　　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 words. According to a research team at the MIT Media Lab in Cambridge， Massachusetts， the idea will make more fun.

　　Many mobile phones can already vibrate instead of ringing you do not want people to know you are getting a call. But these are too simple for subtle communication， Angela Chang of the labs Tangible Media Group. Theyre either on or off， she says.

　　But when you hold Changs rubber cellphone， your fingers and thumb wrap around five speakers. They vibrate your skin around 250 times per second. Beneath these speakers sit pressure sensors ， so you can transmit vibration as well as it. When you squeeze with a finger， a vibration signal is transmitted your callers corresponding finger， its speed on how hard you squeeze.

　　Chang says that within a few minutes of being given the phones， students were using the vibration feature to emphasis to what they were saying. Over time， people even began to transmit their own kind of ad hoc Morse code， which they would repeat back to show they were what the other person was saying.

　　Chang thinks vibralanguages could function for the same as texting： sometimes people want to communicate without everyone nearby knowing what theyre saying. And actually being able to shake someones hand when you close a business deal， she says.
