    Abstract: A vehicle includes a positioning system configured to determine a position. The vehicle includes a memory configured to store information associated with one or more landmarks. The information includes an audio icon associated with a landmark, and the landmark is located at a landmark location. The vehicle includes a processor configured to retrieve the audio icon based on the position and to render an audio signal based on the audio icon into a three-dimensional audio space within the vehicle. The vehicle further includes two or more transducers configured to output a spatial auditory sound in the three-dimensional audio space based on the audio signal. The spatial auditory sound enables perception of the landmark location relative to a location within the vehicle.

    Abstract: In general, techniques are described for locating a user using an ultrasound mesh. The techniques may be performed by an interactive system comprising one or more processors. The processors may be configured to determine an amplitude of a first ultrasound signal emitted by one or more transducers and received by a microphone. This first ultrasound signal may be of a first frequency. The processors may then determine an amplitude of a second ultrasound signal emitted by the one or more transducers and received by the microphone. The second ultrasound signal may be of a second frequency different from the first frequency. The processors may be further configured to determine a location of the microphone relative to the one or more transducers based at least on the determined amplitude of the first ultrasound signal and the determined amplitude of the second ultrasound signal.

    Abstract: A user interface, methods and article of manufacture each for selecting an audio cue presented in three-dimensional (3D) space are disclosed. The audio cues are audibly perceivable in a space about a user, where each of the audio cues may be perceived by the user as a directional sound at a distinct location from other audio cues in the space. Selection of a specific audio cue is made based on one or more user gestures. A portable electronic device may be configured to present the audio cues perceived by a user and detect certain user gestures to select audio cues. The audio cue selection can be used to control operation of the portable device and/or other associated devices.
