The document discusses the importance of designing for visual efficiency in presentations, emphasizing that data should communicate meaning rather than simply present numbers. It highlights the significance of understanding the viewer's needs and constructing visual queries effectively to reduce cognitive effort. Additionally, it provides various strategies to enhance visual clarity and impact, incorporating insights from studies on visual perception.

6. WHAT’S YOUR STORY?

7. - Nancy Duarte Slide:ology Data slides are not really about the data. They are about the meaning of the data.

8. What are you trying to say ?

9. What is your viewer looking for ?

10. Why are you saying it ?

11. What do you want them to do ?

12. Use Cases: Not just for Software ? ! What? Why? Do?

13. You don’t have to use the data just because it’s there *

24. Know your story before starting to design

25. How We See

26. Approximate size of what’s in focus at any given time. Let’s Try Something

27. Represents Approx. 5% of our visual field… … but uses HALF of our visual processing power.

30. Instead, we see through a series of visual queries

33. Attention Discovery WHAT WHERE

35. Answering the WHAT (Understanding What We See)

36. - Features Discovery - Patterns - Objects

37. Neurons are tuned for specific features

49. Patterns are learned over time

50. Aoccdrnig to rscheearch at Cmabrigde uinervtisy, it deosn't mttaer waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteres are at the rghit pclae. The rset can be a tatol mses and you can sitll raed it wouthit a porbelm. Tihs is bcuseae we do not raed ervey lteter by it slef but the wrod as a wlohe.

51. Other Learned Patterns

52. Complex patterns will vary based on the viewer’s experience

53. Over time, higher level patterns are combined

54. Proxies are created

56. Watch carefully…

60. ?

61. What station was it?

62. What colour was the canopy?

63. What kind of trees?

65. We’re capable of rapidly accessing complex patterns…

66. … but to comprehend them we need to process them deeper.

67. Features Pattern Processing Objects

69. Visual Working Memory

70. Designing for Visual Efficiency

71. ... the goal of information design must be to design displays so that visual queries are processed both rapidly and correctly for every important cognitive task the display is intended to support. Colin Ware Visual Thinking for Design

72. Answering the WHERE (Understanding how we search visually)

73. Based on illustration by Colin Ware, Visual Thinking for Design Pattern Testing Eye Movement Move and Scan

74. Visual Efficiency = Reducing Visual Searches

75. Cognitive Effort vs. “ At-a-glance”

85. Luminance Contrast ABCDEFGHIJKLMNOPQRSTUVWXYZ ABCDEFGHIJKLMNOPQRSTUVWXYZ ABCDEFGHIJKLMNOPQRSTUVWXYZ ABCDEFGHIJKLMNOPQRSTUVWXYZ ABCDEFGHIJKLMNOPQRSTUVWXYZ ABCDEFGHIJKLMNOPQRSTUVWXYZ

86. Ensure highest contrast goes to the emphasized elements .

87. Ensure highest contrast goes to the emphasized elements .

88. Use the strongest hues for the most frequently used elements

95. Motion

96. Subtlety is not effective.

97. Avoid visual conjunctions

99. That said… Channels can be layered

101. Be aware of visual interference

103. Avoid Multi-Chunk Queries

106. Visual Search can be primed / tuned

108. Don’t trust YOUR eyes.

109. In Summary

110. Plan Your Narrative

111. Consider Your User’s Visual Queries

112. Design to satisfy those queries as efficiently as possible
