The actual problem that the patent is intended to solve, for those who'd rather comment than RTFA:

"A problem with HMDs, primarily HMDs that are not of the see-through kind, is that the image on the display in front of each eye fills the central but not the peripheral field of view of the user. Consequently, the visual experience is similar to looking into a box or tunnel having a small screen at a distance. Peripheral vision is good at detecting motion and as a result, occluded peripheral vision in HMDs can cause a user to experience motion sickness symptoms after some time. Thus, whereas existing HMDs may work well for their intended purposes for short periods of time, there is a continuing need for improved HMDs that provide enhanced long-time visual experience for the user."

Their solution also only involves projecting a solid colour into the peripheral view. Actual peripheral view for our eyes can make out details and shapes, so it is not to emulate vision but to "reduce fatigue."

Not so, the patent describes various options for dealing with peripheral vision, including projecting blurred shapes corresponding with the environment, 'frames' and solid colours.
