Presentation transcript:

Sketching and Prototyping Sketches / low / medium / high fidelity prototypes as investment in design increases (red arrow), so does the formality of the criteria whereby concepts are reviewed or accepted From design to evaluation similarly, interface design (idea generation) progresses to usability testing (idea debugging and refinement) From Design for the Wild, Bill Buxton (in press) with permission

Sketching and Prototyping Early design Brainstorm different representations Choose a representation Rough out interface style Sketches & low fidelity paper prototypes Task centered walkthrough and redesign Fine tune interface, screen design Heuristic evaluation and redesign Usability testing and redesign Medium fidelity prototypes Limited field testing Alpha/Beta tests High fidelity prototypes Working systems Late design

Sketches drawing of the outward appearance of the intended system crudity means people concentrate on high level concepts but hard to envision a dialog’s progression Computer Telephone Last Name: First Name: Phone: Place Call Help

Storyboarding a series of key frames as sketches originally from film; used to get the idea of a scene snapshots of the interface at particular points in the interaction users can evaluate quickly the direction the interface is heading Excerpts from Disney’s Robin Hood storyboard, www.animaart.com/Cellar/disneyart/90robin%20storyboard.jpg.html

note how each scene in this storyboard is annotated From www.michaelborkowski.com/storyboards/images/big_bigguy1.gif

Scan the shirt -> Alternate path… Delete that item-> Touch previous item ->
