Abstract
The present invention discloses an input equipment with a sensed movement feedback, which comprises a pressure sensor pad having a through hole at the center, a rolling ball disposed in the through hole with part of the rolling ball exposed and protruded therefrom, and at least one driver contacting with the surface of the rolling ball. The sensor pad will produce a signal according to a pressing force exerting thereon and transmit the signal to a control circuit of the input equipment, enabling the control circuit to produce a rolling signal for activating the driver to move the rolling ball in a direction proportion to the pressing force. Thus, the user can sense the direction and speed of the cursor movement on the screen from sensing the rolling movement of the rolling ball.
