摘要:
A control and data entry device adapted for use in for electronic devices such as portable computers, PDA's, cell phones, MP3 players and the like. The control and data entry device includes a tiltable member or similar structure carrying an electrically conductive member spaced from multiple sense electrodes disposed on a circuit substrate. In one embodiment, capacitances between the electrically conductive member and the electrodes are measured to provide information concerning the tiltable member's orientation relative to the sense electrodes. The tiltable member may be manipulated by a users finger to tilt such member slightly and thereby effect scrolling functionality, thereby simulating the operation of circular capacitive touch pads known in the art. Switches may also be included, responsive to greater tilting of the tiltable member, thereby to effect clicking functionality. In some embodiments, a rotatable knob may be used to effect scrolling functionality.
