WRISTWATCH-TYPE SWING MEASUREMENT DEVICE WITH ACCELERATION SENSOR AND AUTOMATIC DRIVE METHOD USING CHARACTERISTIC MOTION EXTRACTION BY SAME

摘要

The present invention relates to a wristwatch-type swing measurement device with an acceleration sensor for automatic drive by extracting the characteristics of a two-step motion produced by the movement of an arm or a leg in a ball game and a method for driving the swing measurement device. A wristwatch-type swing measurement device according to the present invention includes a body (1) and a band (2) detachably attached to each other, wherein the body includes a case (3) enclosing a processor part (4), a sensor part (5), an input/output part (6), and a power supply part (7), and the band (2) is designed to have a band length adjustable according to the size of the wrist, the ankle, or the grip of an exerciser. The processor part (4) consists of a processor (11) and a memory (12), the sensor part (5) consists of an acceleration sensor (13), the input/output part (6) consists of at least one of an LCD (18) and a speaker, the power supply part (7) consists of a battery (14) and a charging circuit (15). The processor (11) calculates the present measurement according to the characteristics of a swing motion based on the acceleration detected by the acceleration sensor so as to update the maximum value stored in the memory with the present measurement and to control the input/output part to generate an event for notifying the user of the revision of the maximum value, if the present measurement is greater than the maximum value stored in the memory.
