Both apparent and real motion are processedby the same visual system.
The perception of real motion is also
complemented by the brain.

Real motion also cannot be perceived
if it is too fast or too slow.

coresponding problem
Our visual system instantly interprets themovement and derives a corresponding
representation.
However, it is not always the case that
representations appear “as drawn” or“as the difference”.

However, the response changes dependingon the conditions under which the stimulus
is presented (time, size, etc... ).
The techniques of animation make use of thesefunctions of the human visual system.

Norman Mclaren
Animation is not the art of drawings that move but the art of movementsthat are drawn. What happens between each frame is much more
important than what exists on each frame … Animation is therefore theart of manipulating the invisible interstices that lie between frames .
