In any VR motion platform application we need a way to detect and cancel out platform movement versus actual rider movement. VR cybersickness typically occurs because our brains register an error between perceived body movement through our eyes, our inner ears and our proprioceptive systems. Discrepancy is often interpreted by our bodies as an early sign of poisoning, so our body reacts by making us nauseous. In a VR system there are many things that can trigger this response, but one of the hardest for VR developers to tackle is motion latency and accurate head movements versus platform motion tracking. No matter how clever a motion queuing algorithm is, if the system that it's being played through has too much latency or is too inaccurate people will still feel sick. The Raven 6DoF platform was developed to give VR experience designers the lowest latency and most accurate platform possible. This both reduces cybersickness and increases immersion. The player's View in VR is linked to their head movements, so if they turn their head to the left the view looks left if they pitch their head up the view looks up. It is important for the VR system to be able to differentiate a rider-induced movement of the head mounted display sensors and a platform-induced movement, also detected by those sensors. Most platforms accomplish this by placing a tracker on the chair and feeding information from that tracker into the simulation. This is a workable solution in some instances, but it can lead to issues with latency and jitter and it becomes entirely unworkable in any simulation where serious vibrations are being simulated. With the Raven platform however, the FPGA-based controller uses a forward kinematics model to calculate the exact location of the platform in space. This solution is far faster, far cleaner and far more efficient at helping VR developers build better solutions. Visit our website irisdynamics.com.

The YouTube video titled "Preventing Cybersickness featuring Raven-6DoF Virtual Reality (VR) Motion Platform Development Kit" is a detailed explanation and demonstration of how the Raven-6DoF platform developed by Iris Dynamics can help prevent cybersickness in VR applications. The video is 2 minutes and 17 seconds long and was published on June 9, 2023.
Cybersickness, a form of motion sickness that occurs in virtual reality, typically happens when there is a discrepancy between perceived body movement through our eyes, inner ears, and our proprioceptive systems. This discrepancy is often interpreted by our bodies as an early sign of poisoning, leading to nausea. One of the challenges for VR developers is motion latency and accurate head movements versus platform motion tracking.
The Raven-6DoF platform was developed to provide the lowest latency and most accurate platform possible, reducing cyber sickness and increasing immersion. The VR system needs to be able to differentiate between a ride or induced movement of the head-mounted display sensors and a platform-induced movement. Many platforms accomplish this by placing a tracker on the chair and feeding information from that tracker into the simulation. This solution is workable in some instances, but there are limitations. The text discusses issues with latency and jitter in simulations involving serious vibrations using the Raven platform. However, the FPGA-based controller uses a forward kinematics model to calculate the exact location of the platform in space, providing a faster, cleaner, and more efficient solution for VR developers.
The description of the video provides a link for viewers to access data sheets, CADs, and full technical specifications of the Raven-6DoF platform. It also includes links to the Iris Dynamics website, contact page, and LinkedIn profile for viewers who wish to learn more about the company and its products.
The transcript of the video provides a detailed explanation of the causes of cybersickness and how the Raven-6DoF platform can help prevent it.
