Vibrating Rubber Cellphones
Vibrating rubber cellphones could be the next big thing in mobile communications. They allow people to press the phone 1：o transmit vibrations along with their(51) words. According to a research team at the MIT Media Lab in Cambridge， Massachusetts， the idea will make(52) more fun.
Many mobile phones can already vibrate instead of ringing(53) you do not want people to know you are getting a call. But these (54) are too simple for subtle (敏感的) communication，(55) Angela Chang of the lab's Tangible Media Group. "They're either on or off，" she says.
But when you hold Chang's rubber cellphone， your fingers and thumb wrap around five(56) speakers. They vibrate (57) your skin around 250 times per second. Beneath these speakers sit pressure sensors (传感器)， so you can transmit vibration as well as(58) it. When you squeeze with a finger， a vibration signal is transmitted(59) your caller's corresponding finger， its speed (60) on how hard you squeeze.
Chang says that within a few minutes of being given the phones， students were using the vibration feature to(61) emphasis to what they were saying. Over time， people even began to transmit their own kind of ad hoc (特别的)"Morse code"， which they would repeat back to show they were(62) what the other person was saying.
Chang thinks "vibralanguages" could function for the same(63) as texting： sometimes people want to communicate(64) without everyone nearby knowing what they're saying. "And(65) actually being able to shake someone's hand when you close a business deal，" she says.
