This document discusses designing for mobile user experience. It covers the evolution of mobile devices from keypads to touchscreens, challenges of mobile UI design like smaller screens, and design patterns for touch interfaces. Guidelines are provided for mobile websites and applications, including prioritizing content over navigation, using shallow navigation structures, and ensuring touch targets are appropriately sized. The document concludes with an exercise to design a mobile library application.

10. Evolution – keypads to Touch

11. Mobile UI - A new Paradigm
• Connected devices.
• Touch interfaces
• Acceleration sensing
• Orientation awareness
• Natural animation
• Simulations of physical behavior

12. Touch Targets
• Mobile devices moving to touch UI
• Use appropriately sized targets
• Maintain spacing between targets
• Place important actions in easy to reach
• locations (ergonomics)

14. Native Apps
Advantages:
• Full access to device capabilities
• Integration with other native
applications
• Off-line operation
• ‘Push’ notifications
• Seamless design
• Runs faster
• Dev frameworks
• Installation via app stores
Disadvantages:
• Device specific
• Lock in to device upgrades

15. Web Apps
Advantages: Disadvantages:
• Cross-device support • Less functionality
• Quick development • Limited integration with device
• Instant update Process • Off-line is difficult
• No lock in to app stores (no 30% cut) • Less seamless with other apps
• HTML5 is doing more

16. Hybrid Apps
Advantages: Disadvantages:
• Potentially provides best of both • Early days, which platform
worlds to choose?
• Access to native features • Potentially complex
• Apps are web-based, and therefore
cross platform
• Growing range of third-party
options

17. Mobile approach
Miniaturisation
“... treats the mobile environment and technology as a subset of the desktop
environment.”
It’s a repurpose of existing content
Mobilisation
“... precisely targets mobile user needs, making (the) best possible use of
technology.”
Content and context specific

18. Mobile Web design
Desktop Vs Mobile
• Breadcrumbs
• Deep Explorer views
• Popup Dialogues
• Multiple planes
• Progress indicator
• Error messages and warnings.
• Mobile sites offer better integration with phone
functions - orders by phone or sending promotional
text messages.
• Mobile sites can take advantage of technology that
automatically detects where users are to present local
search results.
