CONSTITUTION:A C-character (one part of a ring is disconnected) 1 is displayed on a display as a symbol for the recognition of eye sight. A touch sensor is provided on the display. When first touch to the display is sensed, the zoom-up of the C-character is started. When the second touch is sensed, the zoom of the C-character is stopped and the eye sight of a device user can be recognized according to the size of the C-character when the zoom is stopped. Namely, the user observes what a picture on the display is before the device is used. Then, when the user can judges the picture is the C-character, the user touches the display twice in a short time. When the user can not judge the picture is the C-character, the user touches the display once and the C-character is zoomed up. After that, when the user can decide the picture is the C-character and touches the display again, the zoom-up is stopped. |
