Research indicates that there is a potential for persuasive technologies to be used as a means for increasing physical activity. In this exploratory work, we developed a mobile web application to gather movement data to explore the potential of a health tool in the context of a dance floor to promote physical activity. We wanted to explore if the mobile application in combination with the context and mechanisms seen in other health applications could drive physical activity. In total, 208 participants generated 20,279 data points through the mobile application on the dance floor. The result from this work points out that the concept should be further investigated in more studies.
