Patent attributes
Various technologies described herein pertain to a head mounted display device having a display with a central portion and a periphery portion. Graphical content can be displayed on the central portion of the display. The central portion can be a primary display that provides a field of view and displays the graphical content, and the periphery portion can be a peripheral display. The peripheral display can be positioned relative to the primary display such that an overall field of view provided by the primary display and the peripheral display is extended compared to the field of view of the primary display. Further, complementary content can be rendered based on the graphical content and caused to be displayed on the periphery portion (e.g., the peripheral display). The complementary content can include a countervection visualization viewable in a far periphery region of a field of view of human vision.
