Rotational Movement Perception of Spiral Patterns on Dynamic Sphere Surfaces Based on Line Angles

Abstract

The research on motion perception mainly focuses on flat images, and there is lacked research on 3D aspects. This study discussed the rotational dynamic optical illusion movement perception of a sphere through the dimension of the psychology of vision in the domain of basic modeling. The modeling bodies in prior studies mainly focused on cylinders and cones; therefore, the sphere was set as the main research direction of this paper for studying the line angle optimization of spiral patterns on dynamic sphere surfaces. The study provides five different angles of samples, that angles are 5°, 10°, 15°, 20°, and 25°. This study employed the method of adjustment in experimental methods to study the induced movement effect and movement afterimage effect of spheres through dynamic modeling. The findings showed that the sample at the line angle of 5° brought a better dynamic optical illusion movement perception to the subjects when the sphere was in a rotational movement. The results of this study were expected to provide a reference for future researchers and related art design creators.
