Developing mobile applications or widgets requires a completely different approach than traditional platforms. Mobile applications should be personal and to-the-point. Glowe provides the technology to build platform-independent mobile widgets in a simple and fast way. This presentation positions Glowe as technology and was meant as introduction to a hands-on lab.

7. Mobile Killer App
 There is no 1 Killer App
 The mobile is a personal device and
mobile applications should reflect that

9. Software : the old way

10. Software : the old way
 Due to the steep learning curve of
traditional software development, the
person with the application idea is
unlikely to be a “coder”.
 This results in a relatively small set of
applications that tend to target large
audiences.
 High complexity leads to high prices in a
low-margin business

11. Mobile Software: the old way
 Not Cross-platform (except J2ME to
some extend).
 Medium to very high entry level.
 Distribution is difficult.

12. Introducing Glowe
Glowe defines a format for describing
applications.
Glowe applications run inside a runtime
environment (or engine) making them
platform independent.
Glowe applications describe the flow of
information.
Glowe applications are made by linking
building blocks.

13. Software: the Glowe way
Mobile applications are about bringing the right
information to the user and allowing
communication in a user-friendly way.
So the Glowe way of developing applications
focuses on :
 Information
 Communication
 Presentation

14. Software: the Glowe way
Technical details:
- Simple, open XML format
- Editable in Notepad (or vi )
- 1 application = 1 file
- A pre-defined set of building blocks
- Multi-platform ready:
- Mobile
- Web
- Embedded
- You’ll score with the ladies

15. Glowe Building Blocks
The Glowe way of application development
offers building blocks to “build” instead of
“code” information centric applications.
There are building blocks available for
- Retrieving information
- Reformatting information
- Combining information streams
- Pushing information back into the cloud
- Displaying information in a rich mobile
interface
- Interacting with the user

16. Current status
 First (actually second) draft of
specification public.
 (XML based) Widget editor with device
emulator.
 Windows Mobile (5+6)
 J2ME client
