Digital avatars are still pretty robotic in their motions and expressions. A team of researchers from the Autonomous University of the State of Mexico are working to give computers more personality.
The team worked with volunteers and on each one, attached tactile sensors to the 43 muscles involved in facial behavior. The sensors released tiny electrical pulses to provoke different gestures and then the scientists captured those movements with a 3-D camera.
The data was combined with a computer model designed to animate the expressions and gestures of the virtual characters in situations of happiness, sadness, surprise, fear, anger and disgust.
