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 , Stevcn 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 weanng a pair of Steven's glasses . all yau have to do is glance above the restauran’s doorway and your glasses will immediately become windows to the Tntemet, 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 provide 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 connected 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 fashionable as well as a useful application. A chemical engineer named Roben 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 scientiscs , 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 cheapcr.  Lhcy will pop up in all sorts
of easily-wearable accessories . even in the buttons on your coat.  WhaCs morc, this is something that's going to happen a lot sooner than we all expect.
