Embodiment Construction

[0057] Many electronic devices have a graphical user interface with a soft keyboard for character entry. On some electronic devices, the user may also be able to install or enable a handwriting input interface that allows the user to enter characters by handwriting on a touch-sensitive display or surface coupled to the device. Conventional handwriting recognition input methods and user interfaces suffer from several problems and disadvantages. For example,

[0058] • Usually, the regular handwriting input function is enabled on a language-by-language or script-by-text basis. Each additional input language requires the installation of a separate handwriting recognition model that occupies a separate storage space and memory. Little synergy can be provided by combining handwriting recognition models for different languages, and mixed language or mixed script handwriting recognition usually takes a long time due to the complex disambiguation process.

[0059]• Furthermore, bec...

Abstract

The invention discloses a method, a system and a computer-readable medium related to the technology for providing handwriting input function on user equipment. The handwriting recognition module is trained to have a vocabulary that includes multiple non-overlapping scripts and is capable of recognizing tens of thousands of characters using a single handwriting recognition model. The handwriting input module provides real-time handwriting recognition independent of stroke order and stroke direction for multi-character handwriting input. Specifically, it provides real-time handwriting recognition independent of stroke order and stroke direction for multi-character or sentence-level Chinese handwriting recognition. A user interface for providing handwriting input functionality is 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...
