Pen input method and device for pen computing system
First Claim
1. A pen input device comprising:
- a touch screen panel for receiving a pen input from a user and displaying input data corresponding to the received pen input;
an entry field generating portion for generating at least one displayed entry field substantially surrounded by a boundary line when the user draws the boundary line for forming an entry frame;
a controller for resizing the entry field to be suitable for the input data'"'"'s size whenever input data is input to the generated entry field, wherein resizing the entry field includes modifying at least one of a displayed length and a displayed width of the entry field; and
a memory unit for storing recognition information related to the entry field and the input data.

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.
