SMOOTHING AND VISUALIZATION OF DIGITAL HANDWRITTEN INPUT USING GPU Russian patent published in 2019 - IPC G06F17/24 G06F3/354 G06F3/41 G06F3/488 G06K9/22 

FIELD: physics.

SUBSTANCE: invention relates to handwriting. First and second handwriting points are received, and the active Bezier approximation is calculated based on them, the third handwriting input point is determined, whether the third handwritten input point with active Bezier approximations is properly matched, if it is determined that the third handwriting point is properly matched, the updated Bézier active approximation, which includes the first, second and third handwriting input points, if it is determined that the third handwriting point is not properly matched, another new Bézier approximating is calculated, which includes a third handwriting input point, but not the first and second handwriting points.

EFFECT: technical result consists in providing input using digital ink input, which looks smoothed during and after input by means of a stroke at considerable zoom levels.
