The Affective Health system is a mobile lifestyle application that aims to empower people to reflect on their lives and lifestyles. The system logs a mixture of biosensor-data and other contextually oriented data and transforms these to a colorful, animated expression on their mobiles. It is intended to create a mirror and thereby empower users to see activity patterns and relate these to their experiences of stress. People's different cultural backgrounds and their different physiological and psychological composition give them different perceptions and associations of time. We explore the time dimension of our system through working through a set of different designs that organize events as time going linearly forward, in a circular movement or relating to geographical places. Here we discuss the process of designing a mobile interface for presenting temporal data in a way that allows multiple and subjective interpretation.
