At least visually, the sensor seems somewhat similar to the designs of previous Intel RealSense developer kits that’s symmetrically designed with six sensors tracking the area in front of the headset.
He told us an accessory like this could track hand movement as well as IR-tracked controllers. The system could also scan the environment in real-time. This opens up the potential to detect obstacles automatically.
Leap Motion already has a developer kit out there which helps devs mount their sensor to the Vive and track user hand movement. It’s pretty great but there are some limitations with the scope of capture which works best when the hands are generally positioned right in front of the user.
