SMART STRAP FOR ANALOG WRISTWATCH

摘要

Disclosed is a smart strap, for an analog wristwatch, attachable to the wristwatch via a pin. The smart strap comprises an accelerometer, which accelerometer is coupled to the pin via a mechanical coupling. The mechanical coupling is arranged to convey to the accelerometer movement of mechanics of the wristwatch and movement of the wristwatch, when the absolute value of acceleration of the movement is at least 0.05 G and the duration of the movement is at most 0.5 s, to provide measurement data. The smart strap also comprises communication means configured to communicate the measurement data from the accelerometer to a mobile communication device.
