Symbian OS
• Symbian OS
– The Symbian operating system is globally the
predominant operating system although performs
poorly in the US
– The Symbian operating system has evolved from the
EPOC operating system that was developed by Psion
as a Personal Digital Assistant (PDA) operating system.
– The Symbian OS grew out of a partnership between
Psion, Nokia, Ericsson, and Motorola, although Nokia
have gradually bought out the other manufacturers.

Windows Mobile & .NET
• Windows Mobile is arguably the leading
player in enterprise and business application
development and deployment.
• The use of the .NET Framework for
development allows for relatively simple
cross-platform development.

Palm
• Palm was one of the early leaders in PDA development
and so has traditionally held a strong position in the
development of enterprise applications, although its
market share has declined significantly over the years
and has long since been displaced by Windows Mobile.
– Indeed, Palm have shipped devices with Windows Mobile,
and this is likely to continue to become a long-term trend
as the brand is still strong within the business community.
– A new version of the PalmOS, WebOS has failed to have a
major impact on the market and unlikely to offer
significant new opportunities for development.

• The iPhone has been heavily hyped but in
terms of market reach is still a niche device.
• However it has enjoyed considerable success
in the US market now accounting for
approximately 25% of Smartphone sales.

Fixing bugs
Nine Inch Nails
• In May 2009, Trent Reznor of the rock band Nine Inch Nails
announced, via his Twitter account, that Apple had rejected an
update to the Nine Inch Nails application due to "objectionable
content".
• The developer posted a message on the Nine Inch Nails discussion
boards explaining the situation further: "v1.0 is live. v1.0.3 got
rejected due to content yet the app has no content in it.
• This was mainly a stability release to fix the bug that crashes the
app for international users.
• The bug was fixed 24 hours after 1.0 went live and we have been
waiting for Apple to approve it ever since.
• Meanwhile the app continues to get a growing number of 1 star
ratings from international users understandably frustrated by the
bug. "But looks like our hands are tied". Apple later permitted the
update.

Mobile Web Strategy
• Why should it be mobile?
– Content should be directly useful to a mobile user
• What content should I make mobile?
– What need does it serve?
– What value does a mobile perspective provide?
• What are the users goals?
– Are these different for mobile users?
Overall Goals
• Business Goals
– What are the business’ goals?
– How does a mobile presence help to achieve these
goals?
– Are there new business opportunities?
• User Goals
–
–
–
–
–
How does the audience benefit from a mobile app?
What tasks will they accomplish?
Does the immediacy of mobile help the user?
What is the context of the information?
How much attention will be paid to the content?
Technical Constraints
•
•
•
•
What type of devices do the users have?
What are the financial constraints?
What is the range of screen sizes?
How much bandwidth will the app have?
Mobile Information Architecture
• Structure information as simply as possible
• Place the right information in the right place
• Consider “click investment”
– Data retrieval relatively slow on mobile
– Lengthy retrievals lead to user frustration
– Every link should clearly label what is being
downloaded so that the user is willing to wait
• Avoid “click disappointment”
Keep it simple
• Limit choices
– Take the content relevant to a mobile user and discard the
rest
– Create a simple, drill-down architecture
• Limit categories
• Limit links to 10 per page
• Code links with access keys (e.g.0-9) so keypad can be used to
access content quickly on olderdevices
• At least one content item, per page!
• Prioritize links by popularity
• Click-streams
– Spread content over multiple pages
Designing for multiple screens
Traditional Web Layout
Possible Mobile Layout
Summary
• Not all about Apple
• (Well 98% of it is!)
• Keep it simple
• But remember…
There’s an app for that…
