Design aspects in a mobile biofeedback system - developmentof a new interface concept usingdesign qualities

Abstract: It has been established that long term stress can lead to chronic illness of cardiac disease and vascular disorder. In the way people live their lives today they are surrounded by stress and they contribute to the stressful society when they constantly chase the time. The Mobile Life Centre explores how the system Aective Health can get people to reect up on their stress levels and connect that to their everyday activities by using bio sensors and a mobile phone. The bio sensor data visualization in the interface of the system is today tied to time. Since time is perceived dierently from person to person that is something that has caused problems for the design team of Aective Health. This thesis examines how dierent representations of time in user interfaces can be used to mediate the design qualities of subjective time, aliveness and uency in the Aective Health system. As a result from investigating the time aspect and how time can be visualized in a subjective way a suggestion for a design solution was developed.
