1. A headset comprising:
- a microphone;
a speaker;
a finger pad on an exterior of the headset on which a finger of a headset wearer is placed;
an optical line scanner, wherein the optical line scanner scans the finger pad and outputs a series of successive images of the finger placed on the finger pad; and
a processor, wherein the processor processes the series of successive images to detect relative motion of the finger on the finger pad or detect tapping of the finger on the finger pad.

Abstract
A headset includes a finger pad on an exterior of the headset on which a finger of a headset wearer is placed. The headset includes an optical line scanner which scans the finger pad and outputs a series of successive images of the finger placed on the finger pad. A headset processor processes the output of the optical line scanner to detect relative motion of the finger on the finger pad or detect tapping of the finger on the finger pad.

1. A headset comprising:
-
a microphone; a speaker; a finger pad on an exterior of the headset on which a finger of a headset wearer is placed; an optical line scanner, wherein the optical line scanner scans the finger pad and outputs a series of successive images of the finger placed on the finger pad; and a processor, wherein the processor processes the series of successive images to detect relative motion of the finger on the finger pad or detect tapping of the finger on the finger pad. - View Dependent Claims (2, 3, 4, 5, 6)

7. A headset comprising:
-
a finger receiving means for placement of a user finger; an optical line scanning means for scanning the finger receiving means on a headset housing exterior and providing an output of successive images of the finger receiving means; a capacitive sensing means overlaid on the finger receiving means for sensing placement of a user finger to detect a false trigger of the optical line scanning means; and a processing means for processing the output of successive images of the finger receiving means to determine a relative movement of a user finger across the finger receiving means or determine a tapping of the user finger on the finger receiving means, wherein the processing means modifies a headset control operation responsive to the relative movement of the user finger or the tapping; a first transducer means for receiving a user speech signal; and a second transducer means for outputting an audio signal. - View Dependent Claims (8)

9. A method for receiving user input at a headset comprising:
-
providing a transparent finger pad on a headset housing for receiving a user finger; providing an optical line scanner disposed within the headset housing; scanning the transparent finger pad with the optical line scanner to output a series of successive images; processing the series of successive images to determine a relative movement of a user finger across the transparent finger pad; and modifying a headset control operation responsive to the relative movement of the user finger. - View Dependent Claims (10, 11, 12, 13)

14. A headset comprising:
-
a finger receiving means for placement of a user finger; an optical scanning means for scanning the finger receiving means on a headset housing exterior and providing a sequence of electrical signals associated with successive line scan images of the finger receiving means; a capacitive sensing means overlaid on the finger receiving means for sensing placement of a user finger to detect a false trigger of the optical line scanning means; and a processing means for processing the sequence of electrical signals to determine a relative bi-directional movement of a user finger across the finger receiving means along a single axis or determine a tapping of the user finger on the finger receiving means, wherein the processing means modifies a headset control operation responsive to the relative bi-directional movement of the user finger or the tapping; a first transducer means for receiving user speech; and a second transducer means for outputting an audio signal. - View Dependent Claims (15)
