1. A method for providing contextually-targeted responses to observers of an electronic sign system, the electronic sign system including a sign and a camera for depicting observers of the sign, the method employing one or more processors configured by software instructions to perform acts including:

  • analyzing image data from the electronic sign system camera to determine a first location of a first mobile observer, and a second location of a second mobile observer;

    analyzing image data from the electronic sign system camera, that depicts the first and second observers, to determine demographic attributes of said observers;

    determining first response data for delivery to the first observer based on one or more of said demographic attributes of the first observer, and determining second response data for delivery to the second observer based on one or more of said demographic attributes of the second observer, the second response data being different than the first response data;

    receiving image data captured by a viewer'"'"'s portable device, the image data depicting the electronic sign;

    determining, from viewpoint-dependent distortion of known imagery presented on the sign as depicted in the received image data, whether it was captured from the first location or the second location, and thereby to determine whether said viewer is the first or second observer; and

    sending the first or second response data to said viewer, based on whether the viewer was determined to be the first observer or the second observer;

    wherein demographically-relevant response data is directed to a particular observer as a consequence of the sign system capturing imagery depicting observers, and the particular observer'"'"'s device capturing imagery depicting the sign.
