ddressing a Performance Issue (Picture Courtesy: http://www.appliancedesign.com/AM/Home/Images/cont_figure1_large.jpg) Justification On searching for a visual example for a universal design related to instruction, I came across the above picture that explains in layman terms what single and twin rotary compressors used in air-conditioning or refrigeration actually are. When a salesperson sells such a unit to a buyer who knows nothing about the engineering of refrigerators, terms such as rotary compressor are difficult to comprehend. Although in the above picture there is a spelling error in which ‘single’ is miss-spelt as ‘signal’, the visual depiction is simple enough and conveys to the beholder what twin and single rotary compressors actually are, and how they function. I was able to identify the spelling mistake from the graphic representation itself. Challenge Activity page 25 This chapter discusses the different between performance support visuals and educational visuals. Skim through the book and the Companion Website for this book at http://www.coe.unco.edu/LindaLohr to locate three examples of performance support visuals and three examples of educational visuals. Briefly describe why each image falls into your assigned category. The three performance support visuals described in this chapter include the hamburger machine, how to connect the computer in a classroom setting and informative visual on parking locations. All these visuals are graphic depiction of the actions needed to
accomplish a particular activity. The burger machine allows a buyer to select the burger by size, the visual to connect the computer using the right sequence of steps also enhances performance and the parking instructions’ visual directs the driver to the correct location....
An average person is armed just with the basic artistic skills, and is unable to express visually through graphic art what he or she can with words. Moreover, it is difficult for an average person to combine ‘words and graphics’ for the depiction of a message for an intended audience. An otherwise well informed and educated person may come up with difficult to comprehend visual expressions which do not emphasize the crux of the intended message. The whole purpose of the message may be missed resulting in incomplete or erroneous comprehension by the intended audience or end-user. The common belief that anything depicted through visual art is ‘easy’ also confounds the problem through this misconception as does the fear of inadequacy in handling modern tools of visual expression.
How does the book help you overcome the plethora of advice out there? Visual comprehension is inherent in all of us as we can easily identify the intended message of a well prepared visual depiction of any facet of life. It may have an instructional purpose or facilitate performance in a particular day-to-day situation. The composition of a visual message is of prime importance and can be simplified by an expert visual artist to achieve its end result. A visual depiction does not necessarily have to a great piece of art. Instead it should be able to convey its purpose in the most effective manner. This book allows us to identify what is the correct method of expression through visual art.
