Virtual reality Glasses: An overview

A virtual reality headset is a head-mounted device that provides virtual reality for the wearer.

Virtual reality glasses

Virtual reality (VR) headsets are widely used with video games but they are also used in other applications, including simulators and trainers. They comprise a stereoscopic head-mounted display (providing separate images for each eye), stereo sound, and head motion tracking sensors, which may include gyroscopes, accelerometers, structured light system] etc. Some VR headsets also have eye tracking sensors and gaming controllers.

Features of VR Glasses

The lenses of the headset are responsible for mapping the up-close display to a wide field of view, while also providing a more comfortable distant point of focus. One challenge with this is providing consistency of focus: because eyes are free to turn within the headset, it’s important to avoid having to refocus to prevent eye strain.
The lenses introduce distortion and chromatic aberration, which are typically corrected in software. The lenses can also be adjusted dynamically to account for a user’s eyeglass prescription so that the user can use the headset without corrective eyeglasses.

Display quality and resolution
There are different optics and visual qualities that will affect how the individual views the image quality and how they experience the virtual world. The image will appear clearly due to the display resolution, optic quality, refresh rate, and the field of view.
Because virtual reality headsets stretch a single display across a wide field of view (up to 110° for some devices according to manufacturers), the magnification factor makes flaws in display technology much more apparent. One issue is the so-called screen-door effect, where the gaps between rows and columns of pixels become visible, kind of like looking through a screen door. This was especially noticeable in earlier prototypes and development kits, which had lower resolutions than the retail versions.

VR glasses

Virtual reality was used by Nintendo’s Wii game console by having the player use a controller to interact with the game of their choice, often being sports games. Soon after the release of Nintendo’s Wii, Microsoft’s Xbox received a full body reading system called Kinect and Sony’s PlayStation got a similar virtual reality device named the PlayStation Move. These gaming devices use virtual reality to control avatars within a game, where the player’s movements are copied by the avatar to complete the game. This means that the player is not truly engaged in the virtual reality world.

Pros and cons of Virtual Reality
Virtual reality glasses is a technology based on idea of immersing into the reality artificially not naturally. Finally VR becomes a reality but there are some Pros and Cons of it. Some of the major pros and cons are listed below:

Better than reality
Gives detail views
User have awesome experiences
Effective communication
Users gets addicted to the virtual world
Technology is still experimental
Training in VR environment is not real

Virtual reality glasses

Virtual reality Glasses play a major role in our society today. One of the ways is that pilots are now trained using virtual reality glasses before they are actually faced with real flight test. These glasses are not expensive to get, they are glasses you can afford.
