Abstract: A computer-implemented method of lighting control is disclosed. The method includes identifying a group of people according to a relationship between or among the people that indicates the people are likely to regularly reside in a common location, determining a goal for the group of people for aligning circadian cycles of people in the group of people, determining a time and manner for altering ambient light at the common location in a manner to achieve the determined goal; and generating control signals to cause ambient lighting appliances at the common location to alter their performance according to the determined time and manner to achieve the determined goal.

Abstract: The invention provides a system for dynamically adjusting displays, particularly displays associated with electronic devices such as computers. The system provides for manual and automatic adjustment of displays, and adjustment of signals to displays, where such adjustments are made in consideration of the environment in which the display is viewed. In one embodiment the inventive system uses at least one sensor to monitor some environment condition and adjusts display color relative to sensor input. In a preferred embodiment, the system provides automatic display adjustments so that display colors adjust according to time of day, becoming warmer after dark, to simulate indoor lighting, and cooler (“sunlight-like”) during the day, to match sunlight as perceived by a human viewer. Advantages of the invention include reduction of eye-strain as well as task-specific accommodations.

Abstract: A computer-implemented method and includes identifying a change to be made in a brightness level of the light-generating appliance, the identifying of the change being effected by an input external to the light-generating appliance; determining, with a component of the light-generating appliance and in response to identifying the change to be made in the brightness level, a level of change to be made in a nonbrightness-related lighting output parameter of the light-generating appliance, to maintain a level of user stimulating light for a user visually exposed to the light-generating appliance, the level being equal as before the change in brightness level is made and after the change in brightness level is made; and changing the brightness level of the light-generating appliance according to the identified change in the brightness level, and changing the nonbrightness-related lighting output parameter based on the determined level of change to be made in the nonbrightness-related lighting output parameter.
