VR refers to technology that entirely blocks your view of the real world and replaces it with an immersive, artificial environment. Cybersickness in virtual and augmented realityĬybersickness symptoms tend to be more intense with virtual reality and augmented reality. Everyday technology design can trigger this conflict between visual perception and physical experience. Your eyes receive information that tells them you’re moving even though your body isn’t. One prevailing idea, sensory conflict theory, hypothesizes that it’s from a mismatch of information perceived by the parts of the body that regulate vision and balance. There isn’t total agreement among researchers about why people experience cybersickness. The parallax effect, commonly deployed in many websites and games to give an illusion of depth, can lead to cybersickness symptoms. Parallax scrolling on websites, where a background image remains static while foreground content moves as you scroll, can also elicit these symptoms.

As it turns out, this was because it triggered cybersickness symptoms. For instance, Apple released a parallax effect on iPhone lock screens in 2013 that made the background image seem like it floated or shifted when a user moved their phone around, which many people found extremely uncomfortable. People can experience symptoms of cybersickness through everyday devices like computers, phones and TV. These issues can persist for hours and affect sleep quality. And several cybersickness symptoms, such as difficulty concentrating and blurred vision, overlap categories. Disorientation can manifest as dizziness and vertigo. Oculomotor symptoms, like eye strain, fatigue and headaches, involve overworking the nerve that controls eye movement. These symptoms fall into three categories: nausea, oculomotor issues and general disorientation. What is cybersickness?Ĭybersickness refers to a cluster of symptoms that occur in the absence of physical motion, similar to motion sickness. But I can assure you as a researcher in human computer interaction specializing in cybersickness that there are ways to anticipate and avoid feeling sick from your screens. These issues may seem like a necessary evil with the rise of work from home, remote learning and days spent endlessly scrolling online. Do you ever feel like the light of your computer screen is burrowing into your eyes and making your head pulse? Or feel dizzy or nauseous after looking at your phone? While you might think these sensations are just eye strain or fatigue from looking at your screen for too long, they’re actually symptoms of a condition called cybersickness.
