One way of changing the direction perceived is to use averted vision and mentally look for an arm going behind instead of in front, then carefully move the eyes back. Some may perceive a change in direction more easily by narrowing visual focus to a specific region of the image, such as the spinning foot or the shadow below the dancer and ...
It consists of a rapid, resetting saccade in the opposite direction of the slow nystagmus (i.e., opposite to the stimulus motion). The purpose of the fast nystagmus is to keep the eye centered in the orbit, while the purpose of the slow nystagmus is to stabilize the moving visual scene on the retina.
At a certain speed the sets of spokes appear to slow and rotate in opposite directions. The wagon-wheel effect (alternatively called stagecoach-wheel effect ) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation.
This makes a vehicle stable at high speed but requires larger steering inputs near the limits of adhesion, especially on low-grip surfaces. Skilled drivers are able to use a maneuver similar to the Scandinavian flick, though with less steering input and control the possible slide by using opposite lock. Since the 2010s, several models of ...
A pointing stick can be used by pushing with the fingers in the general direction the user wants the pointer to move. The velocity of the pointer depends on the applied force so increasing pressure causes faster movement. The relation between pressure and pointer speed can be adjusted, just as mouse speed is adjusted.
Two images that exhibit peripheral drift illusion. The different pattern of light and dark causes the two circles to appear to rotate in opposite directions. The peripheral drift illusion (PDI) refers to a motion illusion generated by the presentation of a sawtooth luminance grating in the visual periphery.

For example, if two forces are acting upon an object in opposite directions, and one force is greater than the other, the forces can be replaced with a single force that is the difference of the greater and smaller force. That force is the net force. [1] When forces act upon an object, they change its acceleration.
