hipDisk: Using sound to encourage physical extension, exploring humour in interface design

This article discusses the hipDisk and its development. The hipDisk (see Figure 1) is an interactive sonic system triggered by core-body gesture that highlights and responds to the dynamic relationship between the wearer's hip and torso. The resulting interface turns the body into an instrument by augmenting it with instrumental capabilities. hipDisk sits within a broader research framework that explores how technology can be paired with the body to poeticise experience. In order to discuss this, the process that led to the emergence of hipDisk is elaborated; this is followed by a statement of design goals; a detailed description of the instrument, its construction and behaviour; and an analysis of outcomes and audience response to date. Within this, a discussion of the role of interface, extension, tangibility, and what is afforded by the use of soft as opposed to hard electronics is undertaken. In addition, the limitations and affordances of the hipDisk as an instrument are discussed. Through this article questions are raised about the role of the creative process in the design of interactive, wearable elements and systems, and the value of considering non-functional outcomes such as addressing the inner life of the wearer. I contend that a focus on these issues can provide added value, beyond intended functionality and that, with such a focus, novel yet meaningful applications of technology could be created that poeticise experience and enhance quality of life - for both the wearer and also, possibly, for the observer.
