Wayfinding: The subtle ways you are guided to your destination

If you've lived in a community for a few years, you get to know your way around pretty well. If one road is blocked, you know in your mind how to work around it.

But if you're visiting a different community, especially one in another country, you need signs and other cues to find your destination. Even the shopping lot of a major mall or the halls of a large hospital can leave you hopefully lost.

Enter the world of wayfinders -- people who help you get where your going without having to interrupt employees or become frustrated with the environment you're in.

There's a science to it and today we'll tell you all about it.
