Peripheral display for head mounted display device

A peripheral display system, comprising:

• a peripheral display, wherein:
• the peripheral display is attachable to a head mounted display device;
• and
• when attached to the head mounted display device, the peripheral display is positioned relative to a primary display of the head mounted display device such that an overall field of view provided by the primary display and the peripheral display is extended compared to a field of view of the primary display;
• at least one processor;
• and
• memory that comprises computer-executable instructions that, when executed by the at least one processor, cause the at least one processor to perform acts including:
• rendering complementary content based on graphical content displayed on the primary display;
• and
• causing the complementary content to be displayed on the peripheral display.

A method of controlling operation of a head mounted display device, comprising:

• receiving motion information that specifies actual motion of a user of the head mounted display device;
• detecting a mismatch between the actual motion of the user specified by the motion information and virtual motion included in graphical content displayed on a central portion of a display of the head mounted display device;
• responsive to detecting the mismatch, creating an optical flow that moves in a direction of the virtual motion included in the graphical content;
• and
• causing the optical flow to be displayed on a periphery portion of the display of the head mounted display device.
