Dont' forget that we technically need to make our maps accessible, too. If you don't have time or resources to get a tactile map made for you, you can do what I did for the blind student. I drew out a simple map of our small campus. I then smeared a little of the glue around to fill in the buildings so the map wasn't just lines, but actually allowed a person to feel the whole building as a filled in shape. Then I used a Dymo tape labeller to label buildings.
Some students pick up orientation easily and want to know all they can.
Others don't have that spatial ability and need to memorize routes, but have no concept of how they relate. I think it is a good practice to have a tactile map available and maybe have a guide show new routes each semester, but really, the best orientation is going to come from a specialist. Don't fall into the trap as we did of providing escorts all the time. This doesn't promote indepedence at all. I think that the reason the guides were provided.
