A native of Sydney, Australia, and a professor of computer science at Stanford since 1982, Pratt and others in the wearable-computing business aim to build very small, yet very powerful PCs that people will carry around with them and put to work in many ways. Such computers might be slipped into shirt pockets, or sewn invisibly in clothing. Or they might become fashion accessories, hooked on belts or key chains, strapped to arms, embedded in jewelry, watches and glasses. If wearable computers get popular, Pratt says, some manufacturers will surely make them fashionable and attractive, much as Apple has recently found new success by paying attention to aesthetics. So you use your computer to call up the latest ratings.
