Abstract: The system monitors a user's key physical movements when performing a particular activity, such as a golf swing, and signals visually and/or aurally when a single (or several) error(s) is/are committed, for the purpose of encouraging faster learning of fundamentally sound physical skills. Mental conditioning is achieved when the effects of repeatedly listening to the specially constructed and authored audio conditioning programs during practice sessions and games are combined with the above described physical monitoring effects of the system. Better physical execution of a selected technique or skill results, and the user experiences the benefits of mental conditioning on his/her playing performance.
