How to Choose the Right VR that You Want

Before you buy a VR, you need to know the following things

What is Virtual Reality(VR) and How it changed to life ?

Virtual reality (VR), which can be referred to as immersive multimedia or computer-simulated reality, replicates an environment that simulates a physical presence in places in the real world or an imagined world, allowing the user to interact with that world. Virtual realities artificially create sensory experience, which can include sight, touch, hearing, and smell.

Enter VR — virtual reality

Many people are familiar with the term ‘virtual reality’ but are unsure about the applications of this technology. Gaming is an obvious virtual reality application as are virtual worlds but there are a whole host of uses for virtual reality – some of which are more challenging or unusual than others, such as video, education, Healthcare, etc., There are many more uses of VR than first realized which range from academic research through to engineering, design, business, the arts and entertainment.

The Recent Developments of VR:

The first fifteen years of the 21st century has seen major, rapid advancement in the development of virtual reality. Recently, companies like Google have released interim virtual reality products such as the Google Cardboard, a DIY headset that uses a smartphone to drive it, economical in price; restricted in visual effect.

The restrictions in visual experience of Google Cardboard have led to the enhanced versions which finally answered the unfulfilled promises made by virtual reality in the 1990s will come to market at that time. In an effort to improve the immersive virtual reality experience, improvements has been made on the basis of cardboard with the addition of capture sensor, more complicated built-in control system, focus gear, screen.

As a matter of fact, smartphones alone do not produce the best VR experience, for it requires the support from powerful PC. Only with the addition of high-end CPU or game controller, Professional VR headset ( Deepoon E2 )can achieve the highest resolution and display quality simultaneously aided by optimized comfort and immersion to avoid motion sickness.

How to choose the most suitable VR headset for a starter?

1. Field of view

The field of view is an important factor when choosing your headset.  The human eye has a wide peripheral view, up to 180 degrees , without even moving and up to 270 degrees with eye movement.  This and the amount of detail, depth and clarity are all things that the virtual reality headsets have to take into consideration, in order to fool your brain into believing that what you are seeing is real.  Headsets with a ‘Field of View’ lower than 180 degrees are less likely to fool your brain and the gamer can suffer from a form of a tunnel vision phenomena.  However, a higher field of vision will not necessarily prevent this phenomena unless other conditions are also met, yet it does allow for a field of vision that is greater than a person’s normal peripheral vision, which will reduce the risks of it phenomenally.

What is a good number to look for?

Anything above 90 degrees is generally going to be pretty good

This is what a field of view of about 90 degrees looks like on a Galaxy S6:

00

 

And this is what a 102 degree field of view looks like on my Galaxy S6:

2. Adjustable lenses

IPD and Focus can be adjusted to adapt to your eyes

First, the distance between lenses — the interpupillary distance can often be increased or decreased. If you have wide-set eyes, you’ll want the lenses further apart. If you’re a kid, you’ll want them closer together.

22

The other adjustment is the distance between the lenses themselves and the surface of the smartphone.

On the LeNest above, for example, each lens moves independently when you turn it in its socket. This is particularly useful when you have eyes with a different prescription for each — like I do.

3. Fits over glasses

If you wear glasses, or have friends or family members who do and plan to share the headset with them, you’ll want a headset that’s wide enough to fit over them.

33

4. Weight,Straps & Heat Dissipation

In general, you want a headset that is as light as possible, but not so light that it breaks immediately. For example, a headset made of tissue paper would be extremely light, but not very usable.

Like cardboard, They are good for give-aways, and to give people a taste of what virtual reality feels like, but they’re not a headset that you want to spend much money on

44

 

 

 

Other models, such as VR box, baofeng, Gear box, all have taken f55ull account of user experience by equipping themselves with adjustable headband to release your hands and satisfy various groups. Based on the current functions, they have also minimized the weight to the extreme to alleviate the pressure against your head. Accordingly, heat dissipation accounts for a great deal, since it helps to extend the life expectancy as well as anti-fog performance.

 

 

 

5. Fits over audio and power cables

Sound is important to a really immersive virtual reality experience, especially now that Google Cardboard officially support special sound effects.

Viewers that completely enclose the phone on all sides make it impossible to use headphones — or to plug in a power cable so that you can watch long movies without worrying about power running out.

66

 

6. Controller

Many enclosed headsets don’t have any buttons on them at all, you touch the smartphone screen with having to open up the headset.

Since designers are aware of this problem and typically create apps where in-world interaction is based on looking at some button or object for a few seconds.

Other headset manufacturers bundle remote controllers with their headsets.

77

To be on the safe side, pick a headset that either has a built-in button of some kind, allows direct access to the screen, or comes with a remote.

7. Price & Apps

Right now, prices are all over the place

Viewers made of cardboard run from $1 all the way up to $30

Plastic viewers run from $10 to over $100.

Users may choose according to his or her needs. Right now, there seems to be a sweet spot for virtual reality viewers in the $20 to $60 range. Moreover, you can search for abundant resources from Google Play Store and download to your mobile for later enjoyments.

8. Pixels

This generally refers to the amount of motion blurring that exists. Therefore the fewer the better, I would suggest 3ms or less which translates to 4 pixels of motion blurring per pixels/second.

A high refresh rate. 

The refresh rate is the term for how quickly the images you are seeing are updated.  A higher refresh rate reduces the amount of lag you will experience and should increase the responsive experience you receive making for a more enjoyable gaming experience.  If possible you would like this to at least be in the region of 60 frames per second, such as Deepoon E2.

Low latency 

The time between turning your head and seeing the image change before you is called latency, if the images don’t quite keep up with your line of vision it can feel unpleasant.  Therefore the lower the latency the more realistic your online experience will be

9. Ease of use

It is believed that no one would like to take off the headset and shift into another APP. Most of the open-sided light-weight headsets make this easy — the phone just drops into the tabs.
