I’m really curious about detecting hand gestures (middle-finger, peace sign) for multiple users.
I’m envisioning a round coffee table that lets you play rock-paper-scissors, and then riff off that interaction.
I came across this post on triangulation http://forum.openframeworks.cc/t/triangle-c+±wrapper–2d-mesh-amp;-delauny/547/0 that seemed to mention hand gestures, although I’m unclear how it relates?
My attack on the problem thus far has been to grab the furthest points on a contour from the center of a blob. Right now I’m working on calculating the normal of each point, and then find the peaks and valleys by the change in normals across the contour.
Is there any existing open source software to take care of some of this heavy lifting? Any recommended reading?
Now that I think of it, its a lot like shadow monsters… http://www.youtube.com/watch?v=a-GxN07uKvQ
Thanks very kindly in advance,
