This paper presents the SWAY prototype that encourages people to explore aspects around balance and posture in a playful way. The prototype senses small movements and shifts in posture using a Kinect sensor, and translates these movements to the tilting of a platform holding a set of marbles, and to haptic feedback in the form of vibrations. The prototype provides an interactive experience focusing on building body awareness with a particular focus on balance and posture. The design inquiry provided new insights with respect to reinforcement of bodily experiences and how different modalities affect the guiding of attention.
