Microsoft Hololens is the technology that combines the VR with the real world. The company claims that this so-called computer over the head, HoloLens can process TBs of data per second which is insanely huge number. This technology has a lot many application which can not be explained simply as such. Now, the time is not very far when the world will be more like the sci-fi movie.

5. ABSTRACT
This seminar explains the new technology of Holographic Projections
(Microsoft HoloLens). It highlights the importance and need of this
technology and how it represents the new wave in the future of technology
and communication, the different application of the technology the fields
of life it will dramatically affect including business, education,
telecommunication and healthcare.
The paper also discusses the future of holographic technology and how it
will prevail in the coming years highlighting how it will also affect and
reshape many other fields of life, technologies and businesses.
HoloLens is essentially a holographic computer built into a headset that
lets you see, hear and interact with holograms within an environment such
as a living room or an office space. It is based on Augmented reality,
Augmented reality (AR) is a live direct or indirect view of a physical, real-
world environment whose elements are augmented (or supplemented) by
computer-generated sensory input such as sound, video, graphics or GPS
data. The history of augmented reality can be traced back to 1990 and
work undertaken by Professor Tom Caudell as part of a neural systems
project at Boeing. This project was focused on finding new ways to help
the company's engineering process and involved the use of virtual reality.
Augmented reality is the blending of virtual reality and real life, as
developers can create images within applications that blend in with
contents in the real world. With AR, users are able to interact with virtual
contents in the real world and are able to distinguish between the two.

6. INTRODUCTION
Microsoft HoloLens, known under development as Project Baraboo, is a
pair of mixed reality head-mounted smartglasses developed and
manufactured by Microsoft. HoloLens is essentially a holographic
computer built into a headset that lets you see, hear and interact with
holograms within an environment such as a living room or an office
space. It is based on Augmented reality, Augmented reality (AR) is a

7. WHAT IS MICROSOFT HOLOLENS?
HoloLens is essentially a holographic computer built into a headset that
lets you see, hear, and interact with holograms within an environment
such as a living room or an office space. Microsoft has built the headset
without the need to be wirelessly connected to a PC and has used high-
definition lenses and spatial sound technology to create that immersive,
interactive holographic experience. The HoloLens comes with
semitransparent holographic lenses which 'generate multi-dimensional
full-colour holograms'. That means it's not going to be projecting images
into a room that everyone can see. It's cutting-edge stuff, but it's not quite
that advanced yet. Basically, HoloLens is a high-tech computer system
that can be wearable and works according to your gestures with hands,
eyes, etc.
That is an actual picture of wearable augmented reality from Microsoft
named by HoloLens. This is the first holographic computer which is
running on Windows 10. It is completely unattached with no wires,

8. phones or computers needed, it is a computer itself. The premier device
for Windows Holographic, Microsoft HoloLens is a smart-glasses headset
that is a cordless, self-contained Windows 10 computer. It uses various
sensors, a high-definition stereoscopic 3D optical head-mounted display,
and spatial sound to allow for augmented reality applications, with a
natural user interface that the user interacts with through gaze, voice, and
hand gestures.
Codenamed "Project Baraboo," HoloLens had been in development for
five years before its announcement in 2015 but was conceived earlier as
the original pitch made in late 2007 for what would become the Kinect
technology platform. It was introduced with operating systems, such as
Android, iOS and OS X on April 5, 2016. Microsoft has targeted
HoloLens for release "in the Windows 10 timeframe," with the Microsoft
HoloLens Development Edition to begin shipping March 30, 2016,
Microsoft has not set a time frame for consumer availability of HoloLens,
with HoloLens chief inventor Alex Kipman stating that HoloLens will
have a consumer release only when the market is ready for it. Companies
such as Samsung Electronics and Asus had expressed interest in working
with Microsoft to produce their own mixed-reality products based on
HoloLens.

9. PARTS OF HOLOLENS AND ITS SPECIFICATIONS
Microsoft HoloLens have a major six parts those are bone of this product
Camera, Computer, Lenses, Vent, Sensor, Buttons. Let us study them one
by one:
1. Camera :
The project HoloLens depth camera has a field of vision that spans 120
by 120 degree, so it can sense what your hands are doing even when they
are nearly outstretched.
2. Computer :
HoloLens is not just a visor connected to a computer, it is a computer on
its own. HoloLens contain CPU, battery, GPU and first of its kind HPU
(holographic processing unit). 18 sensors flood the brain of the device
with a terabyte of data every second.
3. Lenses :

10. Microsoft HoloLens has two display. They are transparent so that wearer
can see the real world behind the virtual object. To create project
HoloLens image, light particles bounce around millions of times in the so-
called light engine of the device. Then the photons enter the two
lenses(one for each eye), where they ricochet between layers of glasses
before finally hitting of wearer's eye.
4. Vent :
The device is more powerful than a laptop but won’t overheat- warm air
flows to the sides, where it vents up and out.
5. Sensor :
Sensor track where the wearer is looking and adjust the display. Motion
sensor detects wearers movement. The sensor can also see wearers hands,
the hands are an input system: user can interact with whatever he sees by
just touching it. The wearer also gives gesture as input sensor enables the
tracking of user movement.
6. Buttons :
On the right side, buttons allow the user to adjust the volume and to
control the contrast of the hologram.

12. WORKING OF HOLOLENS
Microsoft HoloLens has user interface so it takes voice, gaze and gestures
as an input command. Than internal computer works on input command.
Now projection of hologram, for projection HoloLens use the HUE(head
up display) method two nano projector located on each side of the head
and semi-transparent visor which reflect the image as light on users eye.
Microsoft explains the holographic element in this way: “The key to great
holographic experience holograms that are light point rich, i.e. have a high
holographic density, and are pinned or anchored to the world around you.
To achieve this, HoloLens has been designed for the optimal holographic
density of 2.5K radiants. The more radiant and light points there are, the
brighter and richer the holograms become.” We here divide it into three
parts to make easy to understand, in one of them we study the major
hardware parts of it, and specification than we will move to the real world
example of augmented reality based HoloLens.

13. PROS AND CONS OF HOLOLENS
PROS
 The holographic communication is 100% the future, no mater it is
for VR, AR or on any capable device.
 The quality of this setup is really good. Full body, no gaps, good
colour, low latency.
 Easy to wear and use.
 Sensitive and responsive to the presence of people.
 HoloLens can be used in army battlefield, where detailed
instruction can be given to the untrained person in the midst of
combat.
 A useful technology for a Designing & Futuristic Innovations.
 A spectacle based computer to reside directly on your eyes rather
than your pocket.
 New ways to teach and learn
 Human can explore the places where only robots can reach e.g Red
Planet
CONS
 Can be easily damaged or broken.
 The user will have a tough time taking care of it.
 It may lead to an accident while driving.
 Privacy of people may break due to new glasses.
 This is an expensive setup.
 It also needs complicated positioning and calibrations.

14. CONCLUSION
Holographic computing experiences with Microsoft HoloLens are
different from existing experiences, such as augmented reality (AR) and
virtual reality (VR).
With HoloLens you can connect, create and explore like never before,
create what you imagine, visualize your work, collaborate and explore.
HoloLens with the Holographic processing unit, sensor fusion, power
and grace, advanced optics, build in speakers, spatial sound gives you
the new augmented or the virtual world over the real world. Without
bumping into walls you can watch NetFlix, play Minecraft, use
AutoCAD, talk to Dad on Skype, design a brand new car, and so on.
And what I personally feel is that these technologies will be real life fun
but at the same time, people will gradually stop doing any physical
work. They will simply rely on the technology for everything. However,
HoloLens looks incredibly exciting in terms of the what we have so far,
which is just the glimpse of the future. Talking about the current status,
the team is working with creators and developers all over the world on
exciting new holographic experiences. The era of holographic
computing is here, after all the company also says that “When you
change the way you see the world, you can change the world you see".
