…now what? buy? www. boopsie. com/ www. blackboard. com/Mobile/ build? Hmm. Is it too late to join buy 4 lib?
e. g. i. Phone app written in Cocoa requiring download via the App Store build web app? native app? “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 i. Phone OPAC. Download it from the App Store. What? Uhhh. I just bought a Nexus One. Loser!
The Tao of mobile web (app) design 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. n n standards compliance web usability design minimalist design and testing q q cross-browser cross-platform
a good mobile web app typical single-interface that-does-everything library web app 1
Simple is as simple does.
i. Phone web apps (according to Apple*) * Content on i. Phone: Is It a Webpage or an Application? n Three categories: q q q compatible with Safari on i. Phone optimized for Safari on i. Phone web application W 3 C standards compliant - no framesets or - unsupported technologies (cough, Flash) If it doesn’t look exactly like an i. Phone app it can’t be any good! 2
i. Phone web application tool kits n i. UI: i. Phone User Interface Framework q q n i. Web. Kit: ditto q q n http: //code. google. com/p/iui/ License: BSD http: //iwebkit. net/ License: GNU LGPL Java. Script libraries, CSS code, images… I didn’t have to start from scratch. j. QTouch (j.

“Moore’s Law doesn’t apply to batteries…as we’re now going into mobile…the cycles count. ” Douglas Crockford* Gee, I love what j. Query can do, but maybe server-side processing is the way to go. * Quoted in “Coders at Work” by Peter Seibel, pg. 100
Handheld emulators/simulators Operating System n Generally come with handheld OS SDKs q web. OS (Palm) n q http: //developer. apple. com/iphone/ Android (Google & Open Handset Alliance) n n http: //developer. palm. com/ i. Phone (Apple) n q Software Development Kit http: //developer. android. com/ Web-based simulators (be leery) q Opera Mini Simulator – good n q http: //www. opera. com/mini/demo/ Testi. Phone. com – absolutely worthless
Handheld emulators/simulators Android Palm i. Phone Opera Mini

XHTML/CSS validation n XHTML/HTML CSS Accessibility Get right with these before you move on to platform compatibility.
Mobile design – platform compatibility viewport
Mobile design – platform compatibility Larger buttons for finger tapping
Mobile design – platform compatibility 2
Test it on the real thing (handset), too! Just need to… test… my app…. one… more time Or, as a last resort… Borrow from colleagues
Don’t forget the documentation! n n n Mobile/handheld developer sites have useful information on how to “design for small” Read it Seriously. Read it. A viewport? Who knew? It’s a small world after all.
Example docs and websites n Reading? I just want to code! i. Phone q q q n Principles and Guidelines for Creating Great i. Phone Content i. Phone Human Interface Guidelines for Web Applications Google Groups: i. Phone. Web. Dev Others q q q Opera Mini Developer resources many, more… still more…
“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 Wi. Fi, so we can use mobile devices without a data plan What would help staff working in the stacks?
