microsoft innovation: holo lens

Transfer your world with HOLOLENS


Let me first introduce what it is ??

Microsoft hololens is the first holographic computer running window 10 . Its has no wire ,phones or connection to a PC is needed. It allows you to pin holograms in your physical environment and provides a new way to see your world.
HoloLens is essentially a holographic computer built into a headset that lets you see ,hear and interact within an environment such as a living room or an office space.
Here a new term introduced that is holography - it is a photographic technology that records light scattered from an object , and then presents it in a way that appears in three dimension.Holographic object can be viewed from different angles and distance,just like physical objects, but they donot offer any physical resistance when touched or pushed because they don't have mass.

R u getting confuse with VR technology ??

Hololens technology is different from VR technology .In virtual reality (VR) the user is compelety immersed in a computer -generated world or virtual world.In VR the user are advised to stay seated or keep still to avoid collision with the physical object , they cannot see the real world.
While using hololens you are more connected with the real world around you . we can say it is transforming the ways you create ,connect and explore.

HoloLens has a virtual unlimited set of future application .
example ,
1)Installing a dimmer switch with help from someone in a skype who could see what i was seeing and also markup what i was seeing .Help as to give demonstration.
2) playing augmented reality Mine-craft in a living room.

It seems very helpful to "Explore new place you have never beeen".
scientists at NASA's jet propulsion laboratory will soon be exploring Mars using holograms of mars rover images.They will work as if they can walk on the surface of Mars .As a result they will be able to learn at a faster pace than ever before.

New way to create ,learn what we image .
New way to visualize your work .

COMPUTER GENERATION

Computer is a great invention of science .It was invented by Charles Babbage and also know as father of computers.The term "computer" was first introduced in  1613.Now-a-days we use computer in every field of our life .
Computer is a general purpose device that can be  programmed to carry out a set of arithmetic and logical operations automatically .Modified define of computer is " an electronic device that manipulate information ,or data (store ,retrieve or process data ).The computer or classified on the basic of their generation .there are divided into 5 generation .

First generation(1942-55)
  • They are the fastest calculating devices of their time .
  • Bulky in size because they used thousands of vacuum tubes .
  • generate lot of heat and also consume lot of power .
  • Their hardware failed frequently because of the failure of vacuum tube .
Second generation(1955-64)
  • In this generation transistor replaced the vacuum tube .
  • transistors made them 10 times faster than 1st generation computer .
  • kept  in air -conditional room .
  • larger and faster primary and secondary memories .
  • they used batch operating system
  •  use programming language (FOR TAN,COBOL,ALGOL...)

Third generation(1964-75)
  • smaller in size 
  • kept in air conditioner rooms
  • consume less power
  • more reliable , need less maintenance .
  • larger and faster primary and secondary memories .
  • their production was cheaper and easier .
  • there software were portable and use time-sharing operating  systems.
  • they support on-line computing 
  • Minicomputers were introduced
  • scientific and commercial use  
Forth generation(1975-89)
  • personal computer (PC) were smaller 
  • no need of air-conditional (no ac for PC).
  • less power consuming 
  • much faster and bigger primary and secondary memory 
  • used GUI(graphical user interface)
  • used in offices and home computing 
  • low price ,affordable by individual ownership 
  • they were networked so allowed distributed computing
Fifth generation(1989 - till now)
  • portable PC(notebook and laptops)
  • more faster mainframe computers.
  • consume optimal power 
  • Internet based computing
  • more user friendly 
  • very versatile as they can  be used in every walk of the life .
