  • Patent number: 10366626
    Abstract: A method for facilitating handwriting practice includes: generating handwriting strokes in response to user input of user-writing strokes; generating an input image that includes the handwriting strokes, and that has a shape similar to a shape of a standard image associated with a standard word character; scaling the input image to generate a scaled image with a size that is the same as a size the standard image; overlapping the standard image and the scaled image; comparing an nth handwriting stroke in the scaled image with an nth standard stroke in a standard order of the standard word character; and when the nth handwriting stroke does not correspond in position to the nth standard stroke, displaying a notification of a stroke order error.
