ABSTRACT:
A portable information terminal adopting a soft keyboard includes screen display device for receiving screen data relating to the soft keyboard and displaying the soft keyboard on the display screen. The soft keyboard includes an information key region where the information keys of a predetermined number are arranged in two lines or less, and a scroll key region where one or more scroll direction keys are displayed for scrolling the information keys to select the information keys displayed on the information key region. A method for inputting information using the soft keyboard includes the steps of displaying the soft keyboard on a display screen wherein the soft keyboard includes an information key region where the information keys of a predetermined number are arranged in two lines or less, and a scroll key region where one or more scroll direction keys are displayed for scrolling the information key regions to select the information keys displayed on the information key, inputting an intended key using a pen, and determinating the input key, wherein, if the input key is the information key, a code corresponding to the information key is generated and, if the input key is the scroll key, the information key region is scrolled. Accordingly, the area of the soft keyboard occupying the screen is reduced, to improve the convenience of data input operations.
