Visual pop-out is what it sounds like: visuals that pop out at you. Generally, effective pop out methods are hue, luminescence, shape/form, and contrast. This doesn’t work in every situation, though. The brain processes visual info in a set of stages, with separate pathways for high level learning. Movement, color differences, shape/form are thus all processed independently. In practical application, pop-out seems only to work if users know what they are looking for.
