NHK develops thin light field HMD to reduce eye strain using ray tracing technology

NHK Science and Technical Research Laboratories has developed a new thin light field head-mounted display. The prototype aims to reduce visual fatigue for users by matching perceived depth with eye focus.

Prototype matches perceived depth with eye focus for VR applications

The device uses ray tracing technology to generate elemental images at high speeds. This approach allows the optical path depth to shrink significantly compared to conventional designs. NHK reports that the optical path depth reduced by 79 percent relative to standard light field HMDs.

The development targets applications in virtual and augmented reality environments. The laboratory focuses on creating more comfortable viewing experiences for extended use sessions.

NHK has not confirmed a commercial launch window or pricing details for this prototype.
