  • Patent number: 5034989
    Abstract: An apparatus and a method for identifying handwritten characters is provided, each of the characters being a member of a set and being formed from a number of predetermined primitives. The apparatus includes an input device receiving successively each primitive forming a character. The input device generates input signals for each primitive forming the handwritten character. The input signals are conveyed to a processor. The processor examines the input signals and attempts to identify each of the primitives used to form the handwritten character. A primitive code is generated for each identified primitive and an unidentified primitive code is generated for each unidentified primitive. The primitive and unidentified primitive codes are combined to form an input character code. A memory is provided and stores a character code and an international output code for each of the characters in the set of characters.
