This document provides an overview of Google's products and services as well as its Android operating system and Google Glass. It discusses that by 1998 Google had indexed 60 million web pages and was successful due to its simple design. It also notes there are over 150 Google services including Google Play, Android, and Google News. Android is an open-source operating system used in smartphones, tablets and other devices. The document outlines Android's architecture, applications, and version history. It also describes augmented reality and Google Glass, a smart glasses prototype, covering its hardware, display, and applications.

4. oBy the end of 1998, Google had an index of about
60 million pages
oThe main reason behind the success of google was because
of its simple design
oIn the year 2003 a companion product to the search engine
Google News was found

5. PRODUCTS AND SERVICES

6. • There are 150+ services offored by Google
• popular products and services:
•
GOOGLE PLAY
•

8. ANDROID
•Linux-based operating system for mobile devices
such as smartphones and tablet computers.
•it also has been used in televisions, gaming
consoles, digital cameras and other electronics.

9. APPLICATIONS
Android has a growing selection of third party
applications, which can be acquired by users
either through an app store such as Google
Play or the Amazon Appstore, or by
downloading and installing the application's
APK file from a third-party site

10. •As of July 2013, there are more than one million applications
available for Android in the Play Store
•As of May 2013, 48 billion apps have been installed from the
Google Play store

11. •Applications that extend the functionality of devices, are
developed primarily in the Java programming language
using the Android software development kit (SDK)
•The SDK includes a comprehensive set of development tools,
including a debugger software libraries, a handset emulator
based on QEMU documentation, sample code, and tutorials

12. Android versions consist of a kernel based on the Linux
kernel's longterm 3.4 branch, varying in version numbers
depending on the actual Android device
Android versions older than 4.0 Ice Cream Sandwich were
based on the Linux kernel versions 2.6.x

15. AUGMENTED REALITY
•Augmented reality (AR) is a live, copy, view
of a physical, real-world environment whose
elements are augmented (or supplemented)
by computer-generated sensory input such
as sound, video, graphics or GPS data.

16. It is related to a more general concept called mediated
reality, in which a view of reality is modified (possibly even
diminished rather than augmented) by a computer.
•As a result, the technology functions by enhancing one’s
current perception of reality. By contrast, virtual reality
replaces the real world with a simulated one

17. •Augmentation is conventionally in real-time and in
semantic context with environmental elements,
such as sports scores on TV during a match
•With the help of advanced AR technology (e.g.
adding computer vision and object recognition)
the information about the surrounding real world
of the user becomes interactive and digitally
manipulable.

19. Google glass?
Google Glass is a wearable computer with an
optical head-mounted display (OHMD) that is being
developed by Google in the Project Glass research
and development project
Google Glass displays information in a smartphone-
like hands-free format, that can communicate with
the Internet via natural language voice commands

20. Glass is being developed by Google X, which has worked on
other futuristic technologies such as driverless cars
•Thad Starner, an augmented reality expert, is a technical
lead/manager on the project.

21. HARDWARE
•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. Sliding backward
shows current events, such as weather, and
sliding forward shows past events, such as
phone calls, photos, circle updates, etc.

22. •Camera
•Google Glass has the ability to take photos and
record 720p HD video. While video is recording, the
screen stays on.
•Can take photos of 5 Megapixels

23. •Display
•The Explorer version of Google Glass uses a Liquid Crystal
on Silicon (LCoS), field-sequential color, LED illuminated
display.
•The display's LED illumination is first P-polarized and then
shines through the in-coupling polarizing beam splitter
(PBS) to the LCoS panel. The panel reflects the light and
alters it to S-polarization at active pixel sites. The in-
coupling PBS then reflects the S-polarized areas of light at
45° through the out-coupling beam splitter to a collimating
reflector at the other end. Finally, the out-coupling beam
splitter reflects the collimated light another 45° and into
the wearer's eye.

24. •Technical specifications:
For the developer Explorer units:
Android 4.0.4 and higher
640×360 Himax HX7309 LCoS display
5-megapixel camera, capable of 720p video recording
