i'm trying to implement like this in my application http://www.youtube.com/watch?v=QrXwJIco4w8
but it seems i don't really get the idea how to do it..
seems i must use motion tracking and hand recognition, also communicate with front-end camera, but mostly link that i found only show detect OUTSIDE object not INSIDE object(means inside device).
so what i want is if there is object(like image or anything) in application, then when i move my hand in front of camera like go to left, then the image position also go to left. Make the image move without interact with touch but using camera instead(touchless)
Can you help me show way to do it?
thanks
