Abstract
An audience participation system and method utilizing wireless transmission is provided. The system includes a plurality of modules in the possession of an audience, each module having a keypad or other means which is activated by a member of the audience in order for the audience to respond to a question posed by the speaker during his presentation. After the speaker poses a question, the audience responds by supplying information through a physical input into the module. The module then encodes the information provided into an encoded electrical pattern. This encoded electrical pattern is modulated into an electromagnetic signal which is then electromagnetically transmitted. A base station has a receiver for capturing the electromagnetic signal which is then demodulated into the encoded electrical pattern originally transmitted. The data are retrieved and collected, and then statistically analyzed according to the wishes of the speaker and displayed to present a statistical analysis of the combined audience response to the question posed.
