Virtual keyboard design and input method for touch screen device

Abstract

Provided is a virtual keyboard design and an input method for a touch screen device. The layout of the virtual keyboard is arranged to be provided with four rows and seven columns. The virtual keyboard comprises 26 letters and two punctuation marks. The first row must comprise the letters u, i and v, wherein the letter v represents the vowel u. The letters u and i must be adjacent to each other. The second row must comprise the letters a, o, e and r, wherein the letter a is adjacent to the letter o and located on the left side of the letter o. The letter e is adjacent to the letter r and located on the left side of the letter r. The second row must comprise the letters u and i. The letters u and i share same virtual buttons with any other two consonants of the second row respectively, and thus vowel and consonant sharing buttons are formed. The letters z, c, s, b, d, f, g, h, j, k, l, m, n, p, q, t, w, x and y, sixteen consonants in total, can be randomly distributed in any positions from the first row to the fourth row. All of the short consonants and the short vowels are acquired by clicking and all of long consonants and long vowels are acquired by sliding. According to the method, the quick and convenient Chinese character pinyin input can be achieved on any touch screen device. The virtual keyboard design and the input method have the advantages that the learning is easy, the input efficiency is high and the misoperation rate is low.

Description

technical field [0001] The invention relates to a Chinese character input method, in particular to a virtual keyboard design and input method for a touch screen device. Background technique [0002] The Pinyin input method is the most commonly used Chinese character input method. The main reason is that the Pinyin input method is easy to learn and use, and it can be input without memorizing the radicals. The disadvantage is that the repetition rate is relatively high and the number of operations more. [0003] With the emergence of touch-screen devices such as smartphones and tablets, physical keyboards are gradually being replaced by virtual keyboards, and many touch-screen devices no longer provide users with physical keyboards. The traditional pinyin input method based on the physical keyboard has to be migrated to the virtual keyboard. However, under the keyboard layout and input rules of the traditional pinyin input method, the virtual keyboard is not only difficult to...

AI Technical Summary

Problems solved by technology

The traditional pinyin input method based on the physical keyboard has to be migrated to the virtual keyboard. However, under the keyboard layout and input rules of the traditional pinyin input method, the virtual keyboard is not only difficult to take advantage of its rich operation methods, but also makes it have no sense of positioning. Especially because the contact area of ​​the key is relatively small, the disadvantages such as high misoperation rate are more prominent
