Abstract: A system has footwear and a striking device. The striking device has a shaft connected to a striking surface for contacting an object. A sensor affixed to the shaft changes electrical resistance when the striking surface is swung to contact the object to in turn generate a signal reflective of the deflection of the shaft. The footwear is configured with an array of sensors that change at least one electrical characteristic upon deflection when the player is operating the striking device. The footwear is to send signals reflective of the deflection of the feet as the shaft is swung. The signals reflective of the deflection of the shaft and the footwear are sent to a cell phone, notebook, PC or the like suitably programmed to present audio and visual images of the feet positions and movement and movement of the striking device (e.g., golf club, racket).
