Abstract
Apparatus, systems, or methods for mixed reality are disclosed herein. An apparatus may include an optical structure, a display structure, and a controller coupled to the optical structure and the display structure. The optical structure may be controlled by a first electrical signal to act as a transparent glass to present a natural view, or to act as a magnifying glass to present a virtual view. The display structure may be controlled by a second electrical signal to act as an opaque display or a transparent display. In addition, the controller may control the apparatus to operate in at least an AR mode to interlace the natural view and the virtual view. Other embodiments may also be described and claimed.
