Digital art that responds to emotional state
August 4, 2006David Pescovitz: Computer scientists have created a digital artwork that changes based on the mood of the viewer as expressed in his or her face. A webcam tracks eight facial features and then changes the digital image in response. The researchers from the University of Bath and University of Boston University call the technique “empathic painting.”
From a press release:
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…
“The programme analyses the image for eight facial expressions, such as the position and shape of the mouth, the openness of the eyes, and the angle of the brows, to work out the emotional state of the viewer,†said Dr John Collomosse from the Department of Computer Science at the University of Bath.
“This kind of empathic painting only needs a desk top computer and a webcam to work, so once you have the programme and have calibrated it for the individual viewer, you are ready to start creating personalised art based on your mood.
“The empathic painting is really an experiment into the feasibility of using high level control parameters, such as emotional state, to replace the many low-level tools that users currently have at their disposal to affect the output of artistic rendering.â€
