Touch screen device-based virtual keyboard and input method thereof

Abstract

The invention relates to the technical field of input methods, in particular to a touch screen device-based virtual keyboard and an input method thereof. 5 English letter keys are displayed on the virtual keyboard; and the letter keys a, e, i, o and u are continuously arranged. According to the input method, other consonant letters arranged according to an alphabet sequence of 26 English letters are input by taking 5 vowel letters as indexes, Chinese character pinyin is input by fully utilizing a gesture action of clicking-pressing, sliding, dragging or the like of a touch screen, and especially convenience is brought for input of compound vowels and nasal vowels of multi-letter combinations. The virtual keyboard and the input method have the outstanding advantages that the key layout of the virtual keyboard is novel and simple in design, the occupied screen space is small, and the definition of input rules is simple, thereby being favorable for technical implementation and market promotion. The virtual keyboard and the input method can be applied to information input of a 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
