ABSTRACT:
A sports training aid has a pair of foot sensors, insertable in a pair of shoes, which generate measurement signals indicative of weight applied to each of the foot sensors. The training aid compares the measurement signals with a specified range of values and produces audible sounds indicative of the relationship between those measurement signals and the specified range of values, thereby providing the training aid's user with immediate audible feedback regarding weight shifts. A grip sensing version of the sports training aid uses a grip pressure sensor which generates a measurement signal indicative of grip pressure applied to the handle of a swingable object, such as a golf club or baseball bat. When the user's grip pressure falls outside specified threshold values, audible tones are generated. In both versions, the user receives the audible feedback signals via a headset worn while using the sports training aid. A spinal tilt version is used to train a person to maintain proper spinal tilt during a sports motion, and a shoulder rotation is used to train a person to achieve a proper degree of shoulder rotation during a sports motion such as the golf backswing. In each version, the sensor(s) include a transmitter which transmits the measurement signals at a predefined frequency. The transmitted measurement signals are received by a comparator which compares the received signals with the specified range of values. As a result, the sensors and comparator need not be physically connected.
