It's hard to say if this solution can work for me. Maybe I should just buy a ps3 camera and try out. they are cheap... Do you think that the ps3 camera can correctly track a body moving (using enough lighting)? correctly depends on the kind of data you want to get form the movement...

Hello all, I'm new to this list... I've just started out with PD, with body-tracking in mind actually. I'm working with the kinect - you can get it working on your OS of choice, via the wonderful community effort at: http://openkinect.org/wiki/Main_Page Seems like a natural fit for PD, and

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

We have been playing around with tracking and PD for several years. Camera solutions are relatively slow and inaccurate if you're thinking about human body motion like martial arts stuff etc. Apart from camera issues, it's also very dependent on lighting the scene and how you can mark or

hello, for the kung fu : movement are usually very fast. a camera is usually to slow to be useful. i personally prefer using sensor like accelerometter on the body. you can use wiimote or some other (faster) sensors system. here is a video of a performance i worked for few years ago.

If you want 3d and really fast... mocap. But they cost a lot and you have to wear the tiny capture reflective IR balls. Kinect is good, but latency exists. Games and developers do all sorts of filtering to simplify data and make it realtime usable. On Sat, Jan 8, 2011 at 7:16 PM, marcello

Not defending anything, but just to remind 60 fps of a pointgrey camera is not slow. you probably will have a lot of trouble in dealing with 60 frames trying to cycle through your code every second. Accels and other hardware sensors are very useful too, and it very good results. But not the best
