SWING ACCURACY AND REPLACEMENT DETERMINATION DEVICE OF TABLE TENNIS RACKET

摘要

The present invention comprises: a table tennis racket including a handle for a grip and a hitting part connected to the handle and hitting a table tennis ball; a detection sensor unit installed on the handle and repeatedly storing acceleration information and angular velocity information generated when the table tennis racket swings; a determination unit for determining swing accuracy through calculating and comparing a swing trajectory of the table tennis racket based on the detection information detected by the detection sensor unit; and a replacement decision unit that calculates and stores the amount of impact applied to the hitting part, detects a change in the amount of impact, and guides the decision of replacement timing of the hitting part.;COPYRIGHT KIPO 2020
