Abstract
A wireless audience response system can have a host unit, presenter device, and a plurality of audience response units with keypads, with the host unit being communicatively coupled to a computer. In some embodiments, the audience response units can be used to execute functions using application programs within the computer remotely. Also, in other embodiments, the audience response units track delay times required for transmitting input data, with the delay times being usable in comparing response times at the host unit.
