VR gameplay, VR headsets

You will probably agree VR is the Future

If you are going to buy a virtual reality viewer, the first thing to take care of is the Picture Quality. Modern headsets are either equipped with their displays or use smartphone screens. The picture quality mostly depends on the resolution, i.e. the higher the decision is, the better the picture a user sees. If a headset uses the phone display, the resolution will be the one supported by the smartphone. On the other hand, if you have a viewer with a built-in screen, you should take the aspect ratio into account. It is recommended to choose a wide-screen display with the aspect ratio of 16:9 and HD resolution. These features define the refresh rate, which is vital for ensuring a smooth changing of frames in dynamic scenes. Another critical parameter is the viewing angle or the field of view. The broader it is, the more objects you can see at the same time.

You will probably agree that seeing an excellent picture accompanied by a poor sound doesn’t give you a taste of reality. Specific headsets have built-in audio systems, while others use the speakers of smartphones. If the device has built-in speakers, they split the audio signal and create a stereo effect. To improve the audio quality, you can use other earphones. Some headphones support the 5.1 surround sound providing you with impressive 3D audio effects. Additional conveniences of virtual reality viewers can include motion sensors such as accelerometer, gyroscope or proximity sensor. All these sensors make a VR gameplay genuinely realistic and fun. If your device uses a smartphone, you should find out whether your phone has the necessary sensors. It is also recommended to look at the controls that might include a sensor panel, built-in keys or buttons or external controller units. It should be mentioned that flagship models feature the adjustment of the focus distance, approximation, or sharpness; all of them improve the picture quality. The lenses on the most advanced models can be adjusted individually for people suffering from myopia or presbyopia. Usually, the headset is connected to the smartphone via a USB port or to a TV set or an external monitor through the HDMI slot.

Finally, we would like to clarify the meaning of such criteria as the Compatibility and Comfort. Planning to purchase the virtual reality headset with a smartphone as the source of the signal, you should find out what the headset supports screen size range. The majority of VR headsets are compatible with phones with the displays from 4” to 6” wide. If a headset needs to be connected to a personal computer, you should also be sure that it’s compatible with the PC’s operating system and hardware. For the ultimate comfort, the design of virtual reality headsets allows adjusting them to almost all possible head sizes and shapes. Apart from physical positioning, the convenience also depends on the weight of a VR headset. If you wish to enjoy the virtual reality for a long time without any harm to your health, you should use the lightweight models.
