A virtual keyboard based on a touch screen device and its input method

Abstract

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. 5 English letter keys are displayed on the virtual keyboard; and the letter keys a, e, i, o, u are arranged continuously; the input method takes 5 vowel letters as index input and other words arranged in order according to 26 English alphabets Consonant letters, and make full use of gestures such as clicking, sliding or dragging on the touch screen to input Chinese pinyin, especially for the input of compound finals and nasal finals with multi-letter combinations. The outstanding advantages of the present invention are that the key layout of the virtual keyboard is novel and simple in design, takes up little screen space, and the definition of input rules is not complicated, which is beneficial to technical realization and market promotion. The present invention can be applied to the information input of the touch screen device.

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 smartphones, most of the common virtual keyboards are laid out in the form of QWERTY full keyboard or digital nine-square grid. These two virtual keyboard layouts are based on the layout of traditional physical keyboards. Traditional usage habits. [0003] However, virtual keyboard layout methods such as QWERTY full keyboard and digital nine-square grid cannot be applied to small-sized touch screen devices like Apple smart watches. Taking the touch screen size of Apple’s 1st generation smart watch as an example, the screen size is about 1.97 inches to 2.2 inches. That is, the side length is between 38mm and 42mm, remove the unusable area near the edge of the screen, and the area left for setting buttons is only between 36...

[0003] However, virtual keyboard layout methods such as QWERTY full keyboard and digital nine-square grid cannot be applied to small-sized touch screen devices like Apple smart watches. Taking the touch screen size of Apple’s 1st generation smart watch as an example, the screen size is about 1.97 inches to 2.2 inches. That is, the side length is between 38mm and 42mm, remove the unusable area near the edge of the screen, and the area left for setting buttons is only between 36mm and 40mm. The virtual keyboard layout of the QWERTY full keyboard is obviously a Not applicable; although the number of keys of Jiugongge virtual keyboard is much less than that of QWERTY full keyboard, considering its high repetition rate, it is necessary to reserve screen space for selecting candidate Chinese character pinyin combinations, and additional space is needed Display candidate words or words and other function keys, including confirmation key, space bar, delete key, number symbol switching key, etc., which makes the Jiugongge virtual keyboard layout unapplicable, even if it is barely applied, it will make the input experience poor

[0004] At present, there is no public virtual keyboard and its input method that can be well applied to devices with small touch screens similar to Apple smart watches. In addition to the voice input method, there is no Chinese character that can be applied to it. Pinyin input technical solutions, so a new technical solution is urgently needed to solve this problem
