- 14. Great Unified InputTheory • iStuff wireless hardware layer can be RF, X-10, Bluetooth, 802.11b, Infrared, Cellular,... • Offer iStuff as abstraction layer of room devices above this level • Adopters can – Use our hardware and software designs and replicate devices – Use our software and use off-the-shelf
- 15. Summary • The StanfordiRoom • Ubicomp requires re-thinking user interface metaphors and architecture • iStuff as a tool to facilitate experimentation in ubicomp interfaces – Not the answer to "post-desktop mouse & keyboard", but may help finding it... • http://iwork.stanford.edu/ • http://www.stanford.edu/~borchers/iStuff/
