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.
