Methods and systems for controlling a rotary dial input device are provided. A dial of the rotary dial input device may have a specific mass that, in conjunction with a low-friction rotational bearing system, provides a momentum scrolling effect when physically spun and released. Upon spinning the dial freely, without subsequent user contact, the mass and velocity of the rotating dial provides momentum that causes the dial to continue to rotate for one or more revolutions. During this rotation a corresponding effect may be provided, or dynamically rendered, to a user interface display device. Such an effect may scroll a list of objects displayed at the same, or a substantially similar, rate of speed to that of the dial rotating under momentum.
