Mindful: A Platform for Large-Scale Affective Field Research

In this work we present Mindful, a platform for defining, configuring, executing and distributing affective experiments to a large scale audience. This type of experiments measure the emotional reaction of participants to media content selected by experimenters. Furthermore, the platform manages profiles of registered users who have agreed to participate in an experiment as well as a data collection and analysis mechanisms. The analyzed data is then used to enrich users' profile and to better understand their emotional behavior. Throughout the paper we describe the platform in details and present a use case of how the platform is being used in practice.
