Gestural Interfaces

A good piece on gestural interfaces and some of their recent developments and applications. I have used everything from paper tape to light pens to the foot-mouse. Was a very early mouse user. Impressed by suggestions by the 'minority report' movie and the IPhone two-finger zoom. Have seen good demos for gestures in a collaborative war-room style space. Yet I have yet to see a really effective gestural interface for the kinds of things I do day-to-day. Still need a keyboard and irritated by touch interfaces in general. Convince me.
