We describe the design process taken and prototype developed for a system supporting audience voting at the Summer Olympics. In our examination of issues related to the expression and capture of audience votes, we utilized informal focus groups, interviews with experts, and user studies comparing voting formats. Our proposed solution involves displaying results on large screens. This provides the context for visual audience interaction through the use of ranking booklets. The audience input is determined through image analysis of the audience.
