Design semantics of connections in a smart home environment

48 Abstract As the environments in which we live become more intelligent— through more computational power, embedded sensors and network connections between the devices that reside in the environment—there is a risk of leaving its users clueless about what is going on. User interaction changes from interaction with a single device into interaction with a larger system— an ecology of things. Physical things are becoming mediators between the physical world and the digital, invisible world that is inside and behind them. The work we present in this article is part of ongoing academic research on using explicit design semantics to convey abstracted models of connections between devices in a smart home environment. This enables users to understand and construct meaningful mental models of the smart environment and interact with it accordingly. We illustrate our findings by presenting a demonstrator that gives users physical control over invisible, wireless connections between devices in a home entertainment scenario.
