Gaudi Nanda sees a wearable computer as a handbag --- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded (嵌于) in it. It looks, feels and weighs like your typical leather purse.
That's where the similarities end: this bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you take an umbrella. This purse can even upload your favorite songs onto your scarf.
Surely, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. Dupont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty (耐磨损的) cycle.
As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $ 150, which is the price of an average leather purse.
Here's how the bag works: You place a special radio-signal-transmitting chip onto your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go.
Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring - and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years - making for a booming market for wearable computers that don't look like something out of science fiction.

The following are the results of the tests done by “Family and Home Magazine” on some Pocket Tape-Recorders on the market now.
Pearlcorder S702 $64
This simple model at the bottom of the Olympus range scored the most points for its excellent quality of recording. Background noise hardly affects the sound and recording from a pocket is perfectly possible, but it doesn’t turn off automatically.
Tape length: 30minutes per side. Weight: 240g.
Sony M9 $49.95
Small and very good looking, Sony’s latest offering scored most for its appearance. Sounds clear, but there is slight machine noise. The big control buttons are a great improvement on some of the complicated little controls on other tape-recorders. It doesn’t switch off automatically, but a red light shows if the machine is still running.
Tape length: 60minutes per side. Weight: 195g.
Sony M400 $115
Lots of little control buttons that make a noise are difficult to use. Recording is good but machine noise loses points. Tape counter and automatic switch-off when tape has finished recording or rewinding are useful.
Tape length: 60 minutes per side. Weight: 230g.
Imperial OEM MC7 $ 29.95
Cheap and simple compared with the rest, but recording is good as long as there is no background noise. Use only its own-make of cassette. No light to show it is on; no fast-forward button and the record button makes a loud noise.
Tape length: 30 minutes per side. Weight: 285g.
Philips 585 $80
Handsome and simple to use, but recording is very poor at more than the recommended distance of 5 cm-designed for dictation. No recording light.
Tape length: 15 minutes per side. Weight: 220g.
