Abstract
Abstract An interactive graphics system for precisely locating a boundary of a user-selected text field on a digitized form, enabling the user to accurately enter information into the text field. Upon receiving a user-selected coordinate of a point within the selected text field, the graphics system automatically determines the boundary of the text field by searching the neighboring area for particular obstructions based upon a user-provided type indication. Generally, the graphics system includes a means for receiving information pertaining to a selected text field, including the user-selected coordinate and text field type. A text field identifier associated with the indicated text field type determines the boundary of the selected text field. The text field identifier implements one or more boundary locators, each specifically configured to search for particular obstruction and to determine a text field boundary associated with that obstruction.
