An interactive desktop system comprising a work surface, a video projector for displaying images in a display area, an camera for capturing images present on the work surface, and an image processing computer coupled to the projector and to the camera, and adjustment means for adjusting, in response to user action, the field of view of the camera. In the preferred embodiment, the adjustment means comprises a frame including a housing in which the camera is disposed, the frame being movable (in a manner similar to that of a shade of a desk lamp) whereby the field of view of the camera is altered. In another embodiment, the image processing computer is adapted for modifying, in response to a user input, the dimensions of the display area and/or the resolution of the images displayed therein. The image processing computer may include means, responsive to a user input designating a position on the work surface, for causing movement of the housing whereby the said designated position is moved to within the field of view of the camera. <IMAGE> |
