Virtual reality headset: how to use it?
How is it possible, that you can sit on the couch but feel as if you are in space? How could it be, that a small VR-headset flies you out of the real world? How to use virtual reality headset?
In this post, we will make a journey into the world of VR – take a look at the basics, learn how to use vr headset, and give you some tips on improving your experience.
Are you ready for it?
1. VR headset use: back to basics
The general goal of all the 3D-hardware out there is to eliminate the boundaries we have on TV and create a life size 3D environment.
You see the picture from your computer via a headset in either one of two ways.
- via an HDMI cable (if you have an HTC, Vive, or Rift);
- the smartphone is already slotted into the headset (as in Google’s Daydream Headset or Samsung Gear VR);
VR uses two feeds, one per every eye. Also, there are lenses between your eyes and pixels that reshape an image and create a stereoscopic 3D-view. By angling the 2D-picture, lenses so far mimic the way both of our eyes see the world (and they, as it turns out, do it a little bit differently).
Another reason why you get an image that realistic is changing its width. There is no need for a full 360-degree (no one’s viewpoint can reach that far), so 100-110 degrees will do the trick.
2. How to use a VR-headset for computer and smartphone?
Depending on your needs, you can buy a headset that works with a computer, and the one that interacts with the smartphone. Let’s take a look at both of them.
Those 3D-headsets require a strong powerful computer.
A good fit for gamers who want to enjoy their favorite games in 3D-mode.Here are some tips on how to use VR-headsets for computers:
- Before you start, download the drivers that are compatible with your 3D-hardware.
- VR-headsets for computer require a cable connection;
- After you’ve connected your headset, use your mouse to choose a movie or a game;
- Change display settings for each eye;
- Enjoy the high-quality stereo sound via headphones or PC-dynamics.
VR-headsets for smartphones:
Most headsets work by creating a 3D-image from a smartphone.
- Almost every company that produces 3D-headsets for smartphones has the app for managing them. You can download it for free and enjoy movies and games optimized especially for your headset;
- After you’ve downloaded all the stuff, all you do is just put your smartphone in a box, put your headset on, and enjoy the virtual reality;
- Some models also have joysticks available for ultimate gaming experience.
3. How to set up a VR headset?
Step 1. Understand what parts you need
Let’s see what you need to start your trip into the world of virtual reality.
- A headset itself.
- A smartphone or a computer. Most of the headsets use a smartphone screen and split image on it for left and right eye. The effect will be more impressive if you have the high screen resolution (1080 – fine, 1440 – gorgeous), and the phone is fast enough. Some of the headsets, however, work with a computer, so the choice is totally up to you!
Step 2. Focus your Lenses
To start adjustments, install the Cardboard Demo on your phone, enter the app, and scan the QR-code with the headset. The QR-codes sets the right field of view, interpupillary distance, and barrel distortion (in optics, the terms is used when straight lines start to curve out).
Actually, Google has a guide on how to use the Cardboard. If you want to manage the app easily, check it out!
Look into the headset and make sure, that image is right on your eyes’ level. If it’s not, loose the screws.
Also, you should work on the focus. Try focusing the lenses in and out till you have the perfect view.
Step 3. Some adjustments for the Inter-Pupillary Distance
The distance between your eyeballs is crucial to get the realistic 3D-image and prevent double vision. There are several ways to find your fit.
The fastest and the most accurate one is for those who already have an eyeglass prescription. You can find the IPD here (sometimes it might be marked as PD). Normally it is somewhere near 65 mm.
If you don’t have eyeglasses, there is no reason for frustration. IPD might as well be measured with a glass and a mirror. Personally, I used a pair of binoculars that have adjustable eyeball distance.
Put the binoculars on and tried to focus on the object that is far from you. Adjust your distance till you have a good view with no double vision.
Step 4. Generate a custom QR-code for the lens correction
Do you want a custom profile for your lens, IPD, and headset? Then set it up! Visit the Google Cardboard viewer profile generator website, follow some simple instructions – and voila, you have a custom QR-code.
That is all you need to know about VR-headsets to have a truly exciting and enjoyable experience of floating in the 3D-universe. Enjoy your ride!
