Trackmate
February 9 2009
Object tracking made easy. Trackmate is an open source initiative to create an inexpensive, do-it-yourself tangible tracking system. The Trackmate Tracker allows any computer to recognize tagged objects and their corresponding position, rotation, and color information when placed on a surface. Trackmate sends all object data via LusidOSC (a protocol layer for unique spatial input devices), allowing any LusidOSC-based application to work with the system.
To start experimenting download the tracker, LucidOSC for Processing, print some tags and build a reader.(there are more ways than just this one, look at the homepage)
