The first batch of the aGlass DK II has already sold out? Don’t worry—VR eye tracking accessories are here to bring you a new way to experience virtual reality.
Despite the cold winter, the excitement around the world’s first VR eye tracking accessory, the aGlass DK II, developed independently by Qixin Yiwei under the Vive X program, continues to grow. According to an official announcement on Qixin Yiwei's website, the pre-sale campaign for the aGlass DK II, which began on June 18 this year, was a huge success, and the first batch has been completely sold out. To better serve its customers, the sales channels for the aGlass DK II will be optimized and upgraded. More details can be found on the company’s official website. But what exactly makes the aGlass DK II so appealing that it has attracted so many developers and enthusiasts? Let’s take a closer look.
The aGlass DK II is the world’s first VR eye tracking accessory developed in-house by Qixin Yiwei. It offers features like gaze point rendering, eye-controlled interaction, and eye movement analysis, and is fully compatible with the leading HTC Vive VR headset. This innovative device brings a new level of immersion and efficiency to the VR experience. Let’s explore what makes it so special.
Gaze Point Rendering: Bringing the Virtual World to Life
One of the standout features of the aGlass DK II is its gaze point rendering technology. This function works by focusing high-resolution rendering on the central area of the user’s vision while reducing resolution in the peripheral areas. This not only reduces GPU load and power consumption but also minimizes latency and motion sickness in VR environments. In games like VR Funhouse, which combines multiple mini-playgrounds, this technology significantly lowers the hardware requirements without sacrificing visual quality.
For example, a game that typically requires a GeForce GTX 1080 SLI card to run smoothly can now run seamlessly on a GTX 1070, with minimal lag or discomfort. Additionally, gaze point rendering closely mimics the human eye’s natural field of view, enhancing depth perception and making the virtual experience feel more realistic and immersive.
Eye-Controlled Interaction: The World at Your Eyes
With the aGlass DK II, users can interact with VR environments using their eyes instead of traditional controllers. This makes navigation and selection more intuitive, as people naturally focus on what they want to interact with. Whether it’s selecting menus or interacting with objects, eye control adds a layer of realism and convenience to the VR experience.
Eye Movement Analysis: Understanding User Behavior
Beyond just tracking where the user is looking, the aGlass DK II can analyze eye movement data such as gaze trajectory, fixation points, and dwell time. This information is then visualized through heat maps and movement trails, helping developers understand user behavior and preferences. Such insights are invaluable for improving content design, user engagement, and overall experience in VR applications.
In terms of technical performance, the aGlass DK II boasts a 110° tracking field of view, a tracking speed of 100–380Hz, less than 5ms latency, and an accuracy of under 0.5°, placing it among the best in the industry. It also supports manual disassembly and custom lens options, offering flexibility for different use cases.
Beyond gaming and entertainment, eye tracking technology has wide-ranging applications. In sports, it can help quantify how eye movements correlate with athlete fatigue and mental state, aiding in performance analysis. In education, it can improve course design and student engagement by analyzing where learners focus their attention. Looking ahead, eye tracking is set to revolutionize fields like smart healthcare, mobile devices, advertising, autonomous vehicles, robotics, and even aerospace.
Joining the Vive X ecosystem has given Qixin Yiwei valuable resources and collaboration opportunities. As Huang Tongbing, founder and CEO of Qixin Yiwei, shared, “As a top team in Vive X, we’ve experienced the benefits of the VR ecosystem firsthand. We’ve built strong partnerships across the supply chain and are more confident than ever in applying eye tracking technology to VR. We believe that in the near future, this technology will bring even more exciting possibilities for developers and users alike.â€
