Outline of Final Research Achievements

Introduction of projectors and enlargement of screens in school education is progressing. When teaching material is projected on a screen at an education site, students sitting in the front row see blurred and difficult to read characters, and students sitting in the back row see collapsed characters that cannot be read. Therefore, we studied how to make it possible to evaluate the readability of the character display with viewing distance. We focused on illusion, visual acuity, visual distance, resolution of the display device and conducted an experiment. As a result, the relevance of visual acuity, visual distance, resolution of the display device was suggested. It was also revealed that it is possible to distinguish the gap of the Landolt ring, which is a visual target even at low resolution, and that the number of pixels beyond the Landolt ring is necessary for character reading.
