Scientists develop artwork that changes to suit your mood

Computer scientists from Bath and Boston have developed electronic artwork that changes to match the mood of the person who is looking at it.

Using images collected through a web cam, special software recognises eight key facial features that characterise the emotional state of the person viewing the artwork.

It then adapts the colours and brush strokes of the digital artwork to suit the changing mood of the viewer.

For example, when the viewer is angry the colours are dark and appear to have been applied to the canvas with more violent brush strokes.

If their expression changes to happy, the artwork adapts so that the colours are vibrant and more subtly applied.
