Researchers at Nvidia and the American University of Stanford have developed a prototype of a pair of VR glasses that is significantly thinner than the VR glasses / headsets used today.
One of the reasons why today’s VR headsets and VR glasses are so large is because the screen and magnifying glasses need to be at a certain distance from each other. Nvidia and Stanford have solved this by using so-called pancake lenses, lenses that can usually only show 2D images. Nvidia writes about how they developed the thin VR glasses:
“While prior VR displays require distance between a magnifying eyepiece and a display panel to create a hologram, this new design uses a spatial light modulator, a tool that can create holograms right in front of the user’s eyes, without needing this gap. Additional components – a pupil-replicating waveguide and geometric phase lens – further reducing the device’s bulkiness. “
The actual screens and associated technology in the prototype that Nvidia has developed are only 2.5 mm thick. The prototype will be shown in more detail at this summer’s SIGGRAPH trade fair, which kicks off on August 11 in Vancouver, Canada. When we could possibly see VR glasses like these on the market, there is so far no information about.
