			<content:encoded><![CDATA[<p>In the film <em>The Descendents</em>, George Clooney&#8217;s character Matt King wrestles &#8212; sometimes comically &#8212; with new and old choices involving his family and Hawaii. In one case, King decides he wants to meet a rival, both just to meet him and to give him some news; that is, he (at least explicitly) has generally good reason to meet him. Perhaps he even <em>ought</em> to meet him. When he actually does meet him, he cannot just do these things, he also argues with his rival, etc. King&#8217;s unplanned behaviors end up causing his rival considerable trouble.<sup><a href="http://www.deaneckles.com/blog/642_do-what-the-virtuous-person-would-do/#footnote_0_642" id="identifier_0_642" class="footnote-link footnote-identifier-link" title="Perhaps deserved trouble. But this certainly didn&amp;#8217;t play a stated role in the reasoning justifying King&amp;#8217;s decision to meet him.">1</a></sup></p>
<p>This struck me as related to some challenges in formulating what one should do &#8212; that is, in the &#8220;practical reasoning&#8221; side of ethics.</p>
<p>One way of getting practical advice out of virtue ethics is to say that one should do what the virtuous person would do in this situation. On its face, this seems right. But there are also some apparent counterexamples. Consider a short-tempered tennis player who has just lost a match.<sup><a href="http://www.deaneckles.com/blog/642_do-what-the-virtuous-person-would-do/#footnote_1_642" id="identifier_1_642" class="footnote-link footnote-identifier-link" title="This example is first used by Gary Watson (&amp;#8220;Free Agency&amp;#8221;, 1975) and put to this use by Michael Smith in his &amp;#8220;Internalism&amp;#8221; (1995). Smith introduces it as a clear problem for the &amp;#8220;example&amp;#8221; model of how what a virtuous person would do matters for what we should each do.">2</a></sup> In this situation, the virtuous person would walk over to his opponent, shake his hand, and say something like &#8220;Good match.&#8221; But if this player does that, he is likely to become enraged and even assault his victorious opponent. So it seems better for him to walk off the court without attempting any of this &#8212; even though this is clearly rude.</p>
<p>The simple advice to do what the virtuous person would do in the present situation is, then, either not right or not so simple. It might be right, but not so simple to implement, if part of &#8220;the present situation&#8221; is one&#8217;s own psychological weaknesses. Aspects of the agent&#8217;s psychology &#8212; including character flaws &#8212; seem to license bad behavior and to remove reasons for taking the &#8220;best&#8221; actions.</p>
<p>King and other characters in <em>The Descendents</em> face this problem, both in the example above and at some other points in the movie. He begins a course of action (at least in part) because this is what the virtuous person would do. But then he is unable to really follow through because he lacks the necessary virtues.<sup><a href="http://www.deaneckles.com/blog/642_do-what-the-virtuous-person-would-do/#footnote_2_642" id="identifier_2_642" class="footnote-link footnote-identifier-link" title="Another reading of some of these events in The Descendents is that these characters actually want to do the &amp;#8220;bad behaviors&amp;#8221;, and they (perhaps unconciously) use their good intentions to justify the course of action that leads to the bad behavior.">3</a></sup> We might take this as a reminder of the ethical value to being humble &#8212; to account for our faults &#8212; when reasoning about what we ought to do.<sup><a href="http://www.deaneckles.com/blog/642_do-what-the-virtuous-person-would-do/#footnote_3_642" id="identifier_3_642" class="footnote-link footnote-identifier-link" title="Of course, the other side of such humility is being short on self-efficacy.">4</a></sup> It is also a reminder of how frustrating this can be, especially when one can imagine (and might actually be able to) following through on doing what the virtuous person would do. </p>
<p>One way to cope with these weaknesses is to leverage other aspects of one&#8217;s situation. We can make public commitments to do the virtuous thing. We can change our environment, sometimes by binding our future selves, like Ulysses, from acting on our vices once we&#8217;ve begun our (hopefully) virtuous course of action. Perhaps new mobile technologies will be a substantial help here &#8212; helping us intervene in our own lives in this way.</p>

			<content:encoded><![CDATA[<p>Are the conditions required to assert something conventions? Can they be formalized? Donald Davidson on whether convention is foundational to communication:</p>
<blockquote><p>But Frege was surely right when he said, &#8220;There is no word or sign in language whose function is simply to assert something.&#8221; Frege, as we know, set out to rectify matters by inventing such a sign, the turnstile ⊢&#8217; [sometimes called Frege's 'judgment stroke' or 'assertion sign']. And here Frege was operating on the basis of a sound principle: if there is a conventional feature of language, it can be made manifest in the symbolism. However, before Frege invented the assertion sign he ought to have asked himself why no such sign existed before. Imagine this: the actor is acting a scene in which there is supposed to be a fire. (Albee&#8217;s <em>Tiny Alice</em>, for example.) It is his role to imitate as persuasively as he can a man who is trying to warn others of a fire. &#8220;Fire!&#8221; he screams. And perhaps he adds, at the behest of the author, &#8220;I mean it! Look at the smoke!&#8221; etc. And now a real fire breaks out, and the actor tries vainly to warn the real audience. &#8220;Fire!&#8221; he screams, &#8220;I mean it! Look at the smoke!&#8221; etc. If only he had Frege&#8217;s assertion sign.</p>
<p>It should be obvious that the assertion sign would do no good, for the actor would have used it in the first place, when he was only acting. Similar reasoning should convince us that it is no help to say that the stage, or the proscenium arch, creates a conventional setting that negates the convention of assertion. For if that were so, the acting convention could be put into symbols also; and of course no actor or director would use it. The plight of the actor is always with us. There is no known, agreed upon, publically recognizable convention for making assertions. Or, for that matter, giving orders, asking questions, or making promises. These are all things we do, often successfully, and our success depends in part on our having made public our intention to do them. But it was not thanks to a convention that we succeeded.<sup><a href="http://www.deaneckles.com/blog/623_freges-judgment-stroke/#footnote_0_623" id="identifier_0_623" class="footnote-link footnote-identifier-link" title="Davidson, Donald.

			<content:encoded><![CDATA[<p>When Facebook was sweeping Stanford in Spring 2004, it wasn&#8217;t yet just Facebook &#8212; it was [thefacebook.com]. Many of my friends who were undergrads at Stanford around that time (and shortly after) will still refer to it as &#8220;The Facebook&#8221; or &#8220;the facebook dot com&#8221;. This usage can be a jokey signal to members of the in-group that one was an early user. This also may signal attendance at one of the universities Facebook was available at early on (e.g., Harvard, Stanford, Yale, Columbia).<sup><a href="http://www.deaneckles.com/blog/419_ambiguous-signals-the-facebook/#footnote_0_419" id="identifier_0_419" class="footnote-link footnote-identifier-link" title="Though it is worth noting that by the time of the domain-name change, many more schools had access to Facebook. But I would guess the likelihood of adoption and attachment to the name is lower. Update: see this more detailed timeline of Facebook university launches.">1</a></sup></p>
<p>Of course, this signal can fail for various reasons. The audience may not understand &#8212; may see &#8220;the Facebook&#8221; as a grammatical error. Or widespread attention to Facebook&#8217;s history (say, via a fictionalized movie) may put many people in possession of the ability to use this signal, even though they weren&#8217;t early users and are not alumni at the appropriate universities. </p>
<p>Worse still, for some audiences, this usage might seem to put the speaker in a late-adopting category, rather than an early-adopting one! For example, in <a href="http://www.livestream.com/facebookguests/video?clipId=pla_0da9c42f-9499-4c60-8069-e306dd089fc3&#038;utm_source=lslibrary&#038;utm_medium=ui-thumb">President G. W. Bush&#8217;s visit to Facebook today</a>, he said he is now on &#8220;the Facebook&#8221;. So to many ears, &#8220;the Facebook&#8221; does exactly the opposite of the effects described above.</p>
<p>In fact, at least one friend has had just this experience: she used &#8220;the Facebook&#8221; and got a &#8220;are you a luddite?&#8221; kind of response. To avoid ambiguity (but also subtlety), &#8220;the facebook dot com&#8221; is still available.</p>
<ol class="footnotes"><li id="footnote_0_419" class="footnote">Though it is worth noting that by the time of the domain-name change, many more schools had access to Facebook.

			<content:encoded><![CDATA[<p>TechCrunch and others have been joking about <a href="http://www.techcrunch.com/2009/09/01/developers-be-warned-apple-has-apparently-trademarked-those-shiny-chat-bubbles/">Apple&#8217;s rejection of an app because it uses shiny chat bubbles</a>, which the Apple representative claimed were trademarked:</p>
<p style="padding-left: 30px;">Chess Wars was being rejected after the six week wait [because] the bubbles in its chat rooms are too shiny, and Apple has trademarked that bubbly design. [...] The representative said Stump needed to make the bubbles “less shiny” and also helpfully suggested that he make the bubbles square, just to be sure.</p>
<p><a href="http://www.flickr.com/photos/joestump/3878137873/" title="My chat looks too much like Apple's SMS app by joestump, on Flickr"><img src="http://farm3.static.flickr.com/2575/3878137873_549f5b44df.jpg" width="500" height="375" alt="My chat looks too much like Apple's SMS app" /></a></p>
<p>One thing that is quite striking in this situation is that it is at odds with Apple&#8217;s long history of strongly encouraging third-party developers to follow many UI guidelines &#8212; guidelines that when followed make third-party apps blend in like they&#8217;re native.<sup><a href="http://www.deaneckles.com/blog/201_apples-trademarked-chat-bubbles-source-equivocality-in-mobile-apps-and-services/#footnote_0_201" id="identifier_0_201" class="footnote-link footnote-identifier-link" title="I was led to think this by a commenter on TechCrunch, Dan Grossman, pointing out this long history.">1</a></sup></p>
<p>It&#8217;s important to not read too much into this (especially since we don&#8217;t know what Apple&#8217;s more considered policy on this will end up being), but it is interesting to think about how responsibility gets spread around among mobile applications, services, and devices &#8212; and how this may be different than existing models on the desktop.My sense is that experienced desktop computer users understand at least the most important ways sources of their good and bad experiences are distinguished. For example, &#8220;locomotion&#8221; is a central metaphor in using the Web, as opposed to the conversation and manipulation metaphors of the command line / natural language interfaces and WIMP: we &#8220;go to&#8221; a site (see <a href="http://www.designinginteractions.com/interviews/TerryWinograd">this interview with Terry Winograd</a>, <a href="http://www.designinginteractions.com/downloads/7_1TerryWinograd_H264.mov">full .mov here</a>). The locomotion metaphor helps people distinguish what <em>my</em> computer is contributing and what some distant, third-party &#8220;site&#8221; is contributing.</p>
<p>This is complex even on the Web, but many of these genre rules are currently being all mixed up. Google has Gmail running in your browser but on your computer. Cameraphones are recognizing objects you point them at &#8212; some by analyzing the image on the device and some by sending the device to a server to be analyzed.</p>
<p>This issue is sometimes identified by academics as one of source orientation and source equivocality. Though there has been some great research in this area, there is a lot we don&#8217;t know and the field is in flux: people&#8217;s beliefs about systems are changing and the important technologies and genres are still emerging.</p>
<p>If there&#8217;s one important place to start thinking about the craziness of the current situation of ubiquitous source equivocality is <a href="http://www.stanford.edu/~henretig/Psych_FB/beniger.pdf">&#8220;Personalization of mass media and the growth of pseudo-community&#8221; (1987) by James Beniger</a> that predates much of the tech at issue.</p>

			<content:encoded><![CDATA[<p>Mobile phones are gateways to our most important and enduring relationships with other people. But, like other communication technologies, the mobile phone is psychologically not only a medium: we also form enduring relationships with devices themselves and their  associated software and services (Sundar 2004). While different than  relationships with other people, these human–technology relationships are also importantly social relationships. People exhibit a host of automatic, social responses to interactive  technologies by applying familiar social rules, categories, and norms that are otherwise used in interacting with people (Reeves and Nass 1996; Nass and Moon 2000).</p>
<p>These human–technology relationships develop and endure over time and through radical changes in the situation. In particular, mobile phones are near-constant companions. They take on roles of both medium for communication with other people and independent interaction partner through dynamic physical, social, and cultural environments and tasks. The global phenomenon of mobile phone use highlights both that relationships with people and technologies are inﬂuenced by variable context and that these devices are, in some ways, a constant in amidst these everyday changes.</p>
<h2>Situational variation and attribution</h2>
<p>Situational variation is important for how people understand and interact with mobile technology. This variation is an input to the processes by which people disentangle the internal (personal or device) and external (situational) causes of an social entity’s behavior (Fiedler et al. 1999; Forsterling 1992; Kelley 1967), so this situational variation contributes to the traits and states attributed to human and technological entities. Furthermore, situational variation inﬂuences the relationship and interaction in other ways. For example, we have recently carried out an experiment providing evidence that this situational variation itself (rather than the characteristics of the situations) inﬂuences memory, creativity, and self-disclosure to a mobile service; in particular, people disclose more in places they have previously disclosed to the service, than in  new places (Sukumaran et al. 2009).</p>
<p>Not only does the situation vary, but mobile technologies are increasingly responsive to the environments they share with their human interactants. A system’s systematic and purposive responsiveness to the environment means means that explaining its behavior is about more than distinguishing internal and external causes: people explain behavior by attributing reasons to the entity, which may trivially either refer to internal or external causes. For example, contrast “Jack bought the house because it was secluded” (external) with “Jack bought the house because he wanted privacy” (internal) (Ross 1977, p. 176). Much research in the social cognition and attribution theory traditions of psychology has failed to address this richness of people’s everyday explanations of other ’s behavior (Malle 2004; McClure 2002), but contemporary, interdisciplinary work is elaborating on theories and methods from philosophy and developmental psychology to this end (e.g., the contributions to Malle et al. 2001).</p>
<p>These two developments &#8212; the increasing role of situational variation in human-technology relationships and a new appreciation of the richness of everyday explanations of behavior &#8212; are important to consider together in designing new research in human-computer interaction, psychology, and communication. Here are three suggestions about directions to pursue in light of this:</p>
<p>Design systems that <strong>provide constancy and support through radical situational changes</strong> in both the social and physical environment. For example, we have created a system that uses the voices of participants in an upcoming event as audio primes during transition periods (Sohn et al. 2009). This can help ease the transition from a long corporate meeting to a chat with fellow parents at a child&#8217;s soccer game.</p>
<p><strong>Design experimental manipulations and measure based on features of folk psychology</strong> &#8211;  the implicit theory or capabilities by which we attribute, e.g., beliefs, thoughts, and desires (propositional attitudes) to others (Dennett 1987) &#8212; identified by philosophers. For example, attributions propositional attitudes (e.g., beliefs) to an entity have the linguistic feature that one cannot substitute different terms that refer to the same object while maintaining the truth or appropriateness of the statement. This opacity in attributions of propositional attitudes is the subject of a large literature (e.g., following Quine 1953), but this  has not been used as a lens for much empirical work, except for some developmental psychology  (e.g., Apperly and Robinson 2003). Human-computer interaction research should use this opacity (and other underused features of folk psychology) in studies of how people think about systems.</p>
<p><strong>Connect work on </strong><strong>mental models of systems</strong> (e.g., Kempton 1986; Norman 1988) <strong>to theories of social cognition and fol</strong><strong>k psychology.</strong> I think we can expect much larger overlap in the process involved than in the current research literature: people use folk psychology to understand, predict, and explain technological systems &#8212; not just other people.</p>

			<content:encoded><![CDATA[<p>Increasing valuable annotation behaviors was a practical end of a good deal of work at Yahoo! Research Berkeley. <a href="http://zonetag.research.yahoo.com">ZoneTag </a>is a mobile application and service that suggests tags when users choose to upload a photo (to Flickr) based on their past tags, the relevant tags of others, and events and places nearby. Through social influence and removing barriers, these suggestions influence users to expand and consistently use their tagging vocabulary (Ahern et al. 2006).</p>
<p>Context-aware suggestion techniques such as those used in ZoneTag can increase tagging, but what about users&#8217; motivations for considering tagging in the first place? And how can these motivations for annotation be considered in designing services that involve annotation? In this post, I consider existing work on motivations for tagging, and I use tagging on Facebook as an example of how multiple motivations can combine to increase desired annotation behaviors.</p>
<p>Using photo-elicitation interviews with ZoneTag users who tag, Ames &amp; Naaman (2007) present a two factor taxonomy of motivations for tagging. First, they categorize tagging motivations by <em>function</em>: is the motivating function of the tagging organizational or communicative? Organizational functions include supporting search, presenting photos by event, etc., while communicative functions include when tags provide information about the photos, their content, or are otherwise part of a communication (e.g., telling a joke). Second, they categorize tagging motivations by intended audience (or <em>sociality</em>): are the tags intended for my future self, people known to me (friends, family, coworkers, online contacts), or the general public?</p>
<div class="wp-caption alignright" style="width: 334px"><a href="http://yahooresearchberkeley.com/blog/2007/04/09/why-we-tag/"><img title="Table 1 from Ames &amp; Naaman" src="http://yahooresearchberkeley.com/blog/wp-content/uploads/2007/04/taxonomy%20cameraready.jpg" alt="Taxonomy of motivations for tagging from Ames &amp; Naaman" width="324" height="186" /></a><p class="wp-caption-text">Taxonomy of motivations for tagging from Ames &amp; Naaman</p></div>
<p>On Flickr the function dimension generally maps onto the distinction between functionality that enables and is prior to arriving at the given photo or photos (organization) and functionality applicable once one is viewing a photo (communication). For example, I can find a photo (by me or someone else) by searching for a person&#8217;s name, and then use other tags applied to that photo to jog my memory of what event the photo was taken at.</p>
<p>Some Flickr users subscribe to RSS feeds for public photos tagged with their name, making for a communication function of tagging &#8212; particularly tagging of people in media &#8212; that is prior to &#8220;arriving&#8221; at a specific media object. These are generally techie power users, but this can matter for others. Some less techie participants in our studies reported noticing that their friends did this &#8212; so they became aware of tagging those friends&#8217; names as a communicative act that would result in the friends finding the tagged photos.</p>
<p>This kind of function of tagging people is executed more generally &#8212; and for more than just techie power users &#8212; by Facebook. In tagging of photos, videos, and blog posts, tagging a person notifies them they have been tagged, and can add that they have been tagged to their friends&#8217; News Feeds. This function has received a lot of attention from a privacy perspective (and it should). But I think it hints at the promise of making annotation behavior fulfill more of these functions simultaneously. When specifying content can also be used to specify recipients, annotation becomes an important trigger for communication.</p>

			<content:encoded><![CDATA[<p>Today I&#8217;m attending the Social Mobile Media Workshop at Stanford University. It&#8217;s organized by researchers from Stanford&#8217;s <a href="http://hstar.stanford.edu">HStar</a>, Tampere University of Technology, and the Naval Postgraduate School. What follows is some still jagged thoughts that were prompted by the presentation this morning, rather than a straightforward account of the presentations.<sup><a href="http://www.deaneckles.com/blog/22_producing-consuming-annotating-social-mobile-media-workshop-stanford-university/#footnote_0_22" id="identifier_0_22" class="footnote-link footnote-identifier-link" title="Blogging something at this level of roughness is still new for me&amp;#8230;">1</a></sup></p>
<p>A big theme of the workshop this morning has been transitions among production and consumption &#8212; and the critical role of annotations and context-awareness in enabling many of the user experiences discussed. In many ways, this workshop took me back to thinking about mobile media sharing, which was at the center of a good deal of my previous work. At <a href="http://yahooresearchberkeley.com/">Yahoo! Research Berkeley</a> we were informed by Marc Davis&#8217;s <a href="http://garage.sims.berkeley.edu/">vision</a> of enabling &#8220;the billions of daily media consumers to become daily media producers.&#8221; With <a href="http://zonetag.research.yahoo.com/">ZoneTag</a> we used context-awareness, sociality, and simplicity to influence people to create, annotate, and share photos from their mobile phones (Ahern et al. 2006, 2007).</p>
<p>Enabling and encouraging these behaviors (for all media types) remains a major goal for designers of participatory media; and this was explicit at several points throughout the workshop (e.g., in Teppo Raisanen&#8217;s broad presentation on persuasive technology). This morning there was discussion about the technical requirements for consuming, capturing, and sending media. Cases that traditionally seem to strictly structure and separate production and consumption may be (1) in need of revision and increased flexibility or (2) actually already involve production and consumption together through existing tools. Media production to be part of a two-way communication, it must be consumed, whether by peers or the traditional producers.</p>
<p>As an example of the first case, Sarah Lewis (Stanford) highlighted the importance of making distance learning experiences reciprocal, rather than enforcing an asymmetry in what media types can be shared by different participants. In a past distance learning situation focused on the African ecosystem, it was frustrating that video was only shared from the participants at Stanford to participants at African colleges &#8212; leaving the latter to respond only via text. A prototype system, <a href="http://stanford.edu/~sarahl/mobltzDemo.html">Mobltz</a>, she and her colleagues have built is designed to change this, supporting the creation of channels of media from multiple people (which also reminded me of <a href="http://www.google.com/url?sa=t&#038;ct=res&#038;cd=1&#038;url=http%3A%2F%2Fwww.kyte.tv%2F&#038;ei=04STSNnoMoGOsQOw8PCgCg&#038;usg=AFQjCNEHzEdnrJ59GhuzDvFWSbYvIxjQtg&#038;sig2=HJnaP8ZAMxt8t110i39kmw">Kyte.tv</a>).</p>
<p>As an example of the second case, Timo Koskinenen (Nokia) presented a trial of <a href="http://news.softpedia.com/news/Mobile-Journalism-Application-from-Nokia-and-Reuters-69034.shtml">mobile media capture tools for professional journalists</a>. In this case the work flow of what is, in the end, a media production practice, involves also consumption in the form of review of one&#8217;s own materials and other journalists, as they edit, consider what new media to capture.</p>
<p>Throughout the sessions themselves and conversations with participants during breaks and lunch, having good annotations continued to come up as a requirement for many of the services discussed. While I think our ZoneTag work (and the free <a href="http://developer.yahoo.com/yrb/zonetag/suggestedtags.html">suggested tags Web service API</a> it provides) made a good contribution in this area, as has a wide array of other work (e.g., von Ahn &#038; Dabbish 2004, licensed in <a href="http://images.google.com/imagelabeler/">Google Image Labeler</a>), there is still a lot of progress to make, especially in bringing this work to market and making it something that further services can build on.</p>

			<content:encoded><![CDATA[<p>Much of current human-computer interaction (HCI) research focuses on novice users in &#8220;walk-up and use&#8221; scenarios. I can think of three major causes for this:</p>
<ol>
<li>A general shift from examining non-discretionary use to discretionary use</li>
<li>How much easier it is to find (and not train) study participants unfamiliar with a system than experts (especially with a system that is only a prototype)</li>
<li>The push from practitioners in the direction, especially with the advent of the Web, where new users just show up at your site, often deep-linked</li>
</ol>
<p>This focus sometimes comes in for criticism, especially when #2 is taken as a main cause of the choice.</p>
<p>On the other hand, some research threads in HCI continue to focus on expert use. As I&#8217;ve been reading a lot of research on both human performance modeling and situated &#038; embodied approaches to HCI, it has been interesting to note that both instead have (comparatively) a much bigger focus on the performance and experience of expert and skilled use.</p>
<p>Grudin&#8217;s &#8220;Three Faces of Human-Computer Interaction&#8221; does a good job of explaining the human performance modeling (HPM) side of this. HPM owes a lot to human factors historically, and while <em>The Psychology of Human-Computer Interaction</em> successfully brought engineering-oriented cognitive psychology to the field, it was human factors, said Stuart Card, &#8220;that we were trying to improve&#8221; (Grudin 2005, p. 7). And the focus of human factors, which arose from maximizing productivity in industrial settings like factories, has been non-discretionary use. Fundamentally, it is hard for HPM to exist without a focus on expert use because many of the differences &#8212; and thus research contributions through new interaction techniques &#8212; can only be identified and are only important for use by experts or at least trained users. Grudin notes:</p>
<blockquote><p>A leading modeler discouraged publication of a 1984 study of a repetitive task that showed people preferred a pleasant but slower interaction technique—a result significant for discretionary use, but not for modeling aimed at maximizing performance.</p></blockquote>
<p>Situated action and embodied interaction approaches to HCI, which Harrison, Tatar, and Senger (2007) have called the &#8220;third paradigm of HCI&#8221;, are a bit different story. While HPM research, like a good amount in traditional cognitive science generally, contributes to science and design by assimilating people to information processors with actuators, situated and embodied interaction research borrows a fundamental concern of ethnomethodology, focusing on how people actively make behaviors intelligible by assimilating them to social and rational action.</p>
<p>There are at least three ways this motivates the study of skilled and expert users:</p>
<ol>
<li>Along with this research topic comes a methodological concern for studying behavior in context with the people who really do it. For example, to study publishing systems and technology, the existing practices of people working in such a setting of interest are of critical importance.</li>
<li>These approaches emphasize the skills we all have and the value of drawing on them for design. For example, Dourish (2001) emphasizes the skills with which we all navigate the physical and social world as a resource for design. This is not unrelated to the first way.</li>
<li>These approaches, like and through their relationships to the participatory design movement, have a political, social, and ethical interest in empowering those who will be impacted by technology, especially when otherwise its design &#8212; and the decision to adopt it &#8212; would be out of their control. Non-discretionary use in institutions is the paradigm prompting situation for this.</li>
</ol>
<p>I don&#8217;t have a broad conclusion to make. Rather, I just find it of note and interesting that these two very different threads in HCI research stand out from much other work as similar in this regard. Some of my current research is connecting these two threads, so expect more on their relationship.</p>

			<content:encoded><![CDATA[<p>As I&#8217;ve <a href="http://www.deaneckles.com/blog/13_texting-4-health-conference-in-review/">blogged </a>before, I spoke at the <a href="http://www.texting4health.org/">Texting 4 Health conference</a> on the topic of research methods for mobile messaging. One method I covered was an interesting use of Wizard of Oz techniques for designing mobile services. I&#8217;ve since started getting some of this material in writing for the Texting 4 Health book. Here is a taste of that material, minus the health-specific focus and examples.<br />
&#8212;&#8212;-<br />
Just like the famous Wizard of Oz, one can simulate something impressive with a just a humble person behind the curtain &#8212; and use this simulation to inform design decisions. When using a <a href="http://www.usabilitynet.org/tools/wizard.htm">Wizard of Oz technique</a> to study a prototype, a human “wizard” carries out functions that, in a deployed application or service, would be handled by a computer. This can allow evaluating a design without fully building what can be expensive back-end parts of the system (Kelley 1984). The technique is often used in recognition-based interfaces, but it also has traditional applications to identifying usability problems and carrying out experiments in which the interaction is systematically manipulated.</p>
<p>Wizard of Oz techniques are well suited to prototyping mobile services, especially those using mobile messaging (SMS, MMS, voice messaging). When participants send a request, a wizard reads or listens to it and chooses the appropriate response, or just creates it on-the-fly. Since all user actions in mobile messaging are discrete messages and (depending on the application) the user can often tolerate a short delay, a few part-time wizards, such as you and a colleague, can manage a short field trial. As you&#8217;ll see, <strong>this can be used for purposes beyond many traditional uses of a Wizard of Oz.</strong></p>
<p><strong>Probing photo consumption needs with realistic motivations</strong><br />
One use for this technique in designing a mobile messaging service is a bit like a diary study. In designing an online and mobile photography service, we wanted to better understand what photos people wanted to view and what prompted these desires.<sup><a href="http://www.deaneckles.com/blog/16_using-a-wizard-of-oz-technique-in-mobile-service-design-probing-with-realistic-motivations/#footnote_0_16" id="identifier_0_16" class="footnote-link footnote-identifier-link" title="This study was designed and executed at Yahoo! Research Berkeley by Shane Ahern, Nathan Good, Simon King, Mor Naaman, Rahul Nair, and myself.">1</a></sup>  Instead of just making diary entries, participants actually made voice requests to the system for photos – and received a mobile message with photos fitting the request in return. We didn’t need to first build a robust system that could do this; a few of us served as wizards, listening to the request, doing a couple manual searches, and choosing which photos to return on demand. Though this can be done with a normal voice call, we used a mobile client application that also recorded contextual information not available via a normal voice call (e.g. location), so that participants could make context-aware requests as they saw fit (e.g. &#8220;I want too see photos of this park&#8221;)</p>
<p>In this case, we didn’t plan to (specifically) create a voice-based photo search system; instead, like a diary study, this technique served as a probe to understand what we should build. As a probe it provided realistic motivations for submitting requests, as the request would actually be fulfilled. This design research, in additional to other interviews and a usability study, informed our creation of <a href="http://zurfer.research.yahoo.com">Zurfer</a>, a mobile application that supports exploring and conversing around personalized, location-aware channels of photos.<br />
It is great if the Wizard of Oz prototype is quite similar to what you later build, but it can yield valuable insights even if not. Sometimes it is precisely these insights that can lead you to substantially change your design.</p>
<p>This study design can apply in designing many mobile services. As in our photos study, participants can be interviewed about the trigger for the requests (why did they want that media or information) and how satisfied they were with the (human-created) responses.<sup><a href="http://www.deaneckles.com/blog/16_using-a-wizard-of-oz-technique-in-mobile-service-design-probing-with-realistic-motivations/#footnote_1_16" id="identifier_1_16" class="footnote-link footnote-identifier-link" title="Participants were informed that their requests would be seen by our research staff. Anonymization and strict limits of who the wizards are is necessary to protect participants&rsquo; privacy. Even if participants are not informed that a wizard is creating the responses until they are debriefed after the experiment, participants can nonetheless be notified that their responses are being reviewed by the research team.">2</a></sup></p>

			<content:encoded><![CDATA[<p>Yes, that spells ASSIST.</p>
<p>Check out <a href="http://www.darpa.mil/baa/pdfs/baa04-38PIP.pdf">this call for proposals</a> from <a href="http://en.wikipedia.org/wiki/DARPA">DARPA</a> (also see <a href="http://www.wired.com/politics/security/news/2004/09/64911">Wired News</a>). This research program is designed to create and evaluate systems that use sensors to capture soldiers&#8217; experiences in the field, thus allowing for (spatially and temporally) distant review and analysis of this data, as well as augmenting their abilities while still in the field.</p>
<p>I found it interesting to consider differences in requirements between this program and others that would apply some similar technologies and involve similar interactions &#8212; but for other purposes. For example, two such uses are (1) everyday life recording for social sharing and memory and (2) rich data collection as part of ethnographic observation and participation.</p>
<p>When doing some observation myself, I strung my cameraphone around my neck and used <a href="http://waymarkr.com">Waymarkr</a> to automatically capture a photo every minute or so.  Check out <a href="http://flickr.com/photos/deaneckles/sets/72157594492650061/">the results</a> from my visit to a flea market in San Francisco.</p>
<p><img src="http://waymarkr.com/media/wearable/hat2.jpg" /><img src="http://waymarkr.com/media/wearable/bro1.jpg" /></p>
<p><a href="http://waymarkr.com/wear/">Photos of two ways to wear a cameraphone from Waymarkr</a>. Incidentally, Waymarkr uses <a href="http://developer.yahoo.com/yrb/zonetag/index.html">the cell-tower-based location API</a> created for <a href="http://zonetag.research.yahoo.com">ZoneTag</a>, a project I worked on at <a href="http://www.yahooresearchberkeley.com">Yahoo! Research Berkeley</a>.</p>
<p>Also, for a use more like (1) in a fashion context, see <a href="http://www.blackboxnation.com/bim/blogginginmotionpurse.html">Blogging in Motion</a>. This project (for <a href="http://developer.yahoo.net/hackday/">Yahoo! Hack Day</a>) created a &#8220;auto-blogging purse&#8221; that captures photos (again using ZoneTag) whenever the wearer moves around (sensed using GPS).</p>
