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.
The project forms part of on-going research looking to develop a range of advanced artwork tools for use in the computer graphics industry.
This has already resulted in software which produces highly-detailed artistic versions of photographs, and allows designers to create animations directly from digital footage.
“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.
“It does all of this in real time, meaning that as the viewer’s emotions change the artwork responds accordingly.
“This results in a digital canvas that smoothly varies its colours and style, and provides a novel interactive artistic experience.
“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.”
The empathic painting project was carried out with Maria Shugrina and Margrit Betke from the University of Boston.
The images used in the project were created by the researchers using advanced artistic rendering techniques which give the computer-generated artwork the appearance of having been painted onto canvas.
More information on the empathic painting project, including a video demonstration, is available on the project website (see related links section).
The research was recently presented at the fourth International Symposium on Non-Photorealistic Animation and Rendering (NPAR) conference in Annecy as part of the International Animation Festival.

AI implications: Engineer's model lays groundwork for machine-learning device

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
