Context and Expectation

A classic example of the importance of context in pattern recognition. Although the central character is the same when viewed inline either vertically or horizontally, its meaning differs depending on contextual cues from its surroundings.


The Road to Clarity

typeface legibility

As young readers we learn to make sense of words by memorizing shapes and vocalizing each individual letter in order, one at a time, until the entire word is formed. As we learn, we become able to recognize entire words at a glance, based on familiarity and context, without the need to work out individual character shapes.

Clearview, the typeface slated to replace Highway Gothic as the standard font for US road signage, takes advantage a driver’s perceptual ability to recognize word shapes, thereby allowing them to read quickly at high speeds and at greater distances than is possible with today’s signs.

Here’s a great NY Times Magazine article (registration required) about the design and testing of Clearview. Additional info and a commercial version of the font is available for purchase at
