Hi all,

I want to track my hand motion through a web cam. It should capture only my hand movement. According to that movement, I want to move some object (say colored rectangle) on the screen. [like shown in example 2].

The other thing is, the movement is motion should be as smooth as in example 2.

Here below you can see some good examples for what I want to develop. I tried this of my own using some image processing libraries, but it didn't work anyway. Can anybody please help me to do this? If I can have some sample demo project, then it is better.

I know some of you can guide me. If you need further details please tell me....
