Webthe psycho-visual redundancy of display devices can be used to generatemultiple visual percepts for diﬀerentviewers, with and without viewing devices. Second, the redundancy can be used for data transmission to computing devices without sacriﬁcing the visual quality, which is in fact a kind of visible light com-munication (VLC). WebPsycho-visual redundancy This type is due to the limitations of human eye sensitivity to visual information. It arises because the eye uses a subjective form of evaluation, characterized by its vast power for perceiving the overall image structure, but with the corresponding loss of being able to perceive each detail (pixel) separately.
