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 band. He could even talk as he watched the vehicle and guided it with his thoughts.
"Our brain has billions of nerve ceils. 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.

Do you live in a happy country Chances are strong that you do. Results of a recent study have shown that many people around the world are happier now than in the past. The study is called the World Values Survey. Researchers responsible for the study are based at the University of Michigan Institute for Social Research in the United States.
The researchers gathered information from opinion studies done in more than ninety countries or territories. Those studies were completed between nineteen eighty-one and two thousand seven. University of Michigan political scientist Ronald Inglehart directed the World Values Survey. Mister Inglehart says the results surprised him. He said it is widely believed that it is nearly impossible for happiness levels for a whole country to improve. He said many earlier studies have suggested that happiness levels do not really change.
Denmark was found to be the world’s happiest country. Mister Inglehart notes that Denmark’s health care is good and few Danes are hungry. Zimbabwe was rated as the least happy country. Zimbabweans have suffered from political and social unrest.
Other nations in the top ten for happiness include Iceland, Switzerland, the Netherlands, Canada and Colombia. Colombia suffers from violence in some areas. But Mister Inglehart says Colombians share strong family, friendship and religious ties. He says those qualities are common in areas along the Caribbean Sea. And he says they help balance economic and political weakness.
The researchers compared the most recent World Values Survey with information from a study completed in nineteen forty-six. Several areas showed rising happiness levels. They include India, Mexico, Northern Ireland, Puerto Rico and South Korea.
Over the years, India’s economy has grown. An improved financial situation is an important sign of happiness, the political scientist says. But living in a country that is becoming more democratic may be more important. So may acceptance of minorities. Mister Inglehart says the study shows a strong link between happiness and freedom to choose how life is lived. It shows that equality between men anti women is another reason.
Mister Inglehart says Northern Ireland is doing well financially and moving toward sexual equality. He also says the area has the traditional bases of friendship, family ties and religion. Northern Ireland has suffered violence in the past. But he says most people there live a normal life today.
Some places showed less happiness than in the past. They were Austria, Belgium, Britain and the former West Germany. However, Mister Inglehart says these areas were still in the top twenty-five percent for happiness last year. And, he says that rating still shows a good level of satisfaction.
Which country is the happiest country in the world according to World Values Survey

A:Iceland. B:Switzerland. C:Canada. D:Denmark.
