MOBILE DEVICE INDOOR NAVIGATION
First Claim
1. A method for indoor positioning in a venue comprising:
- receiving through a microphone of a mobile device an audio signal, the microphone capturing sound in the venue in a frequency range including a frequency range of human hearing;
in the audio signal, detecting at least one of plural different audio sources within the venue, and deriving an identification from the audio signal of the at least one of the audio sources;
determining a position of the mobile device in the venue based on the identification of the audio signal;
outputting a position based alert on an output device of the mobile device when the position of the mobile device is within a pre-determined position associated with the position based alert.

Abstract
A method for indoor navigation in a venue derives positioning of a mobile device based on sounds captured by the microphone of the mobile device from the ambient environment. It is particularly suited to operate on smartphones, where the sounds are captured using microphone that captures sounds in a frequency range of human hearing. The method determines a position of the mobile device in the venue based on identification of the audio signal, monitors the position of the mobile device, and generates a position based alert on an output device of the mobile device when the position of the mobile device is within a pre-determined position associated with the position based alert.

22. A system for indoor navigation in a venue comprising:
-
a configuration of audio sources, each transmitting a uniquely identifiable audio signal corresponding to a location; one or more computers for receiving audio detection events from mobile devices in the venue, the detection events providing identifying information of audio sources in the venue and calculating mobile device location from the detection events, monitoring position of the mobile devices at the venue, and sending an alert to the mobile devices when the position of the mobile devices is at a position associated with the alert, the position based alert being generated from a list of items that a user has expressed interest in. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)

31. A non-transitory computer readable medium, on which is stored instructions, which when executed by a computer, perform a method for indoor navigation comprising:
-
detecting audio source identifying information from an audio signal captured on a microphone; providing the source identifying information to a process for computing position of a mobile device in a venue; and generating a position based alert on an output device of the mobile device when the position of the mobile device is within a pre-determined position associated with the position based alert in the venue, the position based alert being generated from a list of items that a user has expressed interest in. - View Dependent Claims (32, 33)

34. A non-transitory computer readable medium, on which is stored instructions, which when executed by a computer, perform a method for indoor navigation comprising:
-
receiving audio source identifying information detected in audio captured from a microphone of a mobile device; computing position of a mobile device in a venue using the identifying information; and generating a position based alert for output on the mobile device when the position of the mobile device is within a pre-determined position associated with the position based alert in the venue, the position based alert being generated from a list of items that a user has expressed interest in. - View Dependent Claims (35)
