“…Researchers seek to couple well-known models of IMU sensor dynamics with novel human kinematic models in order to fuse human motion capture measures of interest from the body-worn IMU data. To date, IMUs have found use in many human motion applications, including clinical sciences [ 1 , 2 , 11 , 12 , 13 ], sports performance [ 14 , 15 , 16 , 17 , 18 ], activity recognition [ 19 , 20 , 21 , 22 , 23 ], occupational ergonomics [ 3 ], and even spacesuit fit evaluation [ 24 ].…”
