Outline

• Motivation for End-User Driven Development
• Solution for End-User Driven Development
• DSML for Navigation Applications on S60
• Implementation
• DSML
• Illustration of the use of the language
• Summary
• Future work

3
End-User Driven Development- Motivation

• Open source?
• Enables a possibility to modify application
• Enables developing multiple variants

• Why not?
• Modifying requires to study the existing source
  code
• Don't have time and/or interest
• Variants not satisfying enough?

4
End-User Driven Development- Solution

• Background
• Domain-Specific Modelling Languages (DSMLs)
  provide a possibility for very rapid, iterative
  and incremental software development
• 5-10 times production gains compared to
  traditional software development means witnessed
  in industrial setups.
• Approach
• Domain-Specific Modelling Languages
• Code generators
• Domain-specific frameworks
• and release these as open source and/or open
  models
• Objectives
• Languages that enable rapid development of
  applications/prototypes
• New business opportunities e.g. in mass
  customisation
• Etc.

End-User Driven Development and NavApp

• Currently, not that straightforward to use
• Notation is what it is?
• Solution-space elements should be abstracted -gt
  easier to use
• However, it is a lot easier and faster to develop
  applications vs. manually writing the source code
• Still, my mom probably wouldn't be interested in
  it
• (actually, she wouldn't be in any case)

15
What Next?

• 1.0 version of the framework and language
• Support for multi-person positioning
• Multi-player positioning games
• Social dimension
• Open source?
• Open models??
