Body movement recognition device used for virtual reality input

Abstract

The invention discloses a body movement recognition device used in virtual reality, which belongs to the technical field of a man-machine interaction technology in a virtual reality technology. In order to solve the technical problem, the invention provides a more humanized and simpler input device compared with an input technology based on a mouse and a keyboard in the conventional man-machine interaction, so as to realize the seamless connection of a virtual world and a real world. The key point of the technical scheme to solve the problem is that: the recognition of the body movement is converted into the recognition of a track of special equipment through handheld special equipment; the body movement is transcribed into a three dimensional (3D) location data stream by a 3D location system of which the precision reaches a millimeter scale and which meets the real-time requirement; and a 3D location data sequence comprising the body movement information is intercepted from the data stream so as to recognize the corresponding body movement to further transmit a control command corresponding to a specific application scenario; therefore, the purpose of controlling the virtual world is achieved. The invention is mainly used for replacing the mouse and the keyboard in certain application scenarios of the virtual reality technology, so as to provide a more humanized and simpler controlling manner for a user.

Description

technical field [0001] The invention relates to a technology for recognizing body movements by holding a special device, in particular to a body movement recording system with a positioning accuracy of millimeter level and meeting real-time requirements, and a body movement interpretation middleware. Background technique [0002] Virtual reality technology is widely used in entertainment, scientific research, education, military, aerospace and many other fields, mainly involving computer graphics, artificial intelligence, sensor technology, human-computer interaction technology and other technical fields. Among them, the human-computer interaction technology is the bridge between the virtual world and the real world, and how to realize the seamless connection between the two is very important. In traditional human-computer interaction, the input mainly depends on the mouse and keyboard, and the output mainly depends on the monitor and audio. The input methods provided by th...

Problems solved by technology

The input method provided by the mouse and keyboard needs to master the mouse and keyboard input operation. On the one hand, it is a learning threshold for many people. On the other hand, it is not humane enough.

[0003] It can be seen that the input technology in traditional human-computer interaction needs to be improved, and this is also a research hotspot in virtual reality technology.
