"Don't touch the oven": Motion-based Touchless Interaction with Household Appliances

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.
