At present, these technologies are still expensive, though. becomes more and more common, the market is growing for biometric (生物测量) technologies—like fingerprint Researchers from Georgia Tech say that they have come up with a low­cost device (装置) that gets around this problem: a smart keyboard. This smart keyboard ， whether they should be given access to the computer it's connected to—regardless of whether someone gets the password right. measures the cadence (节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user's typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people's identities, and by It also doesn't require a new type of technology that people aren't already familiar with. Everybody uses a keyboard and everybody types differently. In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty and is mostly made of inexpensive, plastic­like parts. The team hopes to make it to market in the near future. to 1．Why do the researchers develop the smart keyboard? A. To reduce pressure on keys. B. To improve accuracy in typing. C.
