What to mobilize?

• What services are currently available?• What services are applicable on a mobile

device?• What services translate well to the mobile

environment?• What tools can be created easily?• What would be fun to see?

12

Don’t mobilize everything

• Nearly 100 links!• Always can link back to home page, if needed

13

“Mobile” is not just shrinking the page

14

Use only essential, relevant content

When to Make a Native App

• Charging for it• Creating a game• Using specific

locations*• Using cameras• Using

accelerometers• Accessing the

filesystems• Offline users

* Actually available to web-based applications 23

The Case for Mobile Web Apps

“I believe that unless your application meets one of these native application criteria, you should not create a native application, but should instead focus on building a mobile web application.”

— Brian Fling, “Mobile Design and Development”

Our tools

• Mobile website– XHTML 1.0 transitional– CSS– non-essential JavaScript and AJAX

• MIT Mobile Web Open Source Project• Leaned on pre-existing web services• Targeted higher-end devices

Best practices

• Standards and official guidelines– Useful, but slow-moving– Don’t get stuck

• Design Patterns– Still emerging

26

33

Collaborate

• Campus efforts• External projects• Steal what you like• Improve it, so it can be stolen back

34

In Summary…

• Mobile websites are becoming very sophisticated

• Mobile web app development is web development– just a little different

• You can do it
