How does virtual reality work?

 

Without a doubt, virtual reality can be a transformative technology one day, although not tomorrow or the following month. Well, at least Mark Zuckerberg described enthusiastically what VR was when buying oculus in 2014.

This technology is interesting, although it still has to provide more on hardware fronts and software to get traction. VR challenges include missing content, overcoming 'nausea' problems, high costs, wiring fears , and the device in front. On the other hand, many entrepreneurs and super technology fans are very happy about VR, expecting it to provide an experience outside the body. 100% converted and certainty that virtual reality is the next big leap, many of them have begun to produce VR content.

So what is VR and how it works? What potential and manufacturer of VR do you have to follow?

What is VR?

Virtual Reality (VR) is a new user interface that is unlike conventional, immersing someone in a digital 3D environment, instead of watching on the screen. The image and content produced by the computer aimed at simulating a real presence through the senses (vision, listening, touch).

Simulation of virtual reality requires two main components: source of content and user device. Software and hardware, in other words. At present, the system includes headsets, al-direction treadmills, special gloves, glasses. VR tools must provide realistic, natural, high-quality images and possible interaction. For this, the device depends on measurements such as:

• image resolution,

• Field of view,

• Refresh rate,

• Motion delay,

• Pixel perseverance,

• Audio / video synchronization.

The main VR challenge is to deceive the human brain to perceive digital content as real. It's not easy, and this "immersion" problem is what still has a virtual reality experience back from the fun. For example, the human visual field does not function as a video frame, and in addition to around 180 degrees of vision, we also have peripheral vision.

However, Vision VR is sure to overcome such problems faster or later, campaigning for concepts and gathering investments in millions. Virtual experiences such as video and 360-degree images, applications and VR games, are already available. There is a pretty good headset option too.

How does virtual reality work?

Usually, the headset displays content before the user's eyes, while the cable (HDMI) transfers the image to the screen from the PC. Alternative options are headsets that work with smartphones, such as Google Cardboard and Gear VR - Phones that act well as VR content and sources.

Some vendors apply the lens to change flat images into three dimensions. Usually, the field of 100/110-degree vision is achieved with VR devices. The next main feature is the frame rate per second, which should be a minimum of 60 FPS as possible to make virtual simulations look quite realistic.

VR / AR / MR: What's the difference?

Knowing what VR a complete picture of the world of technology is not today. Virtual and augmented realities are very similar and often lines between them are very thin. AR adds a real environment with simulated, overlay above. Augmented Reality applies algorithms and sensors to detect the position of the camera, and then exceed the 3D graph/object into the user's display via a smartphone/glasses/projection.

One way to describe the difference between VR and AR is by comparing scuba diving and visiting aquariums. Virtual reality will be like swimming in the sea along with fish, while in augmented reality you will see a fish out of the bag or hand. On the other hand, unlike VR, AR offers more user freedom acting and does not require a display installed in the head.

But actually, Mr (or hybrid reality) is a more sophisticated type of technology, where ar is the subcategory.
