A new phenomenon on the Internet is the online audience response. Mentimeter is a web-based tool where you can create online polls. The users can then cast a vote and the result is shown in real time. We want to test the information visualization in Mentimeter and we base our hypothesis, that a better graph design is possible, on the work of Edward Tufte and Stephen Few. Edward Tufte is an emeritus at Yale University, where he held courses in statistical evidence and information design and has created theories about how visual information should be designed. Stephen Few is a known information designer and he has based a lot of his theories on the work of Tufte. We compare Tufte and Fews design principles against the Mentimeter tool with user testing. We can see that Tufte and Fews theories still stand strong when it comes to the comparisment with Mentimeter and that a redesign of their graphs could raise the quality and the user experience of the tool. But Mentimeter is also a tool that functions the way it is supposed to.
