Physical activity training device and method

A training device (Figs. 1 and 2) for a person performing a physical activity wherein the proper performance thereof is related to the proper movement by the person (10). The device comprises a movement sensor (40), a trigger event sensor (50) for sensing the occurrence of a specific physical trigger event, a processor (60), an electronic memory (70), and a protective enclosure (95). The movement sensor (40) provides movement signal values to the processor (60), which is able to store these movement signal values in the memory (70). The trigger event sensor (50) provides trigger event signal values to the processor (60), such trigger event signal values corresponding to the occurrence of the specific physical trigger event near the device (Figs. 1 and 2). The processor (60) is able to store the trigger event signal values in the memory (70), and evaluate the trigger event signal values (Figs. 4A-4D, and 90) to determine if the specific trigger event has occurred.
