From page 13...
... Although it's not yet possible to display real-time VR content that's indistinguishable from reality, it is already possible to produce an experience referred to as "presence" -- the sense that a person has, in fact, been transported somewhere else. This transportation isn't always conscious: a person experiencing presence may logically know they're wearing a headset, but have measurable reactions to virtual objects or threats, such as fear in response to virtual heights.

... The blending of real and virtual content can augment everything from daily life, such as virtual name tags or line-item reviews superimposed on a restaurant menu, to complex specialized tasks, such as the overlay of MRI data directly onto a patient in an operating room.

From page 15...
... The reflex actively destabilizes the view presented on a head-mounted display, causing it to slide across the retina and blur as VOR makes the eye counterrotate. Visual Artifacts from Displays Judder Judder is the blurring effect caused by the VOR and a static head-mounted display.

From page 16...
... The global display adds significant latency: rather than displaying pixels immediately, all pixels wait until the last one to arrive before illuminating. With rolling displays, if users move their eyes during the display update, the image appears to distort or shear depending on the direction of movement.
