AffectAura: An Intelligent System for Emotional Memory

We present AffectAura, an emotional prosthetic that allows users to reflect on their emotional states over long periods of time. We designed a multimodal sensor set-up for conti-nuous logging of audio, visual, physiological and contex-tual data, a classification scheme for predicting user affec-tive state and an interface for user reflection. The system continuously predicts a user's valence, arousal and engage-ment, and correlates this with information on events, com-munications and data interactions. We evaluate the interface through a user study consisting of six users and over 240 hours of data, and demonstrate the utility of such a reflec-tion tool. We show that users could reason forward and backward in time about their emotional experiences using the interface, and found this useful.
