Ok, so i'm wondering if anybody has any experience when working with tangible tracking interfaces such as the ones used under the Trackmate initiative.

Essentially an OSC protocol called LusidOSC enables a webcam to track the position of tagged objects on an acrylic (plexi-glass) sheet by decoding the tags using a software called 'Trackmate Tracker' that then sends OSC information on port 3333 to any recipient; in this case the recipient is Processing.

In Processing I have created a sketch which is essentially two balls. I have it so that I can control one of the balls with an object on the surface and can use this to 'bounce' the second ball around the window.

Every time the second ball hits the boundaries of the window it sends an OSC message to Pure Data which is then used to trigger 8 random notes on a major scale with random duration. This patch is included.

Essentially i'm wondering if anybody has any suggestions on how i could improve on my patch in order to make it more interesting, and how i would go about implementing any of the suggestions that you might have.

Any help would be extremely appreciated as i'm fairly new to Pd.

Thanks for taking the time to read this!

I just discovered Trackmate and your post. I just finished building a rePatcher to use with PD and have some interest in building a more complex tangible interface. Perhaps if you posted a video, we could see how it works. Otherwise, readers of the forum would have to build the Trackmate to test your patch.
