Enhancement of Application Software for Examination of Differential Magnification Methods and Magnification Interface Factors

摘要

The variable visual acuity nature of human vision across fovea and periphery prompted the need to study the differential magnification method as compared with the traditional linear magnification. With differential magnification, outer-area objects were magnified at a level higher than the inner-area objects. An application software was specially developed by the authors previously for the examination of differential linear and traditional linear magnification methods. This paper presents the enhancement of the application software and the addition of other magnification interface factors which worth further investigating. The newly designed differential nonlinear magnification method was featured and comparisons were made with the differential linear and the traditionally linear magnification methods.
