Presenting using two-handed interaction in open space

Based on recent demonstrations of low-cost, infrared-based point tracking, we explore two-handed, surface-less interaction for presentation. On both hands, thumb and index finger are equipped with retro-reflective markers which are tracked by a Wiimote. We contribute a robust finger pairing and pinch recognition method that allows us to discriminate the hands and to initiate actions. We apply this input to a presentation application that allows users to work with slide decks, images, and videos. We identify specific requirements of this application domain and discuss the implemented transformation interactions and widgets. We report on user experience in both casual use and an actual presentation as well as discuss advantages and limitations.
