     Imagine having a bedroom that interacts with you. If you're sad, it will arrange for some of your friends

to come over to cheer you up. If you're happy, it might respond by playing your favorite game with you.

     Does it sound like something out of a science-fiction movie? Well, it's really something out of the Georgia

Institute of Technology. Irfan Essa works at the computer lab there. He has developed a computer system

that can look at you and recognize your mood. He calls it the "expression recognition system." Essa says, "We

are trying to get computers to act like a human brain. But the human brain is not like one computer, it is like

many working together."

     In Essa's system, many computers work together. First, a camera in the bedroom takes a picture of your

face. The camera feeds the image to a computer. In the computer's memory, there are pictures showing how

the muscles of your face move when you are in different moods. For example, cheek muscles move in one

way when you are happy and smiling and in another way when you are nervous and tense. The computer

compares your picture to the face-muscle images stored in its memory. It tries to find the best match.

That's how it figures out your mood! Then the computer sends messages to other computers in the system.

If you look happy, a computer may put on lively music. If you look tired and discouraged, a different

computer may turn on the TV for you.

     How could the "expression recognition system" help us in important ways? Essa thinks that the system

can help us create computers that are better teachers. Many people learn new skills through computer

programs. "When I teach, I look at people's faces," Essa explains. "If my students look confused, I know

they didn't understand. With this technology, a computer canal-so know if a student is learning."

     Today, this new technology can be found only in labs, but Essa predicts we'll see it out of the lab in a

few years. So get ready. One day, you might walk into a room that will soon become your best friend.
