Increasingly over the last few years, we have become familiar with the range of small electronic devices
or "smart" accessories (附件, 饰品). Pocket heart-rate monitors for joggers and electronic maps are just the
first examples of many new products that promise to change our lives in all sorts of surprising ways.
As a scientist at New York University, Rosalind Picard tries out different smart accessories before they
go on the market. One of these was the so-called "frown (皱眉) headband". Rosalind was shocked to realize
just how often she frowned stuck in a traffic jam recently, Rosalind kept hearing the sounds of the tiny sensor
inside the band worn around her forehead-each time she frowned in annoyance, the sensor gave out a signal.
Another computer scientist, Steven Feiner, is working on a pair of glasses that will do more than help you
to see. Imagine you want to try a restaurant in a foreign city but you're not familiar with the dishes on the
menu. If you are wearing a pair of steven's glasses, all you have to do is glance above the restaurant's doorway
and your glasses will immediately become windows to the Internet, offering you full details of the meals served
inside. The glasses could also be used to help people make speeches, give chefs access to the latest recipes
and even procide doctors with patient information while they carry out operations.
At the moment, steven's invention looks more like a large ski mask than a pair of glasses. It's a headset
collected to a hand held computer and a Global Positioning System (GPS) receiver, which tracks the wearer's
position. But he says that these head-worn displays will eventually get smaller and lighter as technology
improves.
And, of course, this new technology has a fashiomble as well as a useful application. A chemical engineer
named Robert Langer has invented a new microchip that, if put inside a ring, can give off different smells
according to a person's mood. That, of course, may or may not appeal to you. And, in the end, it is shoppers
not scientists, who will determine which of these smart accessories will succeed as fashionable items and
which are sure to join history's long list of crazy inventions.
It is clear, however, that as computers get smaller and cheaper, they will pop up in all sorts of easily-
wearable accessories, even in the buttons on your coat. What's more, this is something that's going to happen
a lot sooner than we all expect.
