[Night Sundial] Orrery Clock

Something like this. But it should be much much simpler.

[Coin Throw] Multi touch Screen with IR sensors

By Mustafa Bagdatli (ITP researcher?)

Based on FTIR (frustrated total internal reflection) technology

Tom Igoe talked about this at the camp session.
Overkilling for my case perhaps, but I’d like to know.

[Night Sundial] Where to face?

I begin to realize that designing Interactive Sundial is a huge challenge in many ways.

I might think of doing a very simple presentation at the ITP camp.

[Night Sundial] Sundial Research

Sundials and Latitude
- The key is to put the pole parallel to the earth’s rotating axis.

Time, Stonehenge and Sundials

http://www.realestate3d.com/gps/latlong.htm

Suggestion from ITP camp sessions:
- Simulate sundial under the lack of lights (photocell detection)
- Change the structure to show sundial of different cities.. (Need to do research on the sundial changes by latitude / longitude difference)
- Show More interesting shadow

Some other solution I thought of, not to bore people, when showing the concept
+ Simulate time a bit faster (Run a fake digital clock by it. that fast forwards time)
+ Incorporating the city idea, maybe together with “Google map”, user click on the map, get the longitude/latitude live, then move the solar path into correct position to simulate it.

Questions remaining:
- How to incorporate the solar path?
- Two sides for date and night?
