Enhancing User Comfort in the Metaverse

Recent studies indicate that 40% to 70% of Metaverse users experience physical discomfort, such as dizziness, eye strain, and nausea, during virtual experiences. This phenomenon is commonly known as "Cybersickness" or "VR Sickness." We are dedicated to researching reliable methods to measure these symptoms and developing effective strategies to mitigate them to create a comfortable virtual environment for everyone.
