Abstract

A multiple input rotary dial user interface device and system is provided. The rotary dial user interface device may include a rotationally fixed touchpad, disposed within a center of a rotatable dial. Although fixed rotationally, the touchpad of the rotary dial user interface device may move in a linear axial direction, along the rotational axis, with or independently of the rotary dial. In addition to providing input by rotating the rotary dial, a user can provide input via touching the touchpad, actuating the touchpad, and/or actuating the rotary dial in the linear axial direction. In some cases, the rotary dial user interface device may employ the use of a static rotary encoder sensing rotation of an encoder wheel affixed to the rotary dial to determine momentum characteristics associated with the dial.
