揭秘：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。

　　对我们这个寸时寸金的快节奏社会来说，打电话拨号码似乎也是在浪费时间。对此美国研究人员已经找到解决办法，他们研制出一种大脑拨号手机，不动一根手指，便能拨打电话。

　　用户需要佩戴一个连接蓝牙设备的特制头部饰带，通过该装置向诺基亚N73手机发送无线信号，然后回应大脑发出的信号。专家认为经过练习，任何人都能掌握操作方法。

　　他们希望利用这项技术为残疾人，行动不便的老年人，以及高压工作环境下的工作人员研制出更安全且不用双手的手机。

　　根据赫芬顿邮报的报道，这项技术的研发者，加州大学圣地亚哥分校斯旺兹电脑神经系统学中心的科学家钟子平表示，该设备通过戴在头上的脑电波(EEG)电极来分析和确定人想法。他认为，只要稍作练习，操作准确度就能达到100%。

　　使用者佩戴的脑电波装置检测出大脑发出的信号后，蓝牙设备就会给手机发送指令。该技术利用演算法则处理信号。试验过程中，研究人员在屏幕上以不同速度显示从1到9的阿拉伯数字，让使用者看，脑电波电极就会检测到使用者大脑里出现的相关信号。在最初进行的试验中，参与者拨10位数的电话号码的正确率达到70%到85%。尽管利用人大脑产生的脑电波操控电脑的技术已经出现一段时间了，但将这项技术应用到手机上，尚属首次。
