Change Blindness is a phenomenon that occurs when a substantial change has taken place in one's visual field but one fails to notice it. Change blindness experience can be generated when a brief flash comes between two versions of a scene. This flash prevents the change from rising to the level of consciousness unless the person is actively attending to the object. The interesting aspect is that once the change is noticed, it seems so obvious. This program lets users trace out the pattern that they adopt when scanning through a blurred or low-contrast scene. Move the mouse to guide the circle and then click when you've found the change.
