Student thesis: Termpaper


In this project, we have examined the blind, and how they move around in cities. We have especially examined their behavior and such around crosswalks and their respective traffic lights. In this we have found, among other things, that several municipalities turn down the sound system that stems from the traffic lights. They do this because the surrounding residents have complained a lot about the sounds. Of course this isn’t a good thing, as the blind uses these sounds to determine where the crosswalks are, and to determine when they can cross. During the course of the project, we have used different methods to gather the needed information. These methods include both a couple of qualitative semi structured interviews as well as a quantitative questionnaire. We did both of these to insure maximum efficiency to determine the right solution to our problem. We have also carried out some tests on ourselves, so we could try how it was to be blind, just so we could get a better feel for the problem. We have built a prototype of two electrical circuits, which is meant to be placed on both the traffic light and on the blind person. These two circuits are then supposed to react as “proximity chips” so the sounds on the traffic lights go off, when the chips are close. Although we haven’t properly tested them because of various variables such as delays in components and such, we believe that these chips will have an impact, as they fix both the residents and the blind peoples problems, because the sound only will go off, when the chips are in proximity to each other.
