Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as figure 1 As shown, the arm simulation device includes two hinged connecting rods 1-1, a strap 1-3 is arranged on the connecting rod, and an infrared emitting device 1-2 is arranged on each connecting rod; the infrared rays emitted by the infrared emitting device The light is irradiated on the infrared receiving matrix 1-4, so that the infrared receiving matrix will output the position signal of the connecting rod, and then transmit the signal to the image processing device 1-5.

[0018] On the image processing device 1-5, a virtual arm proportional to the size of the connecting rod is designed in advance through the drawing software, and the position of the infrared device on the connecting rod is also marked on the virtual arm. Then the bending state of the connecting rod can be obtained, thereby correspondingly changing the co...

Abstract

The invention discloses a virtual reality system comprising an arm simulation device and a force feedback data glove device, wherein the arm simulation device comprises two sections of connection rods which are hinged with each other; the connection rods are provided with binding bands and each section of the connection rod is respectively provided with an infrared ray emission device; the device further comprises a vertical plane plate and an infrared ray receiving matrix is arranged at one side of the plane plate; an output signal of the infrared ray receiving matrix is connected with an image processing device and a virtual arm image proportionable to the connection rods is output by the image processing device; a bending change of the virtual arm is controlled through the output signal; the force feedback data glove device comprises a glove and an air bag is arranged on the inner wall of the glove; and the air bag is connected with an air pump through a guide pipe and a controller which is connected with the air pump is used for controlling inflation and deflation of the air pump. According to the invention, movement conditions of the arm can be displayed in real time and hands of a user are compressed by controlling the inflation and deflation of the air bag in the glove; and the virtual reality system provided by the invention is easy to realize and lower in cost.

Description

technical field [0001] The invention relates to a virtual reality simulation device. Background technique [0002] Virtual reality is one of the most cutting-edge technologies at present. Through virtual reality equipment, it simulates real-life scenes and gives users a new experience. [0003] At present, many colleges and universities have opened virtual reality courses to explain the principles and realization of simulated reality to students. However, because virtual reality teaching aids are relatively expensive, a data glove or a dynamic simulation tool usually costs tens of thousands of yuan, which brings a great burden to the school. Students cannot use the tools for experiments and can only read the written descriptions. It affects the teaching. Contents of the invention [0004] The purpose of the present invention is to provide a simple virtual reality system. [0005] In order to achieve the above object, the following technical solution is adopted, a ...
