Canadian helps severely disabled speak through music
Montreal, Canada (AFP) Oct 4, 2010
Children immured within their severely disabled bodies may soon be able to communicate thanks to a newly unveiled device that translates physiological signals into music.
Stefanie Blain studied for five years the interactions of children with severe disabilities and their parents, as part of her doctoral studies at Canada's largest children's rehabilitation hospital, Holland Bloorview, in Toronto.
"They can 'read' their children by observing minuscule movements of their lips, or changes in their breathing," she told a Technology, Entertainment, Design (TEDx) conference in Montreal.
By measuring those tiny physiological signals, Blain was able to show that Max, a 15-year-old adolescent who was seemingly in a vegetative state, became animated when he spotted his favorite toy.
Even completely paralyzed, the body continues to react by changes in body temperature and sweat levels, as well as heart and breathing rates, she explained.
Blain initially created a graphic translation of these physiological arousals.
"But my curves and 3D simulations didn't speak to anyone," she said with a smile. So, being a musician, she wrote algorithms to convert them into sounds," she said.
"Another child, whom we believed was always sleeping, started to emit a 'biological song' whenever clowns entered his room. It was the first time that his parents and hospital staff realized that he was conscious of the world around him," she said.
The software she created deciphers physiological signals and translates them into a range of tonalities, from soft low-pitched sounds when an individual is calm to high-pitched and more complicated tunes when they are thinking of pleasant things.
"Each 'song' is unique," she said.
"Imagine that when I arrived at the hospital, the hallways were quiet leading to the rooms of children who could neither move, nor speak, and not even make facial expressions," she said.
"Imagine these hallways now (full of music), imagine parents who can really get to know their children."
Currently, the research team lead by Tom Chau is seeking to expand the technology to make it possible for severely disabled children to answer yes or no when prompted, and use a computer.

The suicide rate among the elderly living in China's urban areas has become alarmingly high as they face rising medical bills and relocations from their homes, state media reported Tuesday. The annual suicide rate among those aged 70 to 74 in cities surged above 33 per 100,000 people between 2002 and 2008 compared to 13 per 100,000 people in the 1990s, the official China Daily quoted a socio ... read more
