During the past months I’ve been working on a multi-touch and multi-user framework for table-top applications that can use tangible objects. This last characteristic is supported by considering the binding between a gesture and a phisical object that represent the target (destination) control. It relies upon a Tuio server, such as reactivision.
It’s still in the alpha state, but usable and expecially testable Comments are very welcome, expecially the negative ones.
It has no instructions yet, but if you ask me some questions it will be easier for me to write a guide.
