• 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
ActivityStudio

• 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

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?
