DCFirst Claim
1. A graphical user interface for use in a handheld portable data terminal including a display screen and touch screen for sensing location of user contact, the graphical user interface comprising:
- a display sequence displaying multiple virtual regions on the display screen, wherein each virtual region corresponds to an event identifier; and
an event handler for identifying one of the virtual regions that corresponds to the location of user contact sensed by the touch screen, determining a specific event identifier corresponding to the identified virtual region, and processing a predetermined sequence for the specific event identifier;
wherein said multiple virtual regions include a menu screen and a graphing screen, and wherein each selection from said menu screen corresponds to a virtual region and an associated processing sequence.

Abstract
A graphical user interface for use in a handheld portable data terminal including a display screen and touch screen for sensing location of user contact. The graphical user interface includes a display sequence that displays multiple virtual regions on the display screen, wherein each virtual region corresponds to an event identifier. An event handler identifies one of the virtual regions that corresponds to the location of user contact sensed by the touch screen, determines a specific event identifier corresponding to the identified virtual region, and processes a predetermined sequence for the specific event identifier. The multiple virtual regions displayed on the display screen by the display routine preferably includes one of a virtual keypad for entering symbols associated with keys of the keypad, at least one scroll bar, at least one rolling key, multiple icons, a menu screen and a graphing screen. The predefined processing sequence associated with a given virtual region of the display screen is initiated by the user by contacting the associated virtual region. The predefined processing sequences may involve one of data entry operations, data communication operations, and code scan operations. The graphical user interface may also include a text input mechanism that enables the user to enter at least a portion of a desired text data, that automatically searches data stored in memory to retrieve text data closest to the portion of desired text data, and displays the retrieved text data on the display screen.
