Patent ID: 8923995

Claim:
A method comprising: transmitting, by a processor of a portable device, a directional audio signal to a user, the directional audio signal generated by the portable device and associated with a spatial location relative to the user, the directional audio signal transmitted to the user independent of a physical location of the user; sensing, by a sensor of the portable device, movement of the portable device in a direction of a first spatial location with which the directional audio signal is associated, wherein the first spatial location direction of the sensed movement is one of a plurality of potential directions of sensed movement each of which corresponds to a specific modification in an operation performed by the portable device; identifying, by the processor, a modification of the operation currently being performed by the portable device that corresponds to the first spatial location direction of the sensed movement; and modifying, by the processor, an operation being currently performed by the portable device in accordance with the identified modification, at least in part, by adjusting the directional audio signal to a different spatial location around the user, and updating a visual display of the portable device based on the sensed movement of the portable device, wherein the updating the visual display comprises: updating a graphical user interface presented on the visual display, wherein the graphical user interface includes at least a list of selectable items each corresponding to content stored in the portable device.
