Key position functional definition method of digital keyboard

Abstract

The invention discloses numeric keyboard key mapping function definition method. It is based on current numeric keyboard key press standard and character mapping method. It can be suited for various entering, realize direct switching for different input states to greatly increase input speed, has unified key mapping function definition for user to fast master and expertly use.

Description

【Technical field】 [0001] The invention discloses a key position function definition method of a numeric keypad, which adds a function-specific key position definition on the basis of the existing key position standard and character mapping method of the numeric keypad. It is especially suitable for communication equipment, information home appliances, handheld equipment and other fields that need to use the numeric keypad for text input. 【Background technique】 [0002] Since the number keys 0 to 9 on the number keyboard often require fewer keys than the basic code table for specific text input, one or more basic codes will be mapped to a number key at this time. At present, there are two schemes for mapping 26 letters based on pinyin to numeric keys in the national standard: 10-key setting mode and 8-key setting mode. Both of these two schemes only define the mapping rules of the 0-9 Arabic numeral keys in principle. For other keys, such as the arrow keys (up [↑], down [↓],...

Problems solved by technology

Both of these two schemes only define the mapping rules of the 0-9 Arabic numeral keys in principle. For other keys, such as the arrow keys (up [↑], down [↓], left [←], right [→]) , the confirmation key [OK], the return key [C], the [*] key, and the functions of the [#] key are not defined, so there is a lot of randomness and inconsistency in the definition of key positions in various input methods. Determinism, leading to confusion and irregularity in the definition of key functions

After users are familiar with the functions of keyboard keys in a certain arrangement, if they replace a new keyboard, they will often feel at a loss due to the change of key functions.

At the same time, in the process of inputting a compound sentence (a sentence containing words, letters, numbers, and symbols), it is often necessary to switch the input method or input mode frequently. The input process is cumbersome and the input experience is poor.
