See View from the Window at Le Gras 1832 Joseph Plateau Belgium and Simon von Stampfer Vienna introduced simultaneously a scientific demonstration device that creates an optical illusion of movement by mounting drawings on the face of a slotted, spinning disk. Plateau s version was variously known as the Phenakistoscope , Phenakistiscope , Fenakisticope or Fantascope , while Stampfer s version became known as the Stroboscope . The device, originally developed to demonstrate persistence of vision , was soon marketed as a novelty toy. 1834 The Zoetrope is invented. The device was a hollow drum with a strip of pictures around its inner surface. When the drum was spun and the pictures viewed through slots on the side of the drum, the pictures appeared to move. The device was first marketed only in the second half of the 1860s when several patents were taken. It was known as Zoetrope , Zootrope , Wheel of Life , etc. 1870s French inventor Charles mile Reynaud improved on the Zoetrope idea by placing mirrors at the center of the drum. He called his invention the Praxinoscope . Reynaud developed other versions of the Praxinoscope too, including a Praxinoscope Theatre, where the device was enclosed in a viewing box, and the Projecting Praxinoscope. Eventually he created the Th tre Optique , a large machine based on the Praxinoscope, but able to project longer animated strips. In the USA, the McLoughlin Bros from New Year released in 1879 a simplified and unauthorized copy of Reynaud s invention under the name Whirligig of Life . 1878 Railroad tycoon Leland Stanford hired British photographer Eadweard Muybridge to settle a bet on whether a galloping horse ever had all four of its feet off the ground.

In 1961, he was awarded the Nobel Prize in Physiology or Medicine for his research on the function of the cochlea in the mammalian hearing organ. Research B k sy developed a method for dissecting the inner ear of human cadaver s while leaving the cochlea partly intact. By using stroboscope strobe photography and silver flakes as a marker, he was able to observe that the basilar membrane moves like a surface wave when stimulated by sound . Because of the structure of the cochlea and the basilar membrane, different frequency frequencies of sound cause the maximum amplitudes of the waves to occur at different places on the basilar membrane along the coil of the cochlea . ref name Goldstein Goldstein, B. 2001. Sensation and Perception, 6th ed. London Wadsworth. ref He concluded that his observations showed how different sound wave frequencies are locally dispersed before exciting different nerve fiber s that lead from the cochlea to the brain. He theorized that the placement of each sensory cell hair cell along the coil of the cochlea corresponds to a specific frequency of sound the so called tonotopy .

Unreferenced date March 2007 Motion graphics are graphics that use video footage and or animation technology to create the illusion of Motion physics motion or rotation, graphics are usually combined with Sound recording and reproduction audio for use in multimedia projects. Motion graphics are usually displayed via electronic media technology, but may be displayed via manual powered technology e.g. thaumatrope , phenakistoscope , stroboscope , zoetrope , praxinoscope , flip book as well. The term is useful for distinguishing still graphics from graphics with a transforming appearance over time without over specifying the form. File Motion Graphics Explained.ogv thumb Visual description of Motion Graphics Motion graphics versus film Empty section date June 2011 Scope of the term Motion graphics extend beyond the most commonly used methods of frame by frame footage and animation. Computers are capable of calculating and randomizing changes in imagery to create the illusion of motion and transformation. Computer animation s can use less information space computer memory by automatically tweening , a process of Rendering computer graphics render ing the key changes of an image at a specified or calculated time. These key poses or frames are commonly referred to as keyframes. Adobe Flash uses computer animation tweening as well as frame by frame animation and video. History of the term Since there is no universally accepted definition of motion graphics, the official beginning of the art form is disputed. There have been presentations that could be classified as motion graphics as early as the 1800s. Perhaps one of the first uses of the term motion graphics was by animator John Whitney animator John Whitney , who in 1960 founded a company called Motion Graphics Inc. Saul Bass is probably the most significant pioneer in motion graphic design , and his work marks the true beginning of what is now commonly referred to as motion graphics.
