Animation plays important roles in design education. In this paper, the visual communication study on one’s perception of motion for animation on a computer screen is given. This study includes experiments, questionnaires and statistical analyses. Initially, samples of dynamic images are displayed on a computer screen. These dynamic images are composed of geometrical elements including circles, triangles and squares. The shape of image elements, gap distance between adjacent elements, moving speed, moving direction, and subjects’ educational background are independent variables. Experimental subjects are asked to observe the dynamic images and then answer questionnaires about perception of motion. Finally, investigated data are analyzed by the analysis of variance (ANOVA) and the independent-sample T-test. Our results show that neither the moving direction nor the moving speed of a dynamic image are important factors in our experiments. Whereas the gap distance, element shape of a dynamic image and subjects’ educational background are important factors. This study can be applied to the design education.
