Computer scientists at the University of Bath, in collaboration with the University of Boston have developed software that creates images that changes according to the mood of the person looking at it. The program uses facial recognition techniques to analyse images from a webcam, observing the person looking at the screen. It recognises eight key facial features, which are then used to control the colours and brushstrokes of the digital artwork appearing on the screen. If the viewer’s expression changes then so to does the mood of the image. No word yet on what it’s going to be used for but the work is part of an ongoing research project to develop a range of advanced tools for the computer graphics industry.
