I’m thinking that this hand gesture recognition software might be a good way to get some more input for the low-cost VR system, or it just might be a lot of fun…“With almost any color camera and sufficient processing power, this software collection implements a hand gesture interface. It detects the hand in a standard posture, then tracks it and recognizes key postures – all in real-time and without the need for camera or user calibration.” Thanks Jerry! Link.
