So the motion sickness is clearly one of the biggest flaws of virtual reality headsets, even if its impact has diminished in the new versions of the helmets and not everyone is necessarily affected, this thorn in the side of virtual reality is preventing it from moving forward. Headache, headache or a feeling of vomiting or too intense dizziness are issues that can only tarnish a VR experience.
But a clinic in Minnesota, called Mayo Clinique, who looked into this thorny problem, seems to have found an explanation for this evil, but above all a solution.
If we call this motion sickness, the clinical term is motion sickness. This motion sickness has no relation to the image latency or the refresh rate and even less to the resolution of the image, no, this motion sickness is produced for the exact same reason as sea sickness : the discomfort in the difference between visual perception and the vestibular system (the basis of the sense of balance), who do not experience the same things.
Thus, we see ourselves flying over the mountains, but our feet are on tiled floors, causing a perception disagreement, leading to motion sickness.
Mayo Clinic then offers lie to our vestibular system giving it the impression that it is moving. Placing two electrodes on the back of the user's neck and one on the forehead, adding a unique algorithm, the vestibular system will receive impulses informing the user that it is in motion.
A breakthrough that will be widely welcomed with open arms by VR headset manufacturers. For now Mayo Clinic is in partnership with vMotion for a hypothetical commercialization.
