The dials present the available responses to participants on an LED display. Each participant turns the dial's knob to select the desired answer. The system monitors dial movement, so the operator knows when all participants have made their selections. The operator can then poll the dials for data capture and reporting.
The dials communicate wirelessly with the rest of the system, or through wired network cables if necessary, depending on the venue and environment.
Unlike a traditional keypad the Perception Analyzer Dial has a simple knob with the LED display. Turning the dial increases the number displayed.
