Abstract

The device consists of measuring aspects of human activity or emotion and then communicating that information to an adjustable lighting device or electronic display (as part of a phone, tablet, computer etc) such that the color temperature (or luminance) of the display or lamp is adjusted to match the mood of the user e.g. warmer in the evening close to the end of the day, and cooler in the morning for productivity.
