Computers may be able to help us in more complex（复杂的）ways. Recent research has showed a new computer program that can learn human emotions.
Researchers asked a group of people to type two paragraphs from Lewis Carroll's novel Alice in Wonderland. The people then chose an emotional state they felt while typing. Moods（情绪）tested were joy, fear, anger, sadness, disgust, shame and guilt. Then the researchers put the text into the computer to study. Surprisingly, the computer was right 70 percent of the time in telling their emotional states. The most correct emotions it guessed correctly were joy (87 percent) and anger (81 percent). The least accurate emotion the computer guessed was sadness (60 percent).
However, the computer program is limited（局限的）in what it can do. But scientists believe that it will help humans in the future.
" If we could build any system that is intelligent enough to communicate with humans that involved（涉及）emotions…. Then using machines could be more helpful and friendly, " the researchers wrote in study. For example, when looking for a movie online, perhaps a computer program could make suggestions for films that would match your mood. And as the researchers said, this kind of computer program could also help humans in a number of ways. First, with online teaching, emotionally intelligent computers could change its teaching style to help students learn better. Second, with online talking, doctors could be able to tell the emotion of a patient.
