Inhaling and Exhaling: How Technologies Can Perceptually Extend our Breath Awareness.

Attending to breath is a self-awareness practice that exists within many contemplative and reflective traditions and is recognized for its benefits to well-being. Our current technological landscape embraces a large body of systems that utilize breath data in order to foster self-awareness. This paper seeks to deepen our understanding of the design space of systems that perceptually extend breath awareness. Our contribution is twofold: (1) our analysis reveals how the underlying theoretical frameworks shape the system design and its evaluation, and (2) how system design features support perceptual extension of breath awareness. We review and critically analyze 31 breath-based interactive systems. We identify 4 theoretical frameworks and 3 design strategies for interactive systems that perceptually extend breath awareness. We reflect upon this design space from both a theoretical and system design perspective, and propose future design directions for developing systems that "listen to" breath and perceptually extend it.
