Abstract: A touch pad disposed in an electronic display device is provided. The touch pad includes a sliding region, a first virtual-key region and a second virtual-key region both adjacent to the sliding region, a first vibrator and a second vibrator. The sliding region are capable of sensing a dragging action, the first virtual-key region and the second virtual-key region are capable of sensing a pressing action, and the second virtual-key region corresponds to one side of the first virtual-key region. The first vibrator and the second vibrator are respectively disposed underneath the first virtual-key region and the second virtual-key region. When the first virtual-key region senses the pressing action, the first vibrator generates vibration. When the second virtual-key region senses the pressing action, the second vibrator generates vibration.
