3. What is Hologram?
 A hologram is an object like any other object in the real world,
with only one difference: instead of being made of physical
matter, a hologram is made entirely of light.
 Holographic objects can be viewed from different angles and
distances, just like physical objects.
 Hologram do not offer any physical resistance when touched
or pushed because they don’t have any mass.

4. Technology on which it is based
Hololens uses the technology called Augmented
Reality.
Augmented Reality is a technology that
superimposes a computer generated image on a
user’s view of the real world , thus providing a
composite view.

5. Augmented Reality v/s Virtual Reality
AR
• Augmented reality is a
parallel reality provided by
technology
• In this Reality, digital
objects can be added
seamlessly to the user’s
field of view.
• You can see both physical
objects as well as the digital
objects.
VR
• The entire reality of user is
substituted by a digital
reality.
• In this reality, the user’s
field of view is made up of
digital objects.
• You can see the digital
objects only.

6. Introduction to Hololens5
 Hololens is a pair of augmented reality head-mounted
smartglasses developed and manufactured by Microsoft. Its
one of the first computers running the Windows Holographic
Platform under the Windows 10 operating system.

8. Man Behind Hololens7
 Hololens is the brainchild of Alex
Kipman , a Microsoft employee.
 He was previously working on
Microsoft Kinnect, also known as
grandfather of Hololens.
 It took 7 years for Mr. Kipman
and his team to develop
Hololens.

9. Parts of Hololens
 Camera
 Processors
 Lenses
 Sensors
 Memory
 Speakers
 Vent & Buttons

10. Camera
 The 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.

11. Processor
 In addition to a CPU and GPU , HoloLens features a custom-
made Microsoft Holographic Processing Unit (HPU), a
coprocessor manufactured specifically for the HoloLens by
Microsoft.
 The main purpose of the HPU is processesing and integrating
data from the sensors, as well as handling tasks such as spatial
mapping , gesture recognition, and voice and speech
recognition.
 According to Alex Kipman, the HPU processes "terabytes of
information" from the HoloLens's sensors from real-time data.
10

12. Lenses
 The lenses of the HoloLens use optical waveguides to color
blue, green, and red across three different layers —each with
diffractive features.
 A "light engine" above each combiner lens projects light into
the lens, a wavelength which then hits a diffractive element and
is reflected repeatedly along a layer until it is output to the eye.
11

13. Sensors
 Hololens consists of dozens of sensors that include
accelerometer, gyroscope, magnetometer,etc
 Sensor track where the user is looking and user can input data
by simply gazing at something.
 Motion sensor track user’s movement and adjust the display.
 The sensor can also see users hands, the hands are an input
system: user can interact with whatever he sees by just
touching it virtually.
12

14. Memory and Power
 Apart from its 2 GB RAM, Hololens also has 1 GB HPU RAM. It
also has a flash memory of 64 GB to store datas like hard
drives.
 The HoloLens contains an internal rechargeable battery, with
average life rated at 2–3 hours of active use, or 2 weeks of
standby time. The HoloLens can be operated while charging.
13

15. Speakers, Vents & Buttons
 On the top edge are two pairs of buttons: display brightness
buttons above the left ear, and volume buttons above the right
ear. Adjacent buttons are shaped differently—one concave, one
convex—so that the user can distinguish them by touch.
 The audio is delivered through speakers so that user can listen
to the real world sounds too.
 The device is more powerful than
a laptop but won’t overheat- warm
air flows to the sides, where it vents
up and out.

16. Holo Studio
 Holo Studio is a design system for building 3D objects using
parts and coloring options displayed in a photoshop style
menu.
 The system has some advantages for 3D design, notably the
ability to manipulate and control the orientation of created
objects by changing the position of your head.

17. Advantages of Hololens
 Hololens require no wires, no tethering for its operation.
 It is lightweight and adjustable to fit any adult head size. So,
you can work and play comfortably.
 It doesn’t need any external device like smartphone in the
case of Google glass.
 It has its own processor, memory ,etc making it independent.
 Due to presence of HPU, processing the spatial mapping,
gesture recognition is lot easier.
 It is easy to use and presence of Windows 10 OS makes user
even more comfortable to use.

18. Applications of Hololens
 Remote Instruction – Users can get step by step instructions
on things like home repair from an expert.
 3D CAD – Using the Hololens ro construct and design new
products could be an important commercial use of the device.
 Gamification of Tasks – Hololens has the potential to turn
the boring tasks into fun. For example – Imagine getting on
your treadmill and replacing the world around you with
interesting and interactive scenary as you jog.
 Decorating – It can be used to visualize how new decorations
would look in your house or apartment.
 Learning – It can help students to provide better and detailed
knowledge through holographic objects.
17

19.  Gaming – The possibilities of using the Hololens for gaming
is fascinating. Think of playing angry birds in your living room.
 3D Movies – 3D movies can be upgraded to a whole new
level using Hololens. It could help movie makers bring virtual
elements into the space of user.
 Entertainment – With Hololens you could use a number of
virtual screens of any size, saving you lots of money.
 Heads up GPS - You could see instructions and diagrams laid
out on the road in front of you, giving you unambiguous
instructions about where to go next.
 Medical Applications – Expert surgeons can instruct the local
surgeons to perform critical surgeries. Its application can
extend to battlefield, where detailed medical instructions
could be given to untrained personnel in the midst of combat.

20. Conclusions
 Hololens shows a glimpse of the future world, where the
technology of sci-fi movies will come real.
 It finds a wide range of applications from education,
entertainment to medical and designing.
 It has the potential to replace the display technologies we
presently use.
 It can replace the present generation smart phones and
computers.
 It can also provide a new angle to high-end gaming which
would be like playing in the world of games as shown in Spy
Kids 3D.
 It also requires some enhancements like wider viewing angles,
better battery life, compact designs,etc.
 Enhancement needs to be done in HPU for better graphics for
