MICROSOFT HOLOLENS

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.

What is a Hologram?

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 reality.

What is Microsoft Hololens

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.

What is Augmented and Virtual Reality?

Internal Structure of Microsoft Hololens

1.Camera 2.Computer 3.Lenses 4.Vent 5.Sensor 6.Buttons

Inside the Hololens

1.Lenses and Display:- 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.

Then the photons enter the two lenses(one for each eye), where they ricochet between layers of glasses before finally hitting of wearer eye.

How it works? Design Perspective

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 its own.

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 outstreached.

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 command.

Than internal computer works on input command.

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.

Working of microsoft hololens?

Easy to wear and use. Sensitive and responsive to the presence of

pepole. Hololens can be used in army battlefield,where

detailed instruction can be given to the untrained person in the midest of combat.

A useful technology for a A spectacle based computer to reside directly on your eyes rather than your pocket.

Advantage of microsoft hololens

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

glasses.

Dis-advantage of microsoft hololens

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 device.

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.

How is it different from Google glass?

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.
