GENIE: Photo-Based Interface for Many Heterogeneous LED Lamps

Abstract

We present an interface to allow for easy selection and creative control of color changing lamp fixtures in the home, using the analogy of taking a snapshot to select them. The user is presented with a GUI on their mobile phone to control light attributes such as color, brightness, and scheduling and is provided a means to specify a group of lights to be controlled at once. This is achieved using an IR filter switcher on the phone to capture IR blobs pulsating from inside the lamps and uses a central server to communicate between the two. The system can operate under normal, indoor lighting conditions and is concealed inside the lamps without any need to place fiducials or other obscuring means of identification in the environment.
