Why should we go web-based on
mobile devices?
page 11
Target audience has a great variance of devices
and this will not change
Reason 1
page 12
Vendor Images used without permission, but this slide is their fault
page 13
Native applications are very expensive
Reason 2
page 14
If you need to support for more than one device you need•One developer team for each (sub-) platform
•Use different development frameworks
• Implement different UI guidelines
•Align to the deployment requirements of each platform
page 15
Most applications don’t really need system functions
most of the time
Reason 3
page 16
Serious Smart Phones come with a HTML5
capable web-browser
Reason 4
page 17
Avoid the App-store Mania
Reason 5

How does HTML5 support the development of
mobile applications?
page 19
HTML5 helps to reduce costs
1 application for several devices

HTML5 CSS Features
•Fancier styles and transitions•Web-apps can look as good as native apps
•Consistent visual experience•Lightning fast •First point for improving web-application performance

HTML5 features for Mobiles
•Offline Cache for static content• Users can be offline without loosing the application
•Offline Storage for user data• No data-loss when returning back online
•Geo-location API• Adapt the application to the users location
•Multi-touch Event API• Use Fingers instead of Mice

A few examples

• Offline Cache for static content• Offline Storage for user data• Multi-touch API
page 26
W-Augmented Reality
• Offline Cache for static content• Offline Storage for user data• Geo-location API• Multi-touch API

And if we still need something special
we can still go phonegap or titanium
Binding frameworks that expose native functions to javascript applications.
No loss of development time for re-implementing existing functions
