Problems solved by technology

The present invention solves the following core technical problems: (1) Utilize ultrasonic waves for distance measurement, which overcomes the limitation that the measurement results caused by infrared ray measurement are affected by light and the distance is short; (2) Utilize multiple sensors to measure the distance in four directions , overcoming the disadvantages of only a single azimuth distance measurement in the past that could not prevent collisions in other azimuths

Abstract

The invention discloses a VR interactive reality collision prevention method based on ultrasonic ranging. Based on ultrasonic distance measurement, man-machine interaction with a person is carried outfor preventing collision according to the distance. Ultrasound is used for distance measurement, and the limitations that a measurement result is influenced by light and the distance is short by infrared distance measurement can be overcome; multiple sensors are used to measure the distances in four directions, the disadvantage that collision can not be prevented in other directions as the distance in only one direction is measured previously is overcome, and a user can perform VR activities more freely; the user can be prevented against collision through a different user prompting scheme mode for a different distance, and while the safety is ensured, reduction of the immersion illusion of the user in the VR activity process can be avoided.

Description

technical field [0001] The invention relates to the fields of virtual reality and human-computer interaction, in particular to an anti-collision method for VR interactive reality based on ultrasonic distance measurement. Background technique [0002] Virtual reality (Virtual Reality, hereinafter referred to as VR) technology was first proposed in the 1980s, using computer-generated virtual multi-source information for fusion of interactive 3D dynamic scene and system simulation of entity behavior, allowing users to experience virtual reality in a virtual environment. Interact immersively with objects. [0003] VR headsets use head-mounted display devices to close people's vision and hearing to the outside world, and guide users to feel like they are in a virtual environment. The display principle is that the left and right eye screens display the images of the left and right eyes respectively, and the human eyes will generate a three-dimensional feeling in the brain after o...
