This article in Washington Technology describes a smart conference room developed by researchers at the National Institute of Standards and Technology (NIST). The Institute's Smart Space Laboratory is developing work environments that use a variety of technologies, including embedded computers, information appliances, and multi-modal sensors, to make performing tasks more efficient by offering unprecedented levels of access to information and assistance from computers. The smart conference room is equipped with arrays of microphones that serve not only for speech recognition, i.e. to make automatic transcripts of a meeting, but also for tracking people as they move around. The microphones detect the location of each voice in the conference room and pass it to one of five video cameras, which feed into a data acquisition system based on a 14-node Linux cluster. The cluster is configured with Open Source middleware called the Smart Flow System, which correlates the input from audio and video channels using voice- and face-recognition techniques (see schematic). The ultimate goal is for the system to follow what a conversation is about, so that it can go out and get services assisting with the problem being solved in the meeting.
