Abstract

A method for enhancing a well-being of a small child or baby utilizes at least one TV camera positioned to observe one or more points on the child or an object associated with the child. Signals from the TV camera are outputted to a computer, which analyzes the output signals to determine a position or movement of the child or child associated object. The determined position or movement is then compared to preprogrammed criteria in the computer to determine a correlation or importance, and thereby to provide data to the child.

Claims

1. A computer apparatus comprising:

a laptop housing including an upper portion and a lower portion, the upper portion including a display and the lower portion including a keyboard, the upper portion being movable relative to the lower portion to an open position;

first and second digital cameras supported by the lower portion housing oriented upwardly with and having overlapping fields of view in the region above the keyboard when the upper portion is in the open position, the digital cameras providing respective first and second outputs; and

a processing unit operatively coupled to the first and second outputs, wherein the processing unit is adapted to determine a gesture performed in the overlapping fields of view and is further adapted to correlate the gesture with a computer input function.

2. The computer apparatus of claim 1 wherein the first and second digital cameras are positioned laterally outward of the keyboard.

3. The computer apparatus of claim 1 wherein the processing unit is adapted to compare successive outputs of the first and second cameras to determine the gesture.

4. The computer apparatus of claim 1 wherein the determined gesture includes a pinch gesture.

5. The computer apparatus of claim 1 wherein the determined gesture includes a pointing gesture.

6. The computer apparatus of claim 1 wherein the determined gesture includes a grip gesture.

7. The computer apparatus of claim 1 wherein the upper portion is hinged relative to the lower portion.

8. A computer implemented method comprising:

providing a keyboard, a plurality of keys supported by the keyboard, and first and second digital cameras in fixed relation relative to the plurality of keys, the first and second digital cameras oriented upwardly with overlapping fields of view in the region above the plurality of keys;

detecting a gesture performed in the overlapping fields of view by comparing successive outputs of the first and second digital cameras, the gesture being performed by at least one of a user'"'"'s hand and a user'"'"'s finger; and

correlating the detected gesture with a computer input function, wherein the computer input function is one of a plurality of computer input functions stored in computer readable memory.

9. The method according to claim 8 wherein the detected gesture includes a pinch gesture.

10. The method according to claim 8 wherein the detected gesture includes a pointing gesture.

11. The method according to claim 8 wherein the detected gesture includes a grip gesture.

12. The method according to claim 8 wherein the first and second digital cameras are positioned laterally outward of the plurality of keys.

13. The method according to claim 8 wherein the first and second digital cameras and the plurality of keys are supported by a housing.

14. The method according to claim 13 wherein the housing defines first and second apertures for the first and second digital cameras.

15. A keyboard apparatus for a computer, the keyboard apparatus comprising:

a housing defining an upper surface;

a plurality of keys extending through the housing upper surface; and

first and second digital cameras supported at the housing upper surface and oriented upwardly therefrom with overlapping fields of view in the region above the plurality of keys, the digital cameras providing respective first and second outputs, wherein the first and second outputs are adapted to be coupled to a processing unit operable to determine a gesture performed in the overlapping fields of view.

16. The keyboard apparatus of claim 15 wherein the housing defines first and second apertures for the first and second digital cameras.

17. The keyboard apparatus of claim 16 wherein the housing includes first and second transparent covers overlying the first and second apertures.

18. The keyboard apparatus of claim 15 wherein the detected gesture includes a pinch gesture.

19. The keyboard apparatus of claim 15 wherein the detected gesture includes a pointing gesture.

20. The keyboard apparatus of claim 15 wherein the detected gesture includes a grip gesture.

21. A computer implemented method comprising:

providing first and second cameras in fixed relation relative to each other and including overlapping fields of view, wherein the first and second cameras are coupled to a keyboard and oriented upwardly relative to said keyboard; and

detecting, using the first and second cameras, a gesture performed in the overlapping fields of view, the gesture being performed by at least one of a user'"'"'s hand and a user'"'"'s finger, wherein the first and second cameras are oriented upwardly to observe a gesture performed in a work volume above the first and second cameras.

22. The method according to claim 21 further including providing a light source in fixed relation to the first and second cameras and oriented toward the work volume.

23. The method according to claim 22 wherein the light source includes a light emitting diode.

24. The method according to claim 22 wherein the light source includes a plurality of light emitting diodes.

25. The method according to claim 21 wherein the detected gesture includes at least one of a pinch gesture, a point gesture, a grasp gesture, and a grip gesture.

26. The method according to claim 21 further including determining the pointing direction of one of the user'"'"'s finger using the first and second cameras.

27. The method according to claim 21 further including providing a target positioned on the user that is viewable by the first and second cameras.

28. The method according to claim 21 further including determining the three-dimensional position of a point on the at least one of the user'"'"'s hand and the user'"'"'s finger using the first and second cameras.

29. The method according to claim 21 further including providing a three-dimensional display viewable by the user.

30. The method according to claim 21 wherein:

the first and second cameras are positioned in fixed relation relative to a keyboard; and

the first and second cameras and the keyboard form part of a laptop computer.
