Abstract
(EN)

PURPOSE: A character input device using a touch pad and an inputting method thereof are provided to enable a user to input various characters by using 5 areas only, with a touch pad including the 5 areas which are arrayed in square type and from which different signals are generated.

CONSTITUTION: A character input device(20) using a touch panel includes a touch pad(22) which consists of 5 discriminated areas. The touch pad(22) is connected to a touch panel controller(24) for converting a resistance value, a pressure value, or an ultrasonic intensity signal generated by being touched, into a digital value suited for processing. The controller(24) executes a touch panel driving program, and provides signals generated when the touch panel is touched, to a main processor(26) as 5 discriminated area input signals. A memory device(25) stores a character recognition program(200) and a lookup table(300). A display(28) displays characters recognized by the main processor(26) whenever the touch panel(22) is touched.
