To use the IPD tool for the Bigscreen Beyond 2, follow these steps:
1. Understanding IPD: First, it's essential to understand what IPD (Interpupillary Distance) is. IPD is the distance between the centers of your pupils. For VR headsets like the Bigscreen Beyond 2, setting the correct IPD is crucial for optimal viewing clarity. The Beyond 2 allows for independent adjustment of each lens, which is beneficial for users with asymmetric IPD.
2. Locating the IPD Tool: The IPD tool is a small hex tool provided with the Bigscreen Beyond 2. This tool is used to manually adjust the position of each lens independently.
3. Adjusting the IPD:
- Locate the small holes on either side of the headset's outer shell. These holes are where you insert the IPD tool.
- Insert the tool into one of the holes and twist it to adjust the lens position. You will see visible markings on the inside of the headset indicating the current IPD setting in millimeters for each lens.
- Repeat the process for the other lens, ensuring that both lenses are set to match your IPD measurements.
4. Determining Your IPD:
- Before adjusting the lenses, you need to know your IPD. You can use methods like a face scan provided by Bigscreen or apps like Eye Measure to determine your IPD. It's recommended to use your "far IPD" for VR headsets, as this setting provides the best visuals when viewing distant objects in VR environments[1][4].
- Alternatively, you can use a simple method involving a piece of paper with holes punched in it to measure your far IPD by aligning the holes with a distant object while switching between eyes[7].
5. Manual Entry in PC Software:
- After setting your IPD using the tool, you will need to manually enter this measurement into the PC software tool for the Bigscreen Beyond 2. This step is necessary because the headset does not have a sensor to automatically report the lens separations to SteamVR[2].
6. Testing and Verification:
- Once you've adjusted and entered your IPD, test the headset to ensure that the visuals are clear and comfortable. If necessary, make further adjustments until you achieve the optimal viewing experience.
By following these steps, you can effectively use the IPD tool for the Bigscreen Beyond 2 to achieve the best possible visual clarity and comfort during VR sessions.

What is the difference between near IPD and far IPD for VR headsets
In the context of VR headsets, the terms "near IPD" and "far IPD" refer to different measurements of the distance between the centers of your pupils, depending on how your eyes focus on objects at varying distances.
Near IPD
- Definition: Near IPD is the measurement of the distance between your pupils when you focus on objects that are close to you. This distance tends to be slightly smaller than your far IPD because your eyes converge inward when focusing on nearby objects.- Relevance to VR: For VR headsets, using your near IPD might not be ideal because VR environments often involve viewing distant virtual objects. Setting the IPD to a near measurement could lead to slight discomfort or visual distortion when focusing on distant virtual objects.
Far IPD
- Definition: Far IPD is the measurement of the distance between your pupils when you focus on objects that are far away. This distance is typically larger than your near IPD because your eyes are more parallel when looking at distant objects.- Relevance to VR: Far IPD is generally recommended for VR headsets because it aligns better with how you naturally view distant objects. Using your far IPD setting helps ensure that the virtual images are properly aligned with your eyes, reducing eye strain and improving the overall visual experience.
Key Differences
- Focus Distance: The primary difference between near and far IPD is the distance at which you focus. Near IPD is for close objects, while far IPD is for distant ones.- Visual Comfort: Using the correct IPD setting, especially far IPD for VR, can enhance visual comfort and reduce eye strain during extended VR sessions.
- Measurement: Near IPD is typically smaller than far IPD due to the convergence of the eyes when focusing on close objects.
In summary, for VR headsets like the Bigscreen Beyond 2, using your far IPD setting is generally recommended to ensure optimal visual clarity and comfort when viewing virtual environments.
How do I use the Eye Measure app to check my IPD
Using the Eye Measure app to check your IPD (Interpupillary Distance) involves a few simple steps. Here's a step-by-step guide on how to use it:
1. Download and Install the App:
- Go to your device's app store (e.g., Apple App Store for iOS devices or Google Play Store for Android devices).
- Search for "Eye Measure" or a similar app designed for measuring IPD.
- Download and install the app.
2. Prepare Your Device:
- Ensure your device is fully charged and has a clear, high-quality camera.
- Find a well-lit area with minimal glare to take the measurement.
3. Open the App and Follow Instructions:
- Launch the Eye Measure app.
- The app will typically guide you through a series of steps. Follow the on-screen instructions carefully.
- You might need to position your face within a frame or align your eyes with markers on the screen.
4. Take the Measurement:
- Look straight into the camera. The app will ask you to align your eyes with certain points or markers on the screen.
- The app may use facial recognition or other algorithms to detect the distance between your pupils.
- You might need to take a photo or allow the app to capture an image of your face.
5. Review Your IPD Measurement:
- After processing the image, the app will display your IPD measurement in millimeters.
- Take note of this measurement for future reference, especially when adjusting VR headsets.
6. Verify Accuracy (Optional):
- For critical applications like VR headsets, it's a good idea to verify the measurement using another method or by taking multiple readings with the app to ensure consistency.
Tips for Accurate Measurements:
- Use Good Lighting: Ensure the lighting is even and not too harsh, as this can affect the accuracy of the measurement.- Steady Positioning: Keep your head still and look directly into the camera to ensure accurate alignment.
- Multiple Measurements: Take multiple readings to confirm consistency and accuracy.
By following these steps, you can use the Eye Measure app to obtain an accurate measurement of your IPD for use with VR headsets like the Bigscreen Beyond 2.
