Real VR glasses still cost an exorbitant amount of money. But virtual reality is closer than it seems. A simple inexpensive device can turn an ordinary smartphone, which allows you to play at Woo Casino Australia or watch Netflix, into VR glasses. Let’s try to figure out how smartphone VR glasses are made, what they are good for, and if there is any point in buying such a device.
VR glasses for smartphones are simple. They are a holder for your phone, attached to your head. A pair of lenses is installed inside, each of which focuses a different half of the image for “his” eye.
Accordingly, the smartphone screen is divided in half and two images are displayed – for the left and the right eye.
People have different vision, so most VR glasses have the ability to adjust the focal length of the lens.
On some models, the focal length can be adjusted for both lenses at the same time.
There are glasses where you can move back and forth on each lens individually. This will help if your eyes have different visual acuity.
Also, some glasses have the ability to adjust the distance between the lenses.
This is necessary, firstly, to take into account the interpupillary distance, which is different for all people. Secondly, by moving the lenses apart, it is possible to achieve a better image for smartphones with an elongated or, conversely, too wide screen. In the first case, you will need to open the lenses wider, in the second – to move them apart.
Matching Glasses to the Smartphone
Glasses should be selected according to their size. Each model has a range of supported smartphone diagonals. If your smartphone has a diagonal from 3.5″ to 6.3″, it will most likely be possible to fit VR glasses. But owners of smartphones with larger screens will have to find another way to immerse themselves in virtual reality.
Diagonal isn’t everything. The size of the frames around the screen and the aspect ratio of the screen can also affect the performance of VR glasses. If the image on your smartphone is larger than the VR glasses are designed for, you will only see part of the picture.
And if the screen is smaller, black borders will appear around the picture.
To completely rule out the possibility of such a discrepancy, read reviews and ask the owners of the device – perhaps someone has tested it with the same smartphone as yours. And the most reliable way is to go to the store and test your smartphone directly on the chosen model of VR glasses.
Not all smartphones can be fully used with VR glasses. For full immersion in virtuality, you need your smartphone to be able to track your head’s movements. To do this, it must be equipped with a gyroscope and accelerometer. However, these today are the majority.
The smartphone is controlled by its own touch screen. But what to do with it, if the screen (as well as the entire smartphone) is inside the VR glasses tightly closed. There are different options:
- The control is done with a cursor in the middle of the screen. To select the desired button, you need to point the cursor at it by turning your head, and to press it, you need to hold your gaze for a while. The method does not require any additional controls, but it isn’t supported in all apps and games. Moreover, the method isn’t suitable for dynamic games.
- Using the button on the body of the VR glasses. When you press it, the lever inside the glasses touches the screen. The way the button is used varies. In some applications, the button is selected by turning the head, and the button is already used to press it. In other apps, you control everything with just the button – single taps move through the menu, double taps press the selected button. The second option can help if your smartphone doesn’t have a gyroscope, but you want to somehow join the virtual reality. The method is suitable for dynamic games, but requires the button on the glasses and, again, must be supported by the app. Moreover, it isn’t always convenient to use this button. You have to hold the glasses with one hand all the time, putting your finger on the button.
- Sound volume control. Some models have built-in headphones with buttons for controlling them. This makes it easy to adjust the sound in any application. High-quality stereo sound greatly contributes to a deep immersion in virtual reality. All you need to do is connect the headphones in the glasses to your smartphone with a separate cable.
- A separate bluetooth controller. The most convenient option for games and apps that don’t support the above methods.
