The major difference between scanning and tracking is that:
◦ tracking involves looking at all specific features of an object moving through the visual field; scanning relates to looking at specific features of a non-moving object.
◦ tracking involves perception of movement from right to left, whereas scanning involves perception of depth.
◦ tracking involves perceiving vertical movement, whereas scanning involves perceiving horizontal movement.
◦ tracking involves following movement visually, whereas scanning involves looking at all specific features of an object.
