What Does Onscreen Keyboard Mean?
An onscreen keyboard is a software-based keyboard that is available in most operating systems, especially Microsoft Windows, and in other applications. An onscreen keyboard allows users to type text using a joystick or a pointing device. Apart from improving input options for users who are physically challenged, it also serves as an alternative to a physical keyboard.
Techopedia Explains Onscreen Keyboard
An onscreen keyboard displays a virtual keyboard on the screen for users to enter input. It can be operated with the help of any pointing device such as a mouse, pen, joystick, etc. The keyboard is often resizable and customizable, allowing the typing mode, font, etc., to be changed as needed. In certain onscreen keyboards, especially those from Windows 7 and later versions, they are equipped with a predictive text engine, which helps in predicting the words the users may type.
