Patent US 5,486,001

An instructional aid (10) for enabling and assisting a person to emulate a predetermined movement such as a golf swing including an image/data capturing device (11) for scanning, capturing and storing the image/data signals of the person's golf swing or movement, and a transceiver (14) for transmitting the image/data signals over a communications network (15) to a remote computer (17). The computer (16) contains a database (17) which stores in digital form image signals and bio-mechanical data of a number of preselected swing or movements. The computer (16) analyzes the person's image/data signals against image/data of a preselected swing and generates in digital form further visual images/data signals which can be transformed so as to assist or enable a person to be able to emulate the preferred swing. The instructional aid may also be used for analyzing or reporting on particular geographical regions or objects and provides a specialized presentation for development of that region or object from information stored in the computer database.
