LOCATION ESTIMATION USING A MOBILE DEVICE
First Claim
1. A method, comprising:
- receiving, by a device comprising one or more processors, one or more signature measurements associated with an indoor environment, wherein the device is associated with a user;
receiving, at the device, one or more motion tracking measurements that are associated with relative motion of the device with respect to one or more aspects of the indoor environment and relative motion of the device with respect to the user;
associating, by the device, the one or more signature measurements with one or more virtual landmarks identified within the indoor environment; and
determining a location of the device based on the one or more signature measurements and the one or more motion tracking measurements.

Abstract
The present disclosure relates to computer-implemented systems and methods for location estimation using a mobile device. An example method may include receiving, at a device, one or more signature measurements associated with an indoor environment. Additionally, the device may be associated with a user. The method may also include receiving, at the device, one or more motion tracking measurements to measure relative motion associated with the device and the user. Furthermore, the method may include associating the one or more signature measurements with one or more virtual landmarks identified within the indoor environment. The method may further include determining a location of the user based on the one or more signature measurements, the one or more motion tracking measurements, and the one or more virtual landmarks.

13. A system, comprising:
-
a memory storing instructions; a processor to execute the instructions to; receive one or more signature measurements associated with an indoor environment; receive one or more motion tracking measurements that are associated with relative motion of a device with respect to the indoor environment and relative motion of the device with respect to a user associated with the device; associate the one or more signature measurements with one or more virtual landmarks identified within the indoor environment; and determine a location of the user based on the one or more signature measurements, the one or more motion tracking measurements, and the one or more virtual landmarks. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A computer readable medium storing instructions, that when executed by a processor, cause the processor to:
-
receive, at a device, one or more signature measurements associated with an indoor environment, wherein the device is associated with a user; receive, at the device, one or more motion tracking measurements that are associated with relative motion of the device with respect to the indoor environment and relative motion of the device with respect to the user; associate the one or more signature measurements with one or more virtual landmarks identified within the indoor environment; generate a database to store one or more signature-landmark associations between the one or more signature measurements and the one or more virtual landmarks; and determine a location of the user based on the one or more motion tracking measurements and the one or more virtual landmarks, wherein the one or more virtual landmarks correspond to one or more coordinates and respective combinations of the one or more signature measurements. - View Dependent Claims (21, 22, 23)

24. An apparatus, comprising:
-
a signature-landmark association module configured to receive one or more signature measurements associated with an indoor environment, the signature-landmark association module further configured to associate the one or more signature measurements with one or more virtual landmarks identified within the indoor environment; a relative motion tracking module configured to receive one or more motion tracking measurements that are associated with relative motion of a device with respect to the indoor environment and relative motion of the device with respect to a user associated with the device; and a localization and database generation module to determine a location of the user based on the one or more signature measurements, the one or more motion tracking measurements, and the one or more virtual landmarks. - View Dependent Claims (25, 26, 27, 28)
