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.

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.

Augmented Reality v/s Virtual RealityAR

• 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.

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.

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.

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.

9

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

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

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

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

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- warmair flows to the sides, where it vents up and out.

14

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.

15

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.

16

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

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.

18

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

generating real like virtual objects.
