Enough Reasons to go mobile? ...but what mobile platform should you target?Let’s look at mobile browsers and engines http://bunkadefresh.com/wp-content/uploads/2010/07/evophones2.jpg

CBC Mobile Site Strategy‣ To cover A, B and C grade mobile browsers by creating three main mobile sites that encompass the different features and limitations of those browsers.
Web App, Native App and Hybrid App‣ Why would you want to have a web app in addition to/ instead of a native app?
Web vs. Native vs. Hybrid Apps Web Apps Native Apps‣ Easy distribution/installation ‣ Possible complicated distribution trough app‣ Native Look & Feel stores, fees/charges‣ Works on all platforms ‣ Strict UI Guidelines‣ Single click using HTML5,Ajax ‣ Easy attention through app store‣ Ofﬂine Storage ‣ Platform-dependent‣ No advertisement restrictions ‣ New app for each platform (knowledge of‣ Fast development time, any web developer language, Objective-C, Java etc) can create web app ‣ Full Access to native APIs, features, i.e.‣ BUT Cannot access all native features, i.e camera, calendar, address book, push compass, camera etc. notiﬁcationExample: Google Gmail Hybrid Apps‣ Web app wrapped around native app‣ Access to native APIs Example: BlackBerry WebWorks, iOS/Android with webviews
What do you have to do to enable your website for mobile?
Mobile Information Architecture"If you design for mobile ﬁrst, you can create agreementﬁrst on what matters most." — Luke Wroblewski, previous Chief Design Architect at Yahoo!
Mobile Information Architecture ‣ Touch phones: big buttons, most of the real-estate should be clickable ‣ Smart phones: track ball, avoid too many links as user has to scroll down, use easy navigation items, i.e. anchors
Mobile Information ArchitectureGuidelines for Mobile URLs:Make it easy for user to type in your mobile site URL ‣ m.cbc.ca ‣ touch.facebook.com ‣ mobile.twitter.comand enable auto redirection ...
Redirect to Mobile ‣ Decide on user agent stringsMozilla/5.0 (webOS/1.0; U; en-US) Mozilla/5.0 (BlackBerry; U; SAMSUNG-D900E/D900EXAIC1AppleWebKit/525.27.1 (KHTML, like BlackBerry 9800; en) AppleWebKit/ NetFront/3.5 Profile/MIDP-2.0Gecko) Version/1.0 Safari/ 534.1+ (KHTML, like Gecko) Configuration/CLDC-1.1525.27.1 Pre/1.0 Version/220.127.116.11 Mobile Safari/ 534.1+ v v v
Redirect to Mobile‣ But don’t limit user to full site access
Customizing for Devices/Platforms‣ Create the best user experience possible based on user’s platform/device‣ Know device/browser speciﬁc features and take advantage of them
Customizing for Devices/OS‣ BlackBerry users get extra information presented <!--#if expr="$HTTP_USER_AGENT = /BlackBerry/" --> <div class="wspromo"> <a href="/m/rich/websignal.html" title=”Subscribe to WebSignal Alert”> Get CBCs Websignal Alert</a> </div> <!--#endif -->‣ iOS: Disable automatic phone number detection <meta name = "format-detection" content ="telephone=no"/>
Make it a Web App‣ iPhone: Full screen without browser bar <meta name="apple-mobile-web-app-capable" content="yes" /> <meta names="apple-mobile-web-app-status-bar-style" content="black-translucent" />‣ iPhone: Add to Home Screen Box‣ iPhone: Home Screen Icon <link rel="apple-touch-icon" href="img/cbc-touch-icon.png"/>
Optimization‣ Reduce the page load / page weight as much as possible
Optimization‣ Use image sprites‣ Image optimization via Smush.it‣ Consider mobile image resizer solutions: Resizing images for all major device widths via device detection‣ Don’t scale images in HTML‣ Use miniﬁed scripts, i.e. js, css (YSlow)‣ Reduce number of DOM Element //avoid var divArr = document.getElementByClassName(“story-images”); //The number of DOM elements is easy to test, just type in Firebugs console: document.getElementsByTagName(*).length‣ Read more under http://developer.yahoo.com/performance/rules.html
