1. A method comprising, with at least one computing platform:
- estimating a trajectory of a mobile device within an indoor environment based, at least in part, on one or more sensor measurements obtained at said mobile device;
obtaining at least one of one or more locations of one or more waypoints based, at least in part, on at least one input received from a user interface of said mobile device, said locations of said one or more waypoints being defined based, at least in part, on one or more objects identified in an electronic map of said indoor environment; and
affecting said estimated trajectory based, at least in part, on said one or more locations of said one or more waypoints.

Abstract
Various methods, apparatuses and/or articles of manufacture are provided which may be implemented to estimate a trajectory of a mobile device within an indoor environment. In some embodiments, the trajectory may be estimated without the use of any signal-based positioning information. For example, a mobile device may estimate such a trajectory based, at least in part, on one or more sensor measurements obtained at the mobile device, and further affect the estimated trajectory based, at least in part, on one or more objects identified in an electronic map of the indoor environment.
