Problems solved by technology
One of these methods is electrical stimulation, however long-term use of this method can be potentially harmful to the body
In order to find an alternative method of electrical stimulation, the researchers chose to use bone conduction vibration to solve VR disease. This method can avoid the potential threat of electrical stimulation, but it is difficult to promote because the equipment is too complicated
Other researchers have studied a simpler and more effective method, installing two mechanical devices near both sides of the vestibular system of the head, and the user taps the head alternately while walking in the virtual scene to achieve the synchronization of the user's footsteps Effect, this method has been proven to be effective, but these methods have a certain sense of discomfort, which may affect the sense of immersion

Embodiment approach
[0039] The software optimization part implementation method of the present invention is as follows:
[0040] In daily life, people usually squint or close their eyes when they are dizzy and uncomfortable, and the visual angle when people squint slightly is also larger than the field of view of the current mainstream high-performance VR headsets on the market, so we have reason to think that the field of view The effect of blurring the edges is similar to the state of human beings who squint slightly. So we refer to and improve the method mentioned above to combat VR disease through subtle dynamic field of view modification, and finally choose the initial blurring of the field of view, and then simulate the state of squinting to gradually reduce the field of view. It is supplemented by optimizing the rendering pipeline to reduce the performance improvement caused by Gaussian blur.
[0041] Our dynamic field of view adjustment scheme is: when the user turns and the speed is det...

Description
technical field [0001] The invention belongs to the field of multimedia vision, and in particular relates to a method and system for alleviating virtual reality disease through adaptive training, including algorithm and software design. Background technique [0002] In recent years, virtual reality (referred to as VR) has been developed quite rapidly. Due to its relatively low cost and the ability to simulate real scenes in more complex environments, it has been widely used in medical, entertainment, military, industrial manufacturing and many other fields. industry. From the advent of VR to its widespread use, it has been accompanied by a more serious problem-VR disease, sometimes called motion sickness, which can cause symptoms similar to motion sickness, including headaches and stomach discomfort , pale, sweating, disorientated, etc. According to research, if users have an unpleasant initial experience with VR, they will not want to try again. Therefore, solving VR sick...
