    • 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 comprises a display screen, a camera system, and a projector. The display screen has a first surface and a second surface, and the camera system is positioned to capture images of objects through the display screen. The projector is positioned to project images onto a projection surface of the display screen, wherein the projected images can be observed by viewing the second surface. The system includes a first filter disposed between the camera and the first surface, where the first filter passes light receives by the camera but substantially blocks the light that is produced by the projector.
    • 本发明的实施例涉及一种视觉协作系统,其使地理分布的组能够参与面对面的交互式协作视频会议。 一方面,视觉协作系统包括显示屏,相机系统和投影仪。 显示屏具有第一表面和第二表面,并且照相机系统被定位成通过显示屏捕获物体的图像。 将投影仪定位成将图像投影到显示屏幕的投影表面上,其中可以通过观察第二表面来观察投影图像。 该系统包括设置在照相机和第一表面之间的第一过滤器,其中第一过滤器通过照相机接收光,但基本上阻挡由投影仪产生的光。
