Title: Rotary pushbutton and touchpad device and system and method for detecting rotary movement, axial displacement and touchpad gestures

Abstract: A rotary pushbutton and touchpad device, a system and a method detect rotary movement, axial displacement and touchpad gestures. The device has a knob which may rotate about an axis of rotation, may move upward and downward on the axis of rotation, and may have a touchpad. The touchpad may be fixedly connected to a rotary girder and/or a shaft clip within the knob which may prevent the touchpad from rotating when the knob is rotated. A substantially hollow and cylindrical outer shaft may be fixedly connected to the knob so that rotation of the knob rotates the outer shaft. The shaft clip may be fixedly connected to an actuator shaft which extends through the interior of the outer shaft and conveys axial displacement of the knob. Shutters extending from the outer shaft may rotate into or away from a position between a light emitter and a light pipe.
