Leap motion controller only tracks finger/hand gestures (If I'm right). I need to track the motion of reference objects, such as dollies stuck to deforming objects, which is out of the tracking scope of sensors in the class of leap motion controller. Optotrack technology can definitely do this stuff perfectly, but at a huge financial investment. But what I need is a very affordable trick in the cost range of leap motion sensor (or a way to make leap motion sensor track a 'non-finger' object) at a similar resolution.

Thanks a lot.
