The effect of apparent size on geometric plane forms by difference of layout angle and hue

Nowadays, we have seen many composition elements such as a letter and a picture to appear in visual com-munication media (TV, World Wide Web, newspaper etc.). As it has been reported, a plane figure has a different psychological influence in dependence on its layout angle in the field of vision. And, in the composition elements of these media, it is thought that symbol and logo mark give the impression that they are near to a plane geo-metric figure to viewer. It has been reported that visual balance is influenced by form, color and texture of components, and layout angle in a field of vision. In this paper, we study how changing the layout angle and hue influences the apparent sizes of plane geometrical figures (triangle, square). In experiment, we used the method of adjustment on LCD. Results revealed that the layout angle of square was significant and the differ-ence of hue was not significant.
