Spatial awareness not reliant on just sight

Our brain's understanding of spatial awareness is not triggered by sight alone, scientists have found. University researchers have found that our brain can use other senses - such as touch - to help us understand spatial awareness. The findings could help in designing technology for the visually impaired. Scans. Scientists took MRI brain scans of both sighted volunteers and others who had been blind since birth while they examined three-dimensional spaces. Both groups were first asked to feel three dimensional Lego models representing a geometric layout of a room and models of abstract objects containing no enclosed spaces. The sighted volunteers were then also asked to look at photographs of the same rooms and objects.
