Does virtual reality make you dizzy or nauseous? Research aims to nail causes and fixes | 24CA News
When Zubi Khan has pals over to play digital actuality video video games, it is commonplace for somebody to really feel a bit of sick to their abdomen.
“I’ve had friends come over where they would put a headset on and then, like, almost immediately they’d feel like that sense of vertigo and then they have to take it off,” Khan stated in a cellphone interview from a park close to his Toronto house.
“For me, I use a motorized wheelchair to get around, so I think part of that has made me kind of, like, immune to getting motion sickness because I’m used to being stationary while I’m moving,” stated the avid VR gamer and content material author for comedian and gaming CGMagazine.
“The only time where I’ll feel vertigo or feel kind of dizzy is if I haven’t used [VR] in a long period of time.”
Feeling sick after coming into a VR setting just isn’t unusual. Similar to movement illness, it is dubbed cybersickness.
People who get cybersickness could expertise a headache, vertigo (once you really feel what’s round you is transferring or spinning), disorientation, eye pressure or nausea.
One research revealed in June 2021 within the journal Nature that checked out predictors of cybersickness reported between 22 and 80 per cent of people that use VR could expertise it. The percentages diverse broadly, relying on the depth of the sport and the headset the individual was sporting.
What’s not as clear is who will get cybersickness and who will not.
But that is one thing Michael Barnett-Cowan, a researcher at Ontario’s University of Waterloo (UW), desires to determine as a result of the know-how is not nearly gaming. Virtual actuality can be utilized for different functions, corresponding to remedy or coaching.

The Morning Edition – Ok-W6:33Why do some individuals really feel sick after they go into digital actuality? This UW researcher explains why it is essential to know
Stepping into the world of digital actuality may be actually enjoyable or it could possibly make some individuals sick to their abdomen. Michael Barnett-Cowan is a professor within the division of kinesiology and well being sciences on the University of Waterloo and explains why some individuals expertise cybersickness whereas others don’t and why it is essential to analysis it.
Research into why some individuals get sick
Barnett-Cowan is an affiliate professor within the college’s division of kinesiology and well being sciences, and director of the Multisensory Brain and Cognition Lab. For their analysis, he and his staff collected knowledge from 31 individuals, and assessed how the themes perceived the orientation of vertical strains — or the subjective visible vertical.
“What we basically found in our research was that after being exposed to a fairly nauseating game in VR, people change the way that they process sensory information,” Barnett-Cowan stated.
The individuals got a activity earlier than taking part in VR to check how they use completely different cues for his or her sense of orientation on the earth. Then they’d play a sport in digital actuality for half-hour and be retested.
“Those that change the way that they process sensory information … those were the ones that didn’t get as sick,” Barnett-Cowan stated.
“Those that were really stubborn … so the way that they do this task before VR is the same as the way they do it after VR, those guys got fairly sick.”
Barnett-Cowan stated the researchers have been “pretty excited” to make that discovery, as a result of the findings of this research, which has been revealed within the journal Virtual Reality, might show to be “invaluable” for builders and designers of VR experiences.
William Chung is co-author of the research and a former UW doctoral scholar who’s now a postdoctoral fellow on the Toronto Rehabilitation Institute.
Chung stated their check considerably predicted the severity of cybersickness signs.
“By understanding the relationship between sensory reweighting and cybersickness susceptibility, we can potentially develop personalized cybersickness mitigation strategies and VR experiences that take into account individual differences in sensory processing and hopefully lower the occurrence of cybersickness.”
But Chung additionally cautioned this discovering is just a primary step and “there is still much to be explained.”

Marc Lanovaz, a professor on the Université de Montréal’s college of psychoeducation, helped develop a digital actuality app to convey a few of the day-to-day experiences individuals with autism face.
People fear VR will make them sick
Such analysis is sweet news for Robert Bruski, chief government officer and co-founder of Ctrl V, a digital actuality arcade that was began in Waterloo and has grown to incorporate areas in Ontario, Alberta, Delaware and Texas.
It issues Bruski when some individuals inform him they will not even attempt VR as a result of they’re afraid of getting sick.
“The vast majority of our content doesn’t induce nausea,” he stated, noting employees put the video games by means of a “very rigid 26-step vetting process” earlier than individuals use them.
It means most individuals can really feel assured placing on a headset to shoot orcs in Elven Assassin, slice up watermelon in Fruit Ninja or mess up an workplace in Job Simulator, he stated.
For Bruski, analysis that may assist everybody really feel extra snug coming into a digital actuality setting is nice, as a result of together with the avid gamers who use his arcade, corporations herald employees to discover ways to function heavy gear, colleges have college students use VR to study chemistry or astronomy, and seniors use the know-how to go to with gorillas or take a stroll in Paris.
But at the same time as researchers work on figuring out why some individuals expertise cybersickness, Bruski stated, that should not maintain anybody from attempting VR now.
“The motion sickness is determined by the game itself and specifically the locomotion in the game. So if you have a good virtual reality provider or if you are aware of what causes it, then you can completely eliminate that possibility.”
Khan stated it is fairly easy — for those who begin to really feel sick, take off the headset and wait a bit, however do not hand over.
When his pals take off the VR headset, “I’ll put it back on, and then they’ll watch me play, and then I’ll be having fun and we’ll try it again.”
