The end of dialling? Mobile phones powered by the mind take hands-free to a new level
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 per cent accurate with just a bit of training.
He said: 'From our experience, anyone can do it.'
Users wear an EEG headband, like the one pictured above, 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 per cent 85 per cent 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.
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。TAG标签： 研究人员 研制 不用手 动脑 拨打手机
