I recently had the opportunity at two separate conferences to use audience response pads and virtual pads at the same time for a live audience. I gave the audience a link to the virtual keypad for my session while other attendees used an issued wireless keypad. For the audience members who had a remote device, (i.e. - a smartphone, iPhone, iPad, tablet or a laptop computer), they simply visited the link and was able to participate via a virtual keypad. Since I didn't have enough audience response keypads for the entire classroom, I found that the use of remote PING Virtual Keypads enabled everyone to participate. It also kept them from texting during my sessions! For more information on using virtual keypads in your next session, visit the PING webpage here: http://c3softworks.com/products/online/ping
