Deus EM Machina: On-Touch Contextual Functionality for Smart IoT Appliances

Robert Xiao, Gierad Laput, Yang Zhang, Chris Harrison (CHI 2017)

Homes, offices and many other environments will be increasingly saturated with connected, computational appliances, forming the "Internet of Things" (IoT). At present, most of these devices rely on mechanical inputs, webpages, or smartphone apps for control. However, as IoT devices proliferate, these existing interaction methods will become increasingly cumbersome. Will future smart-home owners have to scroll though pages of apps to select and dim their lights? We propose an approach where users simply tap a smartphone to an appliance to discover and rapidly utilize contextual functionality. To achieve this, our prototype smartphone recognizes physical contact with uninstrumented appliances, and summons appliance-specific interfaces. Our user study suggests high accuracy - 98.8% recognition accuracy among 17 appliances.
