Transcript

  • 1. Beauty is in the eye of the beholder Michele Lanza - University of Lugano
  • 2.
    • Prologue: Ceci n’est pas une pipe
    ArgoUML, 220.000 Java LOC
  • 3.
    • Software Visualization
    the use of the crafts of typography, graphic design, animation, and cinematography with modern human- computer interaction and computer graphics technology to facilitate both the human understanding and effective use of computer software
  • 4. Visual Programming? UML? The description of a thing should not be more complex than the thing itself
  • 5. Static Visualization ArgoUML, System Complexity View
  • 6. Dynamic Visualization CodeCrawler, instance collaboration view
  • 7. Back 2 Reality Is Programming [advanced] text editing?
  • 8.
    • The Adoption Problem
      • Current IDEs do not support visualizations, or they do so only to a very limited extent.
      • Why?
  • 9. Example I - Dr. Scheme visualization of code
  • 10. Example II - Eclipse Creole plugin
  • 11. The Cognitive Overload Problem correlating evolution & bugs of mozilla
  • 12. The Conceptual Gap
      • Software is intangible,
      • having no physical shape or size. [Thomas Ball]
  • 13.
    • Visualizations always sit across a cognitive divide because they are
    • isolated
    • unintuitive
    • overloaded
    • arbitrary
    • ...mostly useless
    The Cognitive Gap
  • 14. Visualization about Software Fractal Figures
  • 15. Visualization of Software The Class Blueprint
  • 16. Useful?
  • 17. Human vs. Machine The two gaps are related the programming language you use influences your thinking Languages come with too much overhead and thus they obscure the actual thing: modeling problems modeling solutions communicating this to the computer
  • 18. Metaphors When you provide visualizations about software the only way to overcome the cognitive gap is to use metaphors This only works if there is a wide adoption [such as design patterns]
  • 19. convoluted languages [like java, C++, etc.] widen the conceptual gap Reflections
  • 20.
    • Epilogue: No Silver Bullet
    Visualization is only a means, not the end
  • 21. Future work close the cognitive gap close the conceptual gap convince people work hard count on the next generation
  • 22.
    • credits:
    • myself, M. D`Ambros, M. Lungu, C. Wysseier
    • [code visualizers]
    • L. Feininger
    • [painter]
    • povray artists
    Style without content is meaningless content without style goes unnoticed
