This paper describes the design and early experience with Cruiser–a multi-user, gestural, collaborative digital photograph sharing interface for a tabletop–and the techniques we use to share information with devices and other displays in its pervasive computing environment. The design is strongly influenced by the metaphor of physical photographs placed on the table and we have concentrated on the provision of an effective UbiComp interface that does not use a keyboard, a mouse or traditional WIMP (Windows, Icon, Mouse, Pointer) interface widgets. That is, with an emphasis on seamlessness. Aspects of the interface include the ability to interactively attach audio, handwriting or drawings, as well as other photographs to the “back” of an image after flipping it over; direct sharing of images with digital cameras, large displays and other UbiComp devices; and the provision of personal spaces–an area close to a user in which only they can work, which is enforced by the interface.
