Abstract
A method for magnifying a screen content executed by an input device is disclosed. The method is suitable for magnifying a display content of a computer device and includes that the input device receives an informed command from the computer device. The informed command indicates whether the operation system of the computer device supports a system magnifier. If the operation system supports the system magnifier, the input device outputs a first magnification command to the computer device according to pressing of a function key. The computer device initializes the system magnifier of the operation system and magnifies the screen content according to the first magnification command. If the operation system doesn'"'"'t support the system magnifier, the input device outputs a second magnification command provided by the input device to the computer device, so that the second magnification command magnifies the screen content according to the second magnification command.
