A video trackpad is a computer input device that allows users to control a cursor on a computer screen by moving their finger across a touch-sensitive surface. Video trackpads are often used on laptop computers and other portable devices.
To use a video trackpad, simply place your finger on the touch-sensitive surface and move it in the direction you want the cursor to move. The cursor will follow the movement of your finger. You can also use the trackpad to perform other actions, such as clicking, scrolling, and zooming.
