An Input Method is a software tool that allows users to enter text in languages that have complex scripts or characters, such as Chinese, Japanese, or Korean. It enables the conversion of keystrokes into the desired characters, making it easier for users to type in their native languages on standard keyboards. Input methods can include various techniques, such as phonetic typing, where users type sounds that correspond to characters, or visual input, where users select characters from a list. These methods enhance accessibility and usability for multilingual users, ensuring effective communication across different languages.
