Abstract
A pen input device and method for a pen computing system. This device includes a touch screen panel mounted on a display screen, an electronic device interfaced with the panel, and a pen for inputting data. When a user handwrites a character, or a symbol on the screen panel, a stream of points is displayed on the touch screen panel to express the handwritten character equivalent to a character handwritten on a paper using a pen. When a user draws a boundary line having a specific shape on the touch screen panel using a pen, the pen input device forms a new entry field inside the boundary line. The user can enter a handwritten character or number in the entry field. In response to this entry, the pen input device converts the entered handwritten character or symbol to a computer text or instruction word. The pen input device also enables the user to determine the attributes and size of the generated entry field.
