A method for the angle-independent recognition of handwritten objects including: a) receiving a handwritten stroke; b) normalizing the stroke; c) matching the normalized stroke against a stroke database to obtain at least one character part interpretation; and d) recognizing a handwritten object using one or more of the character part interpretations. Preferably, the step of normalizing the stroke includes the step of normalizing an angle of the stroke by first determining a stroke angle and then rotating the stroke by the stroke angle until the stroke is at a normalized position. An apparatus for the angle independent recognition of handwritten objects includes: a) a central processing unit (CPU); b) a pointer mechanism coupled to the CPU for providing a handwritten stroke to the CPU; c) a mechanism for normalizing the strokes provided by the pointer mechanism; d) a mechanism for matching the normalized strokes against a stroke database to obtain a number of character part interpretations; and e) a mechanism for recognizing a handwritten object using the character part interpretations. Preferably, the mechanism for normalizing the strokes includes a mechanism for detecting stroke angles of the strokes, and a mechanism for rotating the strokes by the stroke angles to create normalized strokes. The mechanism for recognizing the handwritten object preferably includes a controller, a number of recognition domains coupled to the controller, and an arbiter coupled to the controller for resolving multiple interpretations of the object.
