Microsoft HoloLens is the future of Holographic Representation. It helps in making smarter decisions and prototype faster when you can inspect every vantage point.

2. IntroductionHoloLens uses the real world as a canvas on which to
overlay virtual elements.
This examines the new technology of Holographic
Projections. It highlights the importance and need of this
technology and how it represents the new wave in the
future of technology and communication.
Microsoft HoloLens, known under development as Project
Baraboo under Alex Kipman(chief inventor), is a pair
of mixed reality head-mounted smartglasses developed
and manufactured by Microsoft.

3. • 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 HoloLens is a smart-glasses headset
that is a cordless, self-contained Windows 10
computer.

4. • 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 supplemented by computer-
generated sensory input in other words the view
of reality is modified by computer such as sound,
video, graphics or GPS data.
• With AR, users are able to interact with virtual
contents in the real world, and are able to
distinguish between the two.

5. Augumented Reality VS
Virtual Reality
 Augumented reality
enhances experiences by
adding virtual components
such as digital images,
graphics, or sensations as a
new layer of interaction with
the real world.
 Augmented reality is being
used more and more in
mobile devices to change
how the real world and
digital images, intersect and
interact.
 Virtual reality creates its own
reality that is completely
computer generated and
driven.
 Virtual Reality is usually
delivered to the user through
a head-mounted, or hand-
held controller. This
equipment connects people
to the virtual reality, and
allows them to control and
navigate their actions in an
environment meant to
simulate the real world.

6. 3D Holographic
Technology
Holography is a technique that allows the light
scattered from an object to be recorded and later
reconstructed. The technique to optically store, retrieve,
and process information. The holograms preserve the
3-D information of a holographed subject, which
helps to project 3D images.

7. Holography is a diffraction-based coherent imaging
technique in which a complex three-dimensional
object can be reproduced from a flat, two-
dimensional screen with a complex transparency
representing amplitude and phase values.
HoloLens use holographic technology to
project large-scale, high-resolution images
onto a variety of different surfaces, at
different focal distances, from a relatively
small-scale projection device.

8. This is mixed
realityMixed reality encompasses a wide range of
experiences that previously were considered to
be only virtual reality. In mixed reality, people,
places, and objects from your physical and
virtual worlds merge together in a blended
environment that becomes your canvas.

9. Feeling present in your environment is a key aspect of
mixed reality, enabling you to move naturally,
interact, and explore in three dimensions.

reality

10. Holograms enhance the
real world• Interacting with holograms in mixed reality
enables you to visualize and work with your
digital content as part of your real world. Realize
mixed reality’s promise with
Microsoft HoloLens.
• Holograms are responsive to you and the world
around you. Microsoft HoloLens enables you to
interact with content and information in the
most natural ways possible.

11. A more natural way to
interactHolograms are responsive to you and the world
around you. Microsoft HoloLens enables you to
interact with content and information in the
most natural ways possible.
• Gaze
• Gesture
• Voice

12. Gaze
Built-in sensors let you use your gaze to move
the cursor so you can select holograms. Turn
your head and the cursor will follow.

13. Gesture
Use simple gestures to open apps, select and size
items, and drag and drop hologram in your
world.

14. Voice
Use voice commands to navigate, select, open,
command, and control your apps. Speak
directly to Cortana, who can help you
complete tasks.

15. Connect, Create &
Explore
Transform the ways you communicate, create,
collaborate, and explore. Your ideas are closer
to becoming real when you can create and
work with holograms in relation to the world
around you.

16. Connect, Create &
ExploreWhen you collaborate, it’s easier to show
than to tell. Your Skype contacts can
overlay sketches and holograms on physical
objects in your view.

17. Parts of HoloLens
It have a major six parts those are bone of it –
• 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
outstreached.
• 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
terabyte of data every seconds.
• Lenses :
Microsoft HoloLens has two display. They are transparent so that wearer can
see the real world behind virtual object. To create project HoloLens image,
light particles bounce around millions of times in the so called light engine
of the device.

18. • 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.
• Sensor :
Sensor track where the wearer is looking and adjust
the display. Motion sensor detect 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. Wearer
also give gesture as input sensor enables the
tracking of user movement.
• Buttons :
On the right side buttons allow user to adjust the
volume and to control the contrast of the hologram.

19. Specifications
• Human Understanding: Spatial sound, Gaze
tracking, Gesture input, Voice support.
• Input / Output / Connectivity: Built-in speakers,
Audio 3.5mm jack, Volume up/down, Brightness up/down,
Power button, Battery status LEDs, Wi-Fi 802.11ac, Micro
USB 2.0, Bluetooth 4.1 LE.
• Power: Battery Life 2-3 hours of active use up to 2
weeks of standby time, fully functional when

21. Create what you imagine
Shape holograms to fine-tune a design, share ideas, and understand
your creations in relation to the real world.
Go beyond what a 2D render can do by working in 3D. Make smarter
decisions and prototype faster when you can inspect every vantage point.
