LOOP is a physical artifact that changes its shape according to the activity data of the owner, providing an abstract visualization. The artifact consists of eight rings, of which seven represent weekdays from small to large, and the outermost ring represents the step goal. When the owner is active, the ring representing the current weekday moves upwards and positions itself in relation to the step goal ring. LOOP was used to investigate how an alternative approach to representing personal activity data can support self-tracking activities in everyday life.
