Sterile gestural interface

A great example of smart interaction design: touch-free gestural interfaces for hospital displays:

“A sterile human-machine interface is of supreme importance because it is the means by which the surgeon controls medical information, avoiding patient contamination, the operating room (OR) and the other surgeons.” This could replace touch screens now used in many hospital operating rooms which must be sealed to prevent accumulation or spreading of contaminants and requires smooth surfaces that must be thoroughly cleaned after each procedure — but sometimes aren’t.

Interesting sidenote: the fact that we associate touch with contagion in our culture is encoded in the words we use. Contagion literally means “with touch.”
