<\/a>Figure 1 Hurt Report p.278 (1981)<\/p><\/div>\n
Published in January of 1981, the Motorcycle Accident Cause Factors and Identificatio<\/em><\/span>n of Countermeasures Volume 1: Technical Report<\/em>, also known as the \u201cHurt\u201d report after the lead author H.H. Hurt, became an important document for organizations <\/span>and businesses associated with motorcycle safety.\u00a0 <\/span>The report\u2019s <\/span>purpose was the collection of in-depth information and data about real <\/span>cases of motorcycle crashes and the generation of information regardin<\/span>g \u201cthe causes <\/i>of motorcycle accidents and injuries\u2026the effectiveness<\/i> of safet<\/span>y helmets, and other protective equipment\u2026[and] countermeasure<\/i><\/span>s<\/i> [that] must be determined<\/span> which will prevent motorcycle accidents and reduce injuries\u201d (Hurt, Ouellet, and Thom 1).\u00a0 <\/span>Over 400 page<\/span>s long, the report contains a<\/span>n exhausti<\/span>v<\/span>e list <\/span>of both charts and data tables <\/span>but only a few vi<\/span>sual data representations.\u00a0 <\/span><\/b>The report\u2019s <\/span>length, technical language, and la<\/span>ck of visual graphics leave a large section of the average population outside its scope of audience.\u00a0 <\/span>Those audience outsiders wishing to be <\/span>enlightened from such a study must either <\/span>devote a la<\/span>rge amount of their time towards <\/span>understanding the study\u2019s specific language and use of numbers or seek out experts who can summarize the study\u2019s findings.<\/span><\/p>\n <\/p>\n Figure 2 Basic Rider Course p. 20 (2014)<\/p><\/div>\n More recent studies have begun to include more visual data representations, but the language is often still<\/span> outside the scope of a wider audience.\u00a0 <\/span>The recent push toward providing free and <\/span>easily accessible information through the World Wide Web has encouraged multiple organizations and private citizens to fill the information gap between experts and the information curious.\u00a0 <\/span>In the online world of motorcycle information, sites such as webBikeWorld<\/i><\/a> turn the highly technical information presented these reports into brief summaries of the key findings.\u00a0 <\/span>Even still, the information presented lacks the sense of immediacy offered by well-designed data representations.\u00a0 <\/span>According to Ingo Gunther, well-designed visuals allow \u201cthe uninitiated audience to cross into the field of expertise\u201d (qtd. in Perer 173).\u00a0 <\/span>Lines of text summarizing a report, despite being highly informative, are not very engaging.\u00a0 <\/span>In response, many organizations like the Motorcycle Safety Foundation (MSF)<\/a> have created images and diagrams instructing both amateur and expert riders, but one image created by a German safety researcher in Hannover concerning helmet safety has become so popular as to be posted on the Centers for Disease Control and Prevention\u2019s website (CDC)<\/a> and even used in a marketing scheme by a contemporary helmet manufacturer.<\/span><\/p>\n <\/p>\n Figure 3 Dr. Otte’s Helmet Diagram (c. 2008)<\/p><\/div>\n Figure 4 Dr. Otte (c. 2010)<\/p><\/div>\n Professor Dietmar Otte, the creator of the image, is a prominent accident researcher that often makes use of visual diagrams to accompany his data charts, and his notoriety in th<\/span>e field adds a great deal to the helmet diagram\u2019s credibility.\u00a0 <\/span>Oddly though, despite giving clear reference to the creator of the diagram, none of the sources examined <\/span>for this essay<\/span> ac<\/span>tually cite the article by Dr. Otte in which the diagram originates.\u00a0 <\/span>Further investigation has failed to produce a research article written by <\/span>Dr. Otte that includes the diagram, but the CDC does reference the image as being used in the book Proficient Motorcycling <\/i>by D.L. Hough (2008).\u00a0 <\/span>In addition, other helmet diagrams in articles written by Dr. Otte are very similar to the one in question, suggesting that he is indeed its architect.\u00a0<\/span><\/p>\n <\/p>\n Figure 5 Cost Report (co-authored by Dr. Otte) 327 p.52 (1998)<\/p><\/div>\n The lack of an originating document aside, the popularity of the diagram is hard to deny.\u00a0 <\/span>Much of this fame derives from its immediate approachabilit<\/span>y.\u00a0 <\/span>In contrast to the confusing data tables and images of the \u201cHurt\u201d report, Dr. Otte\u2019s diagram can be understood almost instantly, due in large part to its simplicity.\u00a0 <\/span>The single image maintains almost all of the data required to understand the image; the numbers\u2019 reference to impact percentages is the only missing context and is typically discussed in the webpage\u2019s text.\u00a0 <\/span>No separate data table is required and no legend or key must share the visual space.\u00a0 <\/span>Aiding the simplicity is the limit to three data points: the mirrored diagram of the helmet itself created with solid lines, the grid pattern created by dotted lines, and the percentages presented within the grid spaces.\u00a0 <\/span>The mirrored diagram acts as a parallel image, which is prudent as \u201ccomparisons are usually more effective when the information is adjacent in space rather than stacked in time\u201d (Tufte 81).\u00a0 <\/span>The limit on data points leaves the image, which is typically presented in a small size around 468 x 207 pixels, lean on stimulus, allowing for a faster move from \u201cfeature processing\u201d to \u201cpattern\u201d recognition to perceiving \u201cobjects\u201d (Ware 10-11).\u00a0 <\/span>Plenty of other data points could have been included with the visual, such as number and type of injuries riders suffered from impacts to certain zones and the damage to the helmet in each zone, but each level of additional data would have slowed the recognition process and possibly required an increase in the diagram\u2019s size.<\/span><\/p>\n <\/p>\n Figure 6 CDC’s version of Dr. Otte’s diagram (2012)<\/p><\/div>\n This is not to say, however, that the image is perfect. Dr. Otte\u2019s diagram has been altered in multiple ways for multiple reasons.\u00a0 <\/span>The image used by the CDC has been sharpened, fixing the original diagram\u2019s appearance of having been a fifth generation copy.\u00a0 <\/span>The CDC also changed the color of the dotted lines forming the zone grid to blue, creating a greater deal of contrast between the zone grid and the drawing of the helmet.\u00a0 <\/span>Finally, the CDC created a grayscale background, allowing the helmets to appear as solid images instead of empty space. While it is true that \u201cas the graphical features get larger, so the need for extreme luminance contrast declines\u201d the inverse is also true (Ware 75).\u00a0 <\/span>Because the diagram is often used in its small native resolution, the added use of contrast in the CDC version of Dr. Otte\u2019s diagram is a fruitful amendment.<\/span><\/p>\n <\/p>\n Despite these changes, the CDC\u2019s version of the image does not alter the initial rhetorical impression of Dr. Otte\u2019s original diagram. The CDC uses the cleaned up version of Otte\u2019s diagram on their \u201cMotorcycle Safety Guide: Prevention that works\u201d <\/a>webpage. Statement after statement on the site comes with a reference to a plurality of studies; much of the information is based on correcting faulty information regarding helmets that continue to exist in motorcycle culture, \u201cThere are no negative health effects from helmet use. Helmets do not restrict a rider\u2019s ability to hear important sounds or to see a vehicle in the next lane\u201d (CDC). In connection with the rhetorical position of Dr. Otte\u2019s diagram, a simple statement of a full-face helmet\u2019s superior protection is presented, keeping with the more objective style found in the Hurt report, \u201cThe partial coverage helmet is certainly more effective than no helmet at all, but its effectiveness is significantly below that of the full and full facial coverage helmets\u201d (Hurt, Ouellet, and Thom 295).<\/span><\/p>\n <\/p>\n Figure 7 Main Biker Network web forum image with “pop out” highlighting (2014)<\/p><\/div>\n In contrast, the version of the diagram used as part of an argument in favor of full-face helmets on a web forum for motorcycle riders in Maine makes a much stronger rhetorical impression in favor of full-face helmets; the author of the altered version of the diagram is not given (Dearborn).\u00a0 <\/span>Instead of making simple changes to the diagram to clean up the image, this version highlights in yellow the zones of the helmet only covered by full-face helmets. This in turn creates a pop-out effect, \u201csomething that pops out can be seen in a single eye fixation and experiments show that processing to separate a pop-out object from its surroundings actually takes less than a tenth of a second\u201d (Ware 29).\u00a0 <\/span>The rhetorical purpose is abundantly clear.\u00a0 <\/span>Instead of relying on the viewer to make their own assessment of the data, the viewer is supplied with a pop-out image, directing their focus to the percentage of impacts only protected by a full-face helmet.<\/span><\/p>\n <\/p>\n Figure 8 Emotional appeal image from bmwdean.com. While images of injury and death are currently often used as warnings of danger, this was not always the case. See Rachael Winterling and Sarah Lovin’s essay on post-mortem photography<\/a> for a discussion on an alternate use of death’s visage.<\/p><\/div>\n Other websites use Dr. Otte\u2019s diagram in a much more direct way, employing the visual field as<\/span> a rhetorical tool to suggest that anything short of a full-face helmet is no helmet at all.\u00a0 <\/span>Jeff Dean\u2019s site bmwdean.com<\/i><\/a> places Dr. Otte\u2019s diagram in a series of visuals that also include a helmet with crash damage to the section protecting the chin and face and a graphic image of a crash survivor wrapped in bandages and attached to a device preventing his head from turning.\u00a0\u00a0<\/span>Text does accompany the images, but the argument being made is easily understood without reading a word.\u00a0 <\/span>One company that produces motorcycle helmets, Icon, even made use of the diagram by <\/span>painting it onto one of their helmets.\u00a0 <\/span>While the image is not presented anywhere on Icon\u2019s store website, it should be noted that Icon produces only full-face helmets.\u00a0 <\/span>The creation of a helmet that prominently displays the statistics provided by Dr. Otte, even if it never finds its way onto Icon\u2019s own s<\/span><\/span>tore website, can only help Icon\u2019s sales. The appearance of such a rhetorical visual on multiple motorcycle blogs suggests to the online motorcycle <\/span><\/span>community that Icon is a <\/span><\/span>company <\/span><\/span>tha<\/span><\/span>t takes rider safety\u00a0<\/span><\/span>as its main concern.<\/span><\/span><\/p>\n Figure 9 Icon helmet (2012)<\/p><\/div>\n <\/p>\n The popularity surrounding Dr. Otte\u2019s image suggests a couple of things worth mentioning concerning visual data representatio<\/span>n.\u00a0 <\/span>Chiefly, government and private organizations concerned with safety would do well to understand why this simple diagram remains popular.\u00a0 <\/span>Convincing people to take actions in their own best interest is not always as easy as one would assume.\u00a0 <\/span>A human tendency to resent authoritative decrees often runs afoul of human health promotions.\u00a0 <\/span>Dry public service announcements, while often successful on some level, are vastly improved if the message promoted is both accepted and reinforced by a portion of the public.\u00a0 <\/span>The popularity of Dr. Otte\u2019s diagram proves that an easily understood visual diagram can move beyond a simple statement of safety and on to the front lines of a cultural argument.\u00a0 <\/span>Such a simple diagram will not bring about a switch to universal use of full-face helmets, but more people are going to be aware of the diagram\u2019s data implications because of its wide reception.<\/span><\/p>\n <\/p>\n Second, exceedingly active members of the public, other government entities, and private entities that accept and promote a government or private message are not above altering visual data representations for their own purposes.\u00a0 <\/span>Such purposes can be as altruistic as the CDC\u2019s subtle improvements to Dr. Otte\u2019s diagram, which were meant to improve its readability without altering its rhetorical purpose.\u00a0 <\/span>In contrast, a purpose might be only mildly altruistic, like Icon\u2019s creation of an actual helmet painted to match Dr. Otte\u2019s diagram.\u00a0 <\/span>Such a move, while still promoting safety, necessarily promotes Icon\u2019s own business.\u00a0 <\/span>Others still may simply attempt to add more emphasis to the message by altering the diagram in ways meant to promote one clear message; they may also attempt to change the rhetorical situation in which the diagram is found by placing it amongst other images that emphasize their message. Clearly there exists in the public a large promotional force, and safety organizations would do well to employ the talents of such communities. \u00a0Creative and simple visual data representations that are easily understood and adapted are the key.<\/span><\/p>\n <\/p>\n <\/p>\n <\/p>\n Works Cited<\/span><\/p>\n Centers for Disease Control and Prevention. \u201cMotorcycle Safety Guide: Prevention that Works.\u201d CDC.gov<\/i>.
