Design UI for Recognition More than for Reading (Ryan Nance)

James Montalbano, a typographic designer, knows that legible is good, but recognizable is better. He worked on the Clearview font which has become an official alternate for Federal Highway signs. It is a high pressure reading situation to be sure. The 500 miliseconds to 1 sec it can take to read a highway sign at 70 mph can translate into up to 30 meters. Most drivers, rather than risking such a relatively huge amount of time, don’t ‘read’ signs as much as glance at them. And in recognition speed and distance terms, mixing letter case can contribute to half the time needed and twice the distance. (medium.com)
