  3. 3. DESIGN FOR THE WEB <ul><li>Lessons from ELI session on mobility (2010) </li></ul><ul><li>licensing (variable and not transparent) </li></ul><ul><li>learning curve & time sink (Objective C) </li></ul><ul><li>A handful of players (Stanford, New Mexico, Florida) </li></ul><ul><li>The question: Rogue (independent) or “by the books”? </li></ul>
  4. 4. DESIGN FOR THE WEB <ul><li>Some Barriers </li></ul><ul><li>Buy in from admin and some faculty </li></ul><ul><li>Lack of understanding of mobile trends </li></ul><ul><li>Cost </li></ul><ul><li>Licensing </li></ul><ul><li>Coding competency </li></ul><ul><li>Maintenance and sustainability plan </li></ul><ul><li>Finding the right students </li></ul><ul><li>Design challenges (480x320) </li></ul><ul><li>I have other things to do! </li></ul>
  5. 5. DESIGN FOR THE WEB First Steps (1) Licensing (10 months) - key partners (CWS, legal) – don’t go it alone - assurances via policy document(s) - single point of control - pros and cons of enterprise licensing - defining policy, appeasing legal, parallel effort - setting up personal account (iOS SDK, Xcode)

  7. 7. DESIGN FOR THE WEB First Steps (3) Instructional Design - Audience - Instructional objectives - Evaluation and iteration - User interface and nav conventions Features + functions + audience -> Platform
  8. 8. DESIGN FOR THE WEB Platforms
  9. 9. DESIGN FOR THE WEB First Steps (4) Partnerships - Marketing, IT - Other universities - Other departments and units - Source Forge (sharing code) - Infrastructure (central web/IT) - New project proposals / SMEs - Grants
  10. 10. DESIGN FOR THE WEB First Steps (5) Code Stuff - Backing up (Redmine, SVN) - Programmers (audits) - Elegance - cleaning code with time - Acquiring and sharing skills - Database or XML? (SQLite, XML, php)
  11. 11. DESIGN FOR THE WEB First Steps (6) Prototyping - Maps - Paper prototype - Usability and interface - Jakob Nielson (Singh’s study) (mobile redesign) - Omnigraffle (list of others: )

  19. 19. DESIGN FOR THE WEB Sharing Code Source Forge
  20. 20. DESIGN FOR THE WEB <ul><li>Testing </li></ul><ul><li>Paper prototype </li></ul><ul><li>Internal testing (formative) </li></ul><ul><li>- touch, attention, layout, colors, directions - navigational conventions (distance placement) - “faux” augmented reality - GPS is ancillary to tour </li></ul><ul><li>IRB-approved end-user testing </li></ul><ul><li>- more media (videos, audio) & more tours </li></ul>
  21. 21. DESIGN FOR THE WEB Tree Tour Survey Responses <ul><li>Testing </li></ul><ul><li>scrolling </li></ul><ul><li>learning </li></ul><ul><li>liked approach </li></ul>Total Number of Responses Question Agree Disagree Neutral Comments Was the application easy to use? 10 0 0 Was the navigation effective? 10 0 0 Unit distances unhelpful; relative distances and landmark references preferred. Scrolling elements need to be more clearly indicated. Do you think this would appeal to visitors and campus guests? 8 0 2 Maybe if it had more stories, history, medicinal uses, myths, etc... Are you still interested in this application? 8 2 0 I don’t own an iPhone, but would be interested if similar application were developed for my phone. More interested in other different kinds of tours. Did you learn something of value? 9 1 0 Would like to see wider range of content. I already knew much of the information offered. Do you think this approach could be used for other similar topics? 10 0 0

DESIGN FOR THE WEB Tree Tour Survey Responses <ul><li>June of 2011 – Where are We? </li></ul><ul><li>The terrain has changed </li></ul><ul><li>Going native…Titanium, Phone Gap, Adobe CS5.5 </li></ul><ul><li>jQuery, CSS5, HTML5, SQLite </li></ul><ul><li>Objective-C is not easy and is so darn useless in other contexts </li></ul><ul><li>How do Extension professionals develop the skills? Can anyone become a “mobile developer”? </li></ul>
