  2. What is Woz? • Woz Pro (or Woz for short, Wizard of OzPrototyper) is a new pen-based software environment that enables a user to construct a collection of screen sketches that represent a user-interface, then use them to perform an early evaluation with prospective users. • Woz supports two key activities in the user-centered development process: • Creating a low-fidelity interface prototype that contains a network of screen sketches • Running wizard-of-oz studies in which a human demonstrates the interface to users

  3. Progress • Tool Properties • Transformations • Image Tool • Canvas • Wiki updates • CVS massive merge (Pre Merge BVT, Post Merge BVT)

  4. Tool Properties • Tools independently use toolstrips • Dynamically loaded during runtime • New usercontrol for ‘optionbox’ of tools • Dynamically loaded from tool • Demo

  5. Transformations • Problem: Zooming and panning was slowing down painting because of the large amount of mathematical computations that were being done per point of each entity. • Solution: Transformation matrix that transforms everything within the world coordinate space and an Inverse Transformation matrix that ‘untransforms’ everything back to screen space (pixels) • Problem: Where to keep this transformation matrix? • Solution: Dynamic variables

  6. Image Tool • Image tool is now complete with semi-transparancy and everything • Demo

  7. Canvas • The canvas now uses a transformation matrix which makes things very smooth • No more multi-paneling • Core canvas functionality is now complete

  8. Wiki Update • New Wiki is looking extra sexy • Main page of Wiki is about VEUPL • Woz is a project of VEUPL • Cleaner look, more organized, etc • ChemE is a project of VEUPL • Cleaner look, more organized, etc • Annotated Bibliography

  9. CVS • Well, CVS really helped. • We thought it was gonna be a problem but the merge turned out pretty smoothly • Pre Merge BVT – success • Post Merge BVT – success • Everything is now CVS’d

  10. Next time • Yes, finally, the select tool • Preliminary save/load of Woz prototypes • New thumbnail slider • Revision of architecture • Options boxes and toolstrips for all the tools

  11. Questions?
