    Brain painting

    Brain Painting: Painting just by thinking!

    Brain Painting (www.brainpainting.net) is a research project aiming at assisting paralysed people in “locked-in” state who, due to neurodegenerative diseases like Amyotrophic Lateral Sclerosis (ALS), are severely restricted in communication with their environment. With Brain Painting, they can finally express their emotions, creatively communicate and finally be perceived by their environment as communicating personalities.

    The Brain Painting software uses brain activity as a control signal for a painting application with a non-invasive connection between brain and computer, a so called “brain-computer interface (BCI)”. The BCI enables a communication and control without any muscular pathways.

    To enable the brain to control, the user is wearing an EEG (electroencephalography)-cap with electrodes that are connected to an amplifier, and painting items flash in column and rows in the so called “P300-Matrix” (Figure 2). The P300 is a positive deflection in the electric activity of the brain that occurs when the user focuses on an infrequent stimulus (odd) that occurs in a sequence of frequent stimuli. By selecting a painting colour on the P300-matrix, the user “prints” the painting on a second monitor, the “digital painting canvas”.

    The research project Brain Painting was started in the mid-2000ies by Andrea Kübler[[1]] (University of Würzburg, Institute of Psychology in Germany) and enhanced since 2012 with her team[[2]][[3]][[4]][[5]] within a European research project ("BackHome" (FP7-ICT-288566)). The focus of this further Brain Painting is to optimise the software an independent use at home.

    Since then, two locked-in ALS-diagnosed artists are using Brain Painting on a regular weekly basis and independently at home. Not only their quality of life is tremendously increased, but also their self-esteem enhanced. Brain Painting is a revolution for such injured people, just as one of them says: “Brain Painting is like Sunday breakfast for the soul” (Heide Pfützner – artist name)!

    Heide Pfützner, ©HHEM, already exposes for the 1st time her paintings in Germany at the VR-Bank FORUM in Würzburg – Marktplatz 2 Mo-Fr 9 am – 5 pm. (Free entry).
