Abstract: During a presentation, a question is emitted over a network connection to a plurality of audience members, who utilize a computing device to respond. Client software for the audience members' heterogeneous computing devices may receive questions and upload answers. Answers from the audience are collected and aggregated, including optionally aggregating demographic information associated with each respondent and the answer of the respondent. Real-time analytics are provided to the presenter, which facilitates formulation or selection of further content and/or further questions. The timing of the questions can be synchronized with a content by linking the question to particular portions of the content, by tying the question to a particular slide or frame, by setting a length of time after which the question should be emitted, by offering a question on-demand, or some other method. A website maintains content, questions, user credentials of audience members, responses, and aggregated data, among other aspects.
