VR (virtual reality) device based display method and system

Abstract

An embodiment of the invention relates to the field of display technologies, in particular to a VR (virtual reality) device based display method and system. The VR device based display method comprises steps as follows: when a VR device works in a normal state, a display unit is controlled to work in a display state in a first predetermined area; collected data of head motion is obtained, and compensation data is formed through calculation of the collected data; a first display area is formed through combination of the compensation data and the first predetermined area, so that the first display area is matched with the compensation data. According to the VR device based display method and system, a compensation area is reserved by the VR device, when a user transmits the head motion, a current first predetermined display area is switched to the first display area matched with the head motion by means of the compensation area, only the current display area is switched instead of switching of display of the whole screen, so that VR display delay is reduced, anti-shaking effect of VR display is improved, and dizzy feeling is avoided.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display method and system based on a VR device. Background technique [0002] VR (Virtual Reality Virtual Reality) technology is a computer simulation system that can create and experience a virtual world. It mainly uses a computer to generate a simulated environment. VR technology is an interactive three-dimensional dynamic scene and entity that combines multi-source information. A behavioral simulation system aims to immerse users into a three-dimensional dynamic scene through the simulation system to achieve an immersive effect. [0003] With the successive interviews of VR products such as Oculus and VIVE, the VR industry is gradually entering people's attention. However, there is an objectively obvious technical defect in existing VR products—too strong dizziness. Many VR experiencers or users experience dizziness, nausea, or even vomiting a...

Problems solved by technology

[0004] There are many reasons why VR products cause users to feel dizzy. One of the main reasons is delayed display, that is, when the user rotates the viewing angle or moves, the switching speed of the VR display screen is not synchronized with the user's movement, or the user's movement range is relatively slow. Small, the VR display screen is not updated in time and other asynchronous reasons lead to such a delay in the VR full-view screen, which causes the user's expected screen to be inconsistent with the VR display screen, which in turn easily makes the user's spatial positioning obstacle and produce a kind of Motion or positional illusions, and then produce adverse reactions such as dizziness and even vomiting. Specifically, if the user uses the position of his own eyes as the static reference position, the VR display screen will be in a state of shaking relative to the user's eyes. With the passage of time, the shaking state becomes severe. At this time, the user has a positioning obstacle to the screen information (or spatial information) displayed in VR, and cannot accurately locate the VR display screen. At this time, the user is likely to have a positional illusion.
