Abstract:
A video game system comprising:a) a personal computer comprisingi) computer processing means for executing a video game program, said computer processing means generating a plurality of display frames representative of images to be displayed on a video monitor screen;ii) video adapter means coupled to said computer processing means for processing said display frames and generating analog display signals proportional thereto and synchronization signals correlated to said analog display signals, said analog display signals and said synchronization signals being output to a video port associated therewith;b) a peripheral adapter external to said personal computer and coupled to said video port, said peripheral adapter configured to output said analog display signals and said synchronization signals to a video monitor, said peripheral adapter further configured to output said synchronization signals to a video game peripheral device;c) a video monitor coupled to said peripheral adapter for processing said analog display signals and said synchronization signals to display images on a screen associated therewith; andd) a video game peripheral device connected to said peripheral adapter, comprisingi) a photosensitive transducer having a field of view, said photosensitive transducer outputting an electrical signal proportional to light sensed in its field of view,ii) means for receiving said synchronization signals from said peripheral adapter,iii) peripheral processing means for processing said electrical signal from said photosensitive device and said synchronization signals and for generating a peripheral position signal indicative of the relative position of the field of view of said photosensitive transducer on said screen; andmeans for transmitting said peripheral position signal to an input port on said personal computer for further processing.
