Computer mouse comes with the most common standard functions: two buttons (left and right) and a scroll wheel, which can also act as a third button. Mouse typically controls cursor movement in two dimensions of the graphical user interface (GUI). Mouse movement truns the hand backward and forward, left and right in equivalent electronic signals, which, in turn, are used to move the cursor.
The relative movement of the mouse on the surface is attached to the cursor (click) position on the screen that indicates the point at which the user performed the event, so that the movement of hands are played from the pointer.
