Development of a Wristwatch Equipped with Exercise Intensity Measurement and a Link Function with a Smartphone

Abstract

  CASIO Corporation has developed "GBA-800" as a "G-SHOCK" brand watch targeted at the scene and fashion like athleisure. In order to realize a more practical product sports watch, we have developed an algorithm that enables low-power implementation of a function that constantly measures the number of steps and determines exercise intensity using an accelerometer. And a dedicated smartphone application enables easy management of daily exercise intensity. This paper explains the technical summary of the development of GBA-800.
