"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.

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

ObjectiveNeed 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

Experimental Result

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 contact2. Save phone number in different manner. 3. Sort the contact list.

Template Based Web Content Adaptation System for Mobile Devices

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.

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 representationProxy-based: a proxy between the server and the does the adaptation.Service-based (distributed): third party provides the adaptation service

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.

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.

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

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

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)

continued..

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.
