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!

How to approach Ubicomp design
User centered design especially important
The design of everyday things approach
The coming age of calm technology Embodied virtuality
