4.3
Notice the shape of the white space between elements
4.4
What catches your eye first? A three-level visual hierarchy
4.5
Random small areas of white space look unplanned (left). Try to move the space to the outside (right)
4.6
Parts of a grid
4.7
Types of grids: columnar (upper left), modular (upper right), and hierarchical (bottom)
4.8
Comparison of a photo using a central focal point, on the left, with one that uses the rule of thirds, on the right. Viewers typically find the off-center placement more interesting
4.9
A symmetrical design conveys equilibrium. Cutout person courtesy of eLearning Art
4.10
An asymmetrical design is dynamic. Cutout person courtesy of eLearning Art
4.11
Use a stock photo with a linear perspective as a background to add realism to a story or scenario. Cutout people courtesy of eLearning Art
5.1
Photographs are versatile. They can represent something concrete, tell a story, or convey an abstract concept
5.2
Illustrations are compelling because they often have a unique and distinctive style
5.3
You can break apart vector-based clip art and modify it to meet your requirements. Here, the business suit in the upper right is placed on the two characters in military garb. Illustrations from the Microsoft Office® clip art collection
5.4
3-D graphics are rendered from a wireframe model
5.5
Silhouettes are a subtle communication device. They are suggestive rather than literal
5.6
Icons are a minimalist and powerful way to communicate
5.7
Dingbats are a source of icon-like drawings and symbols
5.8
Information graphics are a way to make abstract concepts concrete
5.9
One use of shapes is to structure a screen or slide
5.10
Designing with found art can enhance your message
5.11
A tree seen on the continuum from realistic to more abstract
5.12
Simple visuals like the one on the right are often easier to understand than photographs, as shown on the left, because unnecessary information is filtered out
5.13
This scene was formed from simple geometric shapes in PowerPoint
5.14
Before and after cropping. Notice how the cropped photo on the right is more dramatic and focused than the uncropped photo on the left
5.15
Use a narrow but recognizable slice of several different photos to convey your message in an unusual way
5.16
Break a full-screen image into three separate vertical pieces for an eye-catching effect
5.17
Change the background of conventional photographs to add meaning and a touch of surprise
5.18
Comparison of an image cliché to represent teamwork on the left and a more original approach on the right
5.19
Use one consistent style of illustration, as shown in this job aid teaching HIV/AIDS patients how to care for themselves. Illustrations by Alexey Terekov and Cris Wysong, Kwikpoint
5.20
Use the style number to find clip art with the same look
5.21
Placing varied icons (top) on a similar background (bottom) can improve the consistency of a design
6.1
Typographic terms associated with height
6.2
Characteristics that distinguish serifs
6.3
Inside and outside of letterforms
6.4
Drawing a stress line through the thinnest parts of the letter $o$ helps you see the stroke variation in letterforms
6.5
A collection of serif typefaces, which have small feet at the end of the strokes
6.6
A collection of sans serif typefaces, which are without little feet
6.7
A varied collection of script typefaces
6.8
A collection of decorative typefaces, which include everything from grunge to retro
6.9
Some of the styles you will find in an extended type family
6.10
A superfamily, such as Museo Slab, Museo, and Museo Sans, includes both serif and sans serif typefaces
6.11
Some examples of typefaces that complement each other
6.12
How kerning improves text
6.13
Comparison of placing text on different gradients
6.14
One approach for overlaying text on a photograph
7.1
The three properties used to describe color: hue, saturation, and value
7.2
Warm colors (red, orange, yellow) appear to come to the foreground, and cool colors (violet, blue, green) appear to recede
7.3
The color wheel showing the hues, tints, and shades
7.4
The primary, secondary, tertiary, and complementary colors of the color wheel
7.5
Online tools can generate a palette from a photograph. This one was generated using Adobe Kuler
7.6
An analogous palette uses three adjacent colors
7.7
A complementary palette and a split complementary
7.8
The colors in the triadic palette are equidistant from each other
7.9
A monochromatic palette uses tints and shades of one color
7.10
Notice how the same color appears to vary when placed on a different background
7.11
The same color looks lighter on a dark background and darker on a light background
8.1
Comparison of a graphic with no visual hierarchy (on the left) and one with an established visual hierarchy (on the right)
8.2
Two common eye-scanning patterns are the F- and Z-patterns
8.3
A visual hierarchy at three levels—large title in the center, five smaller entities, and then explanatory text
8.4
Use bright or warm colors to create dominance over other elements
8.5
Isolating an object or person is a way to give an element dominance
8.6
Adding horizontal lines or rules adds emphasis to the text in that space
8.7
A drop capital gives prominence to a block of text
9.1
In a graphic, people perceive the whole before seeing the parts. This is also true for an entire design
9.2
A confusing message from a fragmented design for a job aid (left) versus a strong message from a unified design (right)
9.3
Repetition of shape, user interface elements, and colors are some ways to create a unified design. eLearning screen designs by Kevin Thorn, NuggetHead Studioz, and Trina Rimmer, Rimmer Creative Group
9.4
Similarity refers to repeating visual elements with variation, as in this course design about engineering careers
9.5
To create unity, align elements to the implied lines that are created through the layout process
10.1
The greater the contrast, the easier it is to detect a form
10.2
In this employee web portal design, contrast creates emphasis and attracts the eye, conveying an immediate message that the orientation video is most important
10.3
Contrast is effective for demonstrating comparisons
10.4
Use contrasts in scale to show importance
10.5
Two different patterns express two different emotions
10.6
When it will help convey meaning, use an expressive typeface for screen titles that contrasts with the body text
10.7
Using scale, weight, and color to create typographic contrast
11.1
People see groups before seeing individual elements—under certain conditions
11.2
Proximity shows what is related and what is not
11.3
You can use the grouping principle to convey a message in eLearning scenarios
11.4
Unintended proximity can cause incorrect groupings. Here, it is difficult to tell which label is associated with which group
11.5
Because we perceive similar items as a group, we tend to see vertical or horizontal groups on the left and only horizontal groups on the right, where the shapes are similar in color
11.6
Objects of the same color or shape are perceived as a group
11.7
Using similar styles in user interface design shows which elements are related. Here, the drag objects (bottom) are all similar, as are the targets (top)
11.8
Placing a line between objects creates a condition for perceiving the connected shapes as a group
11.9
Using a ribbon for a connecting line
11.10
The dashed boundary line around the houses suggests they are a group
12.1
Four types of visual cues that guide the eye
12.2
An unintentional visual cue, like this colorful border, could be interpreted as a highlight
12.3
The printer's finger has worked as a visual cue for centuries
12.4
When using directional cues, take advantage of the wide variety of arrow types to make the most effective communication
12.5
Simple geometric shapes, such as triangles and point callouts, are also effective for pointing
12.6
Use a change in color to focus attention on an element that is selected
12.7
The colored highlight is another way to focus attention. Add numbers when the viewing order is important
12.8
A spotlight effect focuses attention
12.9
Eye gaze works as a directional signal to guide the viewer to relevant information
12.10
Radiating lines signal importance
12.11
A stamp effect is another type of visual cue that attracts attention
13.1
Using varied shapes with an expressive typeface is one way to replace bullet points and convey a mood
13.2
Place text on a flat area of color in a photo (left) or on a slightly transparent shape that overlays the graphic (right)
13.3
Use word balloons instead of bullet points. People cutouts courtesy of eLearning Art
13.4
Place text on a panel and replace bullet points with vertical lines
13.5
Ditch the bullets by giving text a more graphical treatment. Here, things to avoid are lightly crossed out and displayed in a distressed typeface
13.6
Wrapping text around a silhouette is an alternative to the bullet list
13.7
Example of a non-hierarchical diagram replacing text bullets
13.8

This book is dedicatedto the hard-working creative learning professionalswho want to make a difference.
Unlike most graphic and visual design books, this one is intended to serve learning professionals. Conventional graphic design books are brimming with insights and examples, but their lessons are focused on designing ads, brochures, logos, and posters. There are excellent principles in these books and I highly recommend starting a design book collection. But the application of commercial graphic design knowledge to learning materials only goes so far. After that, you may feel that you are on your own, flying solo.
The visual design of learning materials has a unique set of requirements compared to that of most other designed products. Although we all share the goal of content clarity, designers of learning experiences are overly concerned that their content be understood, retained, and applied to new situations while also being motivating and engaging.
Furthermore, the materials we design may be quite extensive, such as for a substantial eLearning course, an online learning portal, or a slide set for a full day of training. Our materials might also be interactive, which presents a new set of design issues. Unlike many graphic design studios involved in branding and advertising, we may not have the latitude to innovate as much as we would like. We must ensure that we are true to our highest priority, which is clear communication.
If you are like most learning designers, you have little to no background in visual design. Yet you wear many hats and are often responsible for the visual communication aspect of your materials—whether you create them yourself or collaborate with others. Without the appropriate foundation knowledge, it can be difficult to make the best visual design choices. This book presents a rationale for why you should intensely care about visual design. It presents core principles that will give your work the greatest impact in the least amount of time and provides practical ideas and inspiration for solving visual design challenges.
This book does not teach you how to produce graphics, nor does it promote a particular software package. Many of the suggestions and approaches can be performed with the graphics or slide creation program of your choice. Start with one that is easy to learn and move on to a program with advanced functionality when you need more power. You can make great improvements by applying the foundation principles of visual design, regardless of what program you use.
If I could be anything right at this moment, it would be a good fairy whispering encouraging thoughts in your ear. I'd be hovering over your shoulder every time you embarked on a visual design task. “You'll find a good solution,” I would whisper. “Play with your design and see what you discover.”
I would snuff out that little discouraging voice in your head. You know the one. It's the voice that replays the disparaging comment from an insensitive adult long ago, “Is that a tree or a person?” It's the voice of that relative who proclaimed that no one in the family is creative. It's the story you tell yourself as you compare your talents to those of accomplished artists.
Now is the time to reject those defeating ideas. Why let them follow you through adulthood like an anchor around your neck? When you toss away those negative thoughts, you make room for the pure creativity that pulsed through you as a child. It's still there—somewhere inside.
Don't make the mistake of confusing drawing skills for design skills. The truth is, visual design has little to do with the ability to render. To improve at design, you need to know some basic principles of visual communication. You need to make a commitment to explore and practice so you will develop competence. And you need a heightened sensitivity to seeing design in the world around you—to fine-tune your perceptions.
The fact that you are reading this book is a statement about yourself. You are hoping to gain proficiency in visual design and you have started on the path. Even if you are reading this for a required course, you will appreciate gaining competence in this realm. Who wouldn't? In today's multimedia world, the ability to visually communicate is a necessary and powerful skill.
Think of reading this book as one step in the right direction. This is only a part of your remarkable journey. You will need to continue to learn, practice, and discover. Improving your design skills and abilities is a lifelong endeavor.
May you find enjoyment and success on your path.

Growing into the role of a designer means seeing, thinking, and working like one. This section describes the impact of visual design and how to embrace the role of the designer.
“The need for clear and imaginative communication has never been greater.”
— Phillip B. Meggs
THIS CHAPTERanswers these questions:
Why do visuals benefit learning?
How can I use visuals to improve learning?
What is the impact of visual design on learning?
Learning design and visual design go together like a hand in glove. They are a perfect fit for each other, yet it's rare to hear the terms spoken in the same breath. Even those who acknowledge that graphics are essential for learning may not be aware of the reverberations that visual design has throughout a learning experience. Visual design affects the quality of learning, the value of the communication, and the motivation of the audience members. It leverages the brain's innate capabilities, improves engagement, and satisfies the audience's aesthetic sensibilities.
In this chapter, you'll gain a better understanding of why graphics benefit learning and how design affects the overall user experience.
There's something special about vision. Together the eye and brain work in ways that are no less than wondrous. Consider this. Our eyes are in nearly constant movement, but we rarely notice it. We rapidly recognize objects in complex scenes regardless of their size, color, position, and rotation.
We perceive depth precisely because a different image is registered with each eye. In normal vision, we see six million different colors and lots of detail, both close up and at a distance. We see with different acuity levels depending on the task we are performing (Kosslyn, 1994). We adapt to a wide range of light intensities, so we can see at dusk and also in bright light. And all of this occurs with little to no conscious awareness.
Scientists estimate that over 50 percent of the brain's cortex (the outside layer) is involved in visual processing (Snowden & Thompson, 2012), whereas auditory processing uses around 10 percent and the other senses use even less. Thus, our brains devote more resources to vision than to any other sense.
The pure physiological power of our visual system is a compelling argument for ensuring that you take advantage of the audience's visual intelligence as you design learning experiences.
What happens when you look at a picture? (See Figure 1.1.) The process starts when your eyes pick up sensory data and send signals to a sensory register (also known as sensory or iconic memory). The information lasts here for less than a second and is sent to working memory. Through perceptual processes you select what to pay attention to, based on the features that catch your eye (during pre-attentive processing) and the visual patterns that are meaningful to your goals (during attentive processing).
Figure 1.1How we process visual information.
As you scan the picture, visual chunks are held in working memory for a few seconds. With help from your past experience and knowledge stored in long-term memory, you decode these marks on the screen or page. If the picture is easy to understand, this process happens rapidly. Visual perception is faster than thinking.
Research shows that text accompanied by relevant visuals is better for learning than text alone in many situations and under many conditions (Mayer, 2009). Pictures can strengthen visual discrimination by emphasizing important details. Visuals improve retention and aid in problem solving. Abstract visuals help people comprehend complex information and assist in building mental models. In fact, if you break the learning process down into smaller cognitive actions, you'll see that visuals can be valuable nearly every step of the way.
Pictures are magnets for attention regardless of the medium. People usually look at the graphics of a web page before they read the text (Lin, Yeh, & Wei, 2013). The same is true for newspaper advertisements. Consumer research shows that pictorial ads are better at capturing attention than text ads, and this is true regardless of picture size (Goodrich, 2010; Pieters & Wedel, 2004).
In learning and information dissemination, pictures also draw attention. For example, in a study that explored the best way to convey messages about health risks, pictures attracted and held attention for a longer period of time than the same information produced in text alone (Smerecnik, Mesters, Kessels, Ruiter, De Vries, & De Vries, 2010).
Pictures of people and particularly pictures of faces summon our visual attention. Also, certain attributes capture attention without conscious awareness. Vivid colors, striking shapes, and motion capture pre-attentive attention.
Encoding information in long-term memory is an essential activity of learning, and this is one more place where visuals shine. Relevant pictures help people remember corresponding text. By relevant, psychologists mean pictures that represent the objects or concepts presented in the text (Levie, 1987).
This may be due to the fact that our memory is typically better for concrete things than for abstractions. Pictures provide a concreteness—an association with a sensory experience—that has advantages over words, which are more symbolic.
Pictures help learners understand complex text or narration because they convey information about spatial structure. We rely on the spatial structure of visuals to provide meaning. In a diagram or chart, designers use techniques that show relationships, such as placing related elements together in a group. This quickly communicates what is associated in a way that may be more difficult through text alone. The structural organization of a picture is thought to have a scaffolding effect that helps in the construction of new mental models (Eitel, 2013).
Because graphics hold attention for a longer period of time than text, researchers believe the additional attention plus the ease with which graphical information is extracted is another benefit to comprehension (Smerecnik, Mesters, Kessels, Ruiter, De Vries, & De Vries, 2010). Also, pictures can be rendered with extreme specificity. They can emphasize or exaggerate details to reduce ambiguity. This precision improves understanding.
Certain types of graphics, such as information graphics, facilitate making inferences and solving problems. They function as an external memory aid by using arrangements that organize information in meaningful ways (Larkin & Simon, 1987). It is easier to make use of massive data when it is expressed as a graph. It is easier to work with a complex network of ideas when they are illustrated in a diagram.
In terms of learning procedures, the combination of pictures and text is ideal. One study showed that line drawings and text were as effective as video when the drawings used arrows to show the actions involved in performing a simple medical procedure (Michas & Berry, 2000).
Looking at the range of cognitive tasks that adults perform, it becomes obvious that graphics support and facilitate thinking, problem solving, and learning. Regardless of whether the graphic is a simple icon, an elaborate illustration, or a complex data visualization, visuals provide a rich and textured language for expressing ideas.
The value of visual design becomes clear when you consider the picture superiority effect. Several decades of research have established that in most recall and recognition memory tasks, concepts that are learned by viewing pictures are remembered better than their counterparts in words (Hockley & Bancroft, 2011). This phenomenon is known as the picture superiority effect.
Dual coding. Why do visuals add an element of memorability to information? One theory, known as dual coding, states that people process information through two distinct systems, one for verbal information (written and spoken words) and one for nonverbal information (images). According to this theory, pictures have an advantage over words by being encoded into long-term memory through both the visual and verbal channels. That is, pictures are encoded as an image as well as spontaneously given a verbal label. In contrast, words are encoded with just one verbal code (Paivio, 2006). Two codes written to memory increases the chance of retrieving the information compared to information that is coded in only one way (Paivio, 1986).
This theory would also explain why the picture superiority effect improves with chronological age. If a person does not have the inner language available to formulate a name for a picture, then dual coding does not seem to occur (Whitehouse et al., 2006).
