Description
Technical Field
[0001] The invention belongs to the technical field of virtual reality and human-computer interaction, and relates to virtual reality positioning technology, in particular to a virtual reality positioning belt and a positioning system thereof. Background Art
[0002] Virtual reality technology is a virtual three-dimensional space created by computers. By wearing virtual reality headsets, data gloves, tactile feedback devices and other equipment, users can simulate their senses such as vision, hearing and touch, making them feel as if they are in the real world. Because virtual reality has the characteristics of multi-sensory, interactive and autonomous, many scholars use it to conduct research in their respective fields.
[0003] The common virtual reality devices on the market, such as the HTC Vive virtual reality helmet set, mainly include virtual reality helmets, handles, laser locators, etc. Among them, the virtual reality helmet is mainly worn by users, the handle is used to control the user's movement in the virtual environment, and the laser locator is used to locate the user's spatial position and orientation in the virtual environment.
[0004] However, in the prior art, when a user uses a virtual reality helmet and a handle to move in a virtual environment at the same time, the laser locator can only locate the direction of the user's head. Therefore, when the user uses the handle to move in the virtual environment, he can only move in the direction of his head. This is inconsistent with the situation in reality that when a person moves forward, he will turn his head left and right to observe. For example, if you walk forward in a virtual environment, when the direction of your head changes, the direction of travel will also change. This situation will cause discomfort in operation and make some users feel more dizzy when using virtual reality equipment. Summary of the invention
[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide a virtual reality positioning belt and a positioning system thereof, which can be used in conjunction with a virtual reality helmet to locate the body orientation and movement direction of a user in a virtual environment.
[0006] The present invention solves the practical problem by adopting the following technical solutions:
[0007] A virtual reality positioning belt comprises: a belt body and at least two belt space locators; the belt locators are fixed on the belt body.
[0008] Moreover, two waist belt space positioners are fixedly mounted on the waist belt body, and the two waist belt space positioners are respectively and symmetrically mounted on both sides of the user's waist.
[0009] Moreover, the belt body includes belt loops made of hard material, an elastic belt is passed through the belt loops, and a belt buckle is installed at the front end of the belt loops; a belt space locator fixing device is fixedly installed on the left and right sides of the belt loops, and the belt locator is fixedly installed on the belt space locator fixing device.
[0010] A virtual reality positioning system comprises a graphics workstation, a virtual reality helmet, a virtual reality positioning belt, a virtual reality positioning belt wireless signal receiving device and a virtual reality laser locator; the graphics workstation is used to run a virtual scene; the output end of the graphics workstation is connected to the virtual reality helmet, and is used to output the image and audio information of the virtual scene running in the graphics workstation to the virtual reality helmet;
[0011] The virtual reality laser locator is connected to the virtual reality helmet, and is used to detect and define the spatial position of the virtual reality helmet in the real scene; the virtual reality laser locator is also connected to the graphics workstation, and is used to output the spatial position information to the graphics workstation, and the graphics workstation synchronously maps the spatial position information to the virtual environment; the virtual reality helmet determines the orientation and spatial position of the virtual reality helmet according to the spatial position of the virtual reality helmet in the real scene defined by the virtual reality laser locator, and outputs the orientation and spatial position of the virtual reality helmet to the graphics workstation, and the graphics workstation synchronously maps the spatial position of the virtual reality helmet in the virtual environment;
[0012] The virtual reality laser locator is also connected to the virtual reality positioning belt, and is used to detect and define the spatial position of the virtual reality positioning belt in the real scene; the virtual reality positioning belt includes at least two belt space locators fixed on both sides of the belt, and the belt space locators are used to determine the spatial position and orientation of the virtual reality positioning belt according to the spatial position of the virtual reality positioning belt in the real scene defined by the virtual reality laser locator; the output end of the belt space locator is connected to the graphics workstation through the belt wireless signal receiving device, and is used to output the spatial position and orientation information of the virtual reality positioning belt to the graphics workstation through the belt wireless signal receiving device, and the graphics workstation simulates the user's body into a capsule body according to the spatial position and orientation information input by the virtual reality positioning belt.
[0013] Moreover, the graphics workstation is also connected to a virtual reality control handle to transmit motion control signals of a virtual reality helmet and a virtual reality positioning belt to the graphics workstation, and the graphics workstation synchronizes the movement direction of the user in the virtual environment according to the motion control signals of the virtual reality control handle.
[0014] Advantages and beneficial effects of the present invention:
[0015] 1. The present invention uses a virtual reality positioning belt. When a user uses a virtual reality device to experience a virtual scene, the body movement is controlled to be closer to the movement principle of a person in a real scene. That is, through two belt space locators, the position coordinate information of the two ends of the belt is transmitted to the graphics workstation, and the graphics workstation determines the plane where the line segment is located based on the line between the two points. And combined with the ray emitted by the virtual reality helmet to the front, the front and back directions of the plane are determined, and the front direction is the front direction of the user's body. And mapping is performed in the virtual environment, so that the movement direction in the virtual environment can be the direction of the user's body, rather than the direction of the head, so that such a movement mode is closer to the movement mode of a person in a real environment.
[0016] 2. The present invention adds a body orientation positioning belt to the existing virtual reality device, so that the laser locator can simultaneously locate the body orientation and the head orientation. During the movement process, the movement direction is the body orientation, that is, the movement direction of the legs, rather than the head orientation, thereby reducing the dizziness caused by specific people when using virtual reality devices to a certain extent.
