This paper examines the current state of museum guide technologies and applications in order to develop an analytical foundation for future research on an adaptive museum guide for families. The analysis focuses on three critical areas of interest in considering group and social interaction in museums: tangibility the role of tangible user interfaces; interaction visit types and visit flows; and adaptivity user modeling approaches. It concludes with a discussion of four interrelated trajectories for interactive museum guide research including embodied interaction, gameplay, transparent and opaque interaction and the role of personal digital assistants
