USER LOCATION SYSTEM
First Claim
Patent Images
1. A method, comprising:
- determining, via a processor, an edge density from one or more images of an environment, the one or more images provided from an electronic device of a user in the environment;
determining, via the processor, a location of the edge density;
determining, via the processor, a location of the user in the environment based at least on the determined location of the edge density;
determining, via the processor, uniformity of the one or more images;
determining further, via the processor, the location of the user in the environment based at least on the determined uniformity of the one or more images; and
outputting, via an interface communicatively coupled to the processor, to a control device of the environment, the determined location of the user in the environment.

Abstract
A user location system (ULS) can use images, such as video or still images, captured from at least one camera of an electronic device, such as a mobile device, to determine, via at least edge detection and image uniformity analysis, location of a user in an environment, such as in a cabin of a vehicle. The determined location of the user can then be used as an input to control at least one aspect of the environment. In the case of a vehicle, such input may be used to facilitate control of speed, safety features, climate, and/or audio playback, for example.

18. A system, comprising:
-
a processor; processor executable instructions stored in memory executable to; determine an edge density and an edge density location in one or more images of a vehicle; determine a location of a passenger in the vehicle based at least on the determined edge density and the determined edge density location; and determine uniformity of the one or more images using one or more of an entropy calculation or a transformation of the one or more images from a spatial domain to a frequency domain; and determine further the location of the passenger based at least on the determined uniformity of the one or more images; and an interface operable to output to a control device of the vehicle, the determined location of the passenger. - View Dependent Claims (19)

20. A computer readable medium comprising instructions, the instructions executable to:
-
determine an edge density and an edge density location in a front-facing image of a user of an electronic device, the front-facing image provided by the electronic device; determine a location of the user based at least on the determined edge density and the determined edge density location; determine uniformity of the front-facing image using one or more of an entropy calculation or a transformation of the front-facing image from a spatial domain to a frequency domain; determine the location of the user based at least on the determined uniformity of the front-facing image; and confirm the location of the user based at least on brightness of a rear-facing image, the rear-facing image provided by the electronic device.
