     A Northern Ireland team is leading a research to develop a thinking computer which can

sense a user's mood.Researchers at Queen's University in Belfast hope to complete the 10

million Euro project for an emotionsensitive computer within four years.

     The aim is to enable computers to think and behave more like humans.The Europewide

project is being led by the university's School of Psychology and involves 160 researchers

from 27 institutions.The university's researchers developed the scheme and signed the

contract with the European Commission.The academics said the work will build upon attempts

to create "multimodal interfaces (多模式界面)" which allow machines to sense and respond

to the moods of the user.

     Programme leader Professor Roddy Cowie said while it sounds like science fiction, computers

which respond to human emotion will appear in the future."At the moment, our use of computers

is limited by the fact that we need a keyboard and a screen to access them," he said."It would make

a big difference if we could interact with them by speaking normally-perhaps through a microphone

and a transmitter (传感器)." But emotion is part of normal speech, and experience has shown that

most users are deeply uncomfortable with speech interfaces that ignore it-too uncomfortable to use

them very much."If we can make computers more intuitive (富于直觉的) and expressive, and also

less challenging to use, there is great potential to let people make fuller use of information technology."

     The emotionsensitive computer would have its own "personality" and establish a social relationship

with the user."It's a fair bet that in 30 years' time, emotionsensitive interfaces will be as much part of

life as windowandmouse interfaces are now," said Professor Cowie.The project team believes such

computers will play a major role in teaching and learning.
