A pointing device comprises a substrate with an electrically conductive surface and a resilient boot. The resilient boot resiliently supports a resistive surface to contact the electrically conductive surface in a pressed mode when a force is applied to push and deform the resilient boot against the electrically conductive surface. The resilient boot is made of a resistive rubber material. The resistive surface has a voltage variance and is curved to be rocked on the electrically conductive surface in the pressed mode. The voltage variance is detected on the electrically conductive surface and a variable signal is generated and processed. At least one inner switch is provided near the center region of the electrically conductive surface and the inner switch is activated by the resistive surface in the pressed mode. When the force is removed, the resistive resilient boot returns to its undeformed state and the resistive surface is spaced from the electrically conductive surface in a rest mode.
