I’ve seen this presentation but this time my attention was drawn towards the Open Source version of Google Earth made by NASA. The title was a little obscuviated but I beliefe it’s “WorldWind” http://worldwind.arc.nasa.gov/
The problem with all these researchers into UIs is they have a distinct talent for ignoring what people actually use computers for, and what makes people use computers.
Various ones have completely ignored pictures as “irrelevant distractions”, and now we’ve swung to the reverse, where actually a really simple way to send and search through email is what people need, not some shiny way to organise their photo library, which is nice, but the Wii and iPhoto are basically already there.
