Computers help humans with a lot of things, from searching information to math. Now, they may be able to help us in more complex (复杂的) ways. Recent research has showed a new computer program that can recognize (识别) human emotions (情感), simply based on how they type.

Researchers from the Islamic University of Technology in Bangladesh asked a group of people to type two paragraphs from Lewis Carroll’s novel Alice in Wonderland. The participants (参与者) then chose an emotional state they felt while typing. Emotions tested were joy, fear, sadness and shame.

Then the researchers put the text into the computer to study. Surprisingly, the computer was right 70 percent of the time in telling the participants’ emotional states. The most correct emotions it guessed correctly were joy (87 percent) and anger (81 percent). The least correct emotion the computer guessed was sadness (60 percent).

However, the computer program is limited (局限) in what it can do. But scientists believe that it will help humans in the future.

“If we could build any program that is intelligent enough to communicate with humans that involved (含有) emotions…then using machines could be more effective (有效的) and friendly,” the researchers wrote in the 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 type of computer program could also help humans in a number of ways. First, with online teaching, emotionally intelligent computers could change its teaching style or content (内容) to help students learn better. Second, with online conversation, doctors could be able to tell the emotion of a patient.
