1. A method, implemented by computing functionality, for assessing movement of a mobile device associated with a subject in a scene, comprising:

  • receiving internal-assessed (IA) movement information regarding the movement of the mobile device from at least one position-determining device provided by the mobile device;

    receiving external-assessed (EA) movement information from at least one monitoring system which captures images of the scene containing the subject and the mobile device;

    comparing the IA movement information with the EA movement information for a candidate object associated with the subject using a candidate orientation of the mobile device;

    repeating, at least one time, said comparing with respect to another candidate object, each iteration of said comparing producing correlation results;

    determining, based on the correlation results for each candidate object, at least one matching object which is associated with the mobile device by selecting a candidate object with the strongest correlation results as a matching object; and

    fusing the IA movement information with the EA movement information to yield more precise IA and EA movement information comprising a more precise location in space and a more precise orientation in space for the at least one matching object;

    performing an environment-specific action using the fused IA and EA information for the matching object based on an outcome of said determining,said receiving of the IA movement information, receiving of the EA movement information, comparing, repeating, determining, fusing and performing being implemented by the computing functionality.
