Casting a Wider Net: Using Historical Analysis as a Resource for Design Susan P. Wyche Georgia Institute of Technology College of Computing Human Centered Computing Program “Those who cannot learn from history are doomed to repeat it.” -George Santayana Introduction I used to design glassware for a large manufacture in the Midwest. It was my first job out of college and the multiple layers involved in creating such a mundane and ubiquitous item amazed me. Union disputes, labor’s gendered character, and the rise and fall of Toledo, Ohio, were embedded in this everyday artifact. The company’s management expected direction for new products to come from them, instead I found inspiration combing through products archives, visiting museums, and reading about glassware’s long and rich history. Doing this not only motivated various design ideas it helped me understand the broader meanings that were embedded in products and their production. As computer technology continues to reach more and more into our everyday lives, understanding technology’s past is necessary if we are to understand where it is going. Analyzing technologies’ historical context is not yet standard practice in the human-computer interaction (HCI) community. Novel computational devices and systems are often conceived of in a vacuum separate from their socio-historical context and their developers sometimes fail to acknowledge technologies’ position on a larger historical trajectory. Incorporating historical analysis into current HCI practice would help practitioners reach their larger goal of making technology more useable and create opportunities for more innovative design solutions. In this paper I will argue that technology developers must cast a wider net in terms of the disciplines they draw from to inform design. I will specifically focus on history’s role in developing new technology. Just as ethnography has helped us understand and design for unconscious cultural meanings and uses of technology, historical analysis can help us become more aware of the trends technology may otherwise unthinkingly propagate. HCI is increasingly a focus of interdisciplinary interest drawing from traditional disciplines such as computer science, cognitive science and design, but also from alternative fields ranging from cultural studies to gerontology. However there is a tendency among HCI practitioners to look for theories that are conveniently associated with their research and apply them without examining additional resources. Classic anthropological, sociological and historical texts are increasingly being cited in popular HCI research areas such as domestic technology and online communities. Csikszentmihalyi and Rochberg-Halton’s (1981) The Meaning of Things: Domestic Symbols and the Self has lead to broader acknowledgement that values are intertwined with domestic technology and influenced how we study the home (Bell, Blythe, Gaver, Sengers, & Wright, 2003; Hirsch, Forlizzi, Hyder, Goetz, Stroback, and Kurtz, 2000; Forlizzi & Ford, 2000) Erving Goffman’s The Presentation of Self in Everyday Life standard among researchers studying identify and impression management online (Palem, Salzman, & Youngs, 2000; Golder & Donath, 2004). Ruth Cohen Schwartz’s More Work for Mother More Work for Mother questions the assumption that technology has reduced the amount of time devoted to domestic work. Her argument has become increasingly relevant to an audience outside the science and technology studies community (Edwards and Grinter; 2001, Bell and Kaye, 2002; Bell, G., Blythe M.et al.., 2003). HCI researchers are also drawing from diverse fields to help develop new usercentered research methods. Gaver’s (2001) “cultural probes” were influenced by Situationists’s texts; writings from a collective of artist-provocateurs based out of Paris from the late 1950’s to the early 1960’s.1 I want to extend this practice by proposing that historical analysis-or focusing on the historical development of artifacts and their use- a standard and more rigorous part of the HCI design process. Figure 1.0 This approach parallels Phoebe Senger’s suggestions to incorporate “critical technical practice” into HCI. Drawing from Agre’s (1997) Computation and the Human Experience, Sengers and her colleagues suggest we explore the assumptions that underpin ideas about technology and humanity when developing it (Dourish, Finaly, Sengers, and Wright, 2004). Similarly my goal is to create more space in HCI for critical reflection on its methods and concepts. Sadie Plant’s The Most Radical Gesture: The Situationist International in a Postmodern Age and Guy Debord’s The Society of the Spectacle are excellent resource for learning more about the Situationists. 1 My background in Industrial Design and I am currently a Ph.D. student in Human-Centered Computer program at the Georgia Institute of Technology. My formal training in history is limited to an undergraduate minor, a handful of graduate level courses, and an enthusiastic curiosity. History scholars may suggest my “armchair approach” to understanding history diminishes from the rigor and complexity in their discipline. This may be true, however I do not pretend to be an authority on this vast field of research. Instead, I want to emphasize why HCI practitioners must cast a wider net in terms of the resources used to inform design and work towards increasing dialogues between people thinking about technology’s past and the ones shaping its future. Motivation Computers presence in our daily lives is rapidly growing. They are in the cars we drive, the alarms that wake us up, and the ATM’s where we get cash. I can interact with people in countries I have never visited and chat about topics ranging from how to program in Python to what it means to be a part of “furry” subculture and all of this is mediated by my laptop. Accompanying these drastic changes in how we communicate, access knowledge, and live at home is a level of unparalleled complexity – complexity which can not be answered by any one discipline. Yet, too often the future is narrated by the new technology crowd, many who are so steeped in enlightenment notions of progress and romantic dreams of community and transcendence on the Net that history seems only a deadweight bogging utopia down (Spigel, 2001). Currently, there is a disconnect between the visionaries creating the future and the historians examining the past. HCI has opened its doors cognitive scientist, anthropologist, and industrial designers. I suggest the field open its doors wider to welcome historians and begin to recognize how technologies’ past influences its future. History provides an additional perspective needed to tame the complexities that will accompany technologies increased presence on our daily lives. Not only can historical analyses bring added perspective to technology’s impact on our lives it can inspire innovative design solutions. Geoffrey Nunberg (1996) writes, “Nothing betrays the spirit of an age so precisely as the way it represents the future.” Images of the future are often embedded in notions of the past, or how Lynn Spigel (2001) describes it, “yesterday’s tomorrow.” She suggests there is a reverse logic to designing for the future. Scenarios represent a future supposedly enhanced with new technology but they often fail to acknowledge the socio-historical change that typically occurs with the passage of time. Representations of tomorrow’s domestic environment demonstrate these phenomena. A popular example comes from a Popular Mechanics 1950’s article about “The Home of the Future.” It depicts the quintessential American mother in her plastic furniture filled living room spraying it with a garden hose. The caption reads, “Because all her furniture is waterproof, the housewife of the year 2000 can do her cleaning with a hose.” (Figure 2.0). Two things make this problematic and provide lessons for how to think about technology development today. During the 1950’s, plastic was growing into a major industry and touted as the something that would change everyday life for the better. At the time it was fashionable to imagine a future rich with everything made out of plastic. Some of these visions materialized, while most did not. Today instead of being sleek and streamlined our future is smart and wired. Housewares manufacturers like Sunbeam, LG, and GE (Figure 3.0) are inventing web-enabled kitchen appliances which are receiving a lukewarm reception from users. Similar to a future made out of plastic, smart appliances are the manifestation of our current interest in a popular and new technology. Designing technology that is grounded in users needs rather than what may be a technological fad can help create more useable computational devices. Plastic furniture is uncomfortable to sit in and I do not need to exchange e-mail with my microwave! Analyzing materials’ histories may help designers reflect on why they are developing the technologies they are and conceive of ideas outside what may be technological fads. Figure 2.0 Figure 3.0 Smart Appliances Secondly, the image perpetuates the notion that housework will and should remain women’s work. Fifty years ago the stay at home mom in charge of home upkeep and looking after the kids was more commonplace than it is today. Since then women have increasingly entered the workforce and making housework with synonymous with “women’s work” has arguably marginalized women’s power outside of the home (Weisman, 1992; Wajcman, 1991; Hayden, 1981). Popular media and advertisement possibly help naturalize gendered notions about domestic labor (Lupton, 1993).2 Half a century later similar problems exists in how the future is conceived. Images of tomorrow’s technology are embedded with dated notions about the meaning of family. ASIMO, Honda’s humanoid wonder robot, promises to be what Rosie the robot was to the Jetson’s. However today family is not the Jetson’s and few mimic the one depicted in Honda’s advertisement (Figure 4.0). Paradoxically, this advanced piece of technology is contrasted by a deeply conservative image. Despite an evolving meaning of what constitutes a family driven by the rise of single mothers, the emergence of blended families, and more visible interracial and same-sex families we are presented with an Stephanie Coontz’s research provides an excellent and more detailed analysis of nostalgic images of family. 2 image that is increasingly become a myth.. Dad’s patriarchal appearance, mom with the “What will they think of next?” smirk on her face, even the well-behaved Golden retriever are all mythical stereotypes which according to the most recent census represent a mere 25% of the American population.3 A similar argument can be made regarding Intel and Microsoft’s “Homes of the Future” (Figure 5.0). Like the previous examples these are laden with conservative and nostalgic values about domestic life. These Tudor and Colonial style “McMansions” are laden with white, upper-middle class, suburban values and fail to acknowledge the diversity of users and living arrangement that exist. Incorporating histories of architecture, family, and domestic life into the front-end design processes will make technology developers more conscious of what values they are perpetuating in their work and question which one should be repeated and which ones should be left behind. 3 2000 Census Data available at http://www.census.gov/main/www/cen2000.html Figure 4.0 Honda’s ASIMO Advertisement Figure 5.0 Intel’s vision of the “Home of the Future” Historical Analysis and Design Research In this section I will outline specific contributions historical analysis can make to the HCI design process. Drawing from historical texts, conducting patent searches, and listening to elders’ historical narratives, are provided as support for merging historical analysis in to current HCI design processes. “I-methodology” or “egocentric intuition fallacy” is when technology developers use themselves as the model for users (Oudershorn, 2003). Currently the HCI community is rather homogenous is many senses. It is predominately white, Western, well-educated technically trained, and young to middle-aged. Ethnographic observation has allowed technology developers to become more conscious of how they map their ways of doing things onto the technology they develop thus alienating certain segments of the population. Immersing oneself in the historical texts may allow HCI researchers to reflect on the cultural meaning embedded in technology and distance themselves from technical fields’ disciplinary dogma. Similar to how a historian would investigate old patents to trace changes in technology, HCI practitioners should do so to inform and inspire their work. Searching the United State’s Government’s Online Patent (http://www.uspto.gov/) database reveals hundreds of futuristic ideas for the home. Perhaps these ideas were too far ahead of their time when conceived or they could not be properly developed without today’s technological know-how. An interesting example is U.S. Patent 4,428,085, Frances Gabe Bateson’s design for a “Self-Cleaning Home (Figure 6.0). The sink, shower, toilet and bathtub clean themselves. The bookshelves automatically remove dust and the fireplace carries away ashes. The closet doubles as a washer/drier and dishwashers are embedded in kitchen cabinets. Just pile in dirty dishes, and the next time they are needed they will be cleaned. Despite the academy and industry’s recent attention to future domestic environments little thought has been given how the home of the future will be maintained. Researchers have examined the internet’s role in changing how we will work, entertain, and stay safe at home, but few have asked the how we will keep it clean. Similar to how ethnography has become an accepted part of the HCI design process, patent searches should also become standard. Patents can give insight into what has been done before and broaden the scope of issues being addressed in current research. Figure 6.0 Historical analysis is typically associated with examining artifacts but it can also be used to gather insights into how user behavior has changed over time. Much attention has been devoted to improving the fit between elders, technology, and the built environment (Lundell, Morris, & Intille, 2004; Mynatt, Essa, and Rogers, 2000). This research has demonstrated the importance of understanding elders’ cognitive and anthropometric needs when developing computational devices. I propose extending elder’s roles in the design process by using their narrative accounts to inform design. We ask older adults to recount historically significant stories. (i.e. Where were you when JFK was shot? Do you remember when Neil Armstrong stepped on the moon? ) Why not ask similar questions to inform design? For example, tell me about the first time you logged onto the internet? Has the microwave changed how you prepare meals? How do cellular phones differ from landline phones? Elders’ narrative responses could help us become more conscious of the cycles of technology use and better understand how such patterns shape out assumptions about future designs and the unanticipated consequences that accompany new technologies thus helping providing additional insight into technology as an experience. There is an increased interest in understanding technology as experience within the HCI community (McCarthy & Wright, 2004). Paralleling this is the need to develop research methods that capture the intangible qualities associated with experience. “Cultural probes” (Gaver et al, 1999) is perhaps the most recognized of these techniques. Historical awareness can help in developing additional methods. The “Memory Scrapbook” (Wyche, 2004) demonstrates how novel research tools can emerge from historical awareness. As a part of a larger study examining aging and housework I wanted to elicit stories about how cleaning has changed over time. To do this I found advertisements from Ladies Home Journal, Good Housekeeping, and Sears and Roebuck catalogues from various years between 1910-1984 and placed them into a scrapbook. In addition to creating novel research tool the process of collecting these images increased my awareness of how housework’s gendered nature was portrayed in popular media. The “Memory Scrapbook” (Figure 7.0) was effective in eliciting stories from the past and helping to create a comfortable report between researcher and subject. Elders’ would sing jingles associated with an ad or reminiscence about a product that was no longer available on the market. Several participants had fond memories of the “Fuller Brush Man,” a door-to-door salesman that sold high quality brushes during the early 1920’s to 1950’s. Many liked buying products from a real person. This insight poses questions as to whether buying products on-line is most desirable to older people or should we return to the days of selling items in person. Designing for experience means stepping out of technical, cognitive, and objective research styles the subjectivity embedded in historical analysis may in developing context appropriate technological experiences. Figure 7.0 “Memory Scrapbook” Finally, not only would HCI benefit from the introductions of humanities into its practice, but social scientist would also reap rewards. Academics in the humanities are sometimes accused of writing in dense, inaccessible prose not readily understood by the general public. Merging their work with HCI practice make their theories see less esoteric and more relevant to peoples’ everyday lives if it was incorporated into technology development. Conclusion Computer devices are becoming more and more intertwined with the artifacts that make up our daily lives. What were once mundane artifacts are slowly becoming highly complicated pieces of technology. If the HCI community is to stay true to its goal of making technology more useable is must continue to accept insights from various disciplines including one that seems far removed from the high tech world. HCI has already opened its door to the arts and social science, I suggest HCI rip the door from its hinges and welcome insights from all disciplines ranging from Ethnic Studies, Public Policy, and Theology. HCI should become a disciplinary melting pot, a place where seemingly disparate disciplines come together to examine the complexity that will arise from technology’s increased presence in our lives.
