2013年职称英语考试完形填空必背解题技巧

　　Vibrating rubber cellphone could be the next big thing in mobile communications. They allow people to communicate by squishing the phone to transmit vibrations along with their spoken words. According to a research team at the MIT Media Lab in Cambridge. Massachusetts, the idea will make phoning more fun.

　　Many mobile phones can already be made to vibrate instead of ring when you do not want people to know you are getting a call. But these vibrations, caused by a motor spinning an eccentric weight inside the device, are too crude for subtle communication, says Angela Chang of the labs Tangible Media Group. Theyre either on or off, she says.

　　But when you grip Changs prototype latex cellphone, your fingers and thumb wrap around five tiny speakers. They vibrate against your skin around 250 times per second. Beneath these speakers sit pressure sensors, so you can transmit vibration as well as receiving it. When you squeeze with a finger, a vibration signal is transmitted to you callers corresponding finger. Its strength depends on how hard you squeeze.

　　She says that within a few minutes of being given the phones, students were using the vibration feature to add emphasis to what they were saying or to interrupt the other speaker. Over time, people even began to transmit their own kind of ad hoe Morse code, which they would repeat back to show they were following what the other person was saying. It was pretty easy to communicate, though we didnt specifically prearrange codes, says David Milovich, one of the students who tried out the device.
