Google Glass is an optical head-mounted display developed by Google X in the shape of glasses. It has a head-up display that replaces the lens of the glasses and allows users to control the device with voice commands or a touchpad. Some key features include the camera, display, software applications from Google and third parties, and potential uses in healthcare as a wearable medical record and in journalism for live reporting.

1. GOOGLE GLASS IS AN OPTICAL HEAD-MOUNTED DISPLAY DESIGNED IN
THE SHAPE OF A PAIR OF EYEGLASSES. IT WAS DEVELOPED
BY X (PREVIOUSLY GOOGLE X)[WITH THE MISSION OF PRODUCING
A UBIQUITOUS COMPUTER.

2. Development
 Google Glass was developed by Google
X, the facility within Google devoted to
technological advancements such
as driverless cars, led by Jacque Aldrich and
his team of 27 prodigies.

3. The Google Glass prototype
resembled standard eyeglasses with
the lens replaced by a head-up
display. In mid-2011, Google
engineered a prototype that weighed
8 pounds (3.6 kg)[citation needed]; by
2013 they were lighter than the
average pair of sunglasses.
In April 2013, the Explorer Edition
was made available to Google
I/O developers in the United States
for $1,500.

5. In early 2013, interested potential Glass users were
invited to use aTwitter message, with hashtag
#IfIHadGlass, to qualify as an early user of the
product.The qualifiers, dubbed "Glass Explorers"
and numbering 8,000 individuals, were notified in
March 2013, and were later invited to pay $1,500
and visit a Google office in Los Angeles, NewYork
or San Francisco, to pick up their unit following
"fitting" and training from Google Glass guides. On
May 13, 2014, Google announced a move to a "more
open beta", via its Google Plus page.

6. Touchpad: A touchpad is located on the side of Google
Glass, allowing users to control the device by swiping
through a timeline-like interface displayed on the
screen.
Camera: Google Glass has the ability to take photos
and record 720p HD video.
Display:The Explorer version of Google Glass uses
a liquid crystal on silicon (Locos)(based on an Locos chip
from Himax), field-sequential color
system, LED illuminated display.
Features

7. Google Glass applications are free applications
built by third-party developers. Glass also uses
many existing Google applications, such
as Google Now, Google Maps, Google+,
and Gmail. Many developers and companies
have built applications for Glass, including
news apps, facial recognition, exercise, photo
manipulation, translation, and sharing to
social networks, such as Face book andTwitter
Software

12. Other than the touchpad, Google Glass can be
controlled using "voice actions".To activate Glass,
wearers tilt their heads 30° upward (which can be
altered for preference) or tap the touchpad, and
say "O.K., Glass." Once Glass is activated, wearers
can say an action, such as "Take a picture",
"Record a video", "Hangout with [person/Google+
circle]", "Google 'What year was Wikipedia
founded?'", "Give me directions to the Eiffel
Tower", and "Send a message to John"(many of
these commands can be seen in a product video
released in February 2013).
Voice activation

14. Several proofs of concept for Google Glass
have been proposed in healthcare.
Drchrono, a MountainView,
California based electronic medical record
company has developed a new application
for the device it claims is the first "wearable
health record." Doctors who register for the
drchrono app for Glass can use it to record a
consultation or surgery with the patient's
permission.
Healthcare applications

15. In 2014,Voice of AmericaTelevision
Correspondent Carolyn Presetting andVOA
Electronics Engineer JoseVega began a web
project called "VOA & Google Glass," which
explored the technology's potential uses in
journalism.This series of news stories
examined the technology's live reporting
applications, including conducting
interviews and covering stories from the
reporter's point of view.
