The user acts as though a physical mouse were present and the laser beam is intersected by the hand, and parts of the hand are shown up as bright spots of light that change position as the hand moves. The built-in camera then interprets the changes in position of the hand and fingers and translates them as moves of the mouse and clicks on the two buttons, and the cursor on the screen moves as if the user was operating a physical mouse.</blockquote>
