Illuminac

1. Berkeley Institute of Design Illuminac Simultaneous Naming and Configuration for Workspace Lighting Control • Motivation • The number of electronic devices in our environment is ever increasing. While this brings greater flexibility and control, configuring each individual devices becomes ever more tedious. For example, to watch a movie, one might: • Dim the lights, • Turn speaker volume to medium, • Close the blinds, • Turn the television on • Turn the DVD player Simultaneous Naming and Configuration In order to match the user’s mental model, the system should allow the user to use an intuitive name for the activity rather than the configuration of each individual device. These names and configurations must be customized for the individual users in order to support an intuitive interface. Thus the system must simultaneously learn the names of the configurations and the configurations of devices. We use non-negative matrix factorization to in our learning algorithm because it allows factors to overlap, which is important for our problem. User-Extensible Speech Interface Illuminac is a user-extensible speech interface designed and deployed in a workspace with six graded-awareness cubicles and an open multiuse space. The workspace has 79 individually controllable lights (devices). Users train the system on their customized commands and configurations of lights or lighting scenes. “Can I get the meeting lights on please?” To use Iluminac, simply speak a command into one of the microphones distributed throughout the room. “Please turn Mike’s desk lights up.” Evaluation We deployed Illuminac with ten occupants of the lab for one week. The system ran with live speech recognition and live training mode. Participants recorded the accuracy of the system response after each use. To add a customized command and configuration, use the web-based training interface.
