Interaction for entertainment contents based on direct manipulation with bare hands

We have developed an augmented desk interface system called the EnhancedDesk which allows us to interact with both physical objects and digital information projected onto a desk simultaneously; this interaction is accomplished by direct manipulation with our hands. During our technical demonstration of EnhancedDesk, a large number of visitors actually tried various applications developed for our system. In this paper, we describe those applications and the lessons that we learned during this demonstration.
