Físchlár-DiamondTouch is a multi-user, co-located, collaborative video search system. It allows two users to sit opposite each other at a tabletop system and search for video shots. The system was evaluated at the TRECVid2005 workshop.
More details on the system can be found in the paper: Collaborative Video Searching on a Tabletop. Smeaton A.F, Lee H, Foley C and Mc Givney S. Multimedia Systems Journal, Vol. 12, No. 4, 2006. (pp375-391)
