Lenticular printing is a technology in which lenticular lenses (a technology also used for 3D displays) are used to produce printed images with an illusion of depth, or the ability to change or move as they are viewed from different angles.
Billboards and other electronic signs use apparent motion to simulate moving text by flashing lights on and off as if the text is moving.. The term illusory motion, or motion illusion or apparent motion, refers to any optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position.

With the picture so close to their eyes, most people cannot focus on the picture. The brain may give up trying to move eye muscles in order to get a clear picture. If one slowly pulls back the picture away from the face, while refraining from focusing or rotating eyes, at some point the brain will lock onto a pair of patterns when the distance ...
The Motograph Moving Picture Book was published in London at the start of 1898 by Bliss, Sands & Co. [4] It came with a "transparency" with black stripes to add the illusion of motion to the pictures in the book (13 in the original black and white edition and 23 in the later color edition). The illustrations were credited to "F.J. Vernay ...
When a large part of the visual field moves, viewers feel like they have moved and that the world is stationary. [4] For example, when one is in a train at a station, and a nearby train moves, one can have the illusion that one's own train has moved in the opposite direction.
An 1857 textbook on physics mentioned an early cylindrical stroboscopic installation with moving images that was 18 feet (5.5 meters) in diameter and had been exhibited in Frankfurt. A "Great Zoetrope; or: Wheel of Life", 50 feet (15 meters) in circumference, with "life-size figures", was installed in the Concert Hall of the Crystal Palace in ...
Belgium's Henri Starc began imparting dramatic film form to still images in 1936, and his lyric World of Paul Delvaux (1947) is an acknowledged classic. Paul Haesaerts made Rubens in 1948. Americans Paul Falkenberg and Lewis Jacobs made Lincoln Speaks at Gettysburg entirely out of nineteenth-century engravings, 1950.
The ability of a subject to detect coherent motion is commonly tested using motion coherence discrimination tasks. For these tasks, dynamic random-dot patterns (also called random dot kinematograms) are used that consist in 'signal' dots moving in one direction and 'noise' dots moving in random directions. The sensitivity to motion coherence is ...
