Method for detecting a golf motion using an electronic device such as a watch

A golf-stroke-detecting method configured to operate on an electronic device, worn on the wrist or on another part of the arm, such as a bracelet or a watch, comprising one or more angular or linear measuring means, notably for orientation, speed or acceleration, such as a three-axis accelerometer and/or a three-axis gyroscope and/or a three-axis magnetometer, cooperating with a computing unit and a memory space, a golf stroke being defined by a golf motion performed by a user manipulating a golf club, the club having a face, and causing said club to describe a typical trajectory resulting in an impact between the face of the golf club and a golf ball, the method comprising the implementation of a golf-motion-detecting function and an impact-detecting function, the motion-detecting function being configured to detect, at any time, a golf motion associated with one golf motion among a set of predefined golf-stroke motions, notably a drive, a swing and a putt, and the impact-detecting function being configured to synchronously detect an impact between the golf club and the golf ball, based on measurements carried out by at least one sensor embedded in the electronic device.
