I'm working on a kinect virtual drum kit. I was wondering if any of you guys had any idea on how i could achieve velocity when using the kinect??

You have to compute the distance between two position.

(if you want an external look at my tools or the zsa objects, there are objects that compute distances)

The most difficult is to know wich values to take. I think the best is to take the values when y is highest for time 0 and lowest for time 1.

Hi,
You have to compute the distance between two position.
distance  = sqrt((x0 - y0)2 + (x1 - y1)2)
(if you want an external look at my tools or the zsa objects, there are objects that compute distances)
then compute the velocity :
velocity = distance/time
