An acronym that means audience response system, which is a system that allows a group of people to interact with each other and a presenter by voting on a topic or answering a question. Depending on the audience response solution chosen, each person has a device with which selections can be made. In a hardware solution, each remote communicates with a computer via receivers located around the room or via a single receiver connected to the presenter’s computer using a USB connector. In a software solution, each device communicates with the question via SMS or the Internet. After a specific amount of time has passed, the ARS ends the polling and the results are instantly made available to the participants displayed on the projector but can also be viewed in a web browser.
