I am among the dedicated Apple users eagerly anticipating the release of the Vision Pro, despite its hefty price tag of $3,499. However, I have some concerns about potential motion sickness and nausea that could arise from using the device, which might hinder my ability to fully enjoy the immersive capabilities of this first-generation spatial computer.
Fortunately, it seems that Apple is taking significant measures to address this issue and ensure a seamless user experience. According to experts, the advanced technology integrated into the Vision Pro should deliver a lag-free AR/VR experience, minimizing the risk of motion sickness. And now, we have learned about another specification that aims to combat this problem.
The Vision Pro will incorporate a custom low-latency DRAM chip developed by SK Hynix. Although this may sound unexciting to some, it is actually one of the most intriguing features of the Vision Pro for me personally. The purpose of this chip is to facilitate fast and smooth rendering of the real world, a crucial factor in preventing motion sickness.
This information comes from The Korea Herald, which cites industry insiders revealing that SK Hynix is the exclusive chip supplier for the Vision Pro. Sources claim that SK Hynix will manufacture the custom dynamic random access memory (DRAM) chip, although the company has not officially confirmed its collaboration with Apple.
The custom DRAM chip is expected to support the R1 chipset introduced by Apple at WWDC 2023. This cutting-edge piece of Apple silicon is dedicated to processing data from the Vision Pro’s sensors, making it responsible for delivering the AR/VR experience and accurately tracking users’ eyes and hands. This integration further reinforces Apple’s commitment to providing a high-quality, comfortable, and immersive experience with the Vision Pro.
As an avid Apple enthusiast, these developments instill confidence in me that the Vision Pro will not only push the boundaries of augmented and virtual reality but also prioritize user comfort and well-being.
The R1 chip in the Vision Pro is designed to process continuous input from 12 cameras, five sensors, and six microphones, making it a crucial component for delivering an exceptional three-dimensional experience without any noticeable lag. The M2 chip, on the other hand, will handle visionOS and the overall app experience.
According to reports, the R1 chip is expected to process input with a remarkable lag of just 12 milliseconds, allowing for real-time data streaming to the displays. This speed is eight times faster than the blink of an eye, showcasing Apple’s commitment to achieving a seamless and immersive user experience. To further minimize delays, SK Hynix has developed a 1-gigabit DRAM chip with an increased number of inputs and output pins.
The custom chip integrated into the Vision Pro is referred to as Low Latency Wide IO, as reported by The Herald. Additionally, SK Hynix might have employed a specialized packaging method known as Fan-Out Wafer Level Packaging during the manufacturing process. This approach allows the DRAM chip to be attached to the R1 chip as a single unit, enhancing efficiency and performance.
All of these technical advancements appear promising on paper, particularly in terms of minimizing motion sickness and nausea while using the Vision Pro. In a recent BBC interview, expert David Reid expressed his confidence in Apple’s efforts to reduce motion sickness, citing their focus on reducing lag, minimizing delay, and utilizing high-quality displays. According to Reid, Apple has positioned itself as a leader in mitigating motion sickness among VR headsets.
Naturally, I will have to wait until the Vision Pro is released and tested personally to determine the extent of its effectiveness in preventing motion sickness. However, with Apple’s dedication to optimizing user experience and the positive feedback from experts in the field, it seems that my concerns may be alleviated.
