人腦撥號手機解放你的雙手
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。對我們這個寸時寸金的快節奏社會來說，打電話撥號碼似乎也是在浪費時間。對此美國研究人員已經找到解決辦法，他們研製出一種大腦撥號手機，不動一根手指，便能撥打電話。
用戶需要佩戴一個連接藍牙設備的特製頭部飾帶，通過該裝置向諾基亞N73手機發送無線信號，然後迴應大腦發出的信號。專家認爲經過練習，任何人都能掌握操作方法。
他們希望利用這項技術爲殘疾人，行動不便的老年人，以及高壓工作環境下的工作人員研製出更安全且不用雙手的手機。
根據赫芬頓郵報的報道，這項技術的研發者，加州大學聖地亞哥分校斯旺茲電腦神經系統學中心的科學家鍾子平表示，該設備通過戴在頭上的腦電波(EEG)電極來分析和確定人想法。他認爲，只要稍作練習，操作準確度就能達到100%。
使用者佩戴的腦電波裝置檢測出大腦發出的信號後，藍牙設備就會給手機發送指令。該技術利用演算法則處理信號。試驗過程中，研究人員在屏幕上以不同速度顯示從1到9的阿拉伯數字，讓使用者看，腦電波電極就會檢測到使用者大腦裏出現的相關信號。在最初進行的試驗中，參與者撥10位數的電話號碼的正確率達到70%到85%。儘管利用人大腦產生的腦電波操控電腦的技術已經出現一段時間了，但將這項技術應用到手機上，尚屬首次。
