The Delboeuf illusion is a phenomenon in which the perceived size of an object changes depending on the size of the surrounding shapes. In this optical illusion, typically examined using two concentric circles, a central circle of fixed size is perceived differently based on the size of the surrounding circle.HistoryThe illusion was first described in 1865 by Joseph Delboeuf. In his experiments, the diameters of concentric circles were compared. The results demonstrated that the size of the surr

The zoetrope is a device that creates the optical illusion of moving images. It was invented in 1834 by the British mathematician William George Horner. This device enabled the earliest steps in the creation of moving images and made significant contributions to the development of animation and cinema. The zoetrope operates by exploiting the human eye and brain’s ability to perceive a sequence of still images presented rapidly as continuous motion.Structural Features and Working Principle of the

Visual illusion can be defined as a mismatch between the objective properties of the external world and their subjective representation. In other words, it is the phenomenon in which the visual sense perceives images under certain conditions in ways that differ from their physical reality. This occurs when a stimulus received through the sensory organs is interpreted differently in the mind due to erroneous assumptions or inferences. Illusions are a pervasive reality that manifests in all areas
