Nothing rivals an electronic group response system for stimulating participation and measuring comprehension in a variety of environments.
Wireless systems are much easier to setup and, as necessary, move from location to location.
Additionally, radio communications are inherently more reliable since these devices do not depend on a maze of cables and connectors. Setting up meeting areas with wired products means installing and securing a multitude of cables, and infrared systems generally require repeaters and concentrators. It is possible to walk about the room, transmit through or around tables, and move the pad about a work area while remaining linked to the presentation at all times. Multiple sites may be teleconnected to extend interaction to several thousands of networked participants. There are, of course, many more advantages to using wireless response systems.
