[Using graphics in Wayfinding]

The purpose of using graphics is to communicate information or ideas. Successful graphic use combines the context with the image, to bring about clearer, more precise understanding and feeling.

In wayfinding, the graphics must be created for the context of movement. They need to be easily understood and readable from a distance. They need to help people understand their surroundings, not confuse them. Good wayfinding is focused on getting people from point A to point B.

Now let's go back and look at basic Gestalt theory. We want to accomplish coherency through visual means. In Gestalt theory, repetition produces understanding and contrast produces interest. If you want to help people understand they are on the right path, repeat a graphic. If you want to signal a change of direction or node, use a contrasting graphic.
