人脑拨号手机解放你的双手

　　It seems even dialling a mobile number is becoming too time consuming for our fast-paced time precious society. But researchers in America have come up with a solution - a mobile phone which uses the power of thought to make a call - and you do not have to lift a finger。

　　Users wear a specially designed headband which is hooked up to a Blue tooth device that wirelessly sends commands to a Nokia N73 mobile phone. The technology works by responding to cues from the brain and experts believe anyone with training will be able to master the technique。

　　It is hoped the break-through will be able to create safer hands free mobile phones to help the disabled and elderly and help out professionals in high pressured working environments。

　　According to the Huffington Post, developer Tzyy-Ping Jung, a scientist at the Swartz Center for Computational Neuroscience at the University of California, San Diego, said the device relies on electroencephalogram (EEG) electrodes on the scalp to work out what the brain is trying to say. He believes it could be 100 percent accurate with just a bit of training。

　　Users wear an EEG headband, which detects brain signals and a Bluetooth gadget sends instructions to the phone. This uses algorithms to process the signals. During trials, users were shown digits from zero to nine flashing at different speeds on a screen and this was detected by the electrodes. Those used in the initial experiments were between 70 percent 85 percent accurate when trying to dial a 10 digit phone number. Thought powered computers have been around for a while, however this is the first time it has been adapted for mobile phones。
