TUIO: A Protocol for Tangible User Interfaces

Tuio is a simple yet versatile protocol designed specifically to meet the requirements of table-top tangible user interfaces. Inspired by the idea of interconnecting various existing table interfaces such as the >reacTable, being developed in Barcelona and the tDesk from >Bielefeld University, this protocol defines common properties of controller objects on the table surface as well as of finger and hand gestures performed by the user. Currently this protocol has been implemented within a fiducial marker-based computer vision engine developed for the reacTable project. The Tuio protocol has been implemented using >OpenSound Control and is therefore usable on any platform supporting this protocol. At the moment we have working implementations for Java, C++, PureData, Max/MSP, SuperCollider and Flash. For updated information and corrections, please confer to the >official page of TUIO
