2. Virtual reality (VR) is computer simulated virtual environment that is presented to a user in
such a way that he feels totally immerse in this new and exciting world. In order to achieve
this experience a user have to wear a VR headset that uses a stereoscopic display lenses to
provide 3D image, creating a more in depth view.

3. The history of VR goes way back in late 1960’s. After long years of silence VR starts to see
some movement back in the 1990’s. However, the technology, screen display and computing
power were still requiring improvements. VR concept becomes popular just in the 2012. The
latest development involve a Smartphone clipped into VR headset to achieve the targeted
experience.

Today VR brings a new way of learning and training methodology to improve people skills for
medical-surgery, flight simulator and military exercises. However, the latest applications in
development are within the gaming, movie, sport, history and art industries.
Soon people will take trips to museums, ride racing cars or assist to fashion shows through VR
headsets. Many businesses are investing in the technology.

6. How it works:
PC is connected to a Smartphone. A Smartphone is placed within the headset. A
Smartphone sensor camera communicates back to PC the movements of the player
showing real time images. All the magic hides within the headset lenses which convert
flat 2D images into a 3D virtual world.
How to connect all:
PC – Smartphone: USB cable or Wifi.
Smartphone – VR headset : USB clip
User then needs to download an application “Trinus app” on PC and on Smartphone, the
app streams a game from PC to the phone. A Smartphone needs to be placed inside the
headset (like in the image below).

VR headsets
For serious gaming experience a user can
try out Omni treadmill. This technology will
allow a player to move freely, walk and run
inside the room without worrying hitting the
leaving room furniture
7. VRexperiencerequirements
VR requires few hardware (Quality of PC, Smartphone and headset)
VR quality experience mainly relies on picture quality, resolution and refresh rates
PC
Requires a powerful PC (advised min 8GB)
Graphic card (min 4GB) and Memory card (min 8GB)
Refresh rates: (this is how fast a display can change images) PC has to be powerful
enough to transmit quality frame rate that would make images fluid and not make a player
sick. (minimum is 60fps) Some headsets requires much more, example HTC Vive requires
a 90fps.
VR headset
Tracking motion (also called “6 degrees of freedom”): This hardware captures the head
movements up, down, side by side or angle rotation.
Lenses: As PC and Smartphone provide only flat display, the headset lenses takes flat 2D
images and create stereoscopic 3D virtual environment.
Audio: Sounds need to give an indication where things are positioned even if they are not
in display.
Smartphone
Picture quality depends on phone resolution. Minimum is 720pixel required for decant VR
experience, however to have great and colourful images it is advice to have 1080pixel.
8. Howtoimproveexperience?
Visuals
To improve the visual experience a hardcore gamer will have to invest in PC graphic card .
With better graphic card a PC hardware will be more powerful and will transmit better screen
resolution data. Detailed shadows and colours will be displayed without a drop in
performance. Also powerful PC can provide faster refresh rates.
Audio
Audio is very important to create an alternative reality. Without the right audio matching the
images, the brain will not be cached by the illusion. It is not enough to have traditional
stereo sound as it provides the same sound in both ears. A “3D sound system” or “Binaural”
audio is essential for VR experience. It allows hear sound coming from different orientations
and positions.
Tracking
Tracking and motion simulations has to provide a natural way to interact. A user does not
need to feel much difference between real and imagined world when it comes to turning his
head around, walking and touching objects. Example, gloves need to become more real to
user to feel different degrees of resistance within the motion
9. HowbrandsareusingVR?
Coca-Cola created a VR experience for the 2014 World Cup.
Toyota implemented a driver simulation in VR at the New York International Auto
Show.
Nike created a VR video of soccer player Neymar Jr scoring a goal.
IKEA’s AR catalogue shows what furniture will look like in a room.
Red Bull created a 360-degree VR experience of the Red Bull Air Race.
Nescafe created a VR experience with Google showing users where their coffee
comes from.
Nestle created virtual shopping centres.
Audi created a virtual reality test drive.
More and more companies are investing in VR to provide better experience for their
customers and show all the benefits from their product or service.

10. Conclusion
Virtual Reality has been around for many years, however just recently it becomes a very
popular concept. Today, it provides multiply benefits in many fields starting from military
training, medical surgery, education and of course in gaming.
More and more businesses are starting to see great potential to interact with their
customers. Soon technology will become very popular and more affordable for all of us.
