Most keypad types include number keys from 0 to 9, special character keys * and #, and a small number of function keys, such as confirm, select, start, call, and hang up. Due to the small size of these devices, it is usually inconvenient to equip them with full-letter and symbol keyboards, and the input of symbols such as letters is realized through a small keyboard, such as a numeric keyboard. Since the total number of commonly used symbols and letters is more than the total number of keyboard keys, each character cannot be equipped with a key button independently. The ...
