Virtual reality headsets are becoming very common these days. They allow us to immerse ourselves in virtual worlds. The problem is that they also cause headaches and nausea.
People often ask how to focus a VR headset.
Let’s find out!
How to Focus on VR Headset?
To focus on the VR headset, you need to adjust the distance between your eyes and the screen. The closer you are to the screen, the more details will be displayed on it. If you want to see a wider view of the world, then move away from the screen.
How Does a VR Headset Work?
A virtual reality headset is a device that allows us to replace our real world with a virtual one. It has a camera, gyroscope, controller, lens, etc., which work together to provide an immersive virtual reality experience.
The camera of the VR ensures all the movement of a user and connects the VR with computer systems software.
The accelerometer detects your movements in the virtual world. The controller lets you control your movements in the virtual environment.
The video is divided into two sections. One section appears on the computer monitor, and the other one is in your headset.
When everything works well, VR headsets perform flawlessly. However, if something goes wrong in any component, it may interrupt the entire functionality.
Lens blur is one of them.
Why Do VR Headsets Become Blurry?
There are several reasons for which your VR headsets’ lenses could be blurry. Among them, there is a reason that is easy to clean up.
If you don’t adjust the VR headset properly, then the lenses won’t be able to see clearly enough for you to use them.
If your camera has fallen or if its lens is damaged, then choosing the wrong picture size could result in an out of focus photo.
Here are some things that might be causing your VR headset to get blurry:
1. Dirty Lens
If you wear VR headsets too often, they may cause blurred vision.
With VR, the lenses tend to get dirty from your sweat and fog up most of the times.
To keep your VR headsets working well, you need to clean them regularly. If you don’t clean them often enough, they get dirty and oily.
2. Wrong Setup
When you buy a new VR headset for the first time, you need to set it up properly. If something doesn’t go right, then the VR won’t function correctly.
There might be some issues with VR headsets; blurry images are one of them
If Oculus Rift requires 72MHz for smoothness, but you choose to render at 60MHz, then you may see some jagged edges when using Oculus Rift.
3. Wear the Headset Incorrectly
If you wear the headset incorrectly when using it, one reason why you might see blurred images is because the lenses don’t perform well.
Then, after that, the blurry view will appear on your VR display.
You must adjust the Visor correctly if you want to use the headset. If you don’t, the lens won’t be able to focus clearly.
If you’re struggling to see through your VR headset, here’s the best solution for that problem.
4. Wrong Resolution of Videos
Selecting the correct screen size for your VR headset is very important. If your screen size is too small, you may not be able to see everything clearly.
If you choose 1080P resolution for your VR video, then the video won’t play perfectly because the lenses can’t change the resolution.
6. Cheap VR
Don’t expect the best VR experiences from a cheap VR headset; if you’re using a cheap and low quality VR headset, you won’t get the best VR experiences.
Some headsets give you a blurry 360-degree field of vision instead of an immersive virtual reality environment.
Here are some reasons why VR headsets become blurry.
Once we understand why something happens, it’s easy for our brains to come up with solutions.
5. Damaged Lens
A damaged Lense can cause blurry images. If your lens is damaged or cracked, it’s difficult to see clear images.
When using a VR headset with damaged optics, it won’t be able to focus perfectly, and blurry images will appear.
Initial Setup Adjustments for VR Headsets
Recently we bought an improved version of the Google Cardboard. It was cheaper than the original Google Cardboard, had a better designed inside, and offered some extra features.
However, there were no instructions for setting up the device, so we have included our setup procedure and what works best with the headset.
Step 1: Parts
1X Smartphone virtual reality headset ($20)
With the rise of virtual reality, we’re seeing a lot of new headsets hit the market. Some of them are quite expensive, so we are not surprised that people are trying to find ways to make VR cheaper. One of those ways is through cardboard headsets.
These are basically just plastic boxes with a screen inside. You put your phone into the box, and then you strap it onto your head. That’s pretty much it!
1X Super new fancy smartphone ($$)
A VR headset requires a high-end mobile device to function properly. You should test the performance of the device you want to buy by installing the Cardboard app and checking whether it runs smoothly.
Step 2: Focusing the Lenses
During setup, install the Google Cardboard app and scan the two-dimensional barcode for your headset.
Later steps cover generating a QR code for your devices. If they don’t already have one, leave them until later.
The QR codes refer to the lenses used by the headset which corrects for barrel distortion, the user’s visual angle, and interpupilary distance (IPD).
First, place the Google Cardboard headsets into the cardboard boxes. Next, insert the smartphones into the centers of the headsets. Finally, look for the lenses focusing mechanisms and learn how they work.
To check whether the lens’ alignment is correct, look at them from both sides. If they’re not aligned correctly, adjust them until the best image quality is achieved.
Step 3: Adjust the Interpupillary Distance (IPD)
The interpupillary (IPD) setting is important for creating a convincing 3d image and preventing double-sightedness.
You can determine your unique IPD by taking your current eyeglasses’ measurements and comparing them to the measurements listed in your eyeglass prescription. If they match up, then you know your unique IPD.
They will likely be between 65mm and 70mm long and are usually abbreviated to IPD or PD (for “interpupillary distance”). Measured several different ways, including by measuring them with a ruler and a handheld digital camera.
What worked best was using a pair of Binocular glasses with adjustable IPD settings. Using binocular glasses to focus on an object far away.
Adjusting the IPD spacing until you get a good three-dimensional image with no double-sightedness.
Now take the measurement between the two ends you focused through. This is your IPDS and will be used throughout this tutorial.
When setting the focus of the binoculars, make sure that both eyes are open. Then adjust the focus until the image appears sharpest.
Next, move the focus back towards infinity (as far as possible) and check if the image becomes blurry again.
Repeat these steps until the image remains clear throughout the entire range of focus.
Step 4: Lens Correction
To create a customized correction file for your headset, go into the Google Cardboard app on your computer. Then click Settings > Personalize > Adjustments > Add New.
Enter your IPD (interpupillary distance) into the box labeled “Inter-Lens Distance.” Then click “Generate Custom File.” Save the file somewhere safe.
Open the Cardboard app again and scan the QR code on the bottom right corner of the screen. Your phone should automatically launch the app and load the custom correction file.
Now that you’ve tried out the cardboard app, you should see that it looks 3D without any double vision. Make sure that the device is positioned correctly in the cardboard app.
Place the mobile device into the headgear so the vertical centreline is below the vertical dividing plate in front of the viewer and the horizontal center of the image, on your display, is aligned with the horizontal center of the lens.
If you adjust the viewer on your head so that your eye line matches up with the camera, you might see some fringe colors as your eye moves out of alignment with the camera.
