pptVivo! allows speakers to share their presentation just before they start so attendees can follow the presentation from their mobile devices.
It engages the audience by encouraging participation and feedback through questions and polls and creates a potentially vast audience by encouraging people to tweet and post on Facebook about the talk.
The Problem we observed is that we all have been to conferences where people seemed to pay more attention to their mobile devices than to the live person on the podium. For speakers, it is increasingly difficult to deal with a distracted audience. In addition, attendees do not have the presentation material in advance and such material is generally shared by the speakers at the end of the presentation.
