Since the 1970s,scientists have been searching for ways to link the brain with computers.Brain-computer interface (BCI) technology could help people with disabilities send commands(指令)to machines.
BCI定義
BCI(Brain-computer-Interface),即腦機接口是一種不依賴于正常的由外圍神經(jīng)和肌肉組成的輸出通路的通訊系統(tǒng)。
   BCI是一種連接大腦和外部設(shè)備的實時通信系統(tǒng),它可以把大腦發(fā)出的信息直接轉(zhuǎn)換成能夠驅(qū)動外部設(shè)備的命令,并代替人的肢體或語言器官實現(xiàn)人與外界的交流以及對外部環(huán)境的控制。
   BCI的實質(zhì)為通過腦信號推斷人的想法或目的,從而實現(xiàn)人機交流。
Recently,two researchers,Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne,Switzerland,showed us a small robotic wheelchair directed by a person's thoughts.
    In the laboratory,Tavella operated the wheelchair just by thinking about moving his left or right hand."Our brain has billions of nerve cells(細胞).These send signals through the spinal cord(脊髓)to the muscles to give us the ability to move.But some injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says."①Our system(系統(tǒng))allows disabled people to communicate with outside world by controlling the machines with thoughts."
    ②The researchers designed a special cap for the user.It picks up the signals from our brain and sends them to a computer.The computer gets the signals and starts to command the wheelchair after a short while.
    Prof.Millan,the team leader,says scientists keep improving the computer software that gets brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds:communication and controlling machines.One example is this wheelchair."
    He says his team has set a main goal.That is to test with real patients in order to prove(證明)that this is a technology they can benefit from.

(1)What can BCI help the disabled do?
It can help the disabled send commands to machines.
It can help the disabled send commands to machines.

(2)How did Tavella operate the wheelchair?
Just by thinking about moving his left or right hand.

我們的系統(tǒng)允許殘疾人用思維控制機器的方式與外界的溝通。

(4)請將文中②處劃線句子改為被動語態(tài)。
A special cap was designed for the user by the researchers.
A special cap was designed for the user by the researchers.

(5)Why will Prof.Millian's team test their products with real patients?
To prove that this is a technology they can benefit from.
