Augmenting Geometric Fields of View and Scaling Head Rotations for Efficient Exploration in Head-Mounted Display Environments
G. Bruder. Proceedings of IEEE Workshop on Perceptual Illusions in Virtual Environments (PIVE), page 9. (2011)
Abstract
Physical characteristics and constraints of today’s head-mounted
displays (HMDs) often impair interaction in immersive virtual environments
(VEs). For instance, due to the limited field of view
(FOV) subtended by the display units in front of the user’s eyes
more effort is required to explore a VE by head rotations than for
exploration in the real world.
In this paper we propose a combination of two augmentation
techniques that have the potential to make exploration of VEs more
efficient: (1) augmenting the geometric FOV (GFOV) used for rendering
the VE, and (2) amplifying head rotations while the user
changes her head orientation. In order to identify how much manipulation
can be applied without users noticing, we conducted two
psychophysical experiments in which we analyzed subjects’ ability
to discriminate between virtual and real head pitch and roll rotations
while three different geometric FOVs were used. Our results
show that the combination of both techniques has great potential to
support efficient exploration of VEs. We found that virtual pitch
and roll rotations can be amplified by 30% and 44% respectively,
when the GFOV matches the subject’s estimation of the most natural
FOV. This leads to a possible reduction of the user’s effort required
to explore the VE using a combination of both techniques by
approximately 25%.
