  2. Outline • Introduction • SketchWizard Design • SketchWizard Laboratory Evaluation • Related Work • Conclusion and future Work

  3. Introduction Design Prototype Evaluate

  4. Introduction Sketch Prototye/ Pen UI Woz Test http://wireframes-usability.com/2009/11/23/the-beauty-of-web-based-paper-prototyping-part-1/

  5. Introduction • SketchWizard • Create and test Woz • Fast response, simulation • Pen-based UI • Capturing user action • Analysis

  6. Saved Sessions Player SketchWizard Design • SketchWizard Architecture Wizard End User Events Model Copy of Model Updates http://dub.washington.edu:2007/projects/sketchwizard/2007-UIST-SketchWizard-Presentation.zip

  7. SketchWizard Design • SketchWizard Workspaces http://dub.washington.edu:2007/projects/sketchwizard/2007-UIST-SketchWizard-Presentation.zip

  8. SketchWizard Design • DEMO

  9. SketchWizard Laboratory Evaluation • 7 designers • 5 designers have No experience of Woz • All designers have no experience of design a pen-based UI • Two tasks • Wizard • 6th Floor • User • UW CSE Bldg. • 2nd Floor http://dub.washington.edu:2007/projects/sketchwizard/2007-UIST-SketchWizard-Presentation.zip

  10. SketchWizard Laboratory Evaluation Procedure: Introduce Woz, pen-based UI, and SketchWizard • Task 1: • Simulates Windows Journal • Cost 75 min (avg) Results and feedbacks: • Delay Time: 5-15 sec • All designers enjoy the experience of being the wizard • Want to download the tool

  11. SketchWizard Laboratory Evaluation Procedure: 7 days later (after the task1) • Task 2: • Build and simulate was the DENIM web site design tool • Cost 75 min (avg) Results and feedbacks: • Need a message channel between designers and test administrator • Straightforward improvements: • keyboard shortcuts • a rectangle selector • grid snapping

  12. Related Work • Paper Prototyping • Handwriting recognition application • Collaborative digital whiteboard application • Woz Prototyping Tools • NEIMO: • Later-stage prototyping of multimodal interface • SUEDE: • Speech-based UI, early-stage prototyping • CrossWeaver: • Storyboards, early-stage prototyping, analysis tool • Ozlab: • Simulate some continuous interactions • Topiary, DART, and BrickRoad • Woz tool for location-enhanced applications

  13. Related Work • SUEDE (Klemmer 2000) • Topiary(Li 2004) • DART(MacIntyre 2004) • SketchWizard • NEIMO • (Baobo 1993) Design Process More Code Less Code http://dub.washington.edu:2007/projects/sketchwizard/2007-UIST-SketchWizard-Presentation.zip

  14. Conclusion and Future Work • SketchWizard • Enables designers to test early prototypes of pen-based UIs • early-stage Pen UI WOZ works • Fast responses to end-user actions • Future work • Extend SketchWizard with better selection tools and keyboard shourtcuts
