CSE FINAL YEAR
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
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
Microsoft HoloLens is the first holographic
computer running Windows 10.
It is completely unattached– no wires,
phones, or connection to a PC needed.
Microsoft HoloLens allows user to pin
holograms in his physical environment and
provides a new way to see his world
Microsoft Hololens support augmented
Virtual Reality:- It tricks your eyes into
thinking that you are somewhere else.
Augmented Reality:- It is an extra dimension
over VR since it can show the real world
around wearer with graphic overlayed.
AR can also totally immerse user just like VR
by simply showing pixels everywhere with no
tranparency to the real world.
In virtual world,users are best advised to stay
seated to avoid collisons with physical which
they cannot see in the real world.
1.Lenses and Display:- Microsoft hololens has
two display. they are transparent so that
wearer can see the real world behind virtual
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
2.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 senser
enables the tracking of user movement.
3. computer:- Hololens is not just a visor
connected to a computer, it is a computer on
Hololens contain CPU, battery,GPU and first of
its kind HPU (holographic proceesing unit).
18 sensors flood the brain of the device with
terabyte of data every seconds.
4.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
5.Vent:- the device is more powerfull than a
laptop but won’t overheat- warm air flows to
the sides, where it vents up and out.
6.Buttons:- on the right side buttons allow
user to adjust the volume and to control the
contrast of the hologram.
Microsoft hololens has user interface so it
takes voice,gaze and gestures as input
Than internal computer works on input
Now projection of hologram, for projection
hololens use the HUE(head up display)
method two nanoprojector located at each
side of head and semi transparent visor which
reflect the image as light on users eye.
Easy to wear and use.
Sensitive and responsive to the presence of
Hololens can be used in army
battlefield,where detailed instruction can be
given to the untrained person in the midest
A useful technology for a
A spectacle based computer to reside directly
on your eyes rather than your pocket.
Can be easily damaged or broken.user will
have a tough time taking care of it.
It may lead to accident while driving.
Privacy of people may break due to new
Hololens completely different from google
glass. Google glass was design to perform
the function of smartphone. Like a phone it
support apps,take photos and video so
basically its a expensive version of handheld
Google glass support virtual reality where
user disconnect with real world but in
hololens user,see the real world in front of
them.they can walk around and talk to others
without worrying about bumping into walls.
Visual diagrams would actually show up in
space around the user indicating exactly what
you need to do next.
This application could even extend to the
battlefield, where detailed medical
instructions could be given to untrained
personnel in the midst of combat.
Pin holograms to physical objects so user
can size and scale them in each angle and
with gestuer do all new creation.
