This paper indicates that the induction field in vision can predict regibility of character with various resolusion. Recently, it is popular to read electric document on the display device. So, character regibility on display with various resolusion has been focused on as a good display condition. However, there is not enough basic evaluating between character regibility and resolusion. Many previous research activities only suggest relationship between regibility and resolusion. This paper first confirm the relationship by psychological experiment. Then, to explain the experimental result, complexity of induction field corrected by stroke width of character was examined. It is indicated that the corrected complexity using induction field can evaluate regibility of character with various resolusion.
