Optical Illusions

An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality: the information gathered by the eye is processed in the brain to give a perception that does not really match the real source.

Your brain will try to make sense of whatever you see. Sometimes, though, in its sense-making effort, it tricks us into seeing something that is not there: the image below, for instance, is not really moving—it is all in your head.

Why is this important for those in visual communications? Because perception is experienced as reality; people believe what they see. So make sure you show what you intend others to see!
