1. Technical Field
The present disclosure relates to a method for adjusting a font size of a character displayed on a screen.
2. Description of Related Art
Generally, a mobile terminal includes a screen for communicating with a user. A font size of a character displayed on the screen is usually unchangeable. When the font size is too small, the user has to move their eyes close to the screen of the mobile terminal for reading the character clearly, and even then may not be clear for those with poor eyesight.
What is needed, therefore, is a method for adjusting a font size of a character displayed on a screen automatically according to a reading distance between a user and the screen.
Referring to
A plurality of font size numbers F1, F2, F3, . . . , Fn of characters are defined in the character database before using the mobile terminal 10, and F1 is configured to a smallest font size, Fn is configured to a largest font size. The font size number F1 corresponds to a normal reading distance between the eyes of the user and the screen 11 of the mobile terminal 10 detected by the distance detecting device. For example, representing a current reading distance as X, and defining normal reading distance as 20 centimeters (cm), when X is equal to 20 centimeters, the font size F1 will be used.
Referring to
In the above table, 20 centimeters is regarded as the normal reading distance, and the font size number F1 is the default font size. The normal reading distance and the default font size of the character can be set arbitrarily according to the requirements of the user. The intervals of the reading distances in the relationship table can also be set arbitrarily.
