Say goodbye to unproductive minutes spent waiting in line
Worried about unproductive minutes spent, say, waiting in line at the grocery store or riding home on the bus? You could soon be outfitted with a virtual keyboard that would allow you to type anytime, anywhere. The prototype, created at the University of California, Berkeley, employs 10 minuscule silicon chips glued to your fingernails that track your fingers’ movements on an invisible keyboard, reports Shift (April 2000). The information is then transmitted to a processor via low-power radio waves. Back at the office, that memo is done.
