“…In contrast, inverse dynamicsbased optimization formulation treats motion as solution variables, and the joint forces are computed from EOM that avoids their numerical integration (Bessonnet et al, 2010;Channon et al, 1992;Chevallereau and Aoustin, 2001;Ren et al, 2007). Besides these two methods, the predictive dynamics approach has been recently used to simulate human motions Chung et al, 2007;Kim et al, 2005Kim et al, , 2008Kim et al, , 2009Wang et al, 2005Wang et al, , 2007Xiang, 2008;Xiang et al, 2007Xiang et al, , 2009aXiang et al, , 2009bXiang et al, , 2010aXiang et al, , 2010bXiang et al, , 2010c. Similar efforts on alternative formulations for dynamic human motion prediction were also made in the literature, such as direct collocation method (Ackermann and van den Bogert, 2010) and temporal finite element method (Eriksson, 2008;Kaphle and Eriksson, 2008;Eriksson and Nordmark, 2010).…”
