Color can be compelling or it can be confusing background noise and visual clutter. When used as a coding device, four colors are the understandable limit for the average user. By clearly defining color's function, what it means and how much color to use, the design team can boost the impact of the system. In our increasingly multilingual society, the use of dual-language signage systems is often mandatory. Critical as these systems are they can be difficult to administer.
Consistency is key to effective use of maps.
By presenting the user with one consistent format from application to application, even when maps of varying scales and detail are required, and maintaining a consistent orientation, mapping reinforces recognition and orients the viewer. A successful wayfinding strategy can be generated by a core group of two or three key decision-makers, or may require broad groups of specialists. The user requirements and preferences are solicited in a number of ways, among them focus groups and surveys. The facility staff continues to be important even after the wayfinding plan has been implemented. Inevitably, building personnel will be solicited to help users find their destinations.
