Abstract
A handheld device allowing comprehensive touch input on a small part of a large display screen includes a touch screen, a display, a touch sensor, and a control module. The handheld device enters to a first input mode in response an operation on the touch screen. The control module controls the display to display a first virtual keyboard, an input operation area, and a character input area in the first mode. In response to operations in the input operation area, the display displays a character of the first virtual keyboard in the character input area. An input method is also disclosed.
