A virtual keyboard is a software interface that allows users to input text and commands using a graphical representation of a keyboard displayed on the screen. It's particularly useful for touchscreen devices where a physical keyboard is not available.
Windows users can access a virtual keyboard by searching 'on-screen keyboard' in the start menu.
Virtual input devices are used to provide users with a way to interact with computing devices without the need for a physical .
Virtual Mouse
A virtual mouse provides a graphical representation of a mouse pointer that users can control using input methods such as touchscreens or trackpads.
It allows users to interact with graphical user interfaces (GUIs) without a physical mouse.
Some devices use eye-tracking technology as a virtual input device, allowing users to control the device by moving their .
Virtual Joystick & Gamepad
Virtual joysticks and gamepads simulate the functionality of physical controllers for gaming and other applications. They allow users to control on-screen actions using touch or keyboard inputs, providing a gaming experience similar to using a physical game controller.
This is useful for playing games that are designed for consoles on a PC.
Gesture recognition technology is another form of virtual input device that allows users to control devices through hand and body .
