I started trying to find useful things to do with face detection, but with limited success. I tried using the Libspark Haar Cascades implementation of face detection with Papervision3D to create a sort of head tracking effect, but it’s a little flaky – partly because of poor tracking accuracy and partly because it’s too CPU intensive. You can view it on its own page here.
I made this globe that ‘should’ look up your IP address and point to where you are on Earth – the nearest city at least. Am I close? 😉
Playing around some more with my webcam, I cooked up this 3D Earth with Papervision and made it controllable through a webcam (if you have one). The motion detection is rather flaky, since it tracks the centre-point of a whole area of motion – if you move a lot it will just get confused 🙂
