It may sound strange to some, but the concept of virtual reality isn’t new. It has a long history, but it wasn’t until recently that itbecame popular among millennials. When talking about virtual glasses in general, the story about these amazing glasses started in the 1930s when Stanley G. Weinbaum shared the idea in one of his short stories – Pygmalion’s Spectacles. This story touched on the idea of using a pair of glasses that can let the user experience a fictional world through holographic, touch, smell and taste. Well, the truth is that virtual reality, or simply known as VR, has turned from fantasy to reality in just a short period of time.
VR technology is all about creating a realistic 3D image or environment. Thanks to this option, the human eye can perceive this as reality, and can even interact in some realistic ways. Nowadays, we have easy access to such devices as they are available in the form of vr goggles. These headsets are created of hardware and software and they make it difficult to differentiate fantasy from reality. This renders VR different from AR – augmented reality.
Nowadays, one can choose from many versions of vr goggles from top tech brands. The first thing to know about VR headsets is that they are divided into several categories based on their hardware. For instance, larger high-end headsets are usually designed to work with PCs that are enabled to run a VR software. One can also choose to invest in VR headsets that are designed to work with other devices like PlayStation VR and consoles. Nowadays, we can also witness the rise of stand-alone vr goggles that include all the needed hardware onboard. All of these VR headsets are considered pricier, so if this is a problem, you can invest in the cheaper versions. They are made to work with smartphones thanks to the installed slot that is designed to hold the smartphone screen at the right distance. Generally speaking, these VR glasses can work with a large selection of VR apps ranging in price.
Components of Virtual Reality Glasses
- Content Feeds – The content feeds in VR glasses can be supplied only by the hardware of a smartphone, computer or console. This data designs the digital world and it needs to get from somewhere, usually from VR apps and games.
- Controls – The whole exploration and interaction of VR headsets is experienced with the help of a few buttons which are usually located on the headsets. The advanced and more pricey versions of VR’s have a handheld controller, but some of them also offer controllers that mimic real devices like guns and swords. Unlike the others, these VR models interact directly with the hardware that sends the feed.
- Lenses – These headsets also have lenses, the purpose of which is to help the eyes focus on the screen so that it feels as if one is looking into a real environment. The advanced versions of VR glasses allow for lens adjustment, the purpose of which is to reduce eyestrain and realism.
- Displays – The display is the place where the image is displayed to the eyeballs. In the past, two separate displays were included in these goggles (one for each eye). And although this is still a common thing, these days, more and more manufacturers use a single screen or the smartphone as a display.
- Field of View – Generally speaking, the perfect field of view would be 360 degrees, but since this is impossible on headsets, most of them have 100 to 120 degrees. This can significantly improve immersion.
- Tracking Sensors – The advanced models of virtual reality goggles have movement sensors that track when one is moving his/her head, hands or body. That way, they can move the content feed in a similar fashion.
- Audio – The audio in VR glasses is usually supplied as a part of the content feed in the headset itself or as a separate feed that the user needs to wear separately.
- Frame Rate – The rule of thumb is the higher the frame rate, the better the immersion, so the ideal one would be 60 FPS to 120FPS wherein FPS stands for ‘frames per second’. All this should be backed up with powerful hardware. Otherwise, VRs can start slowing down which can result in lost immersion and headaches.
Benefits of Using VR Glasses
- Impressive Visualisation – Without a doubt, the main purpose of these glasses is to allow the user to explore different things and alternate his/her level of experience.
- Great Motivation – VR glasses have made watching things more enjoyable than reading. So, by using these glasses, it has been proven that users are extremely engaged and motivated to learn many new things.
- Improvement of Language Skills – Speaking from an educational point of view, language can be quite a problem for foreign students. With the use of virtual reality, a particular language can be taught with the help of suitable software, which can help such students learn faster and better.
