Narrowcasting from public displays, and related methods
First Claim
1. A method involving an electronic sign, viewed by a first observer, the method comprising the acts:
- obtaining position information about the first observer by reference to information from a camera;
defining a first digital watermark signal that takes into account the position information, and conveys a payload established in accordance with contextual data relating to the first observer;
encoding image data in accordance with said first digital watermark signal; and
presenting the encoded image data on the electronic sign;
wherein said defining is performed by a hardware processor configured to perform such act, and includes at least one of the following;
(a) tailoring a scale of the first digital watermark signal in accordance with a viewing distance;
or(b) tailoring a projection of the first digital watermark signal in accordance with a viewing angle.

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.
