Human Characteristics of Space Perception : Perception of Horopter and Alleys

Abstract

As the human characteristics of space perception, the phenomena of subjectively straight lines such as Helmholtz's horopter, the parallel alley, and the equi-distance alley are well-known in binocular visual space. In this paper, these phenomena and other similar phenomena in tactile space and auditory space are introduced. Mathematical models to explain these phenomena are also introduced, and an example of the application to the virtual system is explained.
