We present an ambient display for supporting social connections between extended family members. The display, a digitally-controlled combination of oil on canvan and mechanical sculpture, consists of four, ten-by-ten inch "pixels", supporting the display of five coherent images and hundreds of mixed, collage images.

Because of its promise of natural interaction, recognition is coming into its own as a mainstream technology for use with computers. Both commercial and research applications are beginning to use it extensively. However the errors made by recognizers can be quite costly, and this is increasingly becoming a focus for researchers. We present a survey of existing error correction techniques in the user interface. These mediation techniques most commonly fall into one of two strategies, repetition and choice. Based on the needs uncovered by this survey, we have developed OOPS, a toolkit that supports resolution of input ambiguity through mediation. This paper describes four new interaction techniques built using OOPS, and the toolkit mechanisms required to build them. These interaction techniques each address problems not directly handled by standard approaches to mediation, and can all be re-used in a variety of settings.

Current context-aware services make the assumption that the context they are dealing with is correct. However, in reality, both sensed and interpreted context is often imperfect. In this paper, we describe an architecture that supports the building of context-aware services that assume context is imperfect and allows for the refinement of this imperfect context by mobile users in aware-environments. We discuss the architectural mechanisms and design heuristics that arise from supporting this refinement over space and time. We illustrate the use of our architecture and heuristics through two example context-aware services, an In-Out Board for the home and a situation-aware reminder tool.
