Kevin Arthur Paper -

- Field of vision spans approximately 200 degrees horizontally and 150 degrees vertically - current HMD's have FOV ranging from 30 - 70 degrees diagonally

- narrow field of view has been shown to degrade performance on navigation, manipulation, spatial awareness, visual search tasks, disrupts eye and head-movement coordination and perception of size and space

- wide FOV displays may not be correct in some situations - wite FOV will aggravate simulator sickness effects -- in particular due to vection and visual-vestibular mismatch

vection - illusion of self-motion - key indicator of simulator sickness

- well suited to maintaining self-orientation during locomotion - narrow field of view detracts from a persons ability to navigate through an environment effectively

-Alfano and Michel -- made subjects walk along a path while wearing goggles to restrict FOV (in particular peripheral vision)

Patricia L. Alfano and George F. Michel. Restricting the field of view: perceptual and performance effects. Perceptual and Motor Skills

-FOV of 12 or 40 degrees resulted in significant errrors.. less pronounced errors still present with FOV at 90 degrees

experiment - have people walk through virtual environment avoiding obstacles -test against people navigating same real world environment wearing goggles to mimic HMD

reaching is degraded by narrow FOV (misjudging distances) -- performed reaching task

narrow FOV tends to make objects appear nearer then they really are --> shrink environment around the user
