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
