“A computer programme enabling paralysed patients to create artwork using just the power of their brains drew big crowds on Wednesday at the CeBIT, the world’s top IT fair. Under a system pioneered by Austrian firm g-tec, the user wears a cap that measures brain activity. By focusing hard on a flashing icon on a screen, the cap can recognise the specific brain activity connected to that item, allowing the user to “choose” what he or she wants the computer to do. The artist can select various shapes and colours via brainpower and build up a basic picture on the screen, explained g-tec sales director Markus Bruckner. The user can also draw straight lines.”
