According to different people's visual differences, adaptive display of VR heads
Myopia has become more and more common nowadays, or inherited, or acquired factors. VR imaging is particularly delicate in the calculation of the line of sight. The depth of field and other effects of the normal line-of-sight design can cause various optical problems due to the line of sight and may even cause the user to feel dizzy or nausea.
Although some headphones nowadays have an adjustment function that can adjust the distance between the front and the back of the lens and the distance between both eyes, this is not necessarily suitable for all users, and when different vision users use it, it is necessary to adjust the head display again and again.
"Everyone needs a different optical model to get the best VR experience," Gordon Wetzstein of Stanford University said in a press release. His team's research published today in the proceedings of the National Academy of Sciences describes a set of mechanisms that make up what they call adaptive focus displays.
This is a method of using a liquid lens. The shape of the lens can be used in head-up operation to adjust for certain situations. For example, when the focus of the game is not normally focused on the viewer target object, the screen itself can also be changed to better fit the user's optical needs. Simple vision correction is just the first step but more complex situations like astigmatism require more complicated solutions.
"The technology we propose is fully compatible with existing head-mounted displays," Wetzstein said. "However, it needs to be combined with eye-tracking technology to work properly. Eye-tracking is one of the mainstream research technologies in the industry. We expect that eye-tracking technology will become the standard for the next generation of head-ups. Therefore, our gaze will show These heads are directly compatible.
