There has been a recent increase in breathing as an activity within HCI; however, breathing as the source of voice has not been explored. This thesis explores how ADA (air-driven actuator), a haptic wearable garment, may be used by singers to connect with their breath. Primarily through first-person engagement with vocal training and first-person evaluation of ADA’s capability to support vocal practice, the thesis addresses how the garment functionally and experientially supports singers’ movements. Thematic analysis results in two main lines of functional use (demonstrations, and prompts), and engagement with the garment in these two usages builds three conceptualizations of how ADA can align with a singer’s breath (through posture adjustments, inhalation as expansion, and inhalation as tension). Further thematic analysis shows how users characterize experiences with ADA as distinguished by anticipation or layering, offering insight into what experimental qualities underlie the functional use of ADA. The thesis highlights implications for future generative work in the breathing design space, offering tension-release as a breath representation, and a suggestion to explore exhalation duration as a breath parameter through the prolongations of exhalations in singing. Furthermore, it highlights layering as a quality that may be of relevance to further development of ADA, or other experience-oriented technology that aims to support movement practice.
