Hand-written input device and method for complete mixing input

Abstract

The invention provides a handwriting input device used for total mixed input as well as a method thereof. The device comprises: an interactive unit which is used for receiving character writing input by a user by hand, and executing the interaction with the user according to an interactive mode; an operation processing unit which is used for receiving character writing from the interactive unit, identifying the character writing for obtaining a group of candidate words, and confirming the interactive mode to be adopted according to the identified candidate words; and a storage unit for storing the character writing input by the user by hand and received by the interactive unit as well as a feature library of total mixed characters, wherein, if the operation processing unit recognizes thatthe preferred candidate word is a special candidate word, the rest candidate words are any words of Chinese characters, digits, English letters and punctuations, and a logic arithmetic unit notifies the message which confirms the interaction with the user by a letter and phonetic alphabet mixed mode to the interactive unit.

Description

technical field [0001] The present invention relates to a handwriting input device and method, in particular to a handwriting input device and method for full mixed input. Background technique [0002] At present, in mobile terminals such as PDAs, PPCs, and smart phones, portable terminals, and micro-terminals, due to the limitations of their display interfaces and keyboards, text input is also subject to corresponding restrictions. [0003] The most commonly used method is to complete the input of characters by buttons or virtual button combinations, but in Chinese input, the input efficiency is not high due to the high repetition rate. [0004] Handwriting input is another commonly used input method. Handwriting input utilizes the font dot trace information input by the user to recognize and convert it into a series of candidate characters for the user to choose. Common handwriting input methods can already support English input, Chinese input and so on. [0005] In ord...

AI Technical Summary

Problems solved by technology

If the user enters these three English characters, after the handwriting recognition engine recognizes the characters, it will not be able to determine whether the user is inputting English characters or the pinyin of Chinese characters, so it will inevitably cause input ambiguity

In this case, whether it is from the context or the use of statistical methods, it is impossible to accurately judge the user's input purpose
