University of Washington HCDE 418 Lecture

University of Washington HCDE 418 Sketches - Overview  What is sketching?  Why do sketching?  Sketching properties  What is and is not a sketch?  Sketching vs. prototyping

University of Washington HCDE 418 Sketching Definition  A process that enables you to think through ideas and convey design ideas to others very early in the design phase

University of Washington HCDE 418 Why is sketching useful?  Early ideation  Think through ideas  Force you to visualize how things come together  Communicate ideas to others to inspire new designs  Active brainstorming

University of Washington HCDE 418 Sketch as a dialog with the mind Mind (new knowledge) Create Sketch (representation) Read (seeing that) (seeing as) Buxton, pp. 114

University of Washington HCDE 418 Buxton’s Sketch Properties Quick Timely Inexpensive Disposable Plentiful Clear vocabulary Distinct gesture Minimal detail Appropriate degree of refinement Suggest and explore rather than confirm Ambiguity

University of Washington HCDE 418 Quick  A sketch is quick to make, or at least gives that impression

University of Washington HCDE 418 Timely  A sketch can be provided when needed

University of Washington HCDE 418 Inexpensive  Cost must not inhibit the ability to explore a concept, especially early in design

University of Washington HCDE 418 Disposable  If you can’t afford to throw it away, it’s not a sketch  Investment is in the process, not the physical sketch  However, not “worthless”

University of Washington HCDE 418 Plentiful  They don’t exist in isolation  Meaning & relevance is in the context of a collection or series

University of Washington HCDE 418 Clear vocabulary  The way it’s rendered (e.g., style, form, signals) makes it distinctive that it is a sketch  Could be the way that a line extends through endpoints

University of Washington HCDE 418 Distinct Gesture  Fluidity of sketches gives them a sense of openness and freedom  Opposite of engineering drawing, which is tight and precise Vs.

University of Washington HCDE 418 Minimal Detail  Include only what is required to render the intended purpose or concept

University of Washington HCDE 418 Appropriate Degree of Refinement  Make the sketch be as refined as the idea  If you have a solid idea, make the sketch look more defined  If you have a hazy idea, the sketch will look much rougher and less defined

University of Washington HCDE 418 Suggest and explore rather than confirm  Sketch should act as a catalyst to the desired and appropriate behaviors, conversations, and interactions

University of Washington HCDE 418 Ambiguity  Intentionally ambiguous  Value comes from being able to be interpreted in different ways, even by the person who created them

University of Washington HCDE 418 Forms of Sketching?  Note that the properties Buxton describes doesn’t mention anything about form factor  Can be pencil/pen drawing on paper  Something scraped together in Photoshop  Quick-and-dirty prototyping  Magazine cut-outs  Modifications to existing objects
