Be sure the computer is on a table or desktop rather than on your lap or the bed. You need to have a built-in webcam or standard USB webcam on or near the monitor so it is pointing at you.

Start up Camera Mouse. Your moving image will appear in the Camera Mouse window. Use the mouse to click on a feature on your face to track. Some unique area of the face. We usually use the inside edge of an eyebrow or eye or the area between the nose and the mouth. A small green square appears at the feature being tracked. As you move your head the square moves with it in the image.

Now press the Ctrl key or the F9 key or just wait for 4 seconds without moving the mouse (“Auto start”). The Camera Mouse program takes over control of the mouse pointer on the screen. As you move your head the mouse pointer moves accordingly. If you move the mouse itself (or press the Ctrl key or F9 key) the control returns to the mouse.

You can adjust the settings by clicking on the Camera Mouse Settings button at the bottom of the window. Here you can change the gains and turn on clicking. Clicking is done using “dwell time,” by holding the mouse pointer within a small area of the screen for a second or two. Or you can click in the regular way using the mouse button or a switch.
