Resumen de OK computer
Campbell talks about gestural computing. The first computers able to recognize human gestures emerged in the 1970s, when researchers equipped people with batons or wearable accelerometers. The crude resolution of these technologies stopped them taking off. Still, limited bodily gestures in two dimensions were incorporated into personal computers: using a mouse to drag a scroll bar or double-click on a desktop icon required a physical motion with the hand and arm, rather than typing code. Until very recently, however, most hand and body language was invisible to computers.
