A testing device and method for a virtual reality system

Abstract

The invention relates to a virtual reality system testing device and method. The testing device comprises a testing controller and a testing module. The testing controller is used for generating control signals and sending the control signals to the testing module. The testing module comprises: a testing platform; a signal acquisition unit, which acquires signals displayed by a head-mounted device display of a virtual reality system to be tested, or acquires and displays signals of an external display of play images of the virtual reality system to be tested; and a motion drive unit, which receives control signals and drives the testing platform to move according to the control signals, so that the position of a head-mounted device of the virtual reality system to be tested changes. The testing module is controlled by the testing controller, so automatic testing of the virtual reality system can be realized, and parameters of display effects of the virtual reality system can be tested. The testing efficiency is high, and the accuracy is great.

Description

technical field [0001] The invention relates to the field of testing, in particular to a testing device and method for a virtual reality system. Background technique [0002] Virtual Reality (VR for short) is a technology that comprehensively utilizes computer graphics system and various display and control interface devices to provide immersive feeling in an interactive three-dimensional environment generated on a computer. Among them, the interactive three-dimensional environment generated by the computer becomes a virtual environment (ie, Virtual Environment, VE for short). Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. Immerse yourself in that environment. [0003] Virtual reality equipment was originally used in military aircraft, and currently involves a wide range of applications. Virtual reality displays with intelligent operating systems have begun t...

Problems solved by technology

The distortion of the projected image will not only affect the comfort of observation, but even cause the observer to misjudge important information, resulting in unnecessary loss

[0004] The biggest problem with virtual reality systems at the moment is that people cannot use them for long periods of time due to severe dizziness

Studies have shown that delay and position tracking error have a great impact on vertigo. If the delay is too large, it will cause the wearer to feel dizzy. The greater the delay, the stronger the wearer's vertigo. Therefore, it is necessary to compare the delay of virtual reality devices Accurate testing, so that designers can find and solve problems

Currently, virtual reality devices mainly use software methods to test the performance of the host, and users cannot determine the display delay and position tracking error of the entire virtual reality system
