Description

Background Art

[0002] Virtual reality has three main characteristics: immersion, interactivity, and imagination. Immersion means that the external environment simulated by the computer simulation system is very realistic. Users are completely immersed in the three-dimensional virtual environment. It is difficult to distinguish between the real and fake simulated environment. Everything in the virtual environment looks real and feels exactly the same as the real world, which makes people immersed in it. Interactivity means that users can operate objects in the virtual world and get feedback. For example, users can grab an object with their hands in the virtual world. The eyes can perceive the shape of the object, the hands can perceive the weight of the object, and the object can move with the manipulation of the hands. Imagination means that the virtual world greatly broadens people's imagination in the real world. Not only can people imagine real scenes in the real world, but also imagine situations that do not exist or cannot happen in the objective world. According to the different levels of user immersion and participation methods, virtual reality can be divided into four categories: non-immersive virtual reality, immersive virtual reality, distributed virtual reality system and augmented virtual reality system.

[0003] However, in the prior art, for the actual application of VR devices, since the users are dynamic in most cases, the visual experience is different in different motion states of the users, and for some VR games, the picture is the main influencing factor for the user in the immersive experience.
