Oculus Research Have unveiled new display technology this week in the form of the Focal Surface Display, for which they have published a paper that will be presented at the SIGGRAPH conference this July.
A video has also been created to explain the new Focal Surface Display technology and provide an insight into how it may be able to eliminate the need for prescription glasses when using virtual reality headsets.
Oculus Research explains more about the “groundbreaking” Focal Surface Display:
Focal surface displays mimic the way our eyes naturally focus at objects of varying depths. Rather than trying to add more and more focus areas to get the same degree of depth, this new approach changes the way light enters the display using spatial light modulators (SLMs) to bend the headset’s focus around 3D objects—increasing depth and maximizing the amount of space represented simultaneously. All of this adds up to improved image sharpness and a more natural viewing experience in VR.
By combining leading hardware engineering, scientific and medical imaging, computer vision research, and state-of-the-art algorithms to focus on next-generation VR, this project takes a highly interdisciplinary approach—one that, to the best of our knowledge, has never been tried before. It may even let people who wear corrective lenses comfortably use VR without their glasses.
Focal surface displays continue down the path set by varifocal and multifocal concepts, further customizing virtual images to scene content. We have demonstrated that emerging phase-modulation SLMs are well-prepared to realize this concept, having benefited from decades of research into closely-related adaptive imaging applications. We have demonstrated high-resolution focal stack reproductions with a proof-of-concept prototype, as well as presented a complete optimization framework addressing the joint focal surface and color image decomposition problems. By unifying concepts in goal-based caustics, retinal scanning displays, and other accommodation-supporting HMDs, we hope to inspire other researchers to leverage emerging display technologies that may address vergence-accommodation conflict in HMDs.
