Challenges, feedback & notifications: empirical explorations to inform the design of interfaces to motivate and encourage long-term personal informatics use.

ABSTRACTIn our research group, we are currently carrying out several empirical research studies to inform the design of future personal informatics (PI) systems. These studies include projects investigating the use of gamification elements to encourage engagement based on a user's personality type, varying levels of feedback during day-to-day PI use, and categorizing and evaluating the suitability of dispatching PI notifications across a wide variety of wearable devices and using different feedback modalities. We provide an overview of these projects and suggest ways that our early results might contribute to the discussion of next-generation systems at the UbiComp 2015 QS workshop.
