Software that contorts an image of a person’s face to express different emotions could enrich text-based internet chat. The researchers behind the system say it can quickly transform a user’s face to convey any of six emotions, ranging from anger to happiness.
A user first uploads a picture of their face with a “neutral” expression. Then they use their mouse to mark the ends of their eyebrows, the corners of their mouth and the edges of their eyes and lips. The software uses these points to morph the face to express different emotions: happiness, sadness, fear, anger, surprise, and disgust. A user can select an emotion and one of three intensity levels when using the system.
