     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.
