Conferences i/o features a variety of types of polls and behaviors to suit the needs of presenters and collect data and/or encourage participation from the audience.


Multiple Choice

Multiple choice polls are the standard use case for polls, allowing up to 25 predetermined answers for each question. Attendees are presented with a list of the answers and must select at least one, depending on settings, to complete the poll.

Correct Answers

The poll can adopt a quiz behavior by enabling correct answers for the poll.

To do so, select This multiple choice poll has a correct answer, then mark the corresponding choice as the correct answer.

Note: Only one choice can be marked as the correct answer, even if multiple responses are allowed.

Number of User Responses Allowed

Moderators can allow attendees to select more than one choice in the poll by toggling the number of responses allowed to Mark All That Apply. When Just One is selected, attendees can only select and submit a single answer.

Note: Responses allowed cannot be limited to a specific number of responses, e.g. "Answer up to two".

Results Formats

The output of the multiple choice poll can be displayed in one of three ways: a pie chart, a bar chart, or the enhanced bar chart.

Note: Pie chart is not available when This multiple choice poll has a correct answer is enabled.

Sample Bar Chart

Sample Enhanced Bar Chart


  • Pie charts are best used with multiple choice questions containing six or fewer choices that only allow one response, and where the data is best presented as a whole.
  • Bar charts are best used when the multiple choice question allows more than once choice and/or when the data is best presented as a comparison between each choice.

Open Ended / Short Answer

Open ended / short answer polls are useful when collecting qualitative data from attendees. Attendees are presented with a text field to supply a free-form answer to the question to complete the poll.

Multiple Responses

Moderators can switch between allowing attendees to submit one or multiple responses. When Attendees can submit multiple responses is selected, attendees can submit any number of responses while the poll is unlocked. 

Results Formats

The results of an open ended/short answer poll can be displayed as a Word Cloud, a Wordle, a list, or thought bubbles. 

Note: By default, Wordle and Word Cloud results will ignore 1- and 2-character responses, and uses Levenshtein distance to group responses. These settings can be adjusted to be more sensitive, less sensitive, or disabled by contacting Customer Support.

Sample List

Sample Thought Bubbles


  • Word Cloud and Wordle are best for an open-ended poll question that only requires a one-word response. Conferences i/o also recommends prefacing the poll questions with "In one word..." to direct the attendees to respond appropriately.
  • List is best used when not displaying the results in real-time, as a presenter will not be able to scroll up or down to view responses on the Live Content Slides.
  • Thought Bubbles are best used in an open-ended poll question that requires a two or more word response.

Numerical Average

The numerical average poll type uses two whole-number anchor points in order to get a rating from attendees that is averaged across all responses. Attendees can only submit one response, and are presented with a list of choices to select from to complete the poll.


Note: If there are more than 10 possible responses, attendees are instead presented with a text field to input their choice. Attendees must still submit whole numbers as the response.

The brainstorming poll type allows moderators to crowdsource ideas from the audience. Attendees are presented with an option to add a new idea and thumbs-up any other ideas they like. Ideas are sorted by the most thumbs-up to the moderator, but are randomized to the attendee to prevent bias. Moderators can delete responses on the fly from the moderator view and can see the number of thumbs-ups each idea has received.
