As smart homes become more widespread, the need for more natural forms of interaction in the home also increases. On the one hand, forcing a user to go to a central home controller at every required change does not make sense. On the other hand, having a different controller for each device is also quite overwhelming. Object-Specific Interfaces (OSIs) allow an interface customized to an object of interest to show up on a mobile device when in close proximity to it. The interface can be passive, thus showing a manual or information, or interactive and so would allow for device monitoring and controlling.
