Hudin:
Yes Paul, a friend of mine whom we grew up together is actually blind and that's why I opted for this as my final year.
Good for you! I asked because my college(so many years ago!) math and physics prof was blind since age 15. I was also his assistant for a year. I never saw him have a problem with which room he was in either at home or at school. He did have his dog to guide him, so perhaps that was the difference.
I wish you great success with your project!
Paul
