This option allows you to change the relationship between the distance that the mouse pointer moves on the screen and the relative movement of the physical device itself (which may be a mouse, trackball, or some other pointing device.) A high value for the acceleration will lead to large movements of the mouse pointer on the screen even when you only make a small movement with the physical device. Selecting very high values may result in the mouse pointer flying across the screen, making it hard to control.
Esta opción permítelle cambiar a relación existente entre o movemento do punteiro na pantalla e o movemento do dispositivo no espazo físico (calquera dispositivo de apuntamento). Un valor alto de aceleración causará que movementos pequenos do dispositivo produzan movementos longos do punteiro na pantalla. Os valores moi altos poden causar un control difícil do rato.
