Some statisticsMobile Device Usage in US
◦44% of Americans had accessed the Internet using a mobile device by May 2011*
◦For age group 18 – 29, the number is 64%*◦Morgan Stanley analysts predict that the
mobile web usage will be bigger than desktop Internet usage by 2015

more statisticsMobile Device Usage in US Colleges
◦ 51.2% own web-enabled mobile phone (2009)*◦ 62.7% own web-enabled mobile phone (2010) **◦ 33.1% use their web-enabled phone to access Internet
(2009)*◦ 48.8% use their web-enabled phone to access Internet
(2010)**

Building a Mobile Web Three Approaches
One: TranscodingTwo: MiniaturizeThree: Mobilize
6
First Approach: Transcoding
Automatically done by the service carrier
behind the scene.Stripping any video or multimediaShrinking images Breaking large Web pages into a series of
smaller pages that link together.
◦Google transcoder (also called Mobile Optimizer): http://google.com/gwt/n?u=http://yourdomain.com
7
Second Approach – Miniaturize
◦Some Freebies Wirenode (free with ads):
http://www.wirenode.com Wapple (free) : http://wapple.net/
◦CMS Mobile Theme WordPress Mobile Theme Drupul Mobile Edition
8
Third Approach – The Right Approach
MOBILIZEFour Methods
1. Single Design without Auto-Detection2. Single Design with Auto-Detection3. Multiple Designs with Auto-Detection4. Content Adaptation
9
Mobile Web Design Guideline Keep it simple Your mobile web should serve users as maximum as
possible. Only 42% of mobile phones are smartphone. * ◦ That means more than half of mobile phones doesn’t support Javascript
and CSS.◦ Avoid one-page design because it always uses Javascript.
Common characteristics of web-enabled phones◦ Small Screen◦ Difficult to scroll and input◦ Limited resources◦ Mobile users are always on the go
Some design guidelines:◦ Each file size not bigger than 25K◦ Three clicks rule still apply◦ Do not use <table> if possible◦ Standards: Use XHTML - MP 1.1 or 1.2 or XHTML Basic 1.0◦ You can use CSS but don’t rely on CSS

Content SuggestionsHoursContactsClick to Call Ask Us – SMS, IM, Tel, EmailDirection to the libraryMobile Catalog (mobile skin for Voyager is out
there)◦ Recommend: by Denise Dunham from University of
Rochester and Michael Doran from University of Texas at Arlington. Both are available at El Commons)
Mobile E-Collection: mobile pubmed, etc,Third Party Hosting – YouTubeLink to full library website
11
1. Single Design Without Auto-Detection
This is the most easiest to do:◦Some basic HTML knowledge◦Access to your library web server
12
Single Design without Auto-Detection
Step One: Determine Your Content◦ If you have no idea, take a look at other library’s
mobile web. ◦ Usually: Hours, Contacts, Ask Us, FAQ, Directions,
News & Events, Mobile OPAC, Mobile E-Collections
Step Two: Write the Code◦ Use some tools such as Dreamweaver◦ Or use a text editor

Code: index.html

Three More Steps
1. Create a subfolder under document root: for example: /m
2. Publish or ftp the previous file (index.html ) to the subfolder: /m
3. Point the browser to it: http://yourlibrary.org/m
16
2. Single Design with Auto-Detection
What is auto-detection? One url serves either desktop web or mobile web based on the requesting device (PC? Or Mobile Device?) (http://yourlibrary.org)
◦ Write or borrow a program: any of these php, asp, or jsp, etc (easy to do)
◦ Configure the web server (hard to do)
17
2. php Code for Auto-Detection <?php $mobile_browser = '0'; if(preg_match('/(up.browser|up.link|mmp|symbian|
smartphone|android|midp|wap|phone)/i', strtolower($_SERVER['HTTP_USER_AGENT']))){ $mobile_browser++; } if((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml')>0) or ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_SERVER['HTTP_PROFILE'])))){ $mobile_browser++; } $mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4)); $mobile_agents = array( 'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac', 'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno', 'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-', 'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-', 'newt','noki','oper','palm','pana','pant','phil','play','port','prox', 'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar', 'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-', 'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp', 'wapr','webc','winw','winw','xda','xda-'); if(in_array($mobile_ua,$mobile_agents)){ $mobile_browser++; } if (strpos(strtolower($_SERVER['ALL_HTTP']),'OperaMini')>0) { $mobile_browser++; } if (strpos(strtolower($_SERVER['HTTP_USER_AGENT']),'windows')>0) { $mobile_browser=0; } if($mobile_browser>0){ header('Location: http://yourlibrary.org/m/'); } else { header('Location: http://yourlibrary.org/'); } ?>

Three More Steps
1. Save the previous file as index.php
2. Publish or ftp it to document root3. Point your browser to
http://yourlibrary.org/index.php
19
3. Multiple Designs With Auto-Detection
Very complicatedStep one: Develop a set of mobile device
profilesStep two: create multiple designs, each
optimized for a different device profileStep three: Get the device database (WURFL)Step four: Write (or acquire) a program that
can deliver the right version of your site to the right device
For a good example: http://www.lib.ncsu.edu/
20
4. Content Adaptation
Most ComplicatedSingle design that can be adapted to the
needs of different devices on the fly◦Step one: Develop a set of mobile device
profiles◦Step two: Develop a single design◦Step three: Get the device database (WURFL)◦Step four: Write or acquire a program to
serve different device on the fly.
21
Naming Convention
Mobile Site URL: Sub domain? Or Sub Folder
Sub domain is slightly better than sub folder but you need to have the privilege and know how to configure the web server
Example of sub domain:◦http://m.yourlibrary.org/
Example of sub folder:◦http://yourlibrary.org/m/
22
Testing Your Mobile Web
1. You have all the devices (Impossible)2. Emulator: Provided by device vendor.
(cumbersome)3. Firefox Add-on (great tool and easy to use)
W3C Mobile Validator: For rule compliance : http://validator.w3.org/mobile/
23
2 Firefox Add-On(Plug-in)
Great tools to help mobile web development◦Small Screen Rendering
https://addons.mozilla.org/en-US/firefox/addon/526/
◦User Agent Switcher (see next slide for an example) https://addons.mozilla.org/en-US/firefox/addon/5
9/ User Agent Switcher Configuration File: download useragentswitcher.xml_.txt from: http://mobiforge.com/developing/blog/user-agen
