The Group Challenge is a quiz game for use at trade shows. It runs on a large multi-touch screen, allowing users to stand in front of it to interact while still having room for spectators to view the screen. It allows two show attendees to join the game and compete against each other by answering questions about Parkinson’s disease as well as playing a ball popping mini-game. After the game, the players with the highest score are shown on a leaderboard. Other variants of this game have also been built, including versions supporting 3-5 players as well as versions with content pertaining to Seizures, MS, and various marketing surveys. The game can also be adapted to use iPads or Windows tablets as a ‘game controller’ for users to read the questions and enter their answers. While scanning into and playing the game, lead and survey data is captured from the attendees and supplied as a post-show report.
