For humans who are not visually impaired, vision is the most important source of information about the world. Cognitive scientists have demonstrated how human, animal, and computer vision works. Whether natural or created, vision and its interpretation is a data intensive process. In humans and animals interpretation of visual input begins early in the structure of the visual system and continues deep in the brain. Watch the Kiki video below, to see how it takes nearly five minutes to explain a few seconds of visual input and interpretation. Computer vision, too, has progressed rapidly. Facial recognition technology is a recent example. Facial recognition works but there are privacy concerns about its use that will need resolution soon.


The Eye

Sign Clutter

Notice the confusion of typefaces, colors, and sizes. All make reading a sign from a vehicle difficult.

Overglow

Usually, light helps reading. Here, too much light makes reading difficult

Clearview Details

Notice the subtle but important differences that make Clearview easier to read

Comparison

Here, a new Clearview sign replaced the older Highway Gothic one

Research

Here is one way signage research can be conducted safely. Notice that the driver is NOT a participant!

Why is all of this cognitive science?
