The Haptic Tabletop Puck: Tactile feedback for interactive tabletops
In everyday life, our interactions with objects on real tables include how our fingertips feel those objects. In comparison, current digital interactive tables present a uniform touch surface that feels the same, regardless of what it presents visually. In this paper, we explore how tactile interaction can be used with digital tabletop surfaces. We present a simple and inexpensive device - the Haptic Tabletop Puck - that incorporates dynamic, interactive haptics into tabletop interaction. We created several applications that explore tactile feedback in the area of haptic information visualization, haptic graphical interfaces, and computer supported collaboration. In particular, we focus on how a person may interact with the friction, height, texture and malleability of digital objects.
