This document discusses different types of low-fidelity prototyping techniques including paper prototyping and wizard of oz prototyping. Paper prototyping involves sketching out interface elements on paper and having potential users test tasks to provide feedback. Low-fidelity prototyping allows designers to get early feedback, test designs, and identify issues before significant resources are spent on development.

2. PROTOTYPING

3. PROTOTYPING Fidelity – level of detail Low – many details missing High – similar to finished product Why use low fidelity prototypes? Get feedback faster (cheaper) Experiment with alternative designs Easier to fix problems before time and money has gone into creating the product Keep the design centered on the user Quicker design iterations and releases – get to the solution quicker

5. LOW FIDELITY PROTOTYPING Look Graphic Design Appearance Sketchy Hand drawn Feel Input Method Pointing, writing (different from mouse and keyboard if it is a computer application)

6. PAPER PROTOTYPING Overview Sketch out prototypes of the interface on paper (windows, menus, dialog boxes, etc.) Potential users “walk through” task scenarios using the paper interface Interaction is natural Pointing with a finger = mouse click Writing or talking = typing A member of the team plays “computer” Application Widely practiced in industry Surprisingly effective Helps people work together on a team

7. WHAT YOU CAN LEARN Interface Issues What’s confusing to the user? Where they have problems Subjective feedback on what users like and don’t like Conceptual Model Do users understand how to use and navigate the system? Functionality Does it do what’s needed? Missing features? Nomenclature Are labels and other words confusing the user?

8. WIZARD OF OZ PROTOTYPING Typically used with physical products (I.e., a refrigerator, a space heater, etc.) Is used with computer applications when they are used to simulate future technology (speech recognition, etc)
