How expensive is the virtual drum set?
Our system is only made up of :
2 webcams, 60$ each
2 plastic sticks with LEDs at one end, 10$ each
1 pedal (video game pedal), 10$
and a personal computer (we assume that the person already has a computer) with a screen (to visualize the 3d drums and the moves of your 3d sticks!)
Total is around 150$ , or 8 times less than a real drumset (by european standards).
