Abstract

A system for influencing a state of a user including a light source for emitting light influencing the state of the user and a light controller selectively controlling the emission of the light. The emission may include at least one of, the spectrum of said light; the duration of said light; the distribution of said light; the intensity of said light; and the timing of said light. The analysis engine provides a signal to the light controller indicating a desired emission of the light.

First claim

We claim:

1. A system for influencing a state of a user comprising:
(a) a light source for emitting light influencing the state of the user;
(b) a light controller selectively controlling said emission of said light from said light source, including controlling at least one of:
(1) the spectrum of said light from said light source where said light controller selectively changes said spectrum of said light from a first non-zero range to a second different non-zero range, and;
(2) the duration of said light emission from said light source where said light controller selectively changes said duration of said light, and;
(3) the spatial distribution of said light from said light source where said light controller selectively changes said spatial distribution of said light; and
(4) the timing of said light emission from said light source where said light controller selectively changes said timing of said light; and
(5) the brightness of said light from said light source where said light controller selectively changes said brightness by modifying the brightness of a plurality of sources of light from said light source;

(c) an analysis engine providing a signal to said light controller indicating a desired emission of said light; where
(d) said light controller further automatically modifies without user intervention said emission of said light from said light source based upon said analysis engine, and using feedback received by said light controller and from selective ones of a plurality of light sensors indicative of perceived light provided to the eyes of a user, said feedback based on said system automatically selecting a subset of said plurality of light sensors as being indicative of said perceived light, said subset less than all of said plurality of light sensors.

2. The system of claim 1 further comprising said analysis engine obtaining information from a profile of said user and using said information from said profile of said user to modify said signal to said light controller indicating said desired emission of said light.

3. The system of claim 1 further comprising said analysis engine obtaining information regarding a time of day and using said information regarding said time of day to modify said signal to said light controller indicating said desired emission of said light.

4. The system of claim 1 further comprising said analysis engine obtaining information regarding a physical location of said user and using said information regarding said physical location of said user to select said subset.

5. The system of claim 1 further comprising said analysis engine obtaining information regarding environmental factors of said user and using said information regarding said environmental factors of said user to modify said signal to said light controller indicating said desired emission of said light.

6. The system of claim 1 further comprising said analysis engine obtaining information using a statistical parameter measured from a plurality of different individuals within a social network of said user and using said information to modify said signal to said light controller indicating said desired emission of said light.

7. The system of claim 1 further comprising said analysis engine obtaining information regarding medical information and using said information regarding said medical information to modify said signal to said light controller indicating said desired emission of said light.

8. The system of claim 1 where at least one of said plurality of light sensors is adapted to remain in proximity to a user's retina when selected by said system, while said user moves.

9. The system of claim 1 further comprising said analysis engine obtaining information from a physiological sensor associated with said user and using said information regarding said physiological sensor associated with said user to modify said signal to said light controller indicating said desired emission of said light.

10. The system of claim 1 further comprising:
(a) a sensor capable of detecting a physiological parameter of said user;
(b) a light sensor for sensing light; where
(c) said sensor and said light sensor providing a signal indicative of said physical parameters and said sensed light to said analysis engine.

11. The system of claim 10 further comprising said analysis engine obtaining information from a profile of said user and using said information from said profile of said user to modify said signal to said light controller indicating said desired emission of said light.

12. The system of claim 10 further comprising said analysis engine obtaining information regarding a time of day and using said information regarding said time of day to modify said signal to said light controller indicating said desired emission of said light.

13. The system of claim 10 further comprising said analysis engine obtaining information regarding a physical location of said user and using said information regarding said physical location of said user to modify said signal to said light controller indicating said desired emission of said light.

14. The system of claim 10 further comprising said analysis engine obtaining information regarding environmental factors of said user and using said information regarding said environmental factors of said user to modify said signal to said light controller indicating said desired emission of said light.

15. The system of claim 10 further comprising said analysis engine obtaining information from a social network of said user and using said information to modify said signal to said light controller indicating said desired emission of said light.

16. The system of claim 10 further comprising said analysis engine obtaining information regarding medical information and using said information regarding said medical information to modify said signal to said light controller indicating said desired emission of said light.

17. The system of claim 10 wherein said a light controller selectively controls said distribution of said light based upon said signal from said analysis engine.
