Virtual keyboard based on touch screen equipment and input method of virtual keyboard

Abstract

The invention relates to the technical field of input methods, in particular to a virtual keyboard based on touch screen equipment and an input method of the virtual keyboard. 26 English alphabet keys are displayed on the virtual keyboard, the alphabet keys a, e, i, o and u are continuously arranged, and the remaining alphabet keys b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, w, x, y and z are arranged behind the alphabet keys a, e, i, o and u in the sequence of the standard 26 English alphabet. According to the input method, Chinese character Pinyin is input by sufficiently utilizing gesture actions including clicking, sliding, dragging and the like on a touch screen, and particularly, input of vowels of a multi-vowel alphabet combination and nasal vowels is facilitated. The virtual keyboard has the outstanding advantages that the key position layout design of the virtual keyboard is simple and easy to remember, the input rule definition is not complicated, and technical realization and market popularization are facilitated. The virtual keyboard can be applied to information input of the touch screen equipment.

Description

technical field [0001] The invention relates to the technical field of input methods, in particular to a virtual keyboard based on a touch screen device and an input method thereof. Background technique [0002] At present, on touch screen devices, such as smart phones, most of the common virtual keyboards are laid out in the manner of QWERTY full keyboard or digital nine-square grid. Both of these two virtual keyboard layouts are based on the traditional physical keyboard layout, which has the advantage of being able to quickly adapt to the user's usage habits. But the full QWERTY keyboard is not efficient for Chinese pinyin input. The main reason is that the distribution of common letters such as the vowels a, e, i, o, u on it is relatively scattered, and the positions of the keys are far apart. Some commonly used ones, such as ai, ei, ao, iao, uai, etc., need to move the fingers back and forth for a considerable distance when inputting by direct clicking or the more popu...

Problems solved by technology

But the shortcoming of this technical solution is that the key position setting of each letter key is slightly messy and complicated, and the input rules are also comparatively loaded down with trivial details, and the user must go through a period of memory and adaptation to fully grasp the virtual keyboard and its input method, which is not conducive to the Rapid marketing of technical solutions
