The headset must have only one input device. It doesn’t have to be a key. It can just be a hole for your finger to press on the display. If the device does have keys, they are usually little levers that push the display for you. What can you do with a single button? Select menu items or perform simple and rather slow actions in games. Some VR glasses do without buttons at all: just tilt your head toward the desired menu section and linger for a couple of seconds. Or turn your head to change the direction of movement in the game. For example, the aforementioned Gear VR has a convenient control system – a touchpad on the side, similar to a laptop trackpad. It does not work perfectly, but it replaces several functions at once: swipes, scrolling, pressing, holding, and the “Back” action.

Adjustment of interpupillary distance allows you to use the glasses according to the anatomical data of the user, and focus adjustment – comfortably use the helmet for people with imperfect vision.

The kit includes interchangeable lenses and a soft base that will extend the time of use. You should also pay attention to the mount that holds your smartphone during the game, and the ability to adjust the straps that secure the glasses to your head.

Almost all virtual reality headsets can be worn over vision correction glasses. Many models provide the ability to adjust the distance between your face and the lenses. Where this cannot be done, however, the glasses can put pressure on the bridge of your nose.

Virtual Reality Suit
This suit is supposed to track changes in the user’s entire body position and transmit tactile, temperature and vibration sensations and, when combined with a helmet, visual and auditory sensations.

Smells and Tastes
We have been working on odor synthesis for years, but the results are still far from being widely used. We cannot yet speak of any significant achievements in the field of gustatory sensations transmission.

Control devices
In order to interact with virtual environment we use special joysticks (gamepads, wands), that contain built-in position and motion sensors, as well as buttons and scroll wheels, just like a mouse. Nowadays such joysticks are more and more often made wirelessly.

The aforementioned information gloves and virtual reality suits can also be used as control devices.

They can be divided into three groups:

Glasses in which image processing and output is provided by a smartphone (Android, iPhone, Windows Phone). A modern smartphone is a high-performance device capable of independently processing three-dimensional images. Smartphone displays have a sufficiently high resolution. Almost every smartphone is equipped with sensors that allow to determine the position of the device in space.

2. glasses, in which image processing is provided by an external device (PC, Xbox, PlayStation, etc.). The external device must be high-performance, and the glasses are equipped with position sensors.
3. standalone virtual reality glasses (Lenovo Mirage Solo, with Google, Facebook’s Oculus Quest, Samsung Gear VR).
   Helmets are a major component of fully immersive VR, as they not only provide surround images and stereo sound, but also partially isolate the user from the surrounding reality.

MotionParallax3D displays
Such displays use the inherent human mechanism of volume perception – motion parallax. For this purpose, at any given moment of time for the viewer, based on his position relative to the screen, the corresponding projection of a three-dimensional object is generated. Moving around the scene, the user can look at it from all sides, with all objects of the scene will move relative to each other.

The phenomenon of parallax greatly enhances the perception of volume. Unlike 3D cinema and 3D TV, which only use binocular vision, MotionParallax3D technology allows the user to view a 3D scene from all sides, as if all the objects were real. Moving the viewer relative to the screen, which disturbs the volume effect in 3D cinema, in the MotionParallax3D system only enhances the effect.

A system that uses a parallax mechanism must pick up the smallest movements of the user’s head and track them with high speed and accuracy, so the brain does not detect distortions of the geometry of objects caused by a delayed change in the image. The delay should be no more than 20 ms, for interactive games no more than 11 ms.

These devices provide, as a rule, incomplete immersion, because they are played on displays and do not isolate the user from the environment.
