Summary: | Size and distance perception in Virtual Reality (VR) have been widely
studied, albeit in a controlled laboratory setting with a small number of
participants. We describe a fully remote perceptual study with a gamified
protocol to encourage participant engagement, which allowed us to quickly
collect high-quality data from a large, diverse participant pool (N=60). Our
study aims to understand medium-field size and egocentric distance perception
in real-world usage of consumer VR devices. We utilized two perceptual matching
tasks -- distance bisection and size matching -- at the same target distances
of 1--9 metres. While the bisection protocol indicated a near-universal trend
of nonlinear distance compression, the size matching estimates were more
equivocal. Varying eye-height from the floor plane showed no significant effect
on the judgements. We also discuss the pros and cons of a fully remote
perceptual study in VR, the impact of hardware variation, and measures needed
to ensure high-quality data. |
