Golf device and method

摘要

The invention relates to a portable device and a method for monitoring the performance a sportsman performing a plurality of motor acts, such as golf swings. The device comprises at least one sensor providing an output signal, the sensor being responsive to body movements of the sportsman. A signal processing unit is used for extracting data on the course of each of the plurality of motor acts from the sensor output signal, and a computing unit is used for determining, based on the data on the course of the plurality of motor acts, at least one characteristic number describing the repeatability of the motor act. By the means of the invention, the handicap number of the golfer can be predicted with good accuracy by monitoring several his or her subsequent swings.

1. A portable computing system for monitoring the performance of a sportsman performing a plurality of motor acts, the system comprising:
a portable main device containing at least a timing device, a signal processing unit, a computing unit and a display unit, an external sensor unit attachable to an object used by the sportsman in said motor acts, the sensor being responsive to movement and arranged to generate a sensor output signal, wireless communication means adapted to enable wireless communication of the sensor output signal from the external sensor to the main device, wherein the signal processing unit being arranged to extract data on the course of each of the motor acts from the sensor output signal, said data including key time points of the motor acts, the computing unit being arranged to use said extracted data from the signal processing unit to calculate at least the statistical deviation of a series of repeated motor acts of said sportsman, and based on the repeatability of said motor acts, to calculate a handicap value predictive of the performance of said sportsman; and the display unit being arranged to display said calculated handicap value.
