Method and apparatus for performing handwriting recognition by analysis of stroke start and end points
First Claim
Patent Images
1. A method in a data processing system for performing handwritten character recognition, the method comprising the computer implemented steps of:
- responsive to user input to a pointing device entered through a computer interface, identifying a stroke start event and a stroke end event;
deriving a stroke parameter from the stroke start event and the stroke end event;
transmitting the stroke parameter to a server; and
receiving a candidate character from the server, wherein the candidate character is based on the stroke parameter.

Abstract
A method, computer program product, and a data processing system for collecting handwritten characters and performing handwriting recognition based on parameters calculated from strokes of the handwritten characters. Stroke start and end events are identified and stroke parameters are calculated from coordinates of the stroke start and end events. One or more candidate characters are identified based on the stroke parameters.

9. A computer program product in a computer readable medium for performing handwriting recognition comprising:
-
first instructions for displaying a collection area in a computer interface and adapted to determine a start point and an end point of a stroke input into the collection area, the first instructions, responsive to determination of the start point and the end point, calculating a stroke parameter set describing attributes of the stroke;
a reference character dictionary including a plurality of records each defining a respective reference character; and
second instructions, responsive to a comparison of the stroke parameter set with the plurality of records, for identifying at least one reference character as a candidate character. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A data processing system comprising:
-
a pointing device;
a display;
a memory that contains a set of instructions; and
a processing unit, responsive to execution of the set of instructions, for providing a computer interface that identifies a start point and an end point of a handwritten character stroke input to the pointing device, a first stroke parameter set calculated by the processing unit responsive to identification of the start point and the end point. - View Dependent Claims (17, 18, 19, 20)
