“Oh my God, Oh my God, Oh my
God! That tiger is about to grasp me and have me for his dinner, God
please save me he is so near.”- With Virtual Reality headset, you
can enjoy a real experience of a jungle safari right on your couch in
the living room. Mark the words ‘real experience’. 3D videos are
in trend from some years now, but Virtual Reality is a little similar
and miles ahead. Let us know more about Virtual Reality headset, a
gadget that is ready to hit the technology market and to take digital
life to next amazing level.
Virtual Reality headset is a
somewhat goggle and helmet combo gadget with the potential to take
the wearer in virtual world that seems real-like because of
computer-simulated environment. Through the computer, Virtual reality
can recreate sensory experiences that include virtual taste, sight,
smell, sound, touch, etc. Some technology big-wigs are working on
creating their own virtual reality headsets for users around the
world.
The concept of Virtual Reality
headsets was started by Oculus but with time well known giants, like-
Google, Microsoft, Sony, Samsung, etc. have stormed into this
industry. Most of these companies have revealed their plans on
respective headsets and the launch in the market for the users is not
very far either.
Moreover, in first of its kind
operation, US department of defense in 2010 used virtual reality
headsets in Future Immersive Training Environment (FITE), a Joint
Capability Technology Demonstration (JCTD), as a three-year
$36-million initiative to demonstrate the value of advanced small
unit in immersible training systems. It demonstrated infantry
applications of Virtual Reality headsets to train soldiers via giving
them feeling of real-life environment of a war projected as in
Afghanistan.
How Virtual environment
works?
Most VE systems are powered by
normal PCs and Graphics that run on high-tech Graphic cards
originally designed for the video gaming community. VE systems use
Head mounted displays (HMD), which are headsets that include two
monitors, one for each eye. The images make up a stereoscopic effect,
giving the illusion of depth. Earlier, HMDs used Cathode Ray Tube
(CRT) monitors, which were large and expensive but provided good
resolution and quality. Later arrived Liquid Crystal Display (LCD)
monitors, which were much cheaper, but, incompetent against the
quality of CRT displays. At present, LCD displays are much more
advanced, with improved resolution and color saturation. All this
makes LCD more common than CRT monitors.
With experiments taking place
to improve the HMDs for better user experience, the Virtual Reality
headsets arrived. They are much lighter and more comfortable to wear
than HMDs. These headsets contain head tracking systems which is
connected to a computer that sends signals to adjust the images seen
by the wearer as they move around in virtual environment. The glasses
allow the wearer to see two separate images which the brain combines
into one to give the illusion of 3D depth.
What is the aim of Virtual
Reality headsets?
The main aim of Virtual
Reality headsets is to gift the wearer a virtual world which is
realistic and behaves in a co-natural way. But any delay in response
time will result in disconnection and, in some cases, user might feel
motion sickness. Initially, the target users of the VR headsets will
be video-gaming community, but it is expected to gradually expand
itself to other sectors, like- Architecture, Movies, Health-care,
etc. Microsoft’s HoloLens, which is still being worked upon,
promises use of VR in communication, engineering, etc. and can really
prove to be a giant leap in Virtual Reality world.
