Objective For people with impaired central vision, novel artificial optical devices can provide access to simplified images by projecting them onto retina regions out of the macula, thus allowing them to utilize peripheral vision to perceive information. We investigate perceptual characteristics of peripheral visual field and provide clues for the design of implantable optical artificial vision devices.Methods We propose an experimental environment for investigating perceptual characteristics of peripheral vision, in which pattern stimuli of symbols, numerals, and Chinese characters are applied to the subjects, with variables including the size, the color combination, the eccentricity, and the motion controlled. The relation between perceptual capability and the variables are analyzed using graphical methods.Results The perceptual capability declines as the eccentricity increases, forming two appreciable trends, and it is significantly influenced by color combination and size.Conclusion Variable combinations with considerable perception rate are provided. The results may promisingly act as a reference for the implantation of artificial optical devices in eyes, the development of color symbol codes for special communication, etc.
