METHOD AND APPARATUS FOR IDENTIFYING FAULTS IN A GOLF SWING OR THE LIKE

摘要

An aid (10) is planted for observing head movements during a golf swing or the like. The aid (10) includes a light source (14), such as a laser, that is mounted to a person's head by fastening the light source to a hat (12). The light source (14) projects a light spot (16) into a hitting area (17) to provide a continuous visual indication of head movement during the swing. The observed path of the light spot movement is compared with a predetermined swing fault path to aid the person in identifying his potential swing faults. A mercury switch (22) is provided to automatically activate and deactivate the light source (14) when the head is lowered or upright.
