An interactive control system and related apparatus uses disposable, low-cost control objects, such as cards or leaflets or three-dimensional visual shapes, for controlling and navigating through electronic "menu" programs of electronic equipment. The system incorporates visual detection equipment, of known type and function, that is capable of recognizing the color and locating the spatial orientation of a particularly shaped and colored control object. When the control object is displayed to a visual sensor of the visual detection equipment, an associated microprocessor converts the shape, color and spatial orientation of the control object into electronic signals for directing and controlling an external electronic program in a known manner. Because the control objects are passive and non-electronic, they can be made at very low cost and can be treated as disposable. In addition, printed matter can be included on their exposed surfaces to provide advertising and instructional material. The visual detection equipment is programmed to respond to the shapes, positions, orientation, colors and changes of any of these parameters as if the change were a movement or "click" of a computer "mouse" device. Multiple control objects of different shapes and/or colors may be used with the same equipment for different purposes. Different shapes may be associated with different programs, and different ranges of colors may produce multiple signal responses within a particular program. |
