7Invensun to release eye tracking hardware for HTC Vive VR headset

Virtual reality is slowly becoming a viable product in the market. Although at the moment, hardware related to the technology are still a bit expensive, some users still find VR to be a very appealing piece of tech. Ever since the release of the Oculus Rift and HTC Vive, there have been a number of similar hardware for VR gaming. However, just like the two mentioned devices, these similar VR headset also do not have an eye tracking feature.

Eye tracking is achieved by viewing the user’s retina with infrared cameras and then applying computer imaging to follow the motion of the user’s eyes. This is the case for the FOVE VR headset. Unfortunately, there are still many months before the headset gets released in the market. Fortunately, there is a neat eye tracking solution that can be used to VR headsets especially the HTC Vive.

Chinese company 7Invensun has come up with a hardware that fits with the HTC Vive to give it the much-needed eye tracking feature; the aGlass.

The aGlass can be fitted directly into an HTC Vive VR headset with minimal disassembly. It comes with the proprietary tools and a set of simple instructions to get anyone started with eye tracking VR experience.

The eye tracking hardware features full FOV tracking with precision level of less than 0.5 degrees. It also has a relatively low latency of 5ms thanks to its high refresh rate. In addition to the eye tracking hardware, the manufacturer is also throwing in three pairs of myopic lenses free of charge. The device also comes with the necessary drivers to make it possible for the HTC Vive to render foveated images on the headset displays.

The device is now on pre-order for $220 and will be released in China as early as next month. For other regions, the aGlass will start to roll out towards the third quarter of 2017. For more tech updates, be sure to check us out at TheBitbag.
