Abstract: The present invention permits a dual mode use of a display screen of which in one mode the display screen is accessible and in the second mode has placed in front of the display screen videoconferencing eye contact components. The invention utilizes a uniquely hinged folded eye contact component apparatus which permits in the major embodiment of the present invention all of the eye contact components including the partially silvered mirror to fold with more than a one-half rotational turn entirely over to the back side of the flat panel display completely out of view. The folded eye contact components are attachable to existing flat panel displays and also are illustrated built in as a part of the flat panel housing. The same hinged folding function is also demonstrated as being suspended separate from the monitor so that no attaching to the display is required.

Abstract: The present invention enables eye contact between conferees during a teleconference using a terminal equipped with a beamsplitter for reflecting an image of a video display so that only the reflection and not a direct view of the display is seen by the conferee. The camera is positioned behind the viewing side of the beamsplitter to capture the conferee's image through the beamsplitter. The direct view of the display is blocked by an image blocking film applied between the beamsplitter and the display. Blocking the direct view of the video display greatly improves teleconferencing by eliminating the distraction of simultaneously viewing both the video display and the reflection of the display. The present invention also substantially improves available desktop space, functional options by providing a direct view and a reflected view of the display, and portability.

Abstract: An improved rear projection screen for projecting a three-dimensional head or face is designed to accurately match the apparent movement of a imaged person eyes to movements of an observer, thereby maintaining eye contact between the imaged person and the observer as the observer moves relative to the image. This unique effect called "visualactivity" enables either a recorded or a live image of a person to engage observers with eye contact in a natural and interpersonal way despite movement of the observers relative to the image. This effect is achieved by projecting an image onto the convex side of a rear projection screen that roughly has the shape of a human head and face but is configured with proportions that are different from the natural proportions of the imaged person's face. When viewed from the concave side, this combination produces a realistic human face that appears to turn to accurately track an observer's movements.

Abstract: An improved desktop projection display system which effectively utilizes desktop space by producing a large image that appears to be at the rear edge of the desk. The display is compact because it uses a transparent-reflective panel (i.e., beamsplitter) to reflect a screen image through the same space occupied by the projection beam. This is achieved by projecting through a transparent-reflective panel onto a front projection screen located on the desk surface. An image formed on the front projection screen is then reflected by the transparent-reflective panel creating the appearance, to the observer, that the reflected front projection screen is positioned toward the rear of the desk surface. This invention greatly improves desktop display ergonomics for large display viewing by providing a sufficient distance between the observer seated at a desk and the display image.

Abstract: An improved desktop projection display system which effectively utilizes desk top space by producing an image that appears to be at the rear edge of the desk. The display is compact because it uses a transparent-reflective panel (i.e., beamsplitter) to reflect a screen image through the same space occupied by the projection beam. This is achieved by projecting through a transparent-reflective panel, angled at approximately 45 degrees to the projection beam, onto a front projection screen located on the desk surface. An image formed on the front projection screen is then reflected by the transparent-reflective panel creating the appearance to the observer that the reflected front projection screen is positioned toward the rear of the desk surface. This invention greatly improves desktop display ergonomics for large display viewing by providing a sufficient distance between the observer seated at a desk and the display image.

Abstract: A compact teleconferencing eye contact terminal that can be integrated with a multitude of image display devices. Eye contact is achieved between conferees who share similar eye contact terminals by the use of a uniquely configured integral beam-splitter. The beam-splitter is coated over all or part of its surface so that a region acts as a partially-silvered mirror. The beam-splitter is integral to a transparent substrate member that is configured with subtle curves that permit only a portion of its surface, forming the integral beam-splitter, to be angled at or near 45 degrees from the viewing surface of a display screen. By doing so, the angled portion forming the integral beam-splitter is seamlessly suspended in front of the viewing surface without interfering with the viewing. This uniquely configured beam-splitter permits image capturing without the great increase in depth of terminals or loss of display brightness necessitated by prior art eye contact systems employing partially-silvered mirrors.

Abstract: A teleconferencing system that allows for natural eye contact between conferees is provided. The system comprises two or more terminals which are connected to allow a teleconference to occur. Each terminal comprises a screen to display an image of the remote conferee and a video camera to transmit an image of the local conferee to the remote screen. The video camera is conveniently located above the screen, beyond the perimeter of the image. Microphones and speakers are also provided to allow the conferees to hear as well as speak to one another. Eye contact is provided, despite the mounting of the camera above eye level, by image manipulating the image of a conferee to remove any distortion caused by camera placement and to redirect the apparent direction of the conferee's gaze.
