Abstract

In certain implementations consistent with the present invention, a method for monitoring a television system viewer'"'"'s status involves monitoring a field of view encompassing a viewer environment using a camera sensitive to light in the infrared (IR) spectrum; identifying a pair of bright spots in the IR spectrum that are spaced by a spacing consistent with spacing of a pair of human eyes; monitoring at least one characteristic of the spots to ascertain a status of a television system viewer; and at the television system, taking an action that affects an operational characteristic of the television system on the basis of the ascertained status of the television system viewer. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Claims

1. A method for monitoring a television system viewer'"'"'s status, comprising:

monitoring a field of view encompassing a viewer environment using a camera sensitive to light in the infrared (IR) spectrum;

identifying a pair of bright spots in the IR spectrum that are spaced by a spacing consistent with spacing of a pair of human eyes;

monitoring at least one characteristic of the spots to ascertain a status of a television system viewer; and

at the television system, taking an action that affects an operational characteristic of the television system on the basis of the ascertained status of the television system viewer.

2. The method according to claim 1, wherein the at least one characteristic comprises at least one of fading characteristics, blinking characteristics and disappearing characteristics.

3. The method according to claim 1, wherein the at least one characteristic comprises an orientation of the bright spots.

4. The method according to claim 1, further comprising illuminating the field of view captured by the camera with light in the infrared spectrum.

5. The method according to claim 1, wherein the spacing encompasses at least a portion of the range of 40 to 70 mm.

6. The method according to claim 5, wherein the spacing is interpreted as an indication of range of the viewer from the camera.

7. The method according to claim 1, wherein the at least one characteristic is interpreted as an indication that the viewer is asleep, and wherein the action comprises fading an audio volume of the television system.

8. The method according to claim 1, wherein the at least one characteristic is interpreted as an indication that the viewer is asleep, and wherein the action comprises fading reducing a video brightness of the television system.

9. The method according to claim 1, wherein the at least one characteristic is interpreted as an indication that the viewer is asleep, and wherein the action comprises placing the television system in a “

standby”

, “

sleep”

or “

off”

mode;

or storing a time stamp associated with the program being viewed.

10. The method according to claim 1, wherein the at least one characteristic comprises a tilt angle of the spots.

11. The method according to claim 10, wherein the action comprises adjusting an angle of tilt of an image displayed on the television system.

12. The method according to claim 1, wherein the action comprises starting, stopping or pausing a recording process;

or storing a time stamp associated with the program being displayed.

13. A tangible computer readable electronic storage medium storing instructions which, when executed on one or more programmed processors, carry out a method according to claim 1.

14. A method for monitoring a television system viewer'"'"'s status, comprising:

monitoring a field of view encompassing a viewer environment using a camera sensitive to light in the infrared (IR) spectrum;

illuminating the field of view captured by the camera with light in the infrared spectrum;

identifying a pair of bright spots in the IR spectrum that are spaced by a spacing consistent with spacing of a pair of human eyes, wherein the spacing encompasses at least a portion of the range of 40 to 70 mm;

monitoring at least one characteristic of the spots to ascertain a status of a television system viewer, wherein the at least one characteristic comprises at least one of fading characteristics, blinking characteristics, disappearing characteristics and orientation characteristics; and

at the television system, taking an action that affects an operational characteristic of the television system on the basis of the ascertained status of the television system viewer, wherein the at least one characteristic is interpreted as an indication that the viewer is asleep, and wherein the action comprises fading an audio volume of the television system one characteristic is interpreted as an indication that the viewer is asleep, and wherein the action further comprises fading reducing a video brightness of the television system and further comprising placing the television system in a “

standby”

, “

sleep”

or “

off”

mode when the audio volume and video brightness are reduced.

15. The method according to claim 14, wherein the spacing is interpreted as an indication of range of the viewer from the camera.

16. The method according to claim 14, wherein the at least one characteristic comprises a tilt angle of the spots.

17. The method according to claim 16, wherein the action comprises adjusting an angle of tilt of an image displayed on the television system.

18. The method according to claim 14, wherein the action comprises starting, stopping or pausing a recording process;

or storing a time stamp associated with the program being displayed.

26. The television system according to claim 17, wherein the at least one characteristic comprises a tilt angle of the spots and wherein the action comprises adjusting an angle of tilt of an image displayed on the television system.

19. A television system apparatus that monitors a television system viewer'"'"'s status, comprising:

a camera that monitors a field of view in the infrared (IR) spectrum that encompasses a viewer environment;

one or more processors that identifies a pair of bright spots in the field of view that are spaced by a spacing consistent with spacing of a pair of human eyes;

the one or more processors monitoring at least one characteristic of the spots to ascertain a status of a television system viewer; and

the one or more processors taking an action that affects an operational characteristic of the television system on the basis of the ascertained status of the television system viewer.

20. The television system according to claim 19, wherein the at least one characteristic comprises at least one of fading characteristics, blinking characteristics and disappearing characteristics.

21. The television system according to claim 19, wherein the at least one characteristic comprises an orientation of the bright spots.

22. The television system according to claim 19, further comprising a source of IR light illuminating the field of view captured by the camera.

23. The television system according to claim 19, wherein the spacing encompasses at least a portion of the range of 40 to 70 mm.

24. The television system according to claim 19, wherein the at least one characteristic is interpreted as an indication that the viewer is asleep.

25. The television system according to claim 24, and wherein the action comprises at least one of fading an audio volume of the television system, fading reducing a video brightness of the television system, and placing the television system in a “

standby”

, “

sleep”

or “

off”

mode.

27. The television system according to claim 19, wherein the action comprises starting, stopping or pausing a recording process;

or storing a time stamp associated with the program being displayed.
