<p>An acquiring section acquires coordinate data about an inputted stroke in order of time series. A creating section creates a real stroke which is the stroke from a pen-down to a pen-up and creates a virtual stroke virtually connecting the coordinate data about the end point of the real stroke and the coordinate data about the start point of the next real stroke with a line segment. An extracting section extracts feature vectors of the real stroke for each of the divisions defined by dividing the region where the stroke exists and obtains a first feature vector composed of the extracted feature vectors. The extracting section furthermore extracts feature vectors of the virtual stroke for each of the divisions and obtains a second feature vector composed of the extracted feature vectors. A recognizing section recognizes the stroke by using the distance between the first feature vector and the vector corresponding to the real stroke out of the vectors corresponding to the identification code and the distance between the second feature vector and the vector corresponding to the virtual stroke out of the vectors corresponding to the identification code.</p> |
