Hi, As Cyrille says a good choice is the wii and its accelerometer, you can even hack and reduce weight and dimensions, the three-axis accelerometer or sensor flex not recommend to you, take away the freedom to be wired.
I heard that the camera play 3 works very well for tracking, even I could prove it. Maybe if you dont want hardware, it would be Gesture Processing library in connection with Pd via OSC. That library can keep track and memorize your gesture … There is something similar in pd?
