Abstract

A system for influencing a state of a user includes a display with a light source for emitting light influencing the state of the user. A light controller selectively controls the emission of the light including at least one of; (1) the spectrum of the light; (2) the duration of the light; 3) the distribution of the light; (4) the intensity of the light; and (5) the timing of the light. An analysis engine capable of providing a signal to the light controller indicating a desired emission of the light based upon selectively illuminating one or more of a plurality of different blue light sources, each of which having a different peak spectrum.

Claims

1. A system for influencing a state of a user, said system comprising:

(a) a display with a light source for emitting light suitable to use an input image to render an output image on said display, and to influence the state of the user;

(b) a light controller selectively controlling said emission of said light to render said output image;

(c) an analysis engine indicating a desired emission of said light characterized by selective illumination of a plurality of blue light sources having different respective spectral characteristics, wherein a first one of said blue light sources emits primarily blue light having a peak spectrum at a first wavelength, wherein a second one of said blue light sources emits primarily blue light having a peak spectrum at a second wavelength so as to increase melatonin levels in a viewer, wherein said first wavelength is different than said second wavelength, and where said analysis engine analyzes said input image to determine a relative mixture of light emitted by said first one of said blue light sources and light emitted by said second one of said blue light sources, with respect to each other, to produce said output image, where said relative mixture varies spatially over the output image and where the analysis of said input image is used by said analysis engine to determine a spatial variance of said relative mixture such that more light from said first one of said blue light sources is added to local areas of said image prioritized by said analysis engine for image quality.

2. The system of claim 1 wherein said different blue light sources are spatially distributed across a majority of said light source.

3. The system of claim 1 wherein one of said blue light sources is selected for illumination to reduce melatonin production in a viewer.

4. The system of claim 1 wherein one of said blue light sources is selected to increase melatonin production in a viewer.

5. The system of claim 1 wherein said mixture of said plurality of different blue light sources is selected based upon a desired change in melatonin production in a viewer.

6. The system of claim 1 wherein said light controller is modulated based upon at least one of (a) a profile of said user and (b) an identification of a particular said user.

7. The system of claim 6 further comprising said analysis engine obtaining information from said profile from a mobile device.

8. The system of claim 1 further comprising said analysis engine obtaining information regarding a time of day.

9. The system of claim 1 further comprising said analysis engine obtaining information regarding a physical location of said user.

10. The system of claim 1 further comprising said analysis engine obtaining information regarding environmental factors of said user.

11. The system of claim 1 further comprising said analysis engine obtaining information regarding social networking.

12. The system of claim 1 further comprising said analysis engine obtaining information regarding medical information.

13. The system of claim 1 further comprising said analysis engine obtaining information from a light sensor associated with said user.

14. The system of claim 1 further comprising said analysis engine obtaining information from a physiological sensor associated with said user.

15. The system of claim 1 further comprising limiting exposure to said light based upon a safety factor.
