All You Need To Know About Virtual Reality
Virtual reality or VR has been a buzzword for many years, but it is now gaining in popularity, as are smartphones and gaming consoles. In the consumer device market, the idea of VR came out of a science fiction movie a few years ago. With the growing popularity of VR technology, people may be curious to know more about this unique technology. The brief information in this article can help you learn a little more about the concept.
The basic idea behind VR technology
Virtual reality technology is used to create a realistic three-dimensional environment or images that can be recognised as real by a human, as if they could actually interact with them. Although we don’t know much about the level of realism of computer-generated cavities, many people use VR headsets and controllers.
Devices such as headsets are used to create a VR environment by mixing software and hardware. This combination of hardware and software in VR makes it different from augmented reality or AR in which a real world overlay is used to add certain objects to create a new world. The perspectives in VR can be more difficult to imagine than in AR. In AR, you can have fixed reference points that can be used by your eyes to navigate and track objects. In VR, on the other hand, realism is difficult to achieve because the entire environment is stimulated.
Some tactile sensations and even smells are used to work on some advanced VR projects. However, in the consumer market, it is limited to hearing, seeing and physically manipulating a few simple objects. But if you know what you can do with these wonderful senses, you’ll be really surprised.
The VR headset
The VR headset is one of the main components used in virtual reality. These VR headsets have been developed by many popular brands, including Sony and Google, with a new approach each time.
Types of VR headsets
These VR headsets can be easily divided into different categories depending on the design of the hardware they can be used with. For use with PCs, larger and higher class headsets are designed so that VR software can be used effectively. But for use with game consoles such as PlayStation, VR headsets in the second category are used. Recently, stand-alone VR headsets have been introduced that include all the hardware options needed to work with them.
The third category of VR headsets includes the cheap quality headsets that are used to work with smartphones. This headset has a slot that allows the smartphone to be placed at a certain distance from the human’s eyes so that he or she can see what is happening on the smartphone screen. These headsets offer a unique experience when used with VR applications. Just as VR headsets vary in design, they also vary in price, from $15 that can be used with Google Cardboard to high-end headsets costing a few hundred dollars.
Virtual reality headset components
To understand the functions of VR headsets, you need to know the components that work together to make these devices work better.
Controls: The headset has a few buttons that allow users to explore and interact with basic elements. You can use manual controls if you are using an advanced version of VR headsets. The controllers used in the more advanced headsets resemble real devices such as swords, guns, etc. The hardware that sends the stream can be used to interact with directly.
Content streams: VR headset hardware provides content streams. This is typical hardware, which is normally used in consoles, phones or computers. It is a data-based hardware that has to come from somewhere to form the digital world. Today, you can experience VR through a video game or an application.
Lenses: Lenses are used in many VR headsets to help focus your eyes on the screen, so that you can easily see the real virtual environment in the headset. In this way, single-screen VR headsets can work effectively. Adjustable lenses are also used in many advanced versions of VR headsets to improve realism and avoid eye strain.
Display: The place where your eyes will see the VR images is called the VR headset display. Previously, VR headset glasses used two separate screens, one for each eye, and remained so for many years. But because of the extra cost of making two screens, it did not gain enough popularity. Today, many simple, low-cost headsets use a smartphone screen as the display.
Frame rate: The impression of the images seen in the VR headset will be better if the frame rate is higher. So preferably choose a headset that offers 60 to 120 FPS and powerful hardware to support it. If you don’t care much about image quality, you don’t have to worry about the frame rate of the headset, but it can cause headaches if the frame rate slows down and the images are no longer captured.
Field of view: normally 360 degrees is the perfect field of view for the open eye, but for a VR headset this is not possible. Most VR headsets have a field of view of 100 to 120 degrees, which helps to enhance immersion.
Audio: Some headsets provide audio from within as part of the content feed or feed it separately using an additional speaker which requires you to wear an additional headset.
Tracking sensors: Users of advanced headsets should be aware that they can move the content stream in the same way they move any part of their body, including their hands and head. These headsets are equipped with motion sensors or use additional hardware to map your movements.
Virtual reality is therefore a unique technology that allows you to see the realism of a virtual world.
