2. Overview The ideal The more realistic (our goal) Our group motto “If at first we don’t succeed, redefine success!” What we will be able to demo Four sources of second hand information is not better than the original

3. Ideal All machines can communicate with one another seamlessly. All machines can sense our thoughts and are able to download the information we want automatically to our brain. Obviously, we are not idealistic.

4. The more realistic Build infrastructure to allow apps on any device to have access to the user’s info. Data moves with the user Users wear small keys/tags/badges to identify themselves Data possibly cached in these keys/tags/badges for maximum performance.

5. If at first we don’t succeed… SpotON not the best choice for location/identity tags Range and precision limited Not small, no caching Alternative was discovered too late Drop a platform – Palm (unless someone is really bored this weekend) Drop two applications – We’re supposed to get 3 rd party vendors anyway ;-)

6. The Demo Scenario: User walks up to iPAQ, opens ToDo application. His/her information automatically is loaded. He/she modify the information, goes to the video wall. The changes are displayed there. All planets must be aligned correctly. Actually WinCE, Windows, and 802.11 on the iPAQ must all work. Don’t know which is harder.

7. Details – SpotON server It works fine, but …. Not the best reliability or performance SpotON tags are a hassle Only 3 tags available on Demo day  No dedicated IP for this right now Background app to communicate with SpotON server and each application. Artefacts of demo

8. Details – Profile Server Works great Currently supports Instant Messenger, MemoPad, and ToDo applications Each application communicates individually with server Maintains connection during life of app

9. Details – Applications All three applications work fine under both WinCE and Win98/2000. “If it works, don’t push your luck.” Contact List condition – possible Resurrecting the Palm platform? Well, it’s hard to resurrect something that never lived in the first place.
