Abstract
Device for remote testing, augmented reality or other visualization needs includes a frame configured to be situated on a person's head, a display assembly on the frame, and a combiner assembly arranged on the frame in a position at least partly in front of right and left eyes of the person. The combiner assembly allows simultaneous viewing by the person of an environment in front of the person and content on the display assembly. The combiner assembly includes an inwardmost layer that is reflective and reflects content of the display assembly to the person's eyes, an intermediate layer that controls light transmission through the combiner assembly, and an outwardmost layer that covers the second layer and provides notification of intrusion attempts into the second layer.
