摘要： A display-camera system includes a liquid crystal panel having a screen side and a back side that is opposed to the screen side. A visible light camera is positioned a first spaced distance from the back side such that a field of view of the camera encompasses all or a fraction of an area of the liquid crystal panel. A visible light source is positioned a second spaced distance from the back side and outside of the field of view of the camera. A diffuser is positioned between the visible light source and the back side.

摘要： In one aspect, a method includes capturing images of a first participant through a display using a camera. The display is located between the first participant and the camera. A video stream of images of a second participant is also received. The images of the second participant are shifted in accordance with a shift vector. The shift vector places the images of the second participant's face in approximate alignment with the eyes of the first participant and the lens of the camera. The shifted images are projected on the display using a projector.

摘要： Embodiments of the present invention are directed to video-conferencing systems that create eye contact and accurate gaze awareness between video-conferencing participants. In one aspect, a method includes capturing images of a first participant through a display using a camera (801). The display is located between the first participant and the camera. A video stream encoding images of a second participant (802,905) is also received. The images of the second participant are shifted in accordance with a shift vector. The shift vector places the images of the second participant's face in approximate alignment with the eyes of the first participant and the lens of the camera (803). The shifted images are projected on the display using a projector (804).

摘要： Video conferencing methods and systems that enable shared content to be displayed in a separate window within a screen or in a separate display are described. In one aspect, a method for establishing a video conference with shared content using a computing device includes capturing images of a first participant through a screen using a camera. The screen is located between the first participant and the camera. The method also includes projecting images of a second participant on the screen to be viewed by the first participant using a projector, and displaying shared content separate from the images of the second participant. The shared content is to be presented in different format than the images of the second participant presented on the screen.

摘要： Embodiments of the present invention are directed to visual-collaborative systems enabling geographically distributed groups to engage in face-to-face, interactive collaborative video conferences. In one aspect, a visual-collaborative system comprises a transparent display (402) having a first surface (410) and a second surface (412); and a camera system positioned to face the second surface. The display is configured to show images that can be viewed by looking at the first surface. The display is also configured to transmit light scattered off of objects facing the first surface. The light passes through the display and is captured by the camera.

摘要： Embodiments of the present invention are directed to a visual-collaborative system enabling geographically distributed groups to engage in face-to-face, interactive collaborative video conferences. In one aspect, a visual-collaborative system (400) comprises a display screen, a camera system, and a projector. The display screen (402) has a first surface (410) and a second surface (416), and the camera system is positioned to capture images of objects through the display screen. The projector (404,602,702) is positioned to project images onto the first surface that can be observed by viewing the second surface. The wavelengths of light used to produce the projected images are different from with the wavelengths of light used to capture images.
