Computer-human interaction can be weird. So maybe it's reasonable that some of the ideas on display at the recent Computer-Human Interaction 2009 conference were a bit strange too, or at least strange-looking.

Technology Review has a roundup here. A sampling:
--odd goggles that permit the user to control a computer with eye movements alone.
--communicating with a mouse via sensations of hot and cold.
--turtle-shaped photo-displaying clocks that, when synced, show related photos.
--a small robot that can trundle a cell phone around.
--a camera and mic embedded in a matchstick whose purpose I will not even try to describe.

But, trust me, it's weird.
