Abstract
A user with a cell phone interacts, in a personalized session, with an electronic sign system. In some embodiments, the user'"'"'s location relative to the sign is discerned from camera imagery—either imagery captured by the cell phone (i.e., of the sign), or captured by the sign system (i.e., of the user). Demographic information about the user can be estimated from imagery captured acquired by the sign system, or can be accessed from stored profile data associated with the user. The sign system can transmit payoffs (e.g., digital coupons or other response data) to viewers—customized per user demographics. In some arrangements, the payoff data is represented by digital watermark data encoded in the signage content. The encoding can take into account the user'"'"'s location relative to the sign—allowing geometrical targeting of different payoffs to differently-located viewers. Other embodiments allow a user to engage an electronic sign system for interactive game play, using the cell phone as a controller.

21. A method involving an electronic sign, viewed by a first observer, comprising the acts:
-
obtaining first contextual data relating to the first observer; defining a first digital watermark signal that takes into account the first contextual data; steganographically encoding first image data in accordance with the first digital watermark signal; and presenting the encoded image data on the electronic sign. - View Dependent Claims (22)

23. A method in which an electronic sign presents content that is viewed by plural observers, the method comprising the acts:
-
using a first camera-equipped device conveyed by a first observer, viewing the presented content and capturing first image data corresponding thereto, determining first identifying data by reference to the captured first image data; using a second camera-equipped device conveyed by a second observer, viewing the same presented content and capturing second image data corresponding thereto, the second image data differing from the first due to different vantage points of the first and second observers; determining second identifying data by reference to the captured second image data; by reference to the first identifying data, together with information specific to the first device or first observer, providing a first response to the first device; and by reference to the second identifying data, together with information specific to the second device or second observer, providing a second, different, response to the second device; wherein the first and second devices provide different responses to viewing of the same content presented on the electronic sign. - View Dependent Claims (24)

25. A method involving an electronic sign, viewed by a first observer, comprising the acts:
-
capturing image data corresponding to the electronic sign using a camera-equipped device conveyed by the observer; determining which of plural electronic signs is being observed by the first observer, by reference to the captured image data; and exchanging data between the device and the electronic sign based, at least in part, on said determination. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method for providing contextually-targeted responses to observers of an electronic sign, based on viewing location, the method comprising the acts:
-
obtaining first contextual data relating to a first observer, and second contextual data relating to a second observer; determining first response data associated with the first contextual data, and second response data associated with the second contextual data; obtaining first location data relating to the first observer, and second location data relating to the second observer; receiving image data from an observer'"'"'s device; processing the received image data to estimate a location from which it was captured; and if the estimated location is the first location, returning the first response data to said device. - View Dependent Claims (36, 37, 38)
