Nowadays, people have access to increasing amounts of data. New wearables, mobile devices and Internet-of-Things sensors are enabling us to monitor our environment, understand our social connections, and track our personal health. However, most of these systems communicate data through classic information visualization that were originally designed for domain experts.
There is a need to consider novel interfaces and devices that enable end-users to visualize, use and appropriate data collected by such new tracking devices. In this work, we investigate how a physical artifact could support seamless integration of personal activity data in everyday life. We introduce LOOP, a physical artifact that changes its shape according to the activity data of the owner, providing an abstract visualization. We elaborate on the design of LOOP and present a one-week field study which shows that LOOP elicited reflection on activity data and supported the different goals people can have with this technology.
