Surveys help to get the opinion on individual elements of the conference organization e.g. subject matter, venue, meals, lightening and sound system, general organization, parking or integration event. The organizer may prepare such surveys in advance and during the event inform the participants that a survey is available for everyone to fill in. Another option is to remind the participants about the survey using PushNotifications. The replies will be forthcoming with time and on their basis the organizer may draw conclusions.
Surveys may be also used during the session. The speaker during the discussion may send a question to the participants and present the results in a form of a chart on the projector screen.
