Found the video below demonstrating the fact that people can’t walk (drive or swim) in a straight line if they are unable to see. It is interesting.
My eight year old watched it with me. She wants to try out the experiment herself. So, we are going to do that on a not so muddy day in the near future. I’ll take pictures and video to share with you here.
I would love to see this experiment done with a blind person who was not allowed to use a cane.
I am curious to know if they are more sensitive to their environment which may allow them to walk straight ahead or at least more successfully than a sighted person.
