Touch input method of numeric keyboard

Abstract

The invention discloses a touch input method of a numeric keyboard. wherein the numeric keyboard consists of ten numeric keys, a switching key and a symbol key, one numeric key is mapped with a plurality of character keys, and the input method comprises the following steps of: after a user touches the numeric keys, obtaining a pressing point coordinate, a lifting point coordinate and a direction vector between the pressing point coordinate and the lifting point coordinate of touch; selecting a numeric key corresponding to the coordinate of the pressing point as a key triggered at this time; when the length of the direction vector is within a set threshold range, determining the trigger as the mapping; when the length of the direction vector exceeds a set threshold value range, judging upper, lower, left and right directions from the direction angle of the direction vector, and respectively determining that the trigger is upper mapping, lower mapping, left mapping and right mapping; andoutputting the character keys in one-to-one correspondence with the mappings. According to the invention, Chinese characters can be input through phonetic notation quickly and accurately through thebasic numeric keyboard.

Description

technical field [0001] The invention relates to an input method, in particular to a touch input method of a numeric keyboard. Background technique [0002] Input method software is a kind of text input software installed on computers or other devices (mobile phones, tablet computers), that is, input method applications used when writing text or documents. As an input tool, input method software is an indispensable core software for computers and electronic equipment, and a medium for users to interact with machines. An important symbol of mode change and innovation. [0003] With the advent of the touch screen era, the input method of smart handheld devices, as a fast, easy-to-operate and user-friendly text system, is not only a necessary input tool for smart handheld devices, but also will change the process of user experience in the era of social networking. At present, the keyboard types of the input method software for handheld devices are roughly divided into two type...

Problems solved by technology

However, this will cause the following problems: for a large-screen handheld device, the user cannot complete the input of a word with one hand; for a small-screen handheld device, each button area is very small, and various functional areas , it is difficult for the user's fingers to accurately press the selected key; in addition, although the various functional areas increase the functions of the keyboard, the area of ​​each functional area is small, and the content that can be displayed is less. Such functions The expansion of the functional area is of little significance; finally, according to the user's input habits, users of many functional areas rarely use them, or even don't know how to use them. Such functional area expansion can be said to be a waste of space, making the originally narrow screen more crowded
