10. Opening remarks and an introduction to vection
Takeharu Seno (Kyushu University)
Coherent motion over a large area of the visual field induces an
observer’s self-motion perception, i.e. vection. I will present a
basic introduction to vection research, providing a brief review of
previous vection investigations. I will introduce four speakers who
are two young Japanese and two top researchers of vection in the
world.
(Two vection studies by younger generations)
11. Self-motion Perception by wind
Kayoko Murata, Masami Ishihara, Shigeru Ichihara (Tokyo Metropolitan University)
We examined whether a feeling of self-motion would occur when feeling
wind on the skin accompanied by vestibular motion. Participants
perceived the strongest self-motion in the vestibular motion and wind
condition. Wind from the front induced stronger self-motion than other
directions. We divided the face into upwards and downwards from the
center of the maxillary division. We compared the upper part with the
lower. When the upper part of the face was masked, all indexes
indicated a decrease in self-motion. Therefore, this result suggests
that the upper part and lower part of the face might use different
information processing systems.
12. Examining the cause of inverted vection using
expanding/contracting random-dot patterns
Yasuhiko Saito, Kenzo Sakurai (Tohoku Gakuin University)
The "inverted vection" is self-motion perception in the same
direction as a foreground motion induced by the slowly translating
foreground with an orthogonally moving background (Nakamura & Shimojo,
2000). We extended their studyto (1) investigate whether the inverted
vection in depth occurs or not, and to (2) reexamine their claim that
the mis-registration of eye movement by suppression of optokinetic
nystagmus (OKN)induced by the foreground pattern causes the inverted
vection (Nakamura & Shimojo, 2003).For these purposes, a
non-translational expanding/contracting visual stimulus pattern
asaforeground was used to prevent thetranslational OKNin Experiment
1and 2. And alsoanother non-translationalrotating visual pattern was
used as a background to eliminate the all possible translational OKNin
Experiment 2.
In Experiment 1, observersworea shutter goggle for stereoscopic
vision, and viewedstimulion a screen in 120 cm viewing distance.
Afixation cross was always presented inthe center of screensurface.The
background pattern was perceived to be 15cm fartherthanthe screen
withrightward translatingrandom-dotsat a constant speed of 25
deg/s.The foreground pattern was perceived to be 15cm nearerthan the
screen with expanding/contractingrandom-dots at 5constant
accelerations (0.056, 0.223, 0.893, 3.571, 14.286 deg/sec2). Both
foreground and background patterns were presented in the experimental
condition. Only the foreground pattern was presented in the control
condition. Observers performedkey-press to report their
perceivedforward/backward self-motion, and the reported direction
andduration of self-motion were recorded.In experimentalcondition,
observers reportedinvertedvection when the foreground random-dots
expanded/contracted slowly, and they reported ordinary vection when
the random-dots expanded/contracted fast.In control condition, the
duration of the self-motion sensation varied linearly with the speed
of stimulus motion. The faster motion induced the stronger self-motion
sensation in the direction opposite to the pattern motion.
In Experiment 2, methods were the same as in Experiment 1 except that
a rotatingclockwise/counter-clockwise random-dot pattern was used as
the background at a constant angular velocity (25 deg/s). Observers
perceivedthe inverted vection when the foreground pattern
expanded/contracted slowlyin experimental conditionwhile they
reportedthe ordinary vection in control conditionassame as the results
of Experiment 1.
We concludethat (1) the inverted vectionin depth occurs, and (2) there
must be some factor for the inverted vection in depth other than the
mis-registration of eye movement by suppression of translation OKN.

13. Using Virtual Reality to study multi-modal and higher-level
contributions to selfmotion illusions ("vection")
Bernhard Riecke (Simon Fraser University Surrey)
There is a long tradition of investigating self-motion illusions
induced by rotating or translating visual stimuli ("circular/linear
vection"). Other modalities can also induce vection or contribute to
visually induced vection, but have received considerably less
attention in the literature. Here, I will focus specifically on
non-visual and multi-modal contributions and interactions to vection.
Apart from vection being arguably one of the most compelling and
embodied illusions, vection is also interesting from a fundamental
research perspective, in particular in the context of investigating
cue integration: In a vection-inducing situation, there is always a
(more or less noticeably) cue conflict between some cues indicating
self-motion (e.g., a moving visual or auditory stimulus) while others
indicate stationarity or a lack of acceleration (e.g., tactile,
kinesthetic, and vestibular cues from sitting on a stationary chair).
From a more applied perspective, we are investigating how self-motion
illusions could be utilized to improve self-motion simulations and
human performance in virtual environments, in an attempt to reduce the
need for costly physical motion of the observer.
14. Stereomotion, changing-size, jitter and eye-motion based effects on vection
Stephen Palmisano (University of Wollongong)
Vection is a term typically used to refer to visually induced
illusions of self-motion. Over the years my colleagues and I have
shown that many previously overlooked visual consequences of
self-motion – stereoscopic motion, local changes in optical size,
viewpoint jitter/oscillation and eye-movements – all play important
roles in vection. These findings disprove long held assumptions that:
(i) visual self-motion perception is based solely on the optic flow
presented to a single eye; (ii) dot motion displays convey all of the
important visual information for self-motion; and (iii) visually
simulated self- acceleration prevents/destroys vection. Recently, we
have also examined how vection is altered by eye-movements. For
example, we have shown that superimposing a laterally moving fixation
point onto a radial optic flow display can dramatically enhance the
experience of vection in depth. Such findings suggest that common
pursuit eye- movement errors play important roles in vection
induction. In fact, in some situations, eye-movement patterns might
even serve as objective indicators of vection.
