The Human Factors: Human Factors Applies to Everything, Even Political Campaign Signs

Ergonomics of political signs ...

"November is just around the corner, and you know what that means: as you drive, your eyes will be visually accosted by an abnormally large number of small plastic signs on the side of the road. Oh yes, it is the height of election season. Political campaigns invest a significant amount of money in these signs each election year hoping to sway those undecided voters at the last minute, and yet I am always surprised at how much more effective these signs could be if the sign designers were to apply some basic principles of human perception and memory to their designs.

Visibility Matters
The first goal of a political campaign sign is to be seen. Many signs fail at this step, because they cannot be seen at all from a passing car – they blend into their surroundings. Although vision is the most powerful sense, humans are not great at noticing an object with the same primary color as its surroundings, particularly when engaged in another task like driving. The more distinct a color is from its surroundings, the better chances are that it is noticed. Therefore, consider the environment around a sign: most are placed close to the ground. This means it will be surrounded by greens, light blues, and browns. By selecting a color that is as different as possible from these surrounding colors, the sign “pops” from its surroundings, and the chances of it being noticed by a passing car increase. The best sign colors are usually dark, such as navy blue.

Another consideration is the location of the sign. Most of these types of signs are placed low to the ground. As election day approaches, more and more signs are posted, until there are so many they blend together. How can a sign stand out from such visual clutter? One solution would be to place the sign higher than the others, or make the sign a different shape from the others."   (Continued via WRAL)   [Ergonomics Resources]
