Mobile Prototyping Workshop

Join the Mobile Prototyping Workshop led by Dean Eckles and Greg Cuellar to explore Flash Lite 2.0 for mobile application development. Learn the key concepts of prototyping and development in mobile environments focusing on deployment challenges, device capabilities, and UI consistency. The workshop covers various platforms and programming options including WAP, J2ME, and Symbian C++. With hands-on examples and insights from experienced instructors, participants will gain practical skills in creating engaging mobile prototypes while understanding the limitations and opportunities of Flash Lite technology.

  1. Flash Lite 2.0 Mobile Prototyping Workshop Dean Eckles Greg Cuellar Mobile Prototyping Workshop

  2. Mobile Prototyping Workshop Flash Lite Development Environment Setup • http://mobpro.pbwiki.com/Install

  3. Mobile Prototyping Workshop About the Instructor Dean Eckles mobile designer and researcher • Designed and built prototypes at Stanford, Yahoo! Prototype Design, and Yahoo! Research Berkeley • M.S. student in Symbolic Systems Program • B.S. Symbolic Systems, B.A. Philosophy • Persuasive Technology Lab • ZoneTag -- a context-aware mobile photo sharing application from Yahoo! Research Berkeley • Changing mobile location disclosure behaviour using persuasive technology

  4. A Survey of Mobile Development Dean Eckles Greg Cuellar Mobile Prototyping Workshop

  5. Mobile Prototyping Workshop Why Mobile Development is Hard • Targeting multiple devices • Intra- and inter-device UI consistency • Varying device capabilities • Completely different platforms • Limited device capabilities • Traditionally great OOP not always the best route • more...

  6. Mobile Prototyping Workshop Some Mobile Development Options • WAP/XHTML • SMS • MMS • Palm • Linux • SVG • more... • Python • J2ME • Symbian C++ • BREW • Flash Lite • Windows Mobile

  7. Mobile Prototyping Workshop Key Platform Considerations • Deployment • Will this prototype be deployed at all? • What devices do our users have? • Development time • Device access • Using e.g. camera, bluetooth, contacts list? • UI • Creating entirely new UI elements?

  8. Python for S60Rapid concept prototyping • Pros • Very rapid prototyping • Clean syntax, OOP potential • Built-in UI widgets • Access to device • Extensible with Symbian C++ • Cons • Slow to prototype new UI • Can be slow at runtime • Very limited deployment • S60 3rd edition security? Mobile Prototyping Workshop

  9. Java Micro Edition (J2ME)"Write once run anywhere" -- sometimes • Pros • Java goodness • Huge deployment • Built-in widgets and powerful drawing capabilities • JSRs add new APIs (e.g. camera) • Cons • Heavy development overhead • Abstract UI or build your own • Finding the "perfect storm" of JSRs Mobile Prototyping Workshop

  10. Symbian C++Very powerful, difficult • Pros • Access to (almost) everything the phone has to offer • Large development, especially in Europe • Cons • Large development and learning overhead • Lots of asynchronous calls • Symbian signing and 3rd edition security Mobile Prototyping Workshop

  11. BREW • Pros • Good install process for users • Owned by Qualcomm, so all issues can be brought up with them • Cons • CDMA phones only (Verizon) • Limited development tools • Severe memory limitations • ? • Complete Qualcomm control Mobile Prototyping Workshop

  12. WAP/XHTML • Pros • Easy to create (just markup) • No install for users • Huge deployment • Make incremental changes • WAP Push • Cons • Very limited UI options • Latency can make each round trip painful • No access to device Mobile Prototyping Workshop

  13. Flash LiteEngaging interactions, with limits • Pros • Very fast prototyping of engaging UI • Browse, install, or mixed model • Make incremental changes • Quickly growing deployment • Cons • Limited deployed outside Japan • Little access to device • Memory limits Mobile Prototyping Workshop

  14. Mobile Prototyping Workshop Prototypingvs.Development

  15. Mobile Prototyping Workshop What Flash Can't Do: Full file system access Camera access Bluetooth Location info Socket connections Flash Lite Abilitieson its own What Flash Can Do: • HTTP/HTTPS connections • Parse XML • Play video and sound • SMS • Some file access Note: Flash can interface with other technologies (such as Symbian C++) to do some things under "Can't"

  16. Mobile Prototyping Workshop Flash Lite Example Applications • Traffic cam • Flickr search

  17. Mobile Prototyping Workshop Quick Flash Introduction • Timeline • “organizes and controls a document's content over time in layers and frames. Like films, Flash documents divide lengths of time into frames.” • Movie clips • “autonomous objects that can respond to events, send messages to other movie clip objects, maintain their state, and manage their child clips.”

  18. Mobile Prototyping Workshop Quick Flash Introduction, cont. • ActionScript • EMCAScript • similar to JavaScript • Important Distinctions • Author-time vs. runtime • Timeline vs. external AS files

  19. Mobile Prototyping Workshop Flash Lite History • Flash Lite 1.0, 1.1 • based on Flash 4 • widely deployed only in Japan (imode) • installed on some S60 phones • Flash Lite 2.0 • based on Flash 7 • just deployed by Verizon, more coming

  20. Mobile Prototyping Workshop Let’s Get Started! • Example 1 – Text fields

  21. Mobile Prototyping Workshop More examples… 2 • Example 2 – Key presses and tweens

  22. Mobile Prototyping Workshop More examples… 3 • Example 3 – Screen switching
