Abstract

A telepresence system enhances the perception of presence of a remote person involved in a video conference. The system preferably has a two-way mirror, which is between the observer and the display device, positioned at an angle to reflect a backdrop surface. The backdrop surface may or may not appear superimposed in a position behind the image of a person from the remote location. The system preferably minimizes image distortion via an optical path for the camera line of sight that is substantially longer than the physical distance between the user and the camera. The system may be asymmetrical, in that one camera is on axis with the user'"'"'s line of sight while the other camera is off axis with the user'"'"'s line of sight.

Claims

1. A telepresence system capable of allowing a user to communicate with a person using a communications system, the telepresence system comprising:

an image display device having an image area, said image area being in an image plane positioned for viewing from an observation zone;

a two-way mirror between said observation zone and said image display device, said two-way mirror being in a mirror plane, wherein said mirror plane and said image plane form an angle;

a backdrop adjacent to said two-way mirror;

a camera proximate said backdrop such that said camera views said observation zone as a reflection off said two-way mirror; and

a light-absorbing panel adjacent said two-way mirror opposite said camera and located in a view of said camera through said two-way mirror as said camera is aligned to view said reflection of said observation zone off said two-way mirror.

2. The telepresence system of claim 1, wherein said backdrop is a light absorbing black surface.

3. The telepresence system of claim 1, wherein said backdrop is positioned so that a reflection of said backdrop in said two-way mirror appears within a same plane as said image area when viewed from said observation zone.

4. The telepresence system of claim 1, wherein a left edge and a right edge of said backdrop is reflected in said two-way mirror and aligns with a left edge and a right edge, respectively, of said image area when viewed from said observation zone.

5. The telepresence system of claim 1 wherein a front edge of said backdrop is reflected in said two-way mirror and aligns with a top edge of said image area when viewed from said observation zone.

6. The telepresence system of claim 1, wherein said image display device is a flat panel monitor and an enclosure surrounding said image area is a bezel of said flat panel monitor.

7. The telepresence system of claim 1, wherein said camera views said observation zone as said reflection off said two-way mirror through an aperture in said backdrop.

8. The telepresence system of claim 1, wherein a reflective mirror is proximate an aperture in said backdrop in said view of said camera so that said camera views said observation zone as said reflection off said two-way mirror and a reflection off said reflective mirror.

9. The telepresence system of claim 1, wherein said camera view is aligned with a line of sight of a user when said user looks at eyes of an image of a person displayed on said image display device.

10. The telepresence system of claim 1, wherein lights are positioned behind said image display device to illuminate a wall or a panel positioned behind said image display device.

13. The telepresence system of claim 1, wherein said backdrop comprises a three dimensional volume with an open face adjacent to said two-way mirror, said three dimensional volume of said backdrop further comprising interior surfaces of a light absorbing black material, and said camera is positioned at a distal position of the three dimensional volume with respect to the two-way mirror.

14. The telepresence system of claim 1, wherein said backdrop comprises a three dimensional volume with an open face adjacent to said two-way mirror, said three dimensional volume of said backdrop further comprising interior surfaces of a light absorbing black material, and said camera is positioned at a distal position of the three dimensional volume with respect to the two-way mirror, and said camera views a mirror that reflects a view toward the two-way mirror that in turn reflects a view toward the observation zone.

15. The telepresence system of claim 1, wherein said two-way mirror is angled to reflect the observation zone as viewed by said camera positioned below said two-way mirror.

16. The telepresence system of claim 1, wherein the two-way mirror is angled to reflect the observation zone as viewed by said camera positioned above the two-way mirror.

11. A telepresence system comprising:

an image display device comprising an image area;

a panel comprising a first edge near a first edge of said image display device;

a beamsplitter bisecting a volume disposed between said panel and said image display device, wherein a first edge of said beamsplitter is adjacent said panel; and

a camera with a view of said beamsplitter through an aperture in said panel.

12. A telepresence system comprising:

a display device;

a beamsplitter adjoining said display device along a first line, wherein said display device and said beamsplitter form a first angle with said first line being a vertex of said first angle; and

a panel adjoining said beamsplitter along said first line, wherein said beamsplitter and said panel form a second angle with said first line being a vertex of said second angle, wherein said first angle and said second angle are equal and are on opposite sides of said beamsplitter.
