METHOD AND SYSTEM FOR CHARACTERIZING SPORTING ACTIVITIY

摘要

A system is proposed for characterizing the performance of a sportsman. The system is capable of using motion data it receives describing a movement during the sport, to distinguish the type of sport, and type of stroke, which is being played. The system can furthermore detect the quality of a stroke involving an impact (e.g. an impact between an item of sports equipment and a ball), based on the observation that a good stroke will be in a “sweet spot” in which the amount of vibration caused by the impact is limited.

1. A method of characterizing a movement during the performance of a sport, using a motion sensor releasably attached to an item of sports equipment to generate motion data describing the movement, the method comprising the steps of:
(i) receiving a series of motion readings from the motion sensor, wherein each motion reading describes the movement at a sampling point during the movement; (ii) producing an information digest from the received series of motion readings; (iii) comparing the information digest against each of a plurality of pre-determined templates, to select a most closely matching template from the plurality of templates, wherein each of said plurality of templates describes a respective type of stroke, wherein the pre-determined templates include templates which describe a respective plurality of strokes in the same sport; and (iv) characterising the movement as the stroke corresponding to the most closely matching template.
