Gestalt Principles
1. Rules for the system of the home screen.
The newspaper title is on the very top and covers the whole width, followed by a category bar. The rest of the image is basically divided into 2 columns. The right column will be divided into 2 or 3 or 4 according to the articles.
2. Gestalt principles:
a. Contrast: There is contrast between title and content. Title is big and content is small. When the mouse passes something with a link, the words will turn blue, which is different from normal black color.
b. Emphasis: The titles are emphasized naturally because of the contrasts.
c. Balance: The page is balanced as there are lines to make sure the articles in one sector are both laterally and longitudinally aligned. There is also enough white space. The right column seems to be a white space when you scroll down, which give the page a balance.
d. Harmony: About 30%-50% of the website is images, which attains a harmony of images and words.
e. Rhythm/Movement: Some articles are lower than the articles next to it, which attracts people to scroll down.
3. The overall composition work in harmony. The colors are clean and comfortable. Although there are lots of articles, it doesn’t looks messy as they are separated by lines. Also, the contrast between title and content help me to get the information. It’s both balanced and with certain level of hierarchy.
4. Designs are popular today are with big photos/pictures. It seems that people are more willing to “read” images rather than words today. Not only the title picture, but also pictures for other articles are used to convey the information. In another word, the use of image is generally increased. Also, column design is still popular among digital newspaper design, like it’s in paper ones. The difference is that the number of columns has been decreased to 2-3.

2. System of hierarchy:
a. color: All the words are black except the highlighted ones with color red or blue. The images keep the original colors.
b. typography: The titles of article are “inherit”, the contents of the article are “Georgia”.
c. image: Almost all the images are the ideal rectangles. They are either placed on the top of the article above the title, or on the left part of the article under the title.
d. composition: The whole page, expect of the newspaper title, is basically divide into 2 columns. The right column will be divided into 2 or 3 or 4 according to the articles.
3. My decisions on reading were subjective. As I am more easily to be attracted by images, I will prefer to read the articles with images.

Gestalt Principles and Affordances on WSJ.com

Gestalt in the News

Analysis of rules seen in the front-page of www.wsj.com (The Wall Street Journal)

Rule #1 – Headings
Consistent formatting helps show what kind of text something is – tab, article title, body, or subsection header. The tabs are indicated by sans serif font (Whitney SSM or Arial), a slightly heavier weight font, small size, black. The titles of articles are indicated by serif font (Chronic Display or Georgia), bold, larger size, black. The body text of articles is serif font (Chronicle SSM or Georgia), regular font weight, small size, black. The subsection/topic headers are sans serif font (Whitney SSM or Helvetica), small caps, of various colors, but all colors have similar value.

Rule #2 – Borders
Borders divide up the page, and the border thickness and color denote how “deep” this divide is. Between completely different sections such as between the tabs and the content, there is a strong black thick border. Between different articles in the same section, there is a pale thin gray border.

Rule #3 – “Read More” Arrow
There is a “right arrow” for each section to read more. This rule is somewhat inconsistently applied. For the “Opinion” section this arrow is at the top to the right of the section title, and is close enough to the section title to be associated with the section title. The “Markets” section has its arrow at the bottom with an additional smaller “MARKETS” label. The “What’s News” has it at the top, but this header bar is so wide that the arrow all the way to the right is so far away from the “What’s News” at the left that in my mind they are not clearly associated.

Rule #4 – Data Visualizations
Data visualizations use a consistent shade of blue for the graphs. The text is gray sans serif.

Rule #5 – 12 Column Grid
The page appears to be laid out on a 12 column grid. In its widest layout, the four columns on the page are, from left to right, width 3, width 4, width 2, width 3.

Rule #6 – Image Aspect Ratio
The image aspect ratio is usually the same for images. This helps gives rhythm rather than chaos to the webpage, which is crowded with text and images.

*Gestalt Principles in play*

Contrast:
The WSJ website uses a reverse-contrast to distinguish between static content on the site (black foreground on white background) and the dynamic content represented by the stock ticker at the top (white foreground on black background). This according to us is a very good use of contrast as it in terms of scale (thin strip compared to the rest of the site), it creates a different context of lower relative emphasis.

Emphasis:

There are a few different ways the WSJ hompage communicates emphasis. The first one is through space. Note that the headings for each subsection of the paper are not much bigger than the rest of the text on the page. The way they stand out is that their entire right side is cleared, giving that word notable prominence, as nothing is on its same level, vertically, until you get to the next section. Another (more obvious) way is font size, as demonstrated by the top left headline. A third way is the use of center alignment for Opinion articles. Everything else is right-aligned, and the disruption of the rhythm created by this alignment is what sets off the section as important.

Balance:

We noticed some imbalance in WSJ.com’s header. The designers seem to have placed all the “extras” in the header on the right side, with nothing on the left to balance it. Subscribe and Sign In links are there, along with a red 50% OFF indicator.

Harmony:

All of the images in WSJ’s layout seem to be of the same 1.5 aspect ratio, despite their varying sizes. This adds a sense of consistency throughout. Also, they tend to use a consistent accent color (a mid-blue) seen in mouse-over transitions and in the Market section’s line graph.

Rhythm:

As I mentioned above, left justification is used almost exclusively throughout. There also seems to be consistent horizontal space between columns and consistent vertical space between vertical elements. As the eye travels down the page, one can see which articles are related through alignment of photos and text, such as the strategy employed with stacked boxes in the business section containing right-aligned photos of the same size surrounded by left-aligned text

Other Case Studies

In getting away from traditional new outlets, we wanted to consider NPR.org, whose news is generally disseminated in audio format, with text being secondary. This website is much simpler than WSJ.com, and after a menu on top, takes advantage of a pattern called “cards” to create a nice sense of rhythm. Each card is the same width with the same amount of space between itself and the next one. Each card is labeled with a category, and most feature a headline, a picture, and a button that allows the user to listen to a story. The type treatment is consistent across roles, so without reading the text, you know what information it’s going to tell you.

Another news website that our group studied which is quite unconventional in terms of visual representation was Slate (www.slate.com). Slate again used reverse contrast but this time, augmented it with scale to add emphasis to the most important article on the front page. To indicate difference in context of the link to the Facebook page as well as the request to disable the Ad Blocker (both of which are lower in hierarchy compared to the main news content), Slate glued thin strips of reverse contrast to the top and bottom of the page. As you scroll down further, there is a clear shift in weight to the top right as the heavy Slate logo stays glued to the top right of the page. This, we thought was an excellent manipulation of balance as users can find the menu and the search option on this ‘heavy’ block.

Al Jazeera, as we studied also had some interesting variations on contrast, emphasis and overall balance across its American, English and Arabic versions. The American version had a visual identity that was quite distant from its English and Arabic counterparts and used scale to indicate hierarchical difference in menu, space to indicate emphasis of the titles and contrast to indicate selected menu item. The English and Arabic version, while more similar at a glance, had some differences in the way they used balance and contrast. The English website was a more Left-to-Right oriented website with the emphatic elements predominantly on the left while the Arabic version followed the opposite trend. However, while the live news update was reverse contrasted, it stayed on the left side of the screen for both versions.

The Guatemalan newspaper Prensa Libre appears well-balanced at the top of the web page, but the design rules do not stay consistent as one scrolls down. In the header, the wide white side bars, use of free space and symmetrical layout create a feeling of balance. The distinctive brush-like font used for “Prensa Libre” contrasts dramatically with the Palatino/ Arial font of the rest of the page. The consistency of the font types, blue/gray colors and balanced arrangement create a sense of harmony. The main content is arranged in three columns of unequal width, with some emphasis given to the headline photo on the upper-left that takes up two columns, and greater emphasis given to the column on the right which is slightly wider than the rest and demarcated with a red line and small red clock symbols highlighting the latest news updates. Since the rest of the text and formatting lines are blue, black or gray, the red contrasts dramatically. The red clock symbols match the one in the drop-down menu, creating a clear consistency. On the other side of the page, the upper-left corner is grounded by a large black box with a simple white outline of a house; our eye is clearly drawn to the homepage link. As we scroll down the page, we see a balanced rhythm of column layout alternating image/ text/ image / text. However, as we scroll further down the page, we hit a shadowed line break where the “headlining news” ends and the “Mas noticias” and “Editorial” sections begin. The right column drops out and the other columns do not realign; instead, we are left with a glaring white space which feels unbalanced. For the first time, we have a left-aligned column of bullet points. The inconsistency is startling – I suppose that it is effective in making us feel like we have moved into another section of the paper.. At the bottom of the page, we hit another shadowed line break and the layout shifts entirely for the “Opinion” section; now we have four equal columns with titles that are center-aligned. If we were to study the “Opinion” section in isolation it would appear well-balanced, but the dramatic shifts in layout between sections destroys the overall harmonicity of the page.

Systems of Hierarchy on the Wall Street Journal Homepage

Color

The Wall Street Journal only uses color to a small extent to create hierarchy and emphasis. However, this creates an even stronger hierarchy and gives more weight and emphasis to certain elements. In About Face Alan Cooper, Robert Reimann, David Cronin and Christopher Noessel describe the different ways of creating hierarchy through color. They state that differences in hue, value, or saturation compared to the overall background or full set of colors used can create hierarchy. An additional hierarchical element is the size of a colored element. As an example less important elements could be less saturated and have less value and hue contrast to the background or overall color scheme. Often just varying one of these properties does the trick.

These patterns are clearly applied when looking at the color elements of the WSJ homepage.
While the homepage uses color minimally, it focuses on blue schemes. Therefore the few red elements represent a strong contrast in hue and stick out. There are also differences in value and saturation. Elements with high saturation and dark elements stick out compared to the overall bright appearance of the homepage and its white background. Bright colors, on the contrary, are sometimes barely noticeable and seem to have even less emphasis than purely black elements. When hovering over certains links or categories the color of the headlines changes to a saturated dark blue tone creating high contrast and emphasize on the element.

Typography

The Wall Street Journal homepage uses various typographic techniques to communicate to their readers such as scale, weight, font families, alignments and style. Although the specifics of the hierarchy change depending on the viewing device, one element is constant, size (realtive terms). The Wall Street Journal uses the font size and style to communicate what information should be viewed first and what information is more important. As the book About Face discusses, humans have the ability to differentiate between objects (e.g.big/small) immediately and draw either connections or distinctions between the two. The Wall Street Journal capitalizes on this and uses a difference in size to allow the reader to naturally sequence the objects and attribute relative importance to them. An important principle to take into account is that using size does however have tradeoffs; by using size (large or small) you make it more difficult for the user to decipher the value of other variables, such as shape. This may very well be the reason that the Wall Street Journal does not have many additional shapes/colors on their website.

Here are the fonts that are used on the the Wall Street Journal homepage. One can tell that they use variations of one font for the header and body of the homepage and a contrasting font for the menu (something with different functionality than the previous two).

Head:chronicle display
Font Body: chronicle ssm
Highlight (bolded): chronicle ssm
Menu: Whitney SSm

Image

The Wall Street Journal homepage places the largest image in the widest center left column, making this the most important element in the hierarchy of the page contents. The images in the center right column add weight and draw readers’ attention to this column despite the fact that it is the smallest column. The smaller text does not outweigh the images in the center right column but the larger text at the upper left does. The image of the chart is less prioritized because it is on the far right.

Similar to the color of other elements the colors of the images vary in hue, value and saturation. Most pictures have a blue tone and only vary in terms of saturation and value. Because of the bright homepage background, darker blue tones tend to stand more out and have stronger emphasis whereas an image with light blue colors is inconspicuous. The biggest picture which is also allocated in the middle of the homepage is further emphasised through its strong hue contrast compared to other pictures and used colors. It is the only element that uses a yellow orange tone and therefore draws additional attention.

Composition (Gestalt)

Dondis discusses balance in composition, pointing out that it can be more dynamic and interesting to create balance with asymmetry. On the Wall Street Journal homepage the outer left and outer right columns are the same width, providing some balance. There is sharpening with the two inner columns which are very different in size. The column on the inner left is much wider than the inner right. Here, it is clear that the inner left column is the most important. If the widths were more subtly different, the balance would be ambiguous, making it more difficult to discern which column is more important in the hierarchy. Sharpening can add interest to visual compositions while still achieving balance. In contrast, ambiguity in compositions violates the Gestalt principle of simplicity.

The felt axis of the homepage is actually in the middle of the screen with the larger inner column’s weight overlapping slightly onto the other side of the axis. This positioning of the larger column creates a sense of balance. This felt axis is also the origin of the primary scanning pattern proposed by Dondis. The WSJ homepage could be seen to follow Dondis’s primary scanning pattern or the more recently proposed f-scanning pattern argued to be the primary scanning pattern for websites. Both of these scanning patterns reflect the behaviors of readers of languages that are written left-to-right.

Objectivity/Subjectivity

These assessments are subjective because the principles of hierarchy are quite abstract and different people may interpret and apply them differently. There is likely to be considerable consistency across different people’s interpretations because of similarities in perception. Some of these similarities may be biological and others cultural. We believe that some people would argue that this assessment is objective because there are clearly established principles of color, typography, and composition and it is possible to apply them correctly or incorrectly. However, due to the fact that there is room for interpretation, and because we believe that everything is influenced by our subjectivity, we see this exercise as subjective.

Class Discussion Questions

What visual metaphors are used to deliver information using hierarchy?

Visual metaphors of physical space, weight, and gravity are used in hierarchy, in particular in achieving balance in composition. In addition, metaphors pertaining to size or order can often indicate importance or the order objects should be consumed in.

Can design hierarchy be measured quantitatively? How so?

Certain aspects of design hierarchy can be measured quantitatively. For example, you could quantitatively measure balance in composition and identify the most important elements by looking at the size (pixels or inches), area, and x and y positions of the elements. Elements such as font size, font weight and design pertaining to the grid system can often be measured to an exact pixel. The measurement may be in accordance with web standards or ones developed by the “brand.”

Can design hierarchy be measured qualitatively? How so?

Design hierarchy can also be measured qualitatively by asking people to provide feedback on which elements stand out to them the most on a page. It would also be possible to develop a qualitative coding scheme or set of categories that could be used to assess hierarchy.

Is it possible to create a universal set of parameters for hierarchy?

As mentioned earlier, the part of a page or composition that is automatically perceived as the most important differs based on culture, in particular based on the directions in which people are accustomed to reading. Taking this into it is may be possible to create some parameters for hierarchy (such as what difference/size equates to) but in short, due to social and design constructs it would be very difficult to create a universal set of parameters.

Color and content

– PequeCiencia

PequeCiencia is the website of an informal science center, whose goal is to motivate children and show them that science is fun and exciting. The website uses a wide variety of saturated hues, probably to imply playfulness, creativity, excitement and dynamism. Nevertheless, such crowded palette might overwhelm users, hindering the communication (carnival effect). One question that comes to mind is whether we have this association with children because respond better to environments using this palette of colors, or maybe this is an unsubstantiated association?
In general, the salient colors of the website are orange and blue. This suggests that the designer was looking to achieve balance by using complementary and warm and cold contrast.

Now, regarding the functionality color has in the conveyance of information we should notice four points: a) Titles follow the characteristic orange of the logo which provides a warm/cold contrast with the blue background, emphasizing them, making them easy to locate and read; b) Subtitles use a brownish tone, which falls within the palette of complementary colors for blue and orange (see image below; c) Plain text (normal text) use a neutral gray that contrasts very well with the light blue of the secondary background, making the text easily legible; d) Links offer the user the option to display more information about specific topics. Their color is the same blue of the main background.
Note: Although, the blues of the palette shown below do not coincide with the blues being used in the website, I think this might have been the intention of the designer.

– BMW

The first impression when looking at the website in the light of color is dominated by the colors of the brand logo of BMW which include the primary color blue, besides white, black, and grey. In addition, the only other primary color besides blue is a dark and highly saturated red which draws the viewer’s attention at the first look.

The color red does not take a lot of space, but it is heavy compared to the light and mainly white background. By that, the red balances the huge white space and draws attention to the middle, right side of the website. The red in combination with the car is used in order to arouse emotions by the viewer for the product. The great differences in hue draw the attention quickly towards the car – which is the product, BMW wants to sell. Besides, the eye is led towards the logo of BMW in the upper right corner, bringing the car and the associated emotions directly in relation with the brand. The red builds a contrast of extension as it is a small amount of red that weighs heavy in a huge white and grey space. Moreover, the color red builds a contrast of saturation to the background which also explains why it draws so much attention.

The second primary color blue was chosen by the designer to emphasize a call to action. At those spaces where the user is supposed to click something, the color blue is used. The blue picks up the color of the BMW logo and represents a complementary contrast to the red of the car. Blue is used as a representation of the sky and creates a cool and clean image.
The third color group is represented by shades of grey, black, and white. Those colors are also based on the color identity of BMW and its logo. The light dark contrast makes the text easy to read and the information quickly available to the user. The differences in value is used as a tool to draw attention to the elements that need to stand out from the background and by that help people to perceive the information quickly and easily. By having those “non-colors” in the background, the website becomes lean and clean.

The website also builds a great example of a cold warm contrast through the use of cold colors as blue and grey on the one side, and the accentuated red on the other side. The color red and the color blue also build a contrast of hue to the background colors (white, black and grey).

Question for discussion:
– Do you think certain colors (or combination of them) have the power to attract/repel certain audiences?
By comparing the two websites, we can conclude that color can be used to address completely different customer groups and helps to transport the brand and its values.

Form and Composition

For this blog post we found 5 interface compositions and identified the 3 most important compositional principles being used in each of them.

TI-83 Calculator – http://i.imgur.com/4Gz8DNG.jpg

Color is used to group together similar keys and also to connect “option” keys to their associated annotations. One can see all the digits are colored white and the operators are blue. The “2nd” key is yellow, which links it up with annotations above other keys like “quit” and “insert.” The Alpha key does the same with green annotations.

Proximity is used both to group together similar keys and to associate certain keys with other interface components. For example the blue keys at the top are used to configure the visualization on the screen directly above them. The digit and operator keys are close to one another and suggest they have similar functions.

Shape is used to show significance of certain keys. Most keys are rectangles with curved edges and are symmetrical in two directions. The arrow navigation keys however are only symmetrical in one direction. This allows the keys to be reoriented and point in a direction which is linked with the key’s function.

Microsoft Paint – http://i.imgur.com/zFGpvFc.png

Proximity is used to group together similar tools. Similar colors are close to one another, as are the shape tools and cut/copy/paste.

Scale is used to emphasize the commonly used tools and items of focus. For example the select marquee tool and the paint brush are frequently used so they are bigger. Likewise, the selected color, which is more important than the color options is larger.

Figure and ground is used to separate tool palettes and the working space. The drawing area has the biggest drop shadow to put that in the fore ground. The home tab has a drop shadow around it to suggest there are more tools behind it in the “view” tab

Vo2 Advertisement – http://i.imgur.com/GGFfRTr.png

Continuation: the athlete’s body, the letters and the triangle all appear continuous despite interruptions.

Space: The main actions of the composition all take place at the center of the canvas, creating tension and excitement.

Figure and ground: It is not easy to determine if the letters, the athlete or the triangle is the figure or the ground. The uncertainty makes a catchy ad composition.

Dashboard – http://i.imgur.com/QzLdb6I.png

Similarity: Similarities in color, shape and rhythm help to group functionalities.

Rhythm: The top and bottom panels have different rhythms, and as a result differentiate their content.

Scale: The top panels are smaller than the ones on the bottom, signifying their different functionalities.

Google Maps Directions – http://i.imgur.com/apzOt3Q.png

Hierarchy is implemented in this interface through the use of planes to encapsulate key information required for navigating which are then positioned to follow the typical web page scanning F-pattern. Color is also an indication of hierarchy where the selected path stands out among the other possible paths on the map.

Emphasis is used to highlight important information in this busy interface which is packed with details. The distinct blue coloring highlights the path selected for directions (on both the navigation pane and on the map), while white is used in the blue panel to identify the mode of transportation (in this case, walking). Other colors such as red and yellow are used to highlight select locations on the map, which contrast with the dull grey and brown coloring of city blocks and streets.

Grouping and Rhythm are used on the navigation pane to identify the various paths the user can take, which are further broken down into steps (which use the same principles) if the user selects a particular path.

Color 1 — Ineffective / Effective Alert Messages

Effective

Slippery floor sign —Yellow is an efficient color in alerting people because it can catch people’s attention easily. Why? Because it’s the color nearest to the light. It’s the color of fire and gold. “Gold will always shine.” Similarly, ”Yellow will always be seen.” In its highest purity it always carries with it the nature of brightness. That’s why it’s efficient in alerting people of dangerous situation. Also, it seems to have the power to compete other colors. From my experience of painting, I know white cannot cover other colors, but yellow can. Maybe that can help yellow stands out when there are many colors.

Biohazardous waste bags — and by extension, the receptacles in which they’re in — are successful examples of efficient alert design. Red is a salient color, associated with the idea of “danger” internationally (and mostly in Western cultures). Biohazardous waste furthermore can contain blood specimens, which is red when outside of the body. The combination of emotional, cultural, and semantic associations with the color red make this an effective alert message.

Ambulance — although not a typical case when considering design, the ambulance serves as a good metaphor for alerting users effectively. Within the context of a crowded space, the ambulance has the hard task of alerting other drivers of its presence and intentions. Other automobiles, sounds from honking and people, etc all serve as elements which take away emphasis from the overall scene. In design, one has to be cautious of using extreme hue, saturation, value, size in conjunction. The ambulance is an extreme case in which it is necessary to have many elements used together in high contrast.

OS X Alert Messages –
Apple encourages developers to employ guidelines when using alert messages. The alert message provides a short, simple summary of the error or condition that summoned the alert. The informative text provides a fuller description of the situation. Buttons for addressing the alert appear at the bottom of the dialog. The app icon appears to the left of the text and shows users which app is displaying the alert. The rightmost button in the dialog, the action button, confirms the alert message text. This button stands out with the use of blue on a gray background.

Ineffective

Please Keep Off the Grass — Green is always used in the sign of reminding people not getting in the grass. I think people choose this because they don’t want to break the beauty of grass. Also, they may not think red is the color should be used here because red seems to mean things that really need to be prohibited seriously. However, it actually didn’t support delivering the message. A sign with the description of the history of the grassland can be green, too. In terms of green itself, it’s not an alerting color. On the opposite, as the color of trees and mountains, green is the color the eyes are comfortable with. Another critical problem here is that there’s no contrast between the sign and grass. How can people see a dark green from a light one at once, or tell a light green from a dark one? Here, green seems not to be the color of alerting people, but the color to maintain the beauty of grass. Only the words itself function as alerting.

Darwinator — This is a site which allows users to pitch project ideas. The main action during the initial stage is to complete a submission. The snapshot I have provided shows the page after a user has completed a submission. The ineffective qualities have to do with the inability to draw attention to important events. There is no hierarchy of text and there are two competing color schemes—i.e., orange versus green which are both high value objects as compared to the grey scale background. The completion page ought to alert the user that they have completed the submission. However, the user is left unaware of these changes.

Safety Signs — There are two subjects represented within the content of this sign: (1) safety, and (2) flammable materials. The color green is commonly associated with safety, lack of alarm, and calm. Yet, flammable materials are not. Flammable materials are often associated with danger, caution, colors of red and (sometimes) yellow. Having these two bits of content presented on the same sign allows for a false sense of security when maneuvering around these flammable materials.

Windows Alert Messages – Windows alerts lack consistency. The same dialog boxes used for alerts are also used for error messages and updates. The use of color for the alert icon is meant to stand out, but the action button does not. The alert may imply there is a problem, but the solution is not readily apparent. Messages are often ambiguous or absent.
