The person has a curious and engaged expression, capturing the sense of wonder that VR technology brings. The image conveys the excitement of exploring new worlds while addressing the topic of motion sickness in VR.

What causes motion sickness in VR

Virtual Reality (VR) is an artificial environment created with the help of software and presented so that it supersedes the user’s real-world environment. It is immersive, interactive, and visually compelling, providing an experience that is so convincing our brain believes it to be real. However, the journey into the virtual world isn’t always a smooth one. Many users experience a particular kind of discomfort known as motion sickness while using VR technology. This article will explore the phenomenon, its science, and how it can be managed.

This hero image depicts theconcept of sensory balance, which is crucial in understanding motion sickness in VR. It shows a split-screen view: on one side, a person's eyes are covered by a VR headset, engrossed in a virtual experience; on the other side, a close-up of the inner ear, highlighting its role in maintaining balance. This visual representation illustrates the disconnect between the senses, leading to motion sickness. The image aims to visually explain the scientific aspect of the phenomenon.

Understanding Motion Sickness

Motion sickness is a common condition that occurs in response to certain types of movement, whether real or perceived. It can happen on a car ride, on a boat, or even on a merry-go-round. However, it also happens in VR, known as “cybersickness.” Symptoms of motion sickness in VR include dizziness, nausea, and sometimes even vomiting. It’s similar to the motion sickness you might experience while reading in a moving car, but with VR, the symptoms can be more intense and immediate.

What causes motion sickness in Virtual Reality?

So, what causes motion sickness in VR? The answer lies in the discrepancy between what we see and feel. In the real world, our eyes, ears, and body work together to sense movement and maintain balance. When these senses don’t match up, our brain gets confused, leading to motion sickness. In VR, the situation is exacerbated because the virtual environment can make us feel like we’re moving when we’re not. This sensory mismatch can cause our brain to think we’re being poisoned, leading to symptoms of nausea and discomfort.

The science behind motion sickness in VR

The scientific explanation for motion sickness in VR is related to the vestibular system, a sensory system responsible for maintaining balance and spatial orientation. When you move in real life, your inner ear senses these changes and sends signals to your brain. In VR, your eyes see movement, but your inner ear doesn’t sense it. This conflict causes a sensory mismatch, leading to the symptoms of motion sickness. This phenomenon is known as “section” – the sensation of movement when stationary.

How VR technology is addressing motion sickness

To mitigate the issue of motion sickness in VR, technology developers are employing a range of strategies. One such approach is reducing the latency, the delay between the user’s actions and the response in the virtual environment.

Other solutions include introducing “teleportation” methods where users can move around the virtual environment without physically moving, thereby reducing the sensory mismatch. Developers are also researching ways to simulate physical movements in VR, like walking or running, to create a more immersive and less disorienting experience.

Tips to prevent motion sickness in VR

There are several ways to prevent motion sickness in VR. First, ensure you have a good quality VR headset with a high refresh rate and low latency. Taking regular breaks when using VR is important to allow your body to readjust to the real world. Additionally, starting with less intense VR experiences and gradually increasing the complexity can help your body adapt to the virtual environment. Finally, staying hydrated and avoiding heavy meals before using VR can also help minimize symptoms.

Case studies: Dealing with motion sickness in VR

Several companies and researchers are studying how to deal with motion sickness in VR. For instance, a team at the University of Waterloo is developing an AI system that predicts when a user might start feeling ill in a VR environment. Another case study involves Sony, the developer of PlayStation VR. They have published several patents that aim to reduce motion sickness by introducing a fixed reference point in the VR environment or adjusting the field of view.

Future prospects: Reducing motion sickness in VR

The future of VR holds exciting possibilities for reducing motion sickness. Researchers are exploring haptic feedback, where physical sensations are produced in response to virtual interactions. Moreover, AI and machine learning advances could lead to personalized VR experiences that adapt to the user’s comfort level, reducing the likelihood of motion sickness. The road ahead is promising but will require ongoing research and technological innovation.

Expert views on motion sickness in VR

Experts agree that motion sickness in VR is a significant issue that needs addressing. Dr. Steven LaValle, a leading scientist in VR technology, believes that understanding human perception and physiology is key to solving this problem. Others, like Dr. Thomas Stoffregen at the University of Minnesota, argue that motion sickness is not merely a technical issue but a fundamental human one. He believes that addressing it requires a better understanding of how we move and interact with our environment.

This hero image focuses on the future prospects and advancements in VR technology to reduce motion sickness. It features a collage-style composition: on one side, an individual wearing a VR headset, enjoying a seamless and comfortable VR experience without any signs of discomfort; on the other side, an array of futuristic VR equipment, including haptic feedback devices, personalized AI algorithms, and innovative VR environments. This image inspires optimism and highlights the ongoing research and innovation in the VR field.


While the issue of what causes motion sickness in VR is complex, the advancements in VR technology are promising. As we understand more about our perceptual systems and how they interact with VR, we can look forward to a future where virtual reality experiences are more comfortable, immersive, and accessible to all.

Frequently Asked Questions:

Why does VR cause motion sickness?

VR can cause motion sickness due to a disparity between what your eyes and body feel. This mismatch can confuse your brain, leading to symptoms of motion sickness.

How can I prevent motion sickness in VR?

You can prevent motion sickness in VR by taking regular breaks, starting with less intense VR experiences, staying hydrated, and avoiding heavy meals before using VR.

Is motion sickness in VR harmful?

While uncomfortable, motion sickness in VR is generally not harmful. However, if you continue to experience symptoms after removing the headset and resting, it may be best to seek medical advice.
