The invention relates to a method and an arrangement for the operation of a prize wheel (3) by a user (1). According to the invention, the position of the center of gravity (11) and the position of a hand (12) of the user (1) are ascertained using a camera (2); a height threshold (13) is fixed at a specified value in relation to the center of gravity (11); if the position of the hand (12) exceeds the height threshold (13), a rotation phase is started, the position of the hand (12) being continuously ascertained during said rotation phase; the rotation which is carried out by the movement of the hand of the user (1) is continuously ascertained, and a rotational angle (w) is ascertained; the angular speed (w), i.e. the rate of change over time of the ascertained angle (0), is continuously determined; the rotation phase is ended, and an angular speed (w) which is continuously ascertained, preferably immediately prior to the end of the rotation phase, is fixed as the initial rotational speed (ωe); and a free rotation phase is started after the end of the rotation phase. The prize wheel (3) is further rotated at the initial rotational speed (ωe) as the initial speed, and the prize wheel (3) is continuously braked and comes to rest upon a specified end position, said end position being kept available. |
