Flow and validation of our method. The estimation equation, P(t k ), is constructed during the modeling session. t k is the discrete time. The root-mean-square error (RMSE) between the estimated target position, \( {\widehat{P}}_{\mathrm{estimated}} \), and the actual target position, Pactual, is calculated during the validation session. C: coefficients for P(t k ). W(t k ): the position and velocity of the infrared reflective (IR) marker at t k . 2D: two-dimensional
