The Bigscreen Beyond 2e and the Valve Index are two distinct VR headsets with different approaches to eye tracking.
Bigscreen Beyond 2e Eye Tracking:
- Integrated Solution: The Beyond 2e includes a built-in eye-tracking suite, which Bigscreen claims is "the world's smallest" with sensors the size of a grain of sand. This technology is designed to be efficient, running on the GPU rather than taxing the CPU like some other PC VR eye-tracking solutions[1][3].
- Functionality: Initially, the primary use of eye tracking in the Beyond 2e is for driving avatar's eyes in VRChat. While it does not support foveated rendering at launch, this feature is planned for later development. Bigscreen is working with Valve and Nvidia to implement foveated rendering, which could enhance performance by focusing rendering resources where the user is looking[1][3].
- AI-Powered Computer Vision: The eye-tracking system in the Beyond 2e utilizes AI-powered computer vision for low-latency and privacy-focused tracking, integrating with platforms like VRChat[3].
Valve Index Eye Tracking:
- Lack of Native Support: The Valve Index does not come with native eye-tracking capabilities. However, users have developed DIY solutions using open-source projects like EyeTrackVR, which leverage hardware components such as OmniVision cameras and IR LEDs[4].
- DIY Solutions: These community-driven mods allow users to add eye tracking to the Valve Index, often using 3D printed parts and off-the-shelf components. While these solutions are innovative and functional, they require technical expertise and are not as streamlined as integrated systems.
- Community Development: The EyeTrackVR project, for example, provides a framework for users to implement eye tracking on the Valve Index. It involves a basic Python OpenCV pipeline and can be integrated with social VR apps like VRChat[4].
In summary, the Bigscreen Beyond 2e offers a built-in, compact eye-tracking solution designed for efficiency and integration with VR platforms, while the Valve Index relies on community-driven DIY solutions that require more technical setup and customization.

How does the field of view of Bigscreen Beyond 2 compare to that of the Valve Index
When comparing the field of view (FOV) of the Bigscreen Beyond 2 and the Valve Index, we can look at the specifications and how they impact the user experience.
Bigscreen Beyond 2 Field of View:
- FOV Specifications: The Bigscreen Beyond 2 offers a horizontal field of view of approximately 120 degrees. This is relatively wide compared to some other VR headsets, providing users with a more immersive experience.
- Visual Quality: The Beyond 2 is designed to deliver high-resolution visuals, which, combined with its wide FOV, enhances the sense of presence in virtual environments.
- Design Focus: Bigscreen emphasizes the importance of a wide FOV for creating a more natural viewing experience, which is crucial for social VR interactions and immersive gaming.
Valve Index Field of View:
- FOV Specifications: The Valve Index features a horizontal field of view of about 130 degrees, making it one of the widest among consumer VR headsets available. This wider FOV contributes to a more realistic and engaging experience.
- Visual Quality: The Index is known for its high-resolution displays and advanced optics, which, when combined with its wide FOV, provide users with a highly detailed and immersive visual experience.
- Design Focus: Valve designed the Index with a focus on delivering the best possible VR experience, including a wide FOV that simulates peripheral vision more closely than narrower headsets.
In summary, while both headsets offer a wide field of view, the Valve Index has a slightly wider FOV at 130 degrees compared to the Bigscreen Beyond 2's 120 degrees. This difference can impact the sense of immersion and realism, with the Valve Index potentially offering a more expansive view of virtual environments. However, the Beyond 2's focus on compact design and efficiency also makes it appealing for different use cases.
What are the main differences in lens technology between Bigscreen Beyond 2 and Valve Index
The Bigscreen Beyond 2 and the Valve Index utilize different lens technologies, each designed to optimize the VR experience in distinct ways.
Bigscreen Beyond 2 Lens Technology:
- Compact Design: The Beyond 2 features a compact design with lenses that are optimized for a smaller form factor. This compactness is achieved without compromising on visual quality, making it suitable for users who prefer a more portable VR solution.
- Resolution and Clarity: The headset offers high-resolution displays, which, combined with its lens technology, provide clear and detailed visuals. The focus is on delivering a crisp and immersive experience within a more compact package.
- Eye Relief and Comfort: The design also emphasizes comfort and eye relief, ensuring that users can wear the headset for extended periods without discomfort. This is important for prolonged VR sessions, especially in social VR environments.
Valve Index Lens Technology:
- Advanced Optics: The Valve Index boasts advanced optics with custom-designed lenses that are optimized for a wide field of view and high-resolution displays. These lenses are designed to minimize distortion and provide a sharp image across the entire viewing area.
- Dual-element Lenses: The Index uses dual-element lenses, which help to reduce chromatic aberration and improve image clarity. This results in a more realistic and immersive visual experience.
- Interpupillary Distance (IPD) Adjustment: The Index allows for a wide range of IPD adjustments, ensuring that users can customize the fit to match their individual eye spacing. This feature is crucial for achieving optimal visual clarity and comfort.
