Hi, everyone. I am going to introduce our work Tunnel Vision to you.
This is done with Hiroo Yamamura, Holger Baldauf, Dingding Zheng, Kanyu Chen,
Junichi Yamaoka, Kai Kunze at Keio University. Have you ever felt motion sickness?
It’s said one in three people are highly receptive to motion sickness.
Today we prepared some potential motion sickness triggers for you.
But, of course, we don’t want to be mean to let you feel sick. So, you can either
squeeze your eyes like this, to narrow your field of view. Or, you can use your hands
to make binoculars to narrow your field of view as small as you can. Or you can do both to minimize
the potential motion sickness symptoms. Like some of you may realize that
narrowed field of view contributes to eased motion sickness. Based on such
findings that related studies already achieved, we built this peripheral vision blocking glasses
to adjust your field of view dynamically. This is how our prototype functions.
As you see the interactive logic is, if the user moves their eyes, we assume that
the user feels well and wants to experience more visual stimuli.
So the switchable film will become clear to support so. On the other hand,
if the user feels sick, they can gaze at any place without moving their eyes for 3.5 seconds then the
film will become opaque removing the fast-moving scenery from their peripheral vision area.
We used three conditions to conduct our motion sickness score comparison. The first
is using a lensless frame, the second is using the dynamic glasses in its static mode, and the last
is using the dynamic glasses in its opaque-clear switchable mode. To control the visual stimuli,
we used this Oculus Quest 2 to build our virtual environment. We used a Latin square to decide in
which order the glasses are chosen. The way we set the lensless frame or the dynamic glasses is
like this figure indicates, luckily, since Quest 2 headset has an optional glasses spacer attached,
as a result, none of our participants reported feeling discomfort while wearing our glasses
and the headset at the same time.
Regarding visual stimuli, we used a VR game called Epic Roller Coasters
which we pre-installed in our Quest 2 headset. And in total, 19 participants joined our experiments.
Our experiments indicate that in the most cases wearing our prototype with its dynamic
clear-opaque On or Off resulted in less severe motion sickness symptoms
compared to wearing lensless glasses. In particular, in the cases of “Difficult focusing”,
“Fullness of head” and “Nausea”, we see statistically significant differences.
Besides, in the comparison of immersion, our results suggest
that there is no statistically significant difference between wearing a lensless frame
and wearing dynamic glasses, which means in conclusion our peripheral vision glasses
helped its users reduced motion sickness symptoms without impacting immersion.
Since these glasses can block current-work-unrelated
visual objects in your peripheral vision area, for instance, to deal with messy working environments
your colleagues come and go around you. So it can be expected to improve one’s concentration.
As well as to help people deal with real-life motion sickness. i.e. daily commuting conditions.
I see that’s it. Thank you very much.
