In the past few years, science centres have been trying to develop their exhibits by taking hints from “gamification”. By doing so, we can reach visitors emotionally and personally so that the messages we want to convey get imprinted in them through their experiences. But, gaming can easily get into conflict with the science we want to share, online experience with on site visit. How to find the right balance between gaming and scientific knowledge? Between on site and online experience? The matter is rather new, and science centres still experimenting on the matter. Speakers have been facing those issues in different contexts. They will invite you to get hands on their project to find new and innovative solutions that could be useful to anyone willing to get into an exhibit gamification project.
