In the anterior–posterior direction, Pearson’s correlation, root mean squared error (RMSE), and normalized RMSE of the Kinect v2 depth camera (shown in darker color) and the pressure mat (shown in lighter color) compared against the force plate, separated by the type of VFBT exercise (i.e., color matching, hunting, ellipse, and bullseye shown in red, blue, green, and purple, respectively). Significant difference (p < 0.05) between sensors is indicated by *
