Additional software options depend upon how advanced or stylized the functions need to be for your intended purpose, be it training, videoconferencing, research or another use. For instance, Option Technologies' OptionFinder 5.2 software supports various decision-making models and creates demographic tabulations for research purposes. Some packages, such as Meridia Interactive's RSVP-Net software, support multisite meeting and conferencing capabilities, in which participants in various cities join via satellite to respond to issues. A.R.S. offers PowerPoll software, which runs like PowerPoint, for simple uses requiring general feedback, and Inquiry, an advanced application for full-service meetings, testing, filtering and team gaming. The information is scalable to any communications network, making it capable of simultaneously reaching participants in keypad-equipped classrooms.
Wired systems do have some advantages, though.
For instance, they are less expensive and still make sense for permanent installations. Many game shows and televised interactive events also use wired systems to prevent participants from stealing the units and to avoid the problem of a wireless system's radio frequencies interfering with broadcast equipment. Organizations that conduct frequent elections also commonly use wired systems because they can still process information to a computer faster than wireless systems can. Indeed, A.R.S. reports that wired systems constitute only 10 percent of its business. The process of setting up wired systems also requires considerably more people, time and maintenance.
