A team of computer scientists has developed artwork that changes itself to suit its audience?s mood. Maria Shugrina and Margrit Betke from Boston University, US, and John Collomosse from Bath University, UK, developed the video artwork display, which can display any kind of image, but will morph the colours used, in response to the expressions worn by the person looking on.

If the viewer looks angry it will apply a red hue and blurring. If, on the other hand, they have a cheerful expression, it will introduce increase the brightness and colour of the image.

The empathic painting consists of a video screen with a camera mounted on top. Video footage of whoever is standing in front of the pictures is then analysed by software, which measures 8 different facial aspects such as the position of their eyebrows and the shape of their mouth.

The software uses these features to plots an expression on a graph that rates arousal and sleepiness on one axis and pleasure and displeasure on another. Positions on the graph's axes are linked to graphical effects that reflect the appropriate emotions. So changes in a person's facial expressions are matched by smooth changes in the appearance of the picture.

Such paintings might one day be used to try and actually influence people's moods, but Collomosse says the team have not tried this yet.
