Abstract: A system is provided for locating a target, such as a person, relative to a projection screen, the system including two infrared light sources for casting separate shadows of the target on a translucent screen, such as those commonly used for back-projection displays. A sensitive video camera with an infrared filter over the lens that blocks all visible light is located behind the screen. This video camera captures a crisp silhouette for each of the shadows of the target. Image processing techniques detect the person's location as well as typical gestures, such as indicating or pointing to an area of the screen. This allows natural interaction with the display, for example, controlling a pointer or cursor on the screen by pointing at the desired area.

Abstract: Inputs drawn on a control surface or inputs retrieved based on tokens or other objects placed on a control surface are identified and a view of a camera, or a virtual view of a camera or camera array is directed toward a corresponding location in a scene based on the inputs. A panoramic or wide angle view of the scene is displayed on the control surface as a reference for user placement of tokens, drawings, or icons. Camera icons may also be displayed for directing views of specific cameras to specific views identified by any of drag and drop icons, tokens, or other inputs drawn on the control surface. Clipping commands, are sent to a display device along with the wide angle view which is then clipped to a view corresponding to the input and displayed on a display device, broadcasting mechanism, or provided to a recording device.

Abstract: This invention relates to a force-feedback apparatus which includes a stylus that is equipped with an electromagnetic device or a freely rotating ball. The stylus is functionally coupled to a controller which is capable of exerting a magnetic field to the electromagnetic device or to the rotating ball, which results in a force being created between the stylus and a surface. This invention also relates to a method of using a force-feedback stylus including moving a force-feedback stylus over a surface, controlling a force-feedback device via a controller coupled to the force-feedback stylus and applying a force to the force-feedback stylus via the force-feedback device, the force being determined for at least features on the surface.
