Motion perception is the process of inferring the speed and direction of elements in a scene based on visual, vestibular and proprioceptive inputs. Although this process appears straightforward to most observers, it has proven to be a difficult problem from a computational perspective, and difficult to explain in terms of neural processing. Motion perception is studied by many disciplines, including psychology (i.e. visual perception), neurology, neurophysiology, engineering, and computer science.

Werner E. ReichardtWerner E. ReichardtWerner E. Reichardt (30 January 1924 – 18 September 1992) was a German physicist and biologist who helped to establish the field of biological cybernetics. He co-founded the Max Planck Institute for Biological Cybernetics, and the Journal of Biological Cybernetics.LifeAs a young student, Werner Reichardt was a pupil in the laboratory of , a pioneer of ultra-shortwave communication.Visual cortexVisual cortexIn mammals, the visual cortex of the brain is the area of the cerebral cortex that processes visual information. The visual cortex is located in the occipital lobe, located at the rear of the head. Sensory input originating from the eyes travels through the lateral geniculate nucleus in the thalamus and then reaches the visual cortex.AkinetopsiaAkinetopsia (from Greekakinesia 'absence of movement' and opsis 'seeing'), also known as cerebral akinetopsia or motion blindness, is an extremely rare neuropsychological disorder, having only been documented in a handful of medical cases, in which a patient cannot perceive motion in their visual field, despite being able to see stationary objects without issue.Visual perceptionVisual perceptionVisual perception is the ability to detect light and use it to form an image of the surrounding environment. Photodetection without image formation is classified as light sensing. In most vertebrates, visual perception can be enabled by photopic vision (daytime vision) or scotopic vision (night vision), with most vertebrates having both. Visual perception detects light (photons) in the visible spectrum reflected by objects in the environment or emitted by light sources.Cerebral cortexCerebral cortexThe cerebral cortex, also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. It is the largest site of neural integration in the central nervous system, and plays a key role in attention, perception, awareness, thought, memory, language, and consciousness. The six-layered neocortex makes up approximately 90% of the cortex, with the allocortex making up the remainder.Bernhard HassensteinBernhard HassensteinBernhard Hassenstein (31 May 1922 – 16 April 2016) was a German biologist and psychobiologist.Computer scienceComputer scienceStudy of computationFundamental areas of computer scienceProgramming language theoryComputer architectureArtificial intelligenceComputational complexity theoryComputer science is the study of computation, information, and automation, together with their associated phenomena.Vestibular systemVestibular systemThe vestibular system, in vertebrates, is a sensory system that creates the sense of balance and spatial orientation for the function of coordinating movement with balance. Together with the cochlea, a part of the auditory system, it constitutes the labyrinth of the inner ear in most mammals.EngineeringEngineeringEngineering is the practice of systematically applying natural science and mathematics to design and improve systems, devices, or processes that solve problems under constraints. It is typically motivated by satisfying human needs, resulting in creations such as bridges, engines, smartphones, pacemakers, the internet, spacecraft, and washing machines.PsychologyPsychologyPsychology is the scientific study of the mind and behavior. Its subject matter includes the behavior of humans and nonhumans, both conscious and unconscious phenomena, and mental processes such as thoughts, feelings, and motives. Psychology is an academic discipline of broad scope, crossing the boundaries between the natural and social sciences. A professional practitioner or researcher involved in the discipline is called a psychologist.NeurophysiologyNeurophysiologyStudy of neural function Neurophysiology is a branch of physiology and neuroscience concerned with the functions of the nervous system and their mechanisms. The term neurophysiology originates from the Greek word νεῦρον ("nerve") and physiology (which is, in turn, derived from the Greek φύσις, meaning "nature", and -λογία, meaning "knowledge").NeurologyNeurologyNeurology (from Greek: , "string, nerve" and the suffix , "study of") is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the nervous system, which comprises the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system, using various techniques of neurotherapy.Nervous systemNervous systemIn biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensoryinformation by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. Nervous tissue first arose in wormlike organisms about 550 to 600 million years ago.texturetextureRelated word or term.
