Abstract
An instrument cluster assembly includes a pointer assembly that generates a pointer image that moves along the scale to point to a portion of the scale that corresponds with the measured parameter. The pointer assembly projects the pointer image such that a solid pointer is not required and therefore does not obstruct any portion of the dial face. The pointer image tracks along the oval shape of the scale without the limitations imposed on a physical pointer rotated about a fixed central axis.
