Abstract

An example device may include an electronic display configured to generate an augmented reality image element and an optical combiner configured to receive the augmented reality image element along with ambient light from outside the device. The optical combiner may be configured to provide an augmented reality image having the augmented reality image element located within a portion of an ambient image formed from the ambient light. The device may also include a dimmer element configured to selectively dim the portion of the ambient image in which the augmented reality image element is located.
