Virtual reality (VR) has changed the way we interact with virtual settings, allowing us to immerse ourselves in previously science fiction-only worlds. However, there has been one recurring issue: VR motion sickness, which can dissuade even the most eager users. Developers are now leading the charge in solving this problem, using creative approaches to make VR more comfortable and convenient for all.
VR motion sickness, also referred to as cybersickness or simulator sickness, is caused by a conflict between what one sees and what the body perceives. When your eyes register movement in an environment that exists virtually but not in the body, confusion ensues and the effects can be nausea, dizziness, and being disoriented. This sense of inconsistency is most realized in VR due to the heavy immersion.
Developers have been laboring on various technological advancements to combat these symptoms. One of them is the improvement of frame rates and decreasing latency. An increased frame rate (above 60fps) offers smoother graphics, eliminating the jerky motion that induces nausea. Low latency is also important since even minor delays between user input and visual response can worsen motion sickness.
Conventional VR movement, such as locomotion through the use of a thumbstick, can be one of the most prevalent motion sickness culprits. Developers are fighting this with other forms of movement:
Teleporting allows for leaping between positions within an area without moving between them at all, eliminating the feeling of travel that leaves players dizzy.
Vignetting or dynamic field-of-view adjustment slowly darkens screen borders during travel, reducing visual stimuli that cause individuals to become sick.
Natural Locomotion systems in which physical motion in the real world is converted into virtual motion, such as walking in place or on specialized treadmills, assist in synchronizing visual and vestibular cues.
Hardware-wise, there is a trend towards more intuitive and less disorienting hardware:
Eye tracking can dynamically adjust the interpupillary distance (IPD) for each user, providing a more precise and less taxing visual experience.
Haptic feedback equipment, including vests or gloves, provides tactile feedback that can ground users in the physical world, reducing sensory dissonance.
Programmers are also adapting software to be more user-friendly.
Adaptive VR environments that adapt to the user's comfort level, either slowing down the movement or modifying the visual perspective, are becoming more common.
Adjustable settings enable users to modify such things as movement speed, field of view, or the strength of visual effects to a personal level of comfort.
Training is a key to preventing VR motion sickness. Developers are providing tips and recommendations in VR applications:
It is beneficial to build "VR legs" similar to sea legs for mariners by instructing users to begin with brief exposures and work their way up to longer exposures.
To reduce symptoms, suggestions are given, such as blowing a fan across the user while in virtual reality or taking breaks at predetermined times.
The struggle against VR motion sickness is yet to be resolved, but one can't help but notice progress being made. Developers are not only attempting to develop technological means to solve this issue, but they are attempting to learn more about human biology as well so that experiences through VR would be more tailored to the individual. Future VR systems might include personalized settings based on user profiles, land earning how each user reacts to different situations in VR.
Community input has been priceless, with user information being actively collected by developers to refine their approaches. The cyclical process guarantees that every new iteration of VR technology is less susceptible to causing motion sickness, opening the doors for VR to become a mass-market solution for entertainment, education, and more.
In summary, VR motion sickness, which was previously a major stumbling block to take up, is being addressed methodically by developers through a combination of hardware advancements, software cleverness, and user training. As the solutions become increasingly sophisticated, VR might soon be accessed by more people without the hassle that used to come with it.
