Motion monitor

Abstract: A method for evaluating the motion of a moveable object relative to a reference object includes locating the reference object within a three-dimensional coordinate system having first, second, and third positional coordinates such that the position of the reference object is characterized by respective values of first, second, and third positional coordinates. A mechanism is provided having a plurality of visual indicators. A sensor is configured to detect the position of the moveable object within the three-dimensional coordinate system substantially apart from any dynamic property inherent in the movement of the moveable object. An acceptable minimal number of sampling events is determined and providing a sensor having sufficient response rate as to be capable of determining respective positions of the moveable object as the moveable object moves relative to the reference object such that the number of the respective positions exceeds the acceptable minimal number for any maximum velocity of the moveable object manually achievable by the user.
