Relations between the visibility of a character and the eye movement in the difference of font types

There are many font types today. These characters are important in order to acquire information and are needed more visible but relations between the shape of the character and visibility are ambiguous. In this paper describes a relation between a shape of number and visibility. We shown subjects the character of different font types and examined eye movements. An eye mark recorder was used for record of eye movements. The recorded result conducted eye movement paths and fixation frequency. In addition, the reaction time to the shown number was calculated. At the last of the experiment, we made the subjects to evaluate the visibility of each font type.
