DIY EYE AND FACE TRACKING FOR THE VALVE INDEX VR HEADSET
The Valve Index VR headset has been around for a few years now. It doesn’t come with eye or face tracking, but that didn’t stop inspired folks like [Physics-Dude] from adding DIY solutions in elegant and effective ways using a combination of hardware, open software, and 3D printable parts.
This project leverages the EyeTrackVR project (and optionally, Project Babble for mouth tracking) which both have great applications particularly in social VR spaces.
These are open-source, self-contained and modular solutions intended for a variety of hardware platforms. Of course, every millimeter and gram tends to count when it’s something that gets worn on one’s head, so [Physics-Dude] tailored a solution specifically for the Valve Index. His project makes great use of the platform’s hacker-friendly hardware design.
[Physics-Dude] also makes excellent use of a certain widely-available “gumstick” style USB hub as an important part of his build. Combined with with the front-mounted USB port on the Index, it results in an extremely compact and tightly integrated solution that looks great. While it can be risky to rely on a particular off-the-shelf item in a build, doing so absolutely has its place here.
