Regardless of advances in headset {hardware} and considerate software program design, virtual reality can nonetheless be a nauseating, dizzying, and sweaty expertise for some folks. From horrific rides on virtual roller coasters to alarming leaps withBeat Saber, you don’t have to speak to many individuals earlier than somebody shares a vomit-inducing expertise.
As a psychologist at York St John University, within the United Kingdom, I focus on how wearers react to VR, and so have been in a main place to watch the evolving approaches to the issue of cybersickness. Important progress in {hardware}—together with improved field of view, higher resolution, and reduced latency—haven’t utterly solved the problems. Software program designs like including digital noses within the show, visible consideration duties aimed toward redirecting the person’s focus, and enhanced visible realism have all proven promise within the lab however have confirmed frustratingly tough to duplicate persistently in the true world.
However a brand new wave of analysis might take the strain off engineers and builders and hand it again to the buyer. The analysis focuses on DIY strategies that enable customers to manage higher with VR. Listed below are three promising approaches.
#1: Stand Like a Flamingo
There are completely different theories concerning the underlying causes of cybersickness. One thought focuses on postural instability. In actual life, our brains work together with our vestibular and proprioceptive techniques, which give us a normal sense of the place our heads or our bodies are on the earth and create a physiological response that maintains our stability and stops us from falling over.
Sustaining your stability is more durable in digital actuality; the world seems to be prefer it’s transferring, however your physique doesn’t really feel it. It seems that your potential to stability is an effective predictor of your susceptibility to cybersickness. When researchers studied determine skaters, soccer gamers, and wushu fighters, for instance, those most proof against cybersickness had been the determine skaters.
So researchers in South Korea explored whether or not coaching folks to stability in VR, to offer them higher postural stability, would additionally cut back cybersickness. Contributors skilled for 3 minutes, twice a day, for 5 days. Within the management group, members merely stood and watched an expertise particularly chosen for its sickness-inducing motion patterns. Within the coaching group, members watched whereas they stood on one leg with their arms outstretched—the flamingo pose—for 30 seconds, adopted by 30 seconds of standing on two legs, repeated thrice.
On the finish of the week, each teams reported having fewer signs of cybersickness whereas viewing the coaching patterns. The members had been then proven new content material: a VR expertise about space exploration. Whereas the management group reported feeling virtually as sick as earlier than the coaching, those that had been standing like a flamingo reported a lot much less illness within the new expertise, with statistically vital reductions in disorientation. Studying to stability in VR meant they may higher deal with different VR experiences, not simply the one they’d develop into accustomed to.

#2: Lean In
If standing like a flamingo doesn’t sound interesting, then you’ll be able to strive being aware of the movement within the digital surroundings. This system entails postural alignment, and just like the flamingo pose, it builds on the concept postural instability is a crucial think about cybersickness.
In the event you’ve ever been on a roller coaster, you’ll have an instinct as to how this works. Because the curler coaster curves to the suitable, you oppose the movement by leaning to the left; because it heads to the left, you lean to the suitable. Whereas that looks like probably the most pure factor to do, it’s really unhelpful for motion sickness. You need to as a substitute lean “into” the flip—leaning proper when you’re going proper and left when you’re going left, simply as a motorcyclist does when taking a flip at pace.
Leaning into the movement seems to do the identical in VR. Researchers in the Netherlands and Greece teamed as much as discover this. Of their research, they opted for digital driving simulations on a Meta Quest 3 headset. What mattered was how intently the members aligned their our bodies to the implied movement. Those that maintained nearer postural alignment with the digital movement skilled considerably much less cybersickness, with the chance of cybersickness worsening with rising misalignment.
#3: Really feel the Vibes
Don’t fancy standing like a flamingo or leaning all over? Properly, how about vibrating the bones in your cranium? This answer requires urgent into service a sort of wearable tech that isn’t but generally out there—a vestibular stimulation machine, which sends little vibrations to the inside ear. Researchers are testing these gadgets to deal with seasickness and the signs of Parkinson’s disease. Firms like Otolith Labs are actually searching for approval to promote their merchandise past the analysis group. Research at the University of Newcastle, in Australia, examined whether or not the gadgets might ease VR cybersickness by decreasing the mismatch between vestibular cues and visible cues. In VR, your eyes are telling you that your physique is transferring, however your physique is satisfied that it’s not, and the mismatch is simply an excessive amount of for the thoughts to deal with. By vibrating the inside ear with a stimulator, the considering goes, folks might develop into extra tolerant of the mismatch.
Our potential to stability is an effective predictor of cybersickness.
To check the thought, the researchers made use of one of the vital sickening experiences you’ll be able to have in VR: a digital curler coaster. Contributors skilled the curler coaster with the vestibular machine connected to the mastoid bone behind the suitable ear, and set to no vibration, a low vibration setting, or the medium setting.
Contributors then rode the VR curler coaster for as much as quarter-hour, verbally reporting their ranges of nausea every minute. The management group had no vibration machine, one other group had the machine on a low setting, and a remaining group had the machine on a medium setting. The management group averaged 478 seconds within the experience earlier than they selected to finish the experiment, or employees ended the experiment due to excessive ranges of reported nausea. These with the low vibration setting lasted significantly longer, at 568 seconds, and people with the medium setting lasted 623 seconds.
Over to the Shopper
After all, none of those approaches is assured to work. They’re primarily based on pilot projects involving small numbers of members and awaiting replication. What makes them completely different from the previous is that anybody can strive not less than the primary two at house proper now, and there’s not an enormous hurdle to finally making an attempt out the third.
On the finish of the day, cybersickness has many doable causes and associations. Maybe future headsets will cut back the issue. Maybe well-designed VR experiences will assist, too. However probably the most promising path ahead might be a mixture of engineering options, design options, and user-initiated approaches—comparable to leaning in, standing like a flamingo, and vibrating these bones. Solely time will inform, however possibly at some point VR’s sickening curse might be damaged.
