|Abstract / Description:||This paper describes the use of a large screen virtual environment|
to induce the perception of translational and rotational self-motion.
We explore two aspects of this problem. Our first study investigates
how the level of visual immersion (seeing a reference frame) affects
subjective measures of vection. For visual patterns consistent
with translation, self-reported subjective measures of self-motion
were increased when the floor and ceiling were visible outside of
the projection area. When the visual patterns indicated rotation, the
strength of the subjective experience of circular vection was unaffected
by whether or not the floor and ceiling were visible. We also
found that circular vection induced by the large screen display was
reported subjectively more compelling than translational vection.
The second study we present describes a novel way in which to
measure the effects of displays intended to produce a sense of vection.
It is known that people unintentionally drift forward if asked
to run in place while blindfolded and that adaptations involving perceived
linear self-motion can change the rate of drift. We showed
for the first time that there is a lateral drift following perceived rotational
self-motion and we added to the empirical data associated
with the drift effect for translational self-motion by exploring the
condition in which the only self-motion cues are visual.
