Intervention: Motion Reset for Healthy Subjects

Background: People use virtual reality (VR) technology to play games, socialize, work, or receive medical care. Some people have "cybersickness" after using VR. Cybersickness is similar to motion sickness. Symptoms include eye strain, nausea, dizziness, or headache. The symptoms are usually mild and go away after the person stops using VR. New software called Motion Reset is being designed to reduce symptoms of cybersickness during VR use. Objective: To see if Motion Reset software can reduce cybersickness in people using VR. Eligibility: Healthy adults aged 18 to 60 years. Design: Participants will have 1 clinic visit that will last about 1 hour. They will answer questions about how they are feeling. They will learn how to use the VR headset and the handheld game controllers. The study will be broken into 2 parts. For the first part, participants will be assigned to 1 of 3 groups: Group 1 will participate in a VR experience designed to prevent cybersickness. They will view screens and move around while they press buttons on a controller. Group 2 will participate in a VR experience that is not designed to prevent cybersickness. They will view screens and move around while they press buttons on a controller. Group 3 will have no VR experience. Participants will complete 2 questionnaires about their experiences in the first part of the study. For the second part, all participants will spend up to 20 minutes playing a commercial VR game called Jurassic World Aftermath. Every few minutes, they will be asked if they are experiencing discomfort. After playing the game, participants will complete 12 questionnaires about their experience.
