Abstract

A system in accordance with one embodiment of the present invention comprises a device for facilitating video communication between a remote participant and another location. The device can comprise a screen adapted to display the remote participant, the screen having a posture adapted to be controlled by the remote participant. A camera can be mounted adjacent to the screen, and can allow the subject to view a selected conference participant or a desired location such that when the camera is trained on the selected participant or desired location a gaze of the remote participant displayed by the screen appears substantially directed at the selected participant or desired location.

Claims

1. A communication system comprising:

a screen adapted to display a subject, the screen having a posture controllable by the subject;

a camera adjacent to the screen and trainable on a desired location, the camera allowing the subject to view the desired location;

wherein motion of the camera relative to the screen is confined such that when the camera is trained on the desired location, a gaze of the subject displayed by the screen appears substantially directed at the desired location;

a base;

a frame including;

a platform rotatably mounted to the base,

a trunk pivotably mounted to the platform;

a neck pivotably mounted to the trunk;

an extension motor mounted to the platform and adapted to pivot the trunk relative to the platform; and

a pivot motor mounted to the platform and adapted to pivot the neck relative to the trunk;

wherein the screen is connected with the neck.

2. The system of claim 1, wherein:

when the camera is zoomed in the screen moves towards the desired location by pivoting the trunk forward relative to the platform.

3. The system of claim 1, wherein:

when the camera is zoomed out the screen moves away from the desired location by pivoting the trunk backward relative to the platform.

4. A communication system, comprising:

a base;

a frame including;

a platform rotatably mounted to the base,

a trunk pivotably mounted to the platform;

a neck pivotably mounted to the trunk;

a display screen connected with the neck and adapted to display a subject;

a camera adjacent to the display screen and trainable on a desired location, the camera allowing the subject to view the desired location; and

a remote terminal accessible to the subject;

wherein movement of the platform, the trunk, and the neck is controllable by the subject by way of the remote terminal.

5. The system of claim 4, further comprising:

a means for pivoting the trunk relative to the platform; and

a means for pivoting the neck relative to the trunk.

6. The communication system of claim 4, wherein the desired location includes a selected participant.

7. The communication system of claim 6, wherein the selected participant is one of a person, a second display screen, a telephone, an intercom, a video camera, a videoconferencing system, an audio recording device, and an audio/video recording device.

8. The communication system of claim 4, wherein the display screen is sized such that at least a portion of the subject including a face can be displayed at substantially full scale.

9. The communication system of claim 4, further comprising:

at least one speaker for reproducing remote sounds from a remote location so that the remote sounds are audible at the desired location.

10. The communication system of claim 4, further comprising:

at least one microphone for detecting sounds at the desired location so that the sounds at the desired location can be communicated to the subject.

11. The communication system of claim 10, wherein:

the remote terminal displays an image captured by the camera to the subject; and

movement of the platform, the trunk and the neck is controllable by a control arrangement connected with the remote terminal; and

the control arrangement includes a means for controlling the posture of the display screen, thereby controlling a field of view of the camera.

12. The communication system of claim 11, further comprising:

at least one remote speaker connected with the remote terminal for reproducing sounds audible at a selectable proximity to the desired location so that the sounds are audible to the subject.

13. The communication system of claim 11, further comprising:

at least one remote microphone connected with the remote terminal for detecting remote sounds produced by the subject so that the remote sounds can be reproduced by the at least one speaker.

14. The communication system of claim 11, wherein the means for controlling the posture is at least one of a plurality of buttons, a keyboard, a joystick, a touch display screen, and a touchpad.

15. The communication system of claim 11 wherein the control arrangement further includes:

a means for zooming the camera so that the subject can adjust a field of view of the camera.

16. The communication system of claim 15, wherein the means for zooming is at least one of a plurality of buttons, a joystick, a keyboard, a touch display screen, and a touchpad.

17. The communication system of claim 11, wherein the control arrangement further includes:

a means for communicating a nonverbal gesture;

wherein the nonverbal gesture includes movement of the display screen.

18. The communication system of claim 17, wherein the means for communicating a nonverbal gesture is at least one of a plurality of buttons, a keyboard, a joystick, a touch display screen, and a touchpad.

19. The communication system of claim 17, wherein the nonverbal gesture is at least one of a nod performed by the display screen to indicate a positive response and a shake performed by the display screen to indicate a negative response.

20. The system of claim 17, wherein the nonverbal gesture is text displayed on the display screen.

21. The communication system of claim 11 wherein the at least one microphone is a microphone array adapted to identify a direction of origin of a sound.

22. The communication system of claim 21, wherein the remote viewer provides a visual indication of the direction of origin of a sound to the subject.

23. The communication system of claim 21, wherein the remote viewer provides an audible indication of the direction of origin of a sound to the subject.
