University of Washington Yang LiDUB Group • activity-based ubiquitous computing • structuring ubicomp technologies and representing interaction contexts • exploring tool support for activity-based ubicomp • sketch-based user interfaces • pen-based interaction technique design • sketch parsing & demonstration
Current FocusTool Support for Exploring Activity-Based Ubicomp • analyze & design • based on collected field data • rapidly model & prototype • human activities • interactive behaviors • easily test a design • Wizard of Oz or sensors • facilitate deployment process • realistic & longitudinal studies ActivityStudio
Relation to Reality-Based Framework • design interactions based on what people naturally do • provide tool support for exploring, prototyping and testing new ideas • use sketch-based user interfaces as another case of reality-based interactions • two issues • leverage knowledge at different levels? • operational level, e.g., automated skills of switching on a light • action or task level, e.g., knowledge of making coffee • activity level, e.g., awareness of social structures • inform how interaction computing should be structured?
