1. A video conferencing system, comprising:
- a video projector that is controllable to project far-end video;
a video camera configured to capture, as captured video, video encompassing a 360 degree horizontal panorama;
wherein the video projector is controllable to pan and tilt independently of the video camera; and
operating logic configured to perform actions comprising;
determining a first display area suitable to receive the far-end video projected by the video projector;
determining a second display area suitable to receive the far-end video projected by the video projector;
analyzing the captured video to determine a first location of a first user;
selecting the first display area such that the video camera is between the first location and the first display area;
controlling the video projector to project the far-end video onto the first display area based at least in part on determining that the first user is speaking;
analyzing the captured video to determine a second location of a second user;
selecting the second display area such that the video camera is between the second location and the second display area;
determining that the second user is speaking;
controlling the video projector to project the far-end video onto the second display area; and
extracting a portion of the captured video that contains a face of the first user to produce near-end video.

Abstract
A video conferencing device has a projector that can be controlled to project far-end video onto different available display surfaces. A panoramic camera is mounted so that it captures a horizontal panorama that includes near-end users. When projecting far-end video, a display surface is selected based on the position of the users. Specifically, a display surface is selected such that when gazing at the far-end video the faces of the user are visible from the panoramic camera.

4. A device, comprising:
-
a projector positioned within a first environment; a camera; and logic configured to perform actions comprising; receiving an image from the camera, the image associated with the first environment; determining, based at least in part on the image, a first display area suitable to receive content projected by the projector; determining, based at least in part on the image, a second display area suitable to receive the content projected by the projector; selecting the first display area such that the camera is between a first user and the first display area; controlling the projector to project the content onto the first display area, the content associated with a second environment remote from the first environment; selecting the second display area such that the camera is between a second user and the second display area; and controlling the projector to project the content onto the second display area. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)
