In this chapter, perception and empirical research are introduced. These are both ways in which a designer can consider how a reader will respond to visual communication.
Perception: the process of comprehending the world around us (47)
Visual perception is influenced by how we think because:
-We search for FOCAL POINTS: the things that immediately catch your eye and allow you to give meaning to the situation
-When “the field is homogenous” or there is a “repetitious pattern” readers often cannot distinguish what is important or even what to look at (47)
-We draw on past experience: when looking at an ambiguous image, we place what it is through things we have seen before.
-This can include using your education, social life, and cultural background to place what an image is
-Our perception is influenced by the task we are trying to accomplish. We tend to ignore things that are unimportant for the goal we are trying to complete.
The visual field is our range of vision that in any perceptual moment will likely include an array of shapes, lines, colors, patterns and textures (50)
-Our perception of an image can be altered by what we see around it.
Gestalt Principles of Design
“Gestalt” means “Form”
-Gestalt principles help to understand the way readers interpret images based on context. There are 2 main principles:
Figure-ground contrast: the way we separate images from each other. (Ex: separating black text from the background of a page)
-Low contrast documents can be hard to read so visual variety helps to over come this. The following help to create contrast:
· Paragraph breaks
· Headings
· Graphic elements
· Icons
· Illustrations
-While figure ground contrast can help to emphasize different points, if not used purposefully it only creates visual noise, or anything that impedes our perceptual response (57)
*Depending on the rhetorical situation, noise can take away from clarity, but in other cases it can add ethos.
Grouping: a tool to add structure to a document and allow readers to efficiently sort through the parts, thus creating visual cohesion.
-Visual groups are created in 3 ways:
-Likeness of form: how similar are the images? (Ex: is it a circle or square?)
-Spatial nearness: how close together are the images or text on the page?
-Division: lines, boxes, shading, etc. that put images or text in groups
*Groups create patterns that help readers to follow the document
Using the Gestalt principles help to achieve clarity, good arrangement and emphasis on important information.
“Using Gestalt principles, then, is a means to an end—adapting visual language to a rhetorical situation” (67).
Empirical Research: seeks to answer questions about how readers respond to design elements (68)
Empirical research helps designers to determine the best way to display the information and enable them to predict how readers will perceive their document. There is universal and contextual empirical research.
-Universal: focuses on one design element at a time, without considering the things surrounding it in the document, and does not take the rhetorical situation into account.
-Contextual: evaluates how successful a document is in its rhetorical situation. This research is usually done through:
· Observation
· Interviews
· Surveys
· Focus groups
