A virtual keyboard is a software-based keyboard that appears on a screen, allowing users to input text without a physical keyboard. It is commonly used on devices like smartphones, tablets, and computers, providing a flexible way to type. Users can tap on the keys displayed on the screen to enter characters, numbers, and symbols. Virtual keyboards can also offer features like predictive text and autocorrect, enhancing the typing experience. They are often customizable, allowing users to change layouts or themes. Some virtual keyboards support multiple languages, making them versatile tools for communication across different cultures and languages, such as English, Spanish, or Chinese.
