Techniques for processing perceived routability constraints that may or may not affect movement of a mobile device within an indoor environment
First Claim
Patent Images
1. A method for supporting mobile device positioning on a computing device external to said mobile device, the method comprising:
- receiving an electronic map for an indoor environment, wherein at least a portion of said electronic map comprises displayable image data;
selecting at least one perceived routability constraint based, at least in part, on said displayable image data;
setting a measure of confidence for said at least one perceived routability constraint based, at least in part, on said displayable image data, wherein the measure of confidence corresponds to an estimated likelihood that said at least one perceived routability constraint represents an actual physical obstacle to navigation; and
transmitting at least said measure of confidence to said mobile device for use by said mobile device in estimating a trajectory of said mobile device within said indoor environment.

Abstract
Techniques are provided which may be implemented using various methods, apparatuses and/or articles of manufacture to provide or otherwise support mobile device positioning. The mobile device positioning may be based, at least in part, on one or more perceived routability constraints that may or may not affect actual movement of a mobile device within an indoor environment.

10. A computing device for use in supporting mobile device positioning, the computing device comprising:
-
memory; a communication interface; and one or more processing units to; access an electronic map for an indoor environment via said memory, wherein at least a portion of said electronic map comprises displayable image data; select at least one perceived routability constraint based, at least in part, on said displayable image data; set a measure of confidence for said at least one perceived routability constraint based, at least in part, on said displayable image data, wherein the measure of confidence corresponds to an estimated likelihood that said at least one perceived routability constraint represents an actual physical obstacle to navigation; and initiate transmission, via said communication interface, of at least said measure of confidence to said mobile device for use in estimating a trajectory of said mobile device within said indoor environment. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
