Mobile Web App Design …Getting Started Michael Doran, Systems Librarian [email_address]
Okay, we get it! … now what? … iPhone statistics, library services, WorldCat mobile, Android, Millennials, charts and graphs, yada, yada, yada…
buy? build? Hmm. Is it too late to join buy4lib? … now what? www.boopsie.com/ www.blackboard.com/Mobile/
build web app? native app? e.g. iPhone app written in Cocoa requiring download via the App Store “ Most of the folks I know in app development are moving to standardization on web versus device specific development.” Linda Woods AT&T Education Advocate Industry & Mobility Application Solutions 2009 Handheld Librarian Online Conference
This just out… an iPhone OPAC. Download it from the App Store. What? Uhhh. I just bought a Nexus One. Loser!
The Tao of mobile web (app) design
web usability design
design and testing
A mobile web app should do one thing and do it well. A mobile web app should be as simple as possible, but no simpler.
a good mobile web app typical single-interface that-does-everything library web app 1
Simple is as simple does.

“ Moore’s Law doesn’t apply to batteries…as we’re now going into mobile…the cycles count.” Douglas Crockford* Gee, I love what jQuery can do, but maybe server-side processing is the way to go. * Quoted in “Coders at Work” by Peter Seibel, pg. 100

Browser compatibility – don’t skip this Internet Explorer Firefox Chrome
Get right with these before you move on to platform compatibility.
Mobile design – platform compatibility viewport

Test it on the real thing (handset), too! Borrow from colleagues Or, as a last resort… Just need to… test… my app…. one… more time
Don’t forget the documentation!
Mobile/handheld developer sites have useful information on how to “design for small”
Seriously. Read it.
A viewport? Who knew? It’s a small world after all.
Example docs and websites

“ Deliver relevance -- expectations are high and you can only dazzle once.” Cindy Cunningham, OCLC LITA 2009 National Forum Patrons can be persnickety. Maybe I should practice on the Library staff, first.
Hmmm, a staff app… … easier to do a needs assessment … easier to get UI feedback … library has WiFi, so we can use mobile devices without a data plan What would help staff working in the stacks?

If that imbecile up there can do it… How hard could it be? Getting something to beta would only take me a week.
That’s it! Any questions? @dchud: Thanks for giving up your presentation slot.
