Narrowcasting From Public Displays, and Related Methods
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 comprising the acts:
receiving input image data having an undistorted aspect;
encoding the input image data in accordance with a steganographic digital watermark pattern; and
presenting the encoded image data on a display screen;
wherein the steganographic digital watermark pattern has a distorted aspect relative to the input image data.
22 . A method comprising the acts:
capturing imagery using a camera associated with a first system;
detecting features in the captured imagery; and
identifying, to a second system, augmented reality graphical data associated with the detected features, wherein the second system is different than the first.
23 . The method of claim 22 in which the first system comprises an electronic sign system, and the second system comprises a user's cell phone.
24 . The method of claim 22 that further includes presenting augmented reality graphical data on the second system, wherein the presented data is a tailored in accordance with one or more demographic attributes of user of the second system.
25 . An article of manufacture including a computer-readable medium having instructions stored thereon that, if executed by a computing device, cause the computing device to perform operations comprising:
receive imagery captured using a camera associated with a first system;
detect features in the captured imagery; and
identify, to a second system, augmented reality graphical data associated with the detected features, wherein the second system is different than the first.
