HTC showed off a new eye-tracking tech in its Vive VR headset line. Vive is aimed at the VR world, rather than the AR world being targeted by Apple, but AR and VR are kissing cousins, and this is interesting. The idea is simply that the headset can track your eye movements, which can then be used to activate menu and navigation controls. I think Apple is right to focus on AR, but there is obviously a big future in AR, too, and if HTC can bring this to market, it will make them a real player in that space. TheNextWeb has a good writeup from CES on this:
The biggest splashes came in the form of the new Cosmos hardware (an Oculus Go/Quest competitor) and a new eye-tracking system to be debuted in an update to the Vive Pro called “Vive Pro Eye.” Eye-tracking is a big deal for VR. The Vive Pro Eye, according to HTC, will accurately monitor users’ eye movements inside the headset.
