Abstract: The subject technology provides for stroke based control of handwriting input. The disclosed stroke based control facilitates selection, copy, paste, search, data detection and other operations for handwritten electronic text. The selection of text represented by handwritten strokes can be performed without drawing a lasso or other loop around the desired text, by using known boundaries of words and phrases in stroke space. Selection of text in this manner allows copy and/or paste of recognized words or phrases, of images of the words or phrases, and/or of the strokes themselves. Boundaries, in stroke space, of actionable data represented by the strokes can also allow action options to be provided when a user interacts with strokes within the boundary.

Abstract: The subject technology provides for receiving a new input stroke. The subject technology determines whether the new input stroke is associated with an existing line group based on a writing direction estimate of the existing line group. The subject technology merges the new input stroke with the existing line group in response to determining that the new input stroke is associated with the existing line group. The subject technology determines a local orientation of the existing line group including the new input stroke based on an estimate of a direction of writing and a scale of each stroke. The subject technology normalizes the existing line group including the new input stroke using the determined location orientation.

Abstract: An example process for recognizing handwritten input includes obtaining input data representing handwritten input, where the handwritten input is associated with a first dimension and a second dimension relative to the handwritten input; sampling the input data to obtain a plurality of coordinates representing the handwritten input; determining, based on the plurality of coordinates, a sequence of vectors representing a respective plurality of portions of the handwritten input, where: each portion of the respective plurality of portions is associated with a respective height and width corresponding respectively to the first and second dimensions, the respective height being greater than the respective width; and consecutive vectors of the sequence of vectors represent respective consecutive portions of the handwritten input; generating, using a handwriting recognition model, based on the sequence of vectors, one or more characters for the handwritten input; and causing the one or more characters to be displayed.
