Double-key single-knob combining character input method based on embedded equipment

Abstract

The invention provides a double-key single-knob combining character input method based on embedded equipment. By the application of the method, the operation is easy and convenient, and the character input equipment is concise in structure. The method comprises the following steps: (1) starting the character input mode of keys and a knob; (2) rotating the knob A, enabling characters in a character set Phi in the current character input positions to appear in sequence, when the required characters appear, stopping rotating, and namely considering that the characters are selected; (3) then pressing the character input position selection key, enabling the input positions to move in sequence, when the positions of the characters required to be input are reached during movement, stopping pressing, and namely considering that the positions correspond to the characters selected in the step (2); (4) sequentially repeating the step (2) and the step (3) until the required character string is completely and correctly displayed; (5) pressing the enter key, and namely informing a system of completing input of the required character string.

Description

technical field [0001] The invention relates to a character input device and method based on an embedded device. Background technique [0002] The mobile phone is the platform where people use embedded devices to input the most characters. It uses ten number keys to input 26 letters and numbers, and a switch button is used to select whether the nine input keys are to input letters or numbers. When in the number input mode, these ten keys are in the number input mode, representing their corresponding number characters; when in the letter input mode, the characters corresponding to the numbers from 0 to 9 are as follows: 0 (empty); 1 ( NULL); 2(ABC); 3(DEF); 4(GHI); 5(JKL); 6(MNO); 7(PQRS); 8(TUV); 9(WXYZ). When it is necessary to input a specific character, select the number button with the character and press it continuously, and the letters of the character will appear in a cycle, thereby realizing the input of letters. The traditional airborne cockpit input device is to ...

Problems solved by technology

[0003] General-purpose aircraft is a type of small airborne equipment platform, which cannot be equipped with sufficient auxiliary input equipment like ground equipment

On such small airborne devices, it is often necessary to input specific characters to realize man-machine command interaction, such as inputting English letters, numbers or specific characters, etc., but as far as the device itself is concerned, it cannot provide enough buttons, knob to support entering these characters (or strings) individually
