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 to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated(展示)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.He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells.These send signals through the spinal cord(脊髓)to the muscles to give us the ability to move.But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says.“Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user.This head cover picks up the signals from the scalp(头皮)and sends them to a computer.The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path.They help the computer react to commands from the brain.
Prof.Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands.“The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices.One example is this wheelchair.”
He says his team has set two goals.One is testing with real patients, so as to prove that this is a technology they can benefit from.And the other is to guarantee that they can use the technology over long periods of time.

Would the voice of Amanda Holden saying “your city had talent” encourage you to use a litter bin? Or maybe former Monty Python star Michael Palin telling you no one had expected “the Spanish bin-quisition”?
Organizers of a plan persuading celebrities(名人)to lend their voices to “talking bins”believe it can make a real difference to keeping Britain tidy. They hope that by using humor, they will succeed where fines and warnings have failed in keeping streets and parks clean.
A similar experiment in Sweden found a talking bin received nearly three times as much rubbish as an ordinary one because people were attracted by its quality of being new and unusual value.
Twenty-five specially adapted bins to be installed(安装)in the streets of London and Liverpool next month will use a sound card to play a themed message when litter is placed inside. For example,one near the Royal Opera House will play a “thank-you” message sung by Janis Kelly to the tune of Nessun Dorina. Bins installed in Liverpool will play Beatles-themed messages. For others,Britain’s Got Talent judge Holden is expected to record the message:“This is Amanda, and this city’s got talent.”
The campaign,entitled Bin Thinking, is being organized by art group Sing London. If successful,talking bins could become a familiar feature on Britain’s streets.
Colette Hiller, director of Sing London, said, “ The idea is to reward people in a small way for changing their behavior and raise awareness through a sense of fun.”
