Virtual Faces With Personality And Emotion

The faces of virtual characters can be generated from a model with defined personality traits and matching emotions. This research project has been conducted at the Computer Graphics and Vision Group (UIB), a research unit of the Mathematics and Computer Science Department at the University of Balearic Islands.

The researchers followed the five-personality-trait model developed by Albert Mehrabian; extraversion, neuroticism, openness, conscientiousness and agreeableness all reflect associated facial expressions.

"This paper presents an affective model that determines the emotional state of a character according to the personality traits and the experienced emotions. We consider an emotional state as the layer between personality and emotion. The proposed affective model offers a mapping between emotions and emotional states. To evidence emotional states of a virtual character, we can attribute them facial expressions based on their associated emotions. Facial expressions for intermediate emotions are generated automatically from expressions for universal emotions. The experiments show coherent emotional states produced by a simulated story. They also present how the corresponding emotions were represented through dynamic and static facial expressions. Finally, the obtained results demonstrate the satisfactory recognition by a group of people unfamiliar with the work described."

SF fans are looking forward to virtual characters with real emotions and personalities. Trek fans recall Landru, the computer that ran a planet.


(Landru)

Fans of written sf recall characters like Wintermute, who appeared to Case in cyberspace as an old friend and associate.

Case brought the gun around and looked down the line of sight at Deane's pink, ageless face.

`Don't,' Deane said. `You're right. About what this all is. What I am. But there are certain internal logics to be honored. If you use that, you'll see a lot of brains and blood, and it would take me several hours -your subjective time -to effect another spokesperson. This set isn't easy for me to maintain. Oh, and I'm sorry about Linda, in the arcade. I was hoping to speak through her, but I'm generating all this out of your memories, and the emotional charge... Well, it's very tricky. I slipped. Sorry.'

Case lowered the gun. `This is the matrix. You're Wintermute.'

`Yes. This is all coming to you courtesy of the simstim unit wired into your deck, of course. I'm glad I was able to cut you off before you'd managed to jack out.' Deane walked around the desk, straightened his chair, and sat down. `Sit, old son. We have a lot to talk about.'
