Collaborative navigation techniques for mobile devices

摘要

Various methods, apparatuses and/or articles of manufacture are provided which may be implemented to perform and/or otherwise support collaborative navigation between a plurality of mobile devices. In one example, a first mobile device, in response to a determination that at least a second mobile device is located within a threshold distance of the first mobile device, may obtain a navigation parameter indicative of an initial position and/or movement of the second mobile device which was determined based, at least in part, on a measurement from a sensor at the second mobile device. The first mobile device then affect a determined position and/or movement of the first mobile device based, at least in part, on the navigation parameter.

1. A method for performing collaborative navigation, at a first mobile device, between said first mobile device and a second mobile device, the method comprising:
receiving a signal, from said second mobile device, at said first mobile device; determining, based on a measurement characteristic of said signal received at said first mobile device, that a second mobile device is located less than at a threshold distance from said first mobile device; obtaining, at a communication interface, navigation parameter indicative of an initial position of said second mobile device or a movement of said second mobile device, said initial position of said second mobile device or a movement of said second mobile device being determined based, at least in part, on a measurement from a sensor at said second mobile device; and determining an estimated position of said first mobile device, using said navigation parameter, one or more navigation constraints identified in an electronic map corresponding to an indoor environment, and said threshold distance between said second mobile device and said first mobile device, to limit said estimated position, movement determination, or both of said first mobile device within said indoor environment.
