named "a VR universal treadmill mapping virtual position equipment" , the invention patent uses a ball assembly to realize the user's forward, backward and steering functions; its advantage is that the signal acquisition is accurate, the amplitude of forward and backward can be collected through the rotation stroke of the ball, and the steering angle can also be collected through the rotation direction of the ball ; Its shortcoming is that the user's physical sense is poor, and the feeling of moving on the ball and flat ground is greatly related, and it is easy to fall
