Illuminating research

MIT: These days, in newer buildings it’s often hard even to find a plain old-fashioned light switch. Often, the only controls are automatic motion-detector switches that turn off lights when people have left a room — or when they sit too still — or else daunting control panels with arrays of sliders and buttons.
