Problems solved by technology

This type of input method is also due to problems such as small touch screen, recognition technology level, and too scribbled, resulting in a large number of candidate characters, and it is even difficult to complete accurate input at one time, that is, the input accuracy is low

Embodiment Construction

[0090] The invention can be applied to electronic products with touch screens such as smart phones and tablet computers.

[0091] When applying, it is first necessary to choose the size of the stroke dot matrix. Under the premise that it can accommodate strokes and lines, the size of the dot matrix depends on the specific application instance. For example, when only English letters are input, because the strokes of English letters are relatively simple, they can be accommodated with a smaller dot matrix, so both mobile phones and tablet computers can choose 3×3 dot matrix. When inputting Chinese characters on the touch screen of the mobile phone, because the touch screen of the mobile phone is generally small, a 3×3 dot matrix can also be adopted. When inputting Chinese characters on the tablet dot brain, a larger dot matrix such as 10×12 can be used, and the strokes can be drawn and connected according to the original relative positional relationship of the strokes of the Chi...

Abstract

The invention discloses a character input method for a touch screen based on a rectangular lattice. The method comprises the following steps that: 1, a virtual rectangular lattice which is called a stroke lattice is established in advance on the touch screen; 2, in a writing process on the touch screen, an inputer selects corresponding lattice points from the stroke lattice according to character stroke writing habits, and connects the lattice points to form a connecting line of lines similar to strokes, wherein the connecting line is called a stroke connecting line; 3, a computer detects a motion trail formed by touch operations of the inputer on the touch screen, and identifies the stroke connecting line; 4, the computer converts the identified stroke connecting line into the corresponding strokes; and 5, the computer matches an input stroke sequence consisting of one to a plurality of strokes with characters to obtain all matched characters for input. The input method is consistent with the writing habits of the inputer; the inputer is only required to write on the stroke lattice by imitating the strokes of the characters; and writing operations of the inputer on the stroke lattice are constrained.

Description

technical field [0001] The invention relates to a text input method, in particular to a touch screen text input method based on a rectangular dot matrix, and belongs to the technical field of text information processing. Background technique [0002] Currently, the input methods used on the touch screens of various electronic products such as smart phones and tablet computers can be mainly divided into two types based on virtual keyboards and based on handwriting recognition. [0003] An input method based on a virtual keyboard, that is, an input method that displays a virtual keyboard on the touch screen for clicking and inputting. If this type of input method uses a full keyboard layout similar to a PC keyboard, because the touch screen is small and there are many keys, it is difficult for the input user to quickly and accurately click on the virtual keys; if a compressed keyboard with multiple letters or symbols corresponding to one virtual key is used, the input user wi...
