Wow, Ishii is still harping on about his tangible user interface? His work was very thought-provoking for new user interfaces, particular for ubiquitous computing, but his most relevant work was done about 6-7 years ago. It's a little sad it hasn't progressed much further... Admittedly the scales solution is pretty cool, a useful, cheap method for context awareness. A fellow PhD used a Lego mindstorms kit to detect which instrument was picked up in a surgical environment and update the patient record display accordingly. I suppose thought provocation is a good thing then... I'd just like to see something really useful (in the 'real world') come out of there.
