4. "Mobile computing: being able to
use a computing device even when
being mobile and therefore
changing location. Portability is one
aspect of mobile computing."
What is Mobile Computing ?
Mobile computing is "taking a
computer and all necessary files and
software out into the field.“
Mobile computing involves mobile
communication, mobile hardware,
and mobile software.
Introduction
The Galaxy Nexus, capable of web
browsing, e-mail access, video
playback, document editing, image
editing, among many other tasks
common on smartphones.

7. Icon-based address
book for android
Device
 Today’s phone address book is
created for a person who can
read/write
 Native language book is not
available
 At least in India
 Even it is available, it still
assumes user to be
literate
 The phone has become
survival tools for bottom of the
pyramid,
 And it supports touch interface
with virtual keyboard
Background

8. Objective
Need a address book which can be used by
illiterate and semi literate as well native language
people alike
 Should not need to have writing skill
 Should not need to know English
 Should be able to scribble instead of
writing

18. Through paper a Icon based contact management android
application has been presented. This application introduces
a new ways to save contact information. This application
mainly for semi literate people.
To improve this application some features must be introduce.
1. Search a contact
2. Save phone number in different manner.
3. Sort the contact list.

Web Content
Adaptation System
for Mobile Devices

21. What is Content Adaptation Used For?
Content Adaptation is a process that based on factors such as the
capabilities of the displaying device or network, or the user's
preferences, adapts the content that has been requested to
provide an optimized user experience.
Content adaptation is usually related to mobile device because it
need special attention to show content of a web page. Mobile
device has some limitation
 limited computational power
 small screen size
 constrained keyboard functionality.

22. ClassificationofAdaptation
Technique From the technology point of view, adaptation techniques are
classified in four groups depending on the location of there
operation.
Server-side: content server does the adaptation (static and/or
dynamic)
Client-side: client device doing transformation or selection of
the best representation
Proxy-based: a proxy between the server and the does the
adaptation.
Service-based (distributed): third party provides the
adaptation service

23. Objective
The purpose of this research project is to design and
implement a content adaptation method for adapting an
web page designed for desktop PC. After adaptation it
delivers the page on a mobile device through mobile
browser.

24. MOTIVATION
 Three A’s: Anywhere, Anytime, Any-device.
 Browsing using a mobile phone is not as easy as browsing using a
common desktop PC.
 Requirements for proper functionality are the main limitations for
using a mobile device to browse through the Internet.
 Screen size and resolution, number of supported colours, entering
text method, computation power, memory size, rate of data
transfer and energy.
• An efficient way is required to display Web Pages on small mobile
screen.
• One of the possible solutions is to adapt web page contents for
mobile handheld devices.

26. Content adaptation phases
• Device Detection
– Detect mobile phone / tablets
– Using user agent http header
• Content Analysis
– parse html using jsoup
– Generate xml
– Call content adaptation phase

27. Content adaptation phases continue…
• Content adaptation
– Parse the xml file using DOM parser
– Parse HTML template and put the contents into
predefine place.
• Template selection

28. DESIGN VIEW
Our content adaptation system has four phases :
•Device Detection
•Desktop/Mobile? If not Desktop: Smatphone/Tablet?
•WURFL/51degrees.mobi
•Content Detection(analyzing and structuring)
•XML generation
•Template Selection
•Smartphone/Tablet
•Responsive Design
•jQuery Mobile
•Content Adaptation
•Text
•Image(color depth degradation)

34. In this adaptation system we consider only text and images in a web page.
In future we may take multimedia contents (audio, video) in our
consideration.
Conclusion and Future Scopes
 In this paper we represent an content adaptation system consist of four phases.
 Our experimental result shows that content adaptation system can increase the browsing
Experience.
 The user interface helps to read the content of the web pages, especially when users are
using handheld devices over the mobile internet.
