IDENT’s GestIC technology is a gesture-based interface system and they’re showing off by describing a cube of some sort that allows you to turn, twist, and pinch your data in 3D. Each side will have different functions and you can access messages and the web just by slipping and sliding on the surface.
This is obviously as real right now as the Yeti but you could imaging something like the iPad in 3D with touchscreens on each surface. It also looks quite striking and the interface is great if you’re into high-tech Minority Report stuff. Why you’d want this instead of something that fits in your pocket is beyond me, but there’s no accounting for taste.
GestIC is described as a new HCI method and has already shown up in some devices. You can read more about the cube here.
