I continue to be amazed at how many people with or without mental or physical challenges make their way through busy airports in large cities. This kind of spatial problem solving for finding one's way is known as wayfinding. Even the cues to steer one’s way can be confusing. On occasions when I have asked for directions, I found myself thinking of better ways the information could have been conveyed. Signs, maps, and other graphic or audible methods can be very helpful if they are done to meet needs appropriately.
Wayfinding signs can help people identify objects and find locations. They can be particularly helpful in warning them about dangerous situations and where to locate safety. There are many aids available to assist people with Alzheimer’s. In this video, a person with Alzheimer's explains how signs help him operate more independently in locating his clothes to dress himself.
