The Audience Response System (ARS) has two components,

  1. The clicker – a handheld gadget that allows students to participate in lectures, seminars and tutorials, by submitting their responses to questions and viewing the responses as a graph.
  2. A USB receiver – this is usually plugged into a PC at the front of the teaching room, which in turn is connected to a projector.

Turning Point

The University of Bath has opted for the TurningPoint ResponseCard RF (Radio Frequency) ARS. This radio-based option is perfect for small and large groups alike.

With an operating range of 60 metres, it is ideal for a variety of rooms around the university campus.

Unlike the IR (Infra Red) model, the RF model does not require a “line of sight” between the clicker and the receiver.
