NHK Science & Technology Research Laboratories develops a thin, light-field VR headset that reduces visual fatigue.

NHK Science & Research Technology Laboratories (STRL) introduced on May 21, 2026, that it has developed a skinny, light-field VR headset that reduces visual fatigue. It will likely be exhibited at “STRL Open House 2026,” which will likely be held from May 28.

Conventional VR headsets create a sense of depth by exhibiting barely offset pictures to the left and proper eyes. However, even when objects within the picture transfer backwards and forwards, the eyes’ focus stays fastened on the show’s place. This “discrepancy between focus and depth perception” is considered the reason for fatigue and discomfort. To handle this challenge, NHK Science & Technology Research Laboratories has been growing a light-field sort HMD.

A light-weight area is a know-how that reproduces the gathering of sunshine rays emitted from an object that attain the attention. Because it lets you concentrate on the specified location identical to in the actual world, it’s anticipated to offer a much less tiring picture show even throughout extended use.

In this prototype, we developed a new optical system that makes use of two sorts of lenses with completely different capabilities in touch with one another. Conventionally, an intermediate picture was shaped earlier than magnification, requiring a hole of roughly 4 cm between the lenses. With the brand new optical system, we succeeded in delivering a 3D picture on to the attention with out going by means of an intermediate picture, and diminished the depth of the optical system by 79% in comparison with typical techniques. By combining a high-definition microdisplay with ray tracing know-how that processes mild rays at excessive pace, we now have additionally confirmed the real-time show of high-definition 3D pictures.

NHK Science & Technology Research Laboratories Open House 2026 will likely be held from Thursday, May twenty eighth to Sunday, May thirty first on the NHK Science & Technology Research Laboratories (Kinuta, Setagaya-ku, Tokyo). Opening hours are from 10:00 AM to five:00 PM. Admission is free and no prior reservation is required.
