Managing real-time handwriting recognition

Abstract

Methods, systems, and computer-readable media related to a technique for providing handwriting input functionality on a user device. A handwriting recognition module is trained to have a repertoire comprising multiple non-overlapping scripts and capable of recognizing tens of thousands of characters using a single handwriting recognition model. The handwriting input module provides real-time, stroke-order and stroke-direction independent handwriting recognition for multi-character handwriting input. In particular, real-time, stroke-order and stroke-direction independent handwriting recognition is provided for multi-character, or sentence level Chinese handwriting recognition. User interfaces for providing the handwriting input functionality are also disclosed.

Description

technical field [0001] This specification relates to providing handwriting input functionality on computing devices, and more particularly to providing real-time, multi-script, stroke order independent handwriting recognition and input functionality on computing devices. Background technique [0002] Handwriting input methods are an important alternative input method for computing devices equipped with touch-sensitive surfaces (eg, touch-sensitive display screens or touchpads). Many users, especially in some Asian or Arabic countries, are used to writing in cursive style and may feel more comfortable writing in normal handwriting than typing on a keyboard. [0003] For some logographic writing systems such as Chinese characters or Japanese Chinese characters (also known as Chinese characters), although there are alternative syllable input methods (such as pinyin or kana) that can be used to enter the characters of the corresponding logographic writing system, but in the user...
