What is modern virtual glasses, and how did they manage to conquer the mass market and gain fans around the world so quickly? These are modern devices that allow the user to plunge into the world of virtual reality and experience the whole spectrum of emotions. After all, with the help of glasses, a person gets into conditions in which, theoretically, he could not be in real life.
Principle of operation
Virtual glasses are made of high quality cardboard or plastic. They can connect to a personal computer, smartphone or game console. On sale there are independent headsets that work autonomously. All virtual reality gadgets are similar and consist of a housing, lenses, a display (one with a partition or two separate), a gyroscope and controllers.
How do modern virtual glasses work? By transmitting the signal from spatial sensors and displaying the image on the screen, the user can interact with and / or manage virtual reality objects. In this case, all gestures and movements of a person are read in real time. For example, a gyroscope is needed to better orient the user in the virtual world and to accurately track all head turns. Each eye of the user sees a separate picture, due to which the effect of a three-dimensional image is achieved. The housing has special anti-fogging holes, as well as a USB cable or Bluetooth for connecting to a phone or computer. Sound is transmitted to speakers or headphones.
Glasses for smartphone You can synchronize with your computer using a special application. For example, Trinus VR. To do this:
- Download the Trinus VR application from the Play Market and install it on your phone;
- Install Trinus VR Server on a personal computer;
- After starting the applications, turn on the Fake Roll function on the computer to display the picture on the phonep;
- Change the screen resolution to 980 x 1020 pixels;
- Select the display screen "in the window";
- Connect the phone to the computer (preferably through a standard USB cable). For the game it is more convenient to use a mouse or keyboard.
You can use virtual reality glasses to view 3D images and games, games and applications marked VR (virtual reality). On Youtube, for example, they created a section for viewing panoramic videos. You can watch movies and TV shows, concerts, chat with friends. Access to virtual content is provided by the Oculus or Samsung VR applications. A qualitatively new level of immersion in all kinds of games for everyone is provided with their help. A username or email (if logged in with Facebook) is constantly requested to log in to Oculus.
You can check whether the phone is compatible with VR applications as follows: after installing the application, the user should turn the smartphone around him and make tilts up and down. If the picture on the display unfolds after the smartphone vertically and horizontally - the phone is compatible.
Virtual reality glasses become training, because interactive reality makes it possible to simulate a training environment. For example, the Volkswagen Group has already announced its intention to train employees with various virtual skills using virtual reality. In the United States, virtual reality technology is planned to be used in teaching. With the help of VR, they are even going to teach doctors how to perform operations!
Tips Before Buying A VR Headset
Virtual reality glasses that will be used in tandem with a smartphone should be selected based on 4 important parameters:
- Display size.
- Weight.
- Characteristics of the smartphone.
- The design of the glasses.
- Viewing angle.
Standard glasses work with phones of different sizes and operating systems. But it is desirable that the diagonal of the smartphone was at least 4.5 inches, with Q HD FullHD-resolution. Support for the Android operating system - from 4.1, Windows from - 7.0, iOS - from 6.0.
The use of virtual reality glasses should not cause discomfort. Therefore, the lighter the virtual helmet, the more convenient it is. Smartphones are also welcomed more than 200 grams. A viewing angle of 75 to 110 degrees will be optimal.
An important parameter is the interpupillary distance. In some models, it is configured for the owner, and somewhere - they choose independently. You should also check the availability of interchangeable lenses in the kit, the quality of the phone mount and belt adjustment.
If a gamer who has a gaming computer with a powerful processor is puzzled by buying a VR headset, it makes sense to opt for an Oculus or HTS helmet. Moreover, users note that the optics in Oculus are better, and the controllers are more convenient than in HTS. In addition, Oculus is cheaper and offers users a number of its own exclusive games.
For Sony PlayStation 4 and Sony PlayStation 4 Pro consoles, PlayStation VR with a catalog of exclusive games in addition is suitable.
“Buying Oculus or HTS helmets for outdoor games is justified if the user has a large apartment and is spacious enough in the game room. After all, devices track the player’s movement up to 20 square meters.
