While wearing four wireless, military-grade, inertial sensors, the player simply hits balls during live batting practice, off a tee or even during a game. The sensors stream 3D-motion data in real time to a tablet computer, on which the K-Baseball software assesses the player’s motion and creates easy-to-understand reports and graphs that explain how the hitter swings. You also can compare the hitter’s swing to pro ranges to better understand the hitter in the context of the best players in the world. The reports demonstrate the player’s strengths and weaknesses, so you use patented biofeedback to both identify and correct mechanical issues and limitations.
