Afterwards I passed through the old department and saw a couple of foldable tables which might be nice to make a semi-portable reatavision table.
Got to thinking about making a multi-touch surface using a projector against a large sheet of glass with tracing paper as the projection surface. Could we track fiducials in the IR from behind the glass. The problem is that the markers would not 'sick' to the vertical surface. Useful for manipulation but not objects.
I'm wondering what kind of interface I could build with that - perhaps something for NATS.
Jeff said something quite profound - we should stop thinking about technologies and think about user studies.
I also worked on the audio interface as a relax/quickie paper. I think I have enough voices for a run through.
