New, innovative forms of treatment for blind people are now a possibility following new research into spatial awareness, it has been claimed.
Dr Thomas Wolbers, from the University of Edinburgh's Centre for Cognitive and Neural Systems, worked on a new study which has found that people do not only estimate their surroundings through sight alone.
He explained: "Touch plays a role in our understanding of spatial awareness in the same way that we rely on our sense of sight. There is no reason why other senses, such as sound, would also not have the same effect."
According to the expert, the findings may help to develop technologies to help visually impaired people, such as sensors that can measure spaces and convey information to the brain through vibrations.
Meanwhile, specialists at Columbia University Medical Center recently revealed they are at work on a new cure for age-related macular degeneration, one of the leading causes of blindness on the planet.
