Google Project Glass
What is Google's Project Glass?
Google's Project Glass is Google's attempt to make wearable computing mainstream, and it's effectively a smart pair of glasses with an integrated heads-up display and a battery hidden inside the frame.
Wearable computing is not a new idea, but Google's enormous bank account and can-do attitude means that Project Glass could well be the first product to do significant numbers.
How does Project Glass work?
According to well-informed Google blogger Seth Weintraub, Google's Project Glass glasses will probably use a transparent LCD or AMOLED display to put information in front of your eyeballs. It's location-aware thanks to a camera and GPS, and you can scroll and click on information by tilting your head, something that is apparently quite easy to master. Google Glasses will also use voice input and output.
What are the Google Glass specifications?
he New York Times says that the glasses will run Android, will include a small screen in front of your eye and will have motion sensors, GPS and either 3G or 4G data connections. Weintraub says that the device is designed to be a stand-alone device rather than an Android phone peripheral: while Project Glass can connect to a smartphone via Wi-Fi or Bluetooth 4.0, "it communicates directly with the cloud". There is also a front-facing camera and a flash, although it's not a multi-megapixel monster, and the most recent prototype's screen isn't transparent.
What will I be able to do with Google Glasses?
According to Google's own video, you'll be a super-being with the ability to have tiny people talking to you in the corner of your eye, to find your way around using sat-nav, to know when the subway's closed, to take and share photographs and to learn the ukelele in a day.
OK, what will I really be able to do with Google Glass? Is Google Glass a vision of the future?
Nobody knows. The idea is to deliver augmented reality, with information that's directly relevant to your surroundings appearing in front of you whenever you need it. For example, your glasses might tell you where the nearest decent restaurant is, book your table, invite your friends and show you how to get there, or they might provide work-related information when you're at your desk.
What information we'll use it for, if we use it at all, remains to be seen: like Apple's Siri, it's a technology with enormous potential. It could even end up in contact lenses: one of the Project Glass team, Babak Parviz of the University of Washington, recently built a contact lens with embedded electronics.
Is Google Glass vapourware?
Google's got some of its very best people working on the project, and experts such as wearable computing specialist Michael Liebhold say that "In addition to having a superstar team of scientists who specialize in wearable, they also have the needed data elements, including Google Maps."
Not everyone is convinced. Wired spoke to Blair MacIntyre, director of the Augmented Environments Lab at Georgia Tech, who said "you could not do [augmented reality] with a display like this." MIT Media Lab researcher Pranav Mistry agreed, saying that "the small screen seen in the photos cannot give the experience the video is showing."
There are several engineering issues - making a screen that works in darkness and in bright sunlight is tough - and mobile display technology doesn't offer dynamic focusing, which reads your eye to deliver perfectly clear visuals. Current wearable displays have to be two feet away from your face.
There's clearly a big gap between Google's demo video and the actual product: Google says its photos "show what this technology could look like" and its video demonstrates "what it might enable you to do" [emphasis added by us].
What is the Project Glass price?
The NYT again: according to "several Google employees familiar with the project who asked not to be named," the glasses are expected "to cost around the price of current smartphones." So that's around £500, then, possibly with the help of a hefty Google subsidy.
Is Project Glass evil?
It could be. Google's business is about making money from advertising, and some people worry that Google Glass is its attempt to monetise your eyeballs by blasting you with ads whenever you look at something.
If you think pop-ups are annoying in a web browser, imagine them in front of your face. The ADmented Reality spoof is one of very many parodies that made us laugh.
Some of the parodies actually make a good point by showing people bumping into stuff: heads-up displays can be distracting, and there may be safety issues too. Until Google ships its self-driving car, the thought of drivers being distracted by their glasses is fairly terrifying.
There are privacy implications too. Never mind your web history: Google Glass might record everything you see and do.

Apple Mac OS x and Microsoft windows are two of the world’s
most widely used desktop operating system. apples Mac OS x is more commonly
knows as just simply OS x and is derived from BSD variant OS it is known being customised
and developed by apple computers for their own line of the PCs often referred as Macs
Windows is developed by Microsoft for any PC including apple.
Os x windows both have long line of release in their history. The x in OS
stands for 10 signifying the 10 the major release of the Macs OS within the Mac
OS line up there have been incremented sub versions named after felines
Windows began with 1.0 following the numeric system called
as till,3.1,after that version NT,nt4 and windows 2000for the enterprise and
windows 95 98 etc both lines merged again starting from desktop version windows
xp followed by windows vista,7 and now the latest windows 8 has just been
released
According to one source windows has a market share of 92.8%
compared to Mac OS x is 5.3%
the software used by both these OS are
1. Web browser:- windows uses Internet explorer and apple
uses safari
2. Scripting software used:-windows uses power shell and
apple uses apple script
3. Media players
used:-windows uses media player or media centre and apple uses iTunes or Quick Time
player
Viruses:-
Windows large market share has made it a target for hackers
creating virus and other malicious software. Some counts place the number
windows/ms dos virus at over 50000.it is critical that windows user diligent
run anti virus program and keep them up to date
Infection of Macs running OS x is extremely rare and there
has never been a large scale infections of computers running Mac OS x it is
said that Mac OS doest have even the firewall because the virus in Mac OS is
rare
advantages o f apple
1) Security:-apple computers are much more secured then that
of windows PCs viruses and malware designed for windows based will not run on Mac
OS
2)reliability:-the people who make Mac software’s are the
same persons who make Mac hardware while windows programmers have to take into mealy
infinite variations in hardware these Mac
OS are deigned to only for limited computer which is only designed by apple by
this we can say that the system is much more stable the widows
3) Advanced tech:-The current generation of mack book has pro
features like led monitors ,multi touch mouse track pads etc .Macs desktop features
up to 8 core processor and up to 4 terabyte storage that’s up to 4000gbs
Disadvantages of Mac and advantages of windows Os
1) Macs cannot be upgraded that is customised:-there are upgraded
options when we buy Macs but unlike windows we cannot mix and match the
compo nets.try and upgrade Mac OS ,it’s better to buy and new Mac
Price:-Macs are very expensive . Even the very cheapest
laptop cost you about 1400$ that is about
78000rs in India rupees but windows machine just cost you about 500$
that is 28000rs in India currency
2) playing games requires windows:-there are every few games
available for Macs if you are a gamer the Mac is not a best choice for you, you
can run it in Mac but you have to run windows
Android
Android is a Linux-based operating system for mobile devices
such as smart phones and tablet computers. It is developed by the Open Handset
Alliance, led by Google. Google financially backed the initial developer of the
software, Android Inc., and later purchased it in 2005Google releases the
Android code as open-source, under the Apache License. The Android Open Source
Project (AOSP) is tasked with the maintenance and further development of
Android has a large community of developers writing applications ("apps")
that extend the functionality of the devices. Developers write primarily in a
customized version of Java. Apps can be downloaded from third-party sites or
through online stores such as Google Play (formerly Android Market), the app
store run by Google. In June 2012, there were more than 600,000 apps available
for Android, and the estimated number of applications downloaded from Google
Play was 20 billion.[
Android became the world’s leading Smartphone platform at
the end of 2010.For the first quarter of 2012, Android had a 59% Smartphone
market share worldwide.At the half of 2012, there were 400 million devices
activated and 1 million activations per day. Android has been updated
frequently since the original release of "Astro", with each fixing
bugs and adding new features. Each version is named in alphabetical order, with
1.5 "Cupcake" being the first named after a dessert and every update
since following this naming convention.
List of Android version names:
Cupcake
Donut
Éclair
Froyo
Gingerbread
Honeycomb
Ice Cream Sandwich
Jelly Bean
Applications are usually developed in the Java language
using the Android Software Development Kit, but other development tools are
available, including a Native Development Kit for applications or extensions in
C or C+ Android applications run in a sandbox, an isolated area of the
operating system that does not have access to the rest of the system's
resources, unless access permissions are granted by the user when the
application is installed. Before installing an application, the Play Store
displays all required permissions. A game may need to enable vibration, for
example, but should not need to read messages or access the phonebook. After
reviewing these permissions, the user can decide whether to install the application.The
sandboxing and permissions system weakens the impact of vulnerabilities and
bugs in applications, but developer confusion and limited documentation has
resulted in applications routinely requesting unnecessary permissions, reducing
its effectiveness. The complexity of inter-application communication implies
Android may have opportunities to run unauthorized code.
Several security firms have released antivirus software for
Android devices, in particular, Lookout Mobile Security, AVG Technologies,Avast
F-Secure, Kaspersky
Android smartphones have the ability to report the location
of Wi-Fi access points, encountered as phone users move around, to build
databases containing the physical locations of hundreds of millions of such
access points. These databases form electronic maps to locate smartphones,
allowing them to run apps like Foursquare, Latitude, Places, and to deliver
location-based ads.
Third party monitoring software such as TaintDroid,an
academic research-funded project, can, in some cases, detect when personal
information is being sent from applications to remote servers.
In March 2012 it was revealed that Android Apps can copy
photos without explicit user permission, Google responded they "originally
designed the Android photos file system similar to those of other computing
platforms like Windows and Mac OS. [...] we're taking another look at this and
considering adding a permission for apps to access images. We've always had
policies in place to remove any apps [on Google Play] that improperly access
your data."
