Augmented Foot - A Comprehensive Survey of Augmented Foot Interfaces.

Augmented foot interfaces have been studied since the beginning of wearable computers. The worlds’ first wearable computer was an instrumented shoe that consisted of a toe operated switch with a wireless module. Since then, academic research and commercial products on augmented foot interfaces are booming with novel interfaces every year. This paper surveys the body of work on augmented foot interfaces and shows the current trends and guidelines for future augmented foot interfaces. We contribute a classification of over 100 academic papers and commercially-available products. We discuss the integration of augmented foot interfaces, interaction schemes and application domains. Finally, we contribute a set of design considerations to scaffold future research of augmented foot interfaces based on the classification and inspired by the surveyed work.
