Abstract
A handwriting stroke information encoder capable of reducing costs resulting from communication and storage of encoded data by reducing the amount of the encoded data. The handwriting stroke information encoder is provided with a processor which calculates forecast coordinates from sampled coordinates to be encoded and coordinates sampled before the sampling of the sampled coordinates, and an encoder which encodes the differences between the forecast coordinates and sampled coordinates of an actual input. The coordinates are forecast as; e.g., coordinates that are in line with the extension of vector, which are connecting together the previously-sampled coordinates and coordinates sampled prior to the previously-sampled coordinates, and are spaced the magnitude of the vector away from the previously-sampled coordinates.
