Audience response communication system

摘要

The present invention is directed to an audience response communication system comprising a base unit and a plurality of remote input devices. The audience response and communication system lowers the risk of undelivered data transmissions by enabling the remote input devices to sequentially transmit responses via multiple transmission channels until a vote acknowledgement message is received, or a predetermined number of attempts is made.
