Researchers create AR headset that shows objects without nausea

Researchers from the University of Cambridge have developed a head-mounted display for augmented reality applications that realistically displays 3D objects without the user experiencing any nausea or eye strain.

The researchers from the Center for Advanced Photonics and Electronics, together with the Munich-based Huawei European Research Center, have developed a head-mounted display for ar applications in which images or objects are projected onto the user’s retina by means of pixel beam scanning. This means that these objects, for example a 3D representation of a rotating DNA strand, remain completely sharp, regardless of the distance at which the user has his eyes focused.

As part of the research, a study involving more than fifty participants between the ages of 16 and 60 was conducted. According to the researchers, they indicated that the 3D effect was ‘very convincing’ for objects from 20cm to 10m. In addition, they indicated that the images and videos shown had vivid colors and high contrast and that no pixels were visible. None of the participants experienced nausea or eyestrain after prolonged use of the headset.

The lead researcher of this project, Professor Daping Chu of the University of Cambridge, says his team’s research has yielded an AR experience that can rival that of ‘comfortable 3D viewing’ and the lack of unwanted side effects such as nausea. products from the market leaders. The screen also works for users with glasses. It is still a prototype, so it is still unclear whether this product or the technology behind it will become more widely available soon.

The research is published in the scientific journal Research, under the title Accommodation-Free Head Mounted Display with Comfortable 3D Perception and an Enlarged Eye box.
