Regardless of advances in headset {hardware} and considerate software program design, virtual reality can nonetheless be a nauseating, dizzying, and sweaty expertise for some individuals. 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 concentrate on how wearers react to VR, and so have been in a chief place to look at the evolving approaches to the issue of cybersickness. Vital progress in {hardware}—together with improved field of view, higher resolution, and reduced latency—haven’t fully solved the problems. Software program designs like including digital noses within the show, visible consideration duties geared toward redirecting the person’s focus, and enhanced visible realism have all proven promise within the lab however have confirmed frustratingly troublesome to copy persistently in the true world.
However a brand new wave of analysis might take the stress 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 here are three promising approaches.
#1: Stand Like a Flamingo
There are totally different theories concerning the underlying causes of cybersickness. One concept focuses on postural instability. In actual life, our brains work together with our vestibular and proprioceptive programs, which give us a common 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 tougher in digital actuality; the world seems to be prefer it’s transferring, however your physique doesn’t really feel it. It seems that your capability to stability is an efficient predictor of your susceptibility to cybersickness. When researchers studied determine skaters, soccer gamers, and wushu fighters, for instance, those most immune to cybersickness have been the determine skaters.
So researchers in South Korea explored whether or not coaching individuals to stability in VR, to offer them larger postural stability, would additionally scale back cybersickness. Individuals educated 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 have been then proven new content material: a VR expertise about space exploration. Whereas the management group reported feeling nearly 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 important reductions in disorientation. Studying to stability in VR meant they might higher deal with different VR experiences, not simply the one they’d turn out to be accustomed to.

#2: Lean In
If standing like a flamingo doesn’t sound interesting, then you may strive being aware of the movement within the digital atmosphere. This system includes postural alignment, and just like the flamingo pose, it builds on the concept that postural instability is a vital consider cybersickness.
If you happen to’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 seems like essentially the most pure factor to do, it’s really unhelpful for motion sickness. You need to as an alternative lean “into” the flip—leaning proper in the event you’re going proper and left in the event 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 growing misalignment.
#3: Really feel the Vibes
Don’t fancy standing like a flamingo or leaning all over? Nicely, how about vibrating the bones in your cranium? This resolution 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. Corporations like Otolith Labs at the moment are searching for approval to promote their merchandise past the analysis neighborhood. 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 pondering goes, individuals might turn out to be extra tolerant of the mismatch.
Our capability to stability is an efficient predictor of cybersickness.
To check the concept, the researchers made use of probably the most sickening experiences you may have in VR: a digital curler coaster. Individuals 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.
Individuals 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 trip 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
In fact, none of those approaches is assured to work. They’re based mostly on pilot projects involving small numbers of members and awaiting replication. What makes them totally different from the previous is that anybody can strive at the least the primary two at residence 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 potential causes and associations. Maybe future headsets will scale back the issue. Maybe well-designed VR experiences will assist, too. However essentially the most promising path ahead might be a mix of engineering options, design options, and user-initiated approaches—corresponding to leaning in, standing like a flamingo, and vibrating these bones. Solely time will inform, however possibly at some point VR’s sickening curse will likely be damaged.
