Abstract

This disclosure describes systems, methods, and devices for reflow of digitally entered handwritten characters into a device. A method may include receiving handwritten strokes digitally entered into a text container presented using a device; generating groups of the handwritten strokes into text lines and words along the text lines; determining, using a baseline estimation algorithm, a respective baseline for each of the text lines; identifying, for each respective baseline, a lowest x-coordinate of the handwritten strokes; determining, for each of the words, a distance between a respective word on a respective baseline and a consecutive word on the respective baseline; determining, based on a width of the text container, the respective baselines, and the distance, a placement of each of the words in the text container; and causing presentation, using the device, of the words in the text container based on the placement.

Abstract

This disclosure describes systems, methods, and devices for analyzing and providing suggestions for handwritten math characters entered on a device. A method may include receiving first handwritten strokes digitally entered on the device by a user; inputting the first handwritten strokes into a machine learning model; classifying, by the machine learning model, the first handwritten strokes as first mathematical characters; causing the device to present, based on the classifying, a selectable indication of the first handwritten strokes; receiving a first user selection of the selectable indication; causing the device to present, based on the first user selection, one or more selectable suggestions for second mathematical characters to follow the first mathematical characters; receiving a second user selection of a first suggestion of the one or more selectable suggestions; causing the device to present, based on the second user selection, synthesized second handwritten strokes representing the second mathematical characters.
