DIRECTIONAL AUDIO INTERFACE FOR PORTABLE MEDIA DEVICE
First Claim
1. A method for controlling a portable device by a user, the portable device having a processor and a sensor, the method comprising:
- receiving a directional audio signal by the user, the directional audio signal generated by the portable device;
moving the portable device by the user in response to the receiving of the directional audio signal;
sensing the movement of the portable device by the sensor; and
modifying an operation of the portable device in accordance with the sensed movement of the portable device.

Abstract
Methods and apparatus for a user to interact with and control a portable media device through an audio user interface. The audio user interface includes one or more audible control nodes perceived by the user to be spatially located at different points about the user of the portable media device. A sensor in the portable media device senses a movement of the portable media device by the user toward one or more of the audible control nodes. The operation of the portable device is modified in accordance with the sensed movement of the portable media device.

- 16. An audio user interface perceived by a user of a portable device to include one or more audible control nodes each perceived by the user to be spatially located at different points in a three dimensional region surrounding the user, wherein the portable device is controlled by the user moving the portable device in the direction of a spatial location in response to a directional audio signal received by the user, wherein the spatial location is that location in the three dimensional region that is perceived by the user as an origin of a selected one of the audible control nodes, the user perception resulting from the directional audio signal.

19. A method of providing the audio user interface at a portable device, comprising:
-
generating by a processor in the portable device a directional audio signal having a directional audio cue; communicating the directional audio signal to the user of the portable device through an audio output circuit; and sensing with a sensor in the portable device a movement of the portable device effected by the user in response to the communicated directional audio signal, wherein the processor associates the sensed movement of the portable device with a specific operational change of the portable device. - View Dependent Claims (20)
