PowerVote provides audience response systems which allows any participant at a meeting or a conference to answer questions directly, through individual keypads, the results are instantly displayed visually via graphs and charts. PowerVote is a perfect tool for education, training, marketing and communication events. Created in ***7, PowerVote is marketed in France, Great Britain, Germany, Spain and Brasil.

The majority of current audience response systems use wireless hardware. Two primary technologies exist to transmit data from the keypads to the base stations: infrared (IR) and radio frequency (RF). A few companies also offer Web-based software that routes the data over the Internet  (sometimes in a unified system with IR and RF equipment). Cell phone-based systems are also becoming available. The most popular keypad hardware is manufactured by the Fleetwood Group, an audience response hardware producer that partners with several top software producers.

Infrared (IR)

The oldest of these technologies, IR audience response systems are better suited for smaller groups. IR uses the same technology as a TV remote, and is therefore the only one of the four technologies that requires line-of-sight between the keypad and receiver. This works well for a single keypad but can fail due to interference when signals from multiple keypads arrive simultaneously at the receiver. IR systems are typically more affordable than RF systems, but do not provide information back to the keypad.
