Simple single finger tracking for Vive

Just had a look at the latest from Leap Motion, cool stuff, would really add a lot to the experience with flight sims where you don't need the controllers but need to interact with the virtual cockpits when you take your hands off the throttle or stick.



But a simpler way to do that: Vive already has the front facing camera. It would be fairly easy for it to track a small ball, PS Move style but smaller, attached to a ring worn on the index finger. Voila.



You have the location of the Headset, the algorithm just needs to work exactly as the PS Move tracking, that determines the direction and distance of the ball knowing its diameter. You can then have your finger fairly accurately tracked, and that's all you really need to press buttons or flip switches in a virtual cockpit...with a million more possible applications. So just a ring with a bright color, 1-2cm diameter ball on it, and the rest is just software. And there are of course more sophisticated similar solutions.



Posted this on oculus reddit earlier but no hope. Would SteamVR devs be interested in implementing something like this? If not I might sit down and do it on my own for Unity, I expect the camera's specs will be adequate and we can also access it and use the feed as we like?



Edit: is this the right place for this?
