Abstract
A method and an arrangement for the operation of a prize wheel by a user. The position of the center of gravity and the position of a hand of the user are ascertained using a camera; a height threshold is fixed in relation to the center of gravity; if the position of the hand exceeds the height threshold, a rotation phase is started, the rotation which is carried out by the movement of the hand of the user is continuously ascertained, and a rotational angle is ascertained; the angular speed, i.e. the rate of change over time of the ascertained angle, is determined; the rotation phase is ended, and an angular speed, is fixed as the initial rotational speed; and a free rotation phase is started. The prize wheel is further rotated, and the prize wheel is continuously braked and comes to rest upon a specified end position.
