New Research: Assessing Agreement and Usability of Kinematic Measures Between Markerless and Marker-Based Motion Capture Systems During Jumping Activities

An NBA-funded study found that markerless cameras mounted anywhere from 1.4 to 3 meters high produced comparably accurate jump-landing kinematics, and that both novice and experienced users could operate the system with confidence.
