  1. CSE 440: Introduction to HCI User Interface Design, Prototyping, and Evaluation James Fogarty Lecture 05: Design Diamond Eunice Jun David Wang Elisabeth Chin Ravi Karkar Tuesday / Thursday 10:30 to 11:50

  2. Quantity versus Quality One class told they will be graded on quality, another on quantity Bayles and Orland, 2001

  3. Quantity versus Quality The quantity class produces better pots. Why? Bayles and Orland, 2001

  4. Quantity versus Quality The quantity class produces better pots. Why? “While the quantity group was busily churning out piles of work—and learning from their mistakes—the quality group had sat theorizing about perfection, and in the end had little more to show for their efforts than grandiose theories and a pile of dead clay” Bayles and Orland, 2001

  9. Sketching

  10. Sketching A process that enables you to think through ideas and convey design ideas to others very early in the design phase

  11. Quintessential Activity of Design

  12. Design as Choice Elaboration Reduction palette of choices heuristics to choose

  13. Design as Choice Two openings for creativity Palette of choices Heuristics used to choose Why is your design research so important? What you learn directly informs both of these, shaping everything you do this entire quarter

  14. The Design Diamond danger! danger! start generate select danger! intentional! danger!

  15. Properties of Sketches Quick Distinct Gesture Timely Minimal Detail Inexpensive Appropriate Refinement Disposable Suggest and Explore Plentiful Ambiguous Clear Vocabulary

  16. Quick A sketch is quick to make, or at least gives that impression

  17. Timely A sketch can be provided when needed

  18. Inexpensive Cost must not inhibit the ability to explore a concept, especially early in design

  19. Disposable If you cannot afford to throw it away, then it is not a sketch Investment is in the process, not the physical sketch But they are not "worthless"

  20. Plentiful Sketches do not exist in isolation Meaning and relevance is in the context of a collection or series

  21. Clear Vocabulary The way it is rendered makes it distinctive that it is a sketch (e.g., style, form, signals) Could be how a line extends through endpoints Physical sketches have their own vocabulary

  22. Distinct Gesture Fluidity of sketches gives them a sense of openness and freedom Opposite of engineering drawing, which is tight and precise vs.

  23. Minimal Detail Include only what is required to render the intended purpose or concept

  24. Minimal Detail 25

  25. Appropriate Degree of Refinement Make the sketch as refined as the idea If you have a solid idea, make the sketch look more defined If you have a hazy idea, make the sketch look rougher and less defined

  26. Suggest and Explore Rather than Confirm Sketch should act as a catalyst to the desired and appropriate behaviors, conversations, and interactions

  27. Ambiguity Intentionally ambiguous Value comes from being able to be interpreted in different ways, even by the person who created them Sketches have holes

  28. Sketching as Conversation Create Mind Sketch knowledge, representation new knowledge Interpret Requires ambiguity

  29. Sketch vs. Prototype Sketch Prototype Invite Attend Suggest Describe Explore Refine Question Answer Propose Test Provoke Resolve Tentative, non committal Specific Depiction The primary differences are in the intent

  44. The Design Diamond danger! danger! start generate select danger! intentional! danger!

  45. Idea Oscillation danger! danger! start generate select danger! intentional! danger!

  46. Critiquing Sketches is Important Ideas are both good and bad Both are useful in design By making clear what is a bad design, we can avoid actually implementing it Bad ideas help you justify your good ideas Feedback can turn a good idea into a great idea Sketching generates too many ideas to implement

  47. Idea Oscillation

  48. Iteration Toward a Design

  49. Exploration of Alternatives

  50. Exploration of Alternatives … a designer that pitched 3 ideas would probably be fired. I'd say 5 is an entry point for an early formal review (distilled from 100's). … if you are pushing one you will be found out, and also fired. … it is about open mindedness, humility, discovery, and learning. If you aren't authentically dedicated to that approach you are just doing it wrong! Alistair Hamilton VP Design Symbol Technologies

  51. The Converging Path

  66. Some Evidence Greater divergence in designs Prevents sticking with the first idea Allows mashing ideas together Alternatives facilitate feedback Enable comparison Can improve tone of critique

  67. Sketching and the Design Diamond The design diamond is fundamental to understanding what you are doing here Much of your education, including in CSE, has taught you to focus on having the right answer Here it matters what you do long before the end Most ideas get thrown out, including yours Better ideas are great criticism, and frequently would never have come about otherwise
