Abstract: A sports training aid comprising a body unit (110) attachable to a person's body or the person's sports implement wherein the body unit (110) is provided with a positioning sensor module; a feedback stimulator; and a processor.

Abstract: A sports training aid comprising a body unit, attachable to a person's body or the person's sports implement, is provided with a positioning sensor module; a feedback stimulator; and a processor. The sports training aid is configured to provide instantaneous feedback on motion faults of a studied sports motion, and the body unit is intended to be attached to a person's body (or a person's sports implement) at a representative location, the location being bound to travel a path representative of the studied sports motion, and the positioning sensor module comprises acceleration sensors and gyro sensors. The processor is configured to determine a still position corresponding to an event wherein the body unit is determined to be still, to keep track of the sensor module's movements relative to the still position, and to activate the feedback stimulator in real time, upon detection of a sports motion fault.

Abstract: A motion training aid system for a person or animal to train bodily movement is provided. The system includes a motion sensor unit that attaches to a body part of the person or to an implement used by the person, a processor, and a stimulator attachable to the body of the person that receives a command and elicits a stimuli perceptible by the person. The motion sensor unit provides motion data to the processor, and the processor, based on the motion data from the motion sensor unit, tracks three dimensional positions of the motion sensor unit. The processor compares the motion sensor unit position with a reference track, and depending on the motion sensor unit position relative to the first three dimensional track, sends to the stimulator, a command to elicit an electrical stimulus when the motion sensor unit has reached a predefined deviation from the reference track.
