"Don't touch the oven"

Abstract

Motion-based touchless interaction empowers users to interact using movements and gestures, and without the burden of physical contact with technology (e.g., data gloves, body markers, or remote controllers). Most motion-based touchless applications are designed for interaction "in-the-large", where users engage with medium or large displays. Our research explores motion-based touchless interaction "in-the- small" that involves only small displays (of the size, for example, of smart phone screens). We have applied this novel paradigm to develop interactive applications for household appliances, discovering that the "in-the-small" feature raises a number of challenging design issues, exemplified in the paper through a case study.
