A Tibetan input system and method combining handwriting and keys

Abstract

The invention provides a system and method for Tibetan input with combination of hand writing and keys. The system provided by the invention is composed of five parts including a Tibetan track collection module, a Tibetan hand writing basic letter recognition module, an image display module, a key receiving module and a Tibetan letter combined module. The method provided by the invention comprises the steps that (1) a database is established; (2) hand writing Tibetan basic letters are input; (3) the hand wiring Tibetan basic letters are recognized; (4) images of candidate Tibetan basic letters are displayed; (5) Tibetan basic letters are selected; (6) the selected images of the Tibetan basic letters are displayed; (7) unicode codes corresponding to the Tibetan basic letters are stored; (8) Tibetan additional letters are input; (9) unicode codes corresponding to the Tibetan additional letters are stored; and (10) Tibetan syllables are output. According to the invention, the Tibetan syllables could be input efficiently, conveniently, naturally and accurately on a mobile terminal.

Description

technical field [0001] The invention belongs to the technical field of image data processing, and further relates to a Tibetan input system and method combining handwriting and keys in the technical field of character recognition. The invention can be used to input Tibetan syllables on the mobile terminal. Background technique [0002] At present, the Tibetan input method on the mobile terminal generally adopts the Tibetan key input system and the keyboard type Tibetan input method. Due to the relatively large number of Tibetan letters, there are 41 consonant letters and 15 vowel letters in the local Tibetan and Sanskrit Tibetan, which makes the existing Tibetan input method on the mobile terminal too complicated. There are too many keys on the Chinese keyboard, the input method is unnatural, and the input efficiency is low. [0003] Four people including Nima Zhaxi proposed a Tibetan input method in their patent document "Tibetan input method and system" (public number: C...

AI Technical Summary

Problems solved by technology

Although this method can realize the input of Tibetan characters, the shortcomings of this method are: due to the large number of Tibetan letters, some letters have deformation forms, and the letters can be combined up and down. A large number of keys is required, and the input module of this method contains 47 keys, which makes the keyboard input steps of Tibetan on the mobile terminal more complicated and very inconvenient for people to use

Although the input method of this system has solved the problem of too many keys of the mobile terminal input method, the weak point that this input method still exists is: the keyboard layout of this input system is composed of the main keyboard, the first auxiliary keyboard and the second auxiliary keyboard Composition, so that the page needs to be turned and input on the mobile terminal, but the problem that the button input method is too complicated still cannot be avoided

[0005] In summary, although the existing input systems and methods on the mobile terminal can realize the function of Tibetan syllable input, they do not take into account the defects in the input of Tibetan letters in the key input mode, so that the Tibetan syllables of the mobile terminal Input is not convenient enough
