Virtual Reality Eye Tracker First To Resolve Foveated Rendering Issues

China based 7invensun has launched what it is calling the world's first virtual reality (VR) eye-tracking module that can solve the technical problem of foveated rendering. The technology boasts three advantages: full field-of-view (FOV) tracking, high precision, and low latency.

Tracking range can reach the extremes of eye rotation, approximately 30° vertically and 50° horizontally. This covers mainstream VR devices with a FOV larger than 110°. Tracking precision is up to 0.5°, maximum tracking speed is 380 Hz, and latency is lower than 5ms.

The eye-tracking module also sports a novel hardware design with detachable modules, making them easy to carry and replace. This design also allows for replacement of near-sighted lenses. Every module is equipped with near-sighted lenses: one pair for 200°, 400°, and 600° each.

In terms of market acceptance, the company believes the main deterrent confronting VR hardware makers is that players' computer hardware is not able to meet the needs of display devices for high-resolution rendering. Additionally, VR equipment currently available can only function properly on computers that are priced at about $1,500 to $3,000).

In order to solve this problem, 7invensun is collaborating with companies such as NVIDIA and Qualcomm to develop foveated-rendering technology based on eye tracking. When we see a pure rendering scene, most of the computer work is wasted since our eyes can only accept details at the fixation point. Understanding the accurate field-of-view of users through eye-tracking technology, we only need to render the area with full resolution, to reduce the requirements for GPU.
