碩士 === 國立高雄應用科技大學 === 工業工程與管理系 === 100 === In this study, we explore the visual perception of Taiwanese people in Kaohsiung area to understand the difference of optical illusions between 2D and 3D “optical illusion graphics”. The samples are divided into two age groups, the young and the mid- to old-aged, and there are males and females in both groups. The questionnaire of geometrical optical illusion graphics is designed to test the subjects, and the results of the statistical analysis are as follows: 1. For both 2D and 3D graphics, the degree of optical illusion of the mid- to old-aged is higher than that of the young, and the degree of optical illusion of the female is higher than that of the male, but the differences between the gender and age factors are not significant. 2. The degree of optical illusion in 2D graphics is significantly higher than 3D graphics with 95% confidence level, but there is no significant difference between the gender and age factors. 3. Different viewing orders for 2D and 3 D graphics make no significant differences in the degree of optical illusion. 4. The perceptions of 5 kinds of optical illusion graphics in 2D and 3D are similar, and the degree of optical illusion of concentric circle graphics is the lowest. 5. The average degrees of optical illusion among circle, line and curve graphics are significantly different in both 2D and 3D.
