Greater than 7 degrees is rare without head movement greater than 12 degrees
is considered the typical limit. References are from the HMD handbook.
A head mounted display with a field of view greater than 26 degrees is
virtually useless as a computer data display as it is unbearably
uncomfortable to use.
