A simulation of low-field-of-view augmented reality (AR), using the estimated FoV of Microsoft's HoloLens (30 x 17.5 degrees). Filmed in a CAVE VR environment, using custom code to put "virtual blinders" on the user. The blinders create a truncated pyramid locked to the viewer's head, 30 x 17.5 degrees wide with the pyramid's top rectangle being 24" from the viewer's eyes.
The experience of this blindered setup closely matches what I experiences first-hand at Microsoft's Build 2015 conference, where I tried a HoloLens device.
The 30x17.5 degree FoV value is not officially confirmed, but based on measurements I took during my demo. The HoloLens' final FoV might turn out slightly different.
