6. Smartphone Market Share (2010Q2/Gartner)

7. Mobile Operating Systems • Symbian • Android • Windows Mobile/Phone • iOS • Meego • Blackberry • PalmOS

8. Symbian

9. 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.

10. Android

11. Android OS • Linux-based Operating System • Includes: • Hardware reference design • Linux OS kernel • Open source libraries (e.g. SQLite, WebKit, OpenGL, etc) • Runtime which manages and executes applications within a Virtual Machine • Application Framework which exposes underlying functionality • User Interface Framework • Pre-installed applications • Software Development Kit

12. Windows Mobile

13. 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.

14. PalmOS

15. 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.

16. iPhone

17. iPhone 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.

18. MeeGo • Linux-based Operating System • Debian-based • Partnership between Intel and Nokia • Merges Intel’s Mobin with Nokia’s Maemo • Apps developed using Qt • Also supports GTK apps • Netbook variant based on SUSE Linux called Smeegol

22. Age Ratings

23. 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.

39. Device dependence • .mobi breaks concept of device independence • Site optimised for mobile rather than designed for any device • Potentially mitigate by pairing .com and .mobi domains • Automatically redirect mobile devices to .mobi version

40. mobiForge • Developer resource for mobile web development • Technical articles and blogs • Tools • Reference Material • Forums • Directory

41. 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?

42. 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?

43. 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?

44. 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”

45. 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

46. Designing for multiple screens

47. Traditional Web Layout

48. Possible Mobile Layout

49. Summary • Not all about Apple • (Well 98% of it is!) • Keep it simple • But remember…
