Multitouch-Multiuser Table Computing is the new paradigm for accessing rich information in public spaces. As revolutionary natural user interfaces provide new ways of interacting with virtual information spaces, visual information developers must rethink their methodologies in the design of new applications that augments multiple user interaction and collaboration. This paper addresses a specific aspect of the multitouch-multiuser paradigm for virtual artefacts. Particularly, the paper addresses pilot developments of 3D multitouch-multiuser table applications in the presentation of heritage information in order to begin to qualitatively understand group behavior and user interactions on 3D information spaces using touch. The qualitative observations here pave the way for more structured quantitative usability studies.
