Blind man navigates obstacle course using 'blindsight'

A man who was left completely blind by multiple strokes has been able to navigate an obstacle course using only his "sense" of where hazards lie. Brain scans showed that he could recognise expressions including fear, anger and joy in other people. However, he is totally blind and normally walks using a stick to alert himself to objects in his path. To test the extend of his blindsight, scientists constructed an obstacle course made up of boxes and chairs arranged in a random pattern. Not only was he able to safely manoeuvre the course he did not bump into a single box or chair.
