Method and apparatus for audience participation by electronic imaging
First Claim
1. A method for collecting data from at least one person, comprising the steps of:
- providing each person with a radiation source capable of defining at least two states;
scanning all the radiation sources with a detector thereby determining the state of each scanned source; and
aggregating the determined states into data.

Abstract
An audience response system in which each audience member is provided with a reflective device which is, for example, green on one side and red on the other side. Light from a floodlight is reflected from the reflectors and imaged by a conventional video camera. A computer receives the digitized and processed image, forms a map of the audience, and distinguishes the red from the green reflections. This data is then used by the computer to project an image onto a screen visible to the audience, the image being controlled by the red or green image reflections. The audience thus jointly controls the screen image, for instance for purposes of voting or playing a game.

12. A method for collecting data from at least one person, comprising the steps of:
-
providing each person with a retroreflector capable of defining at least two states;
each state characterized by a different color reflection;providing a source of light substantially coaxially mounted with a video camera; scanning the locations occupied by each person with the video camera, thereby determining the state defined by each retroreflector; and aggregating the state of each scanned retroreflector into data.
