Reality of Ubicomp : many computers per person!

Computers at many levels of scale

What makes ubicomp design different (harder)?

Key differences

  • Multiple form factors (inch/foot/yard)

  • Network connectivity

  • “Context” awareness

  • Interface modalities

    Naïve “computerization” does not work!

Styles of design within ubicomp

  • Mobile

  • Ambient

  • Augmented

  • Tangible

  • Multi-device / Device Ensembles

  • Pen Computing

  • Speech Interfaces

How to approach Ubicomp design

  • User centered design especially important

  • The design of everyday things approach

  • The coming age of calm technology

  • Embodied virtuality

Designer’s Outpost

Design considerations vary depending on scale


  • Every pixel counts

  • Detail + Overview

  • Context Aware


  • Action at point of input

  • Error handling and disambiguation

  • Reduce requirement for recognition


  • Fluid interaction

  • Freeform input

  • Reduce requirement for recognition

Additional Ubicomp design considerations

  • Context (e.g., location in the real world)

  • Spatial or temporal multiplexed input

  • Capture and access

  • Privacy
