Effect to apparent size by difference of layout angle on the plane figures

In visual communication media, a symbol-logo mark often is presented to a viewer as a plane figure. It has been reported a plane figure varies in it’s the psychological influence by layout angle in a field of vision, and the geometric relations of the figure are different from objective relations. By Kim et al. in the previous study, the type of form may be the same area tends to occur a difference in the size of the visible indicated. Also, there may appear sizes are different and changing the arrangement angle of the figure was suggested. Also, in previous studies of the Fukuda et al. and Kinoshita et al., using the shape of the arrangement angle of 0 ° to the reference stimulus, investi-gated the influence of the arrangement angle of the plane figure the appearance of the size of the case of changing stepwise. In this study, with respect to the circle, the difference between the plane figures and their placement angle with form difference of the same area has on the size of visible impact, and comparison of the size of the visible between each figure and an object that is performed to examine the previous studies of Kim et al. And, In this ex-periment, we found that as the size of inside angle is small when the appearance size of the plane figure is larger.
