Dialsmith had the pleasure of providing audience feedback at TED2011. Audience members used Perception Analyzer dials to to confidentially give continuous, real-time feedback TED. Each Talk and video was evaluated, resulting in rich data for TED staff to use in their on-going quest to enhance the TED experience, both live and online.
This method of continuous, moment-to-moment data collection is the same as used by CNN and MSNBC for presidential debates and State of the Union speeches, as well as television networks for TV pilot testing. It is also used extensively for advertising research, presentation evaluation, and more.
