Abstract

This paper explores the potential for breath control as an interaction medium for gaming. In particular it examines the positioning of breath control within the stack of interface paradigms: As the only control, as a secondary control and as an ancillary or ambient control. It describes a technology developed using specially adapted gas masks to measure breath flow. By describing five simple games (or game modifications), each developed using breath in a somewhat different way, we show some of the possibilities of this unique interface paradigm. Crucially, the paper aims to demonstrate that breathing, though in principle a one dimensional interface medium, is actually a subtle and viable control mechanism that can be used either as a control mechanism in itself, or to enhance a more traditional game interface, ultimately leading to a satisfying and immersive game experience.
