　　QuesUons{下列各题}are based on the following paassage

　　Whether striding ahead with pride or slouching (没精打采地站) gloomily, we all broadcast our emotions through body language.Now a computer has learned to interpret those unspoken cues as wellas you or I.

　　Antonio Camurri of the University of Genoa in Italy and colleagues have built a system which usesthe depth-sensing, motion-capture camera in Microsoft's Kinect (体感游戏机) to determine the emotionconveyed by a person's body movements.Using computers to capture emotions has been done before, buttypically focuses on facial analysis or voice recording.Reading someone's emotional state from theway they walk across a room or their posture as they sit at a desk means they don't have to speak orlook into a camera

　　"It's a nice achievement," says Frank Pollick, professor of psychology at the University of Glasgow,UK."Being able to use the Kinect for this is really useful."

　　The system uses the Kinect camera to build, a stick figure representation of a person that includesinformation on how his head, torso (躯干) , hands and shoulders are moving.Software looks for bodypositions and movements widely recognized in psychology as indicative of certain emotional states.For example, if a person's head is bowed and their shoulders are drooping (下垂) , thatmight indicate sadness or fear.Adding in the speed of movement--slow indicates sadness, while fastindicates fear--allows the software to determine how someone is feeling.In tests, the systemcorrectly identified emotions in the stick figures 61.3% of the time, compared with a 61.9%success rate for 60 human volunteers.

　　Camurri is using the system to build games that teach children with autism (自闭症.to recognize andexpress emotions through full-body movements.Understanding how another person feels can bedifficult for people with autism, and recognizing fear is more difficult than happiness.

　　"In one of the serious games we developed, a child is invited to look at a short video of an actorexpressing an emotion," Camurri says."Then the child is invited to guess which emotion was expressed in the video." He adds that you can also ask the child to express the same emotion justby moving her body; joy, for example, can be characterized by energetic, fluid movements and atendency to raise your arms.

　　The team also plans to use the system to figure out how "in tune" a group of people is with their leader, looking for signals like how people's heads move when someone is speaking. Pollick says it could be useful as an automatic way to classify emotion--as part of a CCTV(闭路电视)system to infer intent, or to help shops understand customers.

　　57What is the advantage of the newly-developed system over previous research?

　　A.In tests it identified a person's emotion more correctly.B.It uses Microsoft's Kinect in a better way.

　　C.Itdoes not require a fixed position in front of a cameraD.It represents a person in a more detailedand vivid way.

　　58What body movements would the system probably interpret as sadness?

　　A.Bowed head and droopingshoulders.B.Energetic movements and a tendency to raise arms.

　　59What benefit can the serious games probably bring to children with autism?

　　A.They can learn how tomove their bodies.B.They can grow into an actor or actress.

　　C.They can be better understood bypeople.D.They can separate happiness from joy.

　　60What does the plan of Camurri's team imply?

　　A.The way a person's head moves suggests his attitudetoward the speaker.

　　B.The system can improve the relationship between leaders and group members.

　　C.Aspeaker should look for the signals given by the audience.

　　D.Listeners should pay attention to thetune of the speaker.

　　61What does Pollick think about this system?

　　A.It enables shops to better monitor customers.B.It hasa wide range of potential applications.

　　C.It is more useful than previous research.D.It can divideemotion states into different types.
