We launched Xorro-Q last September to satisfy a burgeoning demand within our K-12 school user community for a browser-based student response solution able to leverage the explosion in "BYOD" programs. We very quickly unearthed strong interest from several other groups:
What these groups all have in common is they need very simple enrollment of participants, combined with the ability to manage the real-time participation process very easily. and with no disruption whatsoever to the presentation content.
Xorro-Q's Launcher is designed for exactly that purpose: Enabling a presenter, teacher or coach to deliver an "instant" (or pre-prepared) question to a group, receive the responses, and integrate these into the presentation without ever taking the focus off the topic.
