Patent ID: 8538156

Claim:
A character recognition device which recognizes an operation for writing a character performed by a housing including an acceleration sensor that senses at least two axes being moved in a plane, based on a measurement result from the acceleration sensor, the character recognition device comprising: an acquisition unit which acquires the measurement result from the acceleration sensor which is based on the operation for writing the character performed by the housing being moved in the plane, as acceleration data of a component associated with each axis; an identification unit which identifies, with the acceleration data of each component sequentially acquired by the acquisition unit as a series of acceleration data that are temporally continuous from a first stroke to a last stroke of the character including acceleration between strokes, a plurality of feature points that exist in the series of acceleration data for each component; a generation unit which generates feature point data for each component including the plurality of feature points identified by the identification unit, as inputted character data; and a character recognition unit which performs character recognition by collating basic character data, which has been prepared in advance for use in the character recognition, including a plurality of feature points for each component, and the inputted character data generated by the generation unit; wherein the generation unit determines, for each feature point in acceleration data associated with one axis of the two axes, data indicating a correlation with feature points in acceleration data associated with another axis, as a correlating feature with the other axis, and generates feature point data for each component which includes the correlating feature with the other axis as the inputted character data; and wherein the basic character data includes the correlating feature with the other axis as data related to each feature point.
