Abstract
A partial electronic see-through HMD includes one or more subassemblies that occlude a central portion of a user's field of view (the peripheral portions of the user's field of view may remain unobstructed). Each subassembly includes an outward facing camera, a display, and an eyepiece. Images of the occluded central zone are captured by the camera and projected to the user via the display and eyepiece. The projected images can also include electronic information, such as AR image overlays. The peripheral zones are not occluded and remain directly viewable by the user. Thus, the projected images complete (or partially complete) the user's FOV of the external environment between the peripheral zones and may provide additional electronic information to the user.
