Fighting VR Sickness | VR UX | Intel Software


I’m Seth Schneider,
and this is VRUX. In this episode, we discuss
VR sickness, and some best practices to avoid it. VR sickness is the
uncomfortable feeling that can happen when your
eyes and your inner ear are telling your brain different
things about how you’re moving. Like motion sickness,
it is quite common, and can cause nausea,
and even vomiting. Modern VR systems have greatly
improved user experience, but sickness is still
a serious concern. Responsible developers
should consider these tips when creating VR
applications to ensure the highest level of immersion
and comfort for their users. Responded accurately
to users movements at all times, preferably
near typical human locomotion speeds. Strive for zero latency,
especially in head tracking. Take Intel innovator
Pedro Kayatt’s game, Apocalypse Rider. It’s a Mad Max
inspired motorcycle game that uses natural
body movements for control. This results in little
to no VR sickness. As you tilt your head, the
motorcycle moves left to right. Using the natural
movement of the player and matching the in-game
visuals is an effective way to reduce motion sickness. You should also maintain frame
rates equal to or greater than the hardware refresh
rate to avoid judder. 90 FPS is considered the
minimum comfortable frame rate. There are other tricks,
like re-projection, that can be used to
keep the experience smooth and comfortable, but
should be avoided if possible. Give users the opportunity
to calibrate stereo offset or enter pupillary distance. Avoid moving
objects that take up a large portion of the
user’s field of view to prevent feelings
of self-motion. Locomotion is a challenge. Make acceleration
infrequent and short, preferably instantaneous. In teleporting, provide adequate
visual cues to retain bearings and preserve
original orientation. These aren’t hard
and fast rules, but by following
these suggestions, you can cut down on VR
sickness, increase immersion, and make your VR experience
more comfortable. Thanks for watching. Please comment below with topics
