“…Two angular features are extracted from the driving gesture, obtained from the skeleton image of the player, are given as αL = angle (SC, HC, HaL) (13) αR = angle (SC, HC, HaR) (14) where, αL is the angle between SC, HC and HaL, and αR is the angle between SC, HC and HaR. For straight driving, αL ≈ αR.…”
