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 o Wizard *6 th Floor o User *UW CSE Bldg. *2 nd Floor /projects/sketchwizard/2007- UIST-SketchWizard- Presentation.zip

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

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