Abstract
The present invention provides an improved method for targeting in a computer system. A block of data is identified by analyzing strokes of writing to determine if a current stroke is to be associated with an existing block of data or with a new block of data. Displacement in the X direction and Y direction between a prior stroke and a current stroke is generated and analyzed to determine if a new block of data has been created. After a block of data has been identified, the bounds of the smallest rectangle that contains all of the strokes in the block are determined. The area overlap between the bounded rectangle and every object or field touched by the rectangle is calculated. If a preselected threshold percentage of the bounded rectangle overlaps a single field or object, that field or object is identified as the target. If no one field or object is overlapped by at least the preselected percentage area of the bounded rectangle, bounding rectangles are defined for each character or stroke in the block of data. The amount of overlap of the bounded characters is determined, and the field having the greatest area of overlap is identified as the target field.
