Point-and-click devices are computer input devices that allow users to interact with a computer by pointing and clicking on objects on the screen. The most common type of point-and-click device is the mouse, which is a handheld device with two buttons and a scroll wheel. By moving the mouse around on a flat surface, users can move the cursor on the screen and click on objects to select them. Point-and-click devices are used in many different applications, from gaming to graphic design to office productivity.
