 * THE STUDY OF WALKING WITHOUT SIGHT **

The purpose of this study was to find out how much the lack of sight affects how straight a person can walk. Eyes are very important in the body because they give the ability to see, the eye is a circular ball with a small bulge in the front of it and a very important feature in the eye that gives sight is the retina where electrical nerve impulses are created and sent through the optic nerve to the brain, and the brain determines what is being “seen”. Meter sticks were used to measure out 5m, 10m, and 15m and 5 volunteers were blindfolded and walked 5m, 10m, and 15m without sight and the distance they were away from the target at the end of the distance was recorded in cm. The results from this experiment were for 5m, the average was 42cm away from the target, for 10m, the average was 82.2 cm away from the target, and for 15m, the average was 125.4cm away from the target. The cm they were away from the target rose with the higher distances that they had to walk because the longer they walked, the more off course the person is likely to go.
 * ABSTRACT **

An improvement that can be made to this experiment is to make sure that the volunteers have about the same height, therefore making sure that they take about the same length of steps. This would help because the person would be moving the same distance from each step which would make the data more accurate. Another improvement that can be made to this experiment is to make sure that the person that is walking, completely knows that they are supposed to walk the straightest that they can because if they don’t know, they will just walk normally and that can affect the accuracy of the results. A future experiment that could be done from this experiment is doing the same thing, but with no shoes on because they thickness and the type of shoe that is worn could have an impact on how straight the person walks.
