Key-restricted soft keyboard character input method

Abstract

The invention discloses a key-restricted soft keyboard character input method. The key-restricted soft keyboard character input method is characterized in that a soft keyboard display panel adopting multiple input methods is triggered by four-key input equipment, wherein the four keys include a composite function key, a left shift key, a right shift key and an enter key; layouts and configuration contents of the different input methods are displayed by the soft keyboard display panel, and the functions of the upper shift key, the lower shift key and a cancel key are simulated according to the functions of the four keys and the key combination to input characters; the soft keyboard display panel including multiple input methods is divided into an editing input region, a first function region, a second function region and a keyboard character region. According to the key-restricted soft keyboard character input method, numbers, uppercase and lowercase letters and symbols are inputted by adopting the least keys on the basis of the four-key input equipment and the soft keyboard display panel including multiple input methods, and thus the input method is convenient to operate and the operating efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of character input, in particular to a soft keyboard character input method with restricted keys. Background technique [0002] Some collection and monitoring equipment used in industry does not need to display too much content on the terminal equipment, so the design of human-computer interaction often considers the design of small LCD and fewer buttons. Especially some terminal equipment in the water conservancy industry, such as water and rain telemetry terminals, etc., do not require complicated local operations, and require miniaturization and low power consumption design. Therefore, it is impossible to adopt large-size or high-resolution liquid crystals and too many keys. In this way, it is still feasible to input numbers through simple direction keys and confirmation function keys, but it is too troublesome to input letters and symbols. In the past, this type of input to such terminal equipmen...

Problems solved by technology

However, in the case of field equipment maintenance, computers, PDAs, etc. cannot be used for a long time without mains power, and the problem of inconvenient operation still exists.

[0003] Even though some terminals can realize the input of numbers, letters, and symbols, it is generally a one-dimensional selection. Use the arrow keys to display numbers, letters, and symbols in a certain sequence, wait until the required characters appear, and then choose to move the cursor Carry out the next input, and so on, until the end of all character input, this method greatly increases the number of key input, and it is not intuitive, the user does not know what the next character is when input selection, especially when input This is especially true when notation, resulting in low productivity
