multiple devices
They offer users a limited experience
Most mobile websites are simply desktop
content reformatted for mobile devices
They can load pages slowly, due to network
latency
Mobile Application Medium
Type – Mobile Web
Widgets
• Because of the poor experience provided by
the mobile web
• Widget platforms to counter the mobile web’s
weaknesses
• A mobile web widget is a standalone chunk of
HTML-based code that is executed by the end
user in a particular way
• Small web applications that run by themselves
• User can experience designed around short,
task-based operations

•
Pros:
•
•
•
•
Cons:
•
•
•
They are easy to create, using basic HTML,
CSS and JavaScript knowledge
They can be simple to deploy across
multiple handsets
They offer an improved user experience and
a richer design, tapping into device features
and offline use
They typically require a compatible widget
platform to be installed on the device
They cannot run in any mobile web browser
They require learning additional proprietary,
non-web-standard techniques

Application

Mobile web applications are mobile applications that
do not need to be installed or compiled on the target
device
By using XHTML, CSS and JavaScript, they are able
to provide an application-like experience to the end
user
Web applications allow users to interact with content
in real time
After the explosion of Web 2.0, web applications like
Facebook, Flickr, and Google Reader hit desktop
browser
Challenge to bring these application to mobile is the
device fragmentation
A trend that the majority of usage of the mobile web
is coming from the device with better browsers

Content is accessible on any mobile web
browser
The optimal experience might not be
available on all handsets
They can be challenging (but not impossible)
to support across multiple devices
They don’t always support native application
features, like offline mode, location lookup,
filesystem access, camera, and so on
Mobile Application Medium
Type – Native Applications
• The oldest and most common application
medium
• Target the native features of the device
• Can be called “platform application”
• Need to decide which devices is the target
and do testing and certification. Also need
to consider the method to distribute the
application to users

They offer a best-in-class user experience,
offering a rich design and tapping into device
features and offline use
They are relatively simple to develop for a
single platform
You can charge for applications
They cannot be easily ported to other mobile
platforms
Developing, testing, and supporting multiple
device platforms is incredibly costly
They require certification and distribution
from a third party that you have no control
over
They require you to share revenue with the
one or more third parties
Mobile Application Medium
Type – Games
• The most popular of all media available to
mobile devices
• Technically games are just native applications
• Differently from native application:
• They cannot be easily duplicated with
web technologies
• Porting them to multiple mobile
platforms is a bit easier than typical
platform-base applications
• Bulk of the gaming experience is in the
graphics and actually uses very little of the
device APIs

Application Context
• Select appropriate type of application to
present to the user in order for the user to
process and understand the information
presented and complete their goals
• No right or wrong direction
• Only what is best
Utility Context
• The most basic application context
• Simple user experience, short, task-base
scenarios
• Use least amount of user input
• Such as calculator, world clock, weather
forecast, etc
• Use utilities for short, simple tasks, at-aglance information when there is limited
content to display
Locale Context
• Is a newer application type
• More location information is being
published
• At least one thing in common, e.g. a map
• List items in order of distance, with the
nearest item first and the farthest last
• User’s goal is to find information relative to
his present location
• Important to ensure that the user’s present
location is always clearly identified
Informative Applications
• Is an application context in which the one and
only goal is to provide information
• Such as a news site, an online directory, a
marketing site, or mobile commerce site
• The applications’ key task of the user is to read
and understand and no necessary to interact
• Avoid forcing the users to input too much
information with their mobile devices
• Use information applications when users need
information to gain an understanding or
perform a physical task
• Can be used in multimedia contexts such as
desktop and mobile
• Use for information-heavy applications, and for
marketing or promotional applications
Productivity Application
Context
•
•

•
Used for content and services that are heavily taskbased and meant to increase the users’ sense of
efficiency
Users are more committed to accomplishing a
particular goal
Such as message, contacts, or media
Often very structured, presenting information in a
defined hierarchy
Using folder or group to define a sense of order to
the user
It is one of the hardest application context
Information-heavy applications where the user will
need to manage content from a mobile device and
heavily structured, hierarchy-based tasks
Immersive Full-Screen
Applications
• Like a game, a media player
• Common use of the immersive context is
obviously with a game
