Producing, consuming, annotating (Social Mobile Media Workshop, Stanford University)
Today I’m attending the Social Mobile Media Workshop at Stanford University. It’s organized by researchers from Stanford’s HStar, 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.1
A big theme of the workshop this morning has been transitions among production and consumption — 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 Yahoo! Research Berkeley we were informed by Marc Davis’s vision of enabling “the billions of daily media consumers to become daily media producers.” With ZoneTag 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).
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’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.
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 — leaving the latter to respond only via text. A prototype system, Mobltz, 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 Kyte.tv).
As an example of the second case, Timo Koskinenen (Nokia) presented a trial of mobile media capture tools for professional journalists. 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’s own materials and other journalists, as they edit, consider what new media to capture.
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 suggested tags Web service API it provides) made a good contribution in this area, as has a wide array of other work (e.g., von Ahn & Dabbish 2004, licensed in Google Image Labeler), 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.

Update your Facebook status: social comparison and the availability heuristic
[Update: This post uses an older Facebook UI as an example. Also see more recent posts on activity streams and the availability heuristic.]
Over at Captology Notebook, the blog of the Stanford Persuasive Technology Lab, Enrique Allen considers features of Facebook that influence users to update their status. Among other things, he highlights how Facebook lowers barriers to updating by giving users a clear sense of something they can right (“What are you doing right now?”).
I’d like to add another part of the interface for consideration: the box in the left box of the home page that shows your current status update with the most recent updates of your friends.
This visual association of my status and the most recent status updates of my friends seems to do at least a couple things:
Influencing the frequency of updates. In this example, my status was updated a few days ago. On the other hand, the status updates from my friends were each updated under an hour ago. This juxtaposes my stale status with the fresh updates of my peers. This can prompt comparison between their frequency of updates and mine, encouraging me to update.
The choice of the most recent updates by my Facebook friends amplifies this effect. Through automatic application of the availability heuristic, this can make me overestimate how recently my friends have updated their status (and thus the frequency of status updates). For example, the Facebook friend who updated their status three minutes ago might have not updated to three weeks prior. Or many of my Facebook friends may not frequently update their status messages, but I only see (and thus have most available to mind) the most recent. This is social influence through enabling and encouraging biased social comparison with — in a sense — an imagined group of peers modeled on those with the most recent performances of the target behavior (i.e., updating status).
Influencing the content of updates. In his original post, Enrique mentions how Facebook ensures that users have the ability to update their status by giving them a question that they can answer. Similarly, this box also gives users examples from their peers to draw on.
Of course, this can all run up against trouble. If I have few Facebook friends, none of them update their status much, or those who do update their status are not well liked by me, this comparison may fail to achieve increased updates.
Consider this interface in comparison to one that either
- showed recent status updates by your closest Facebook friends, or
- showed recent status updates and the associated average period for updates of your Facebook friends that most frequently update their status.
[Update: While the screenshot above is from the “new version” of Facebook, since I captured it they have apparently removed other people’s updates from this box on the home page, as Sasha pointed out in the comments. I’m not sure why they would do this, but here are couple ideas:
- make lower items in this sidebar (right column) more visable on the home page — including the ad there
- emphasize the filter buttons at the top of the news feed (left column) as the means to seeing status updates.
Given the analysis in the original post, we can consider whether this change is worth it: does this decrease status updates? I wonder if Facebook did a A-B test of this: my money would be on this significantly reducing status updates from the home page, especially from users with friends who do update their status.]
Texting 4 Health conference in review
As I blogged already, I attended and spoke at the first Texting 4 Health conference at Stanford University last week. You can see my presentation slides at SlideShare here, and the program, with links to the slides for most speakers is here.
The conference was very interesting, and there was quite the mix of participants — both speakers and others. There were medical school faculty, business people, people from NGOs and foundations, technologists, representatives of government agencies and centers, futurists, and social scientists. Everyone had something to learn — I know I did. This also made it somewhat difficult as a speaker because it is hard to know how best to reach, inform, and hold the interest of such a diverse audience: what is common ground with some is entirely new territory with others.
I think my favorite session was “Changing Health Behavior via SMS”. The methods used by the panelists to evaluate their interventions were both interesting to reflect on and good tools for persuading me of the importance and effectiveness of their work. One of my reflections was about what factors to vary in doing experiments on health interventions: there is (reasonable) focus on having a no-SMS control condition, and there are very few studies with manipulations of dimensions more fine-grained. Of course, the field is young and I understand how important true controls are in medical domains, but I think that real progress in understanding mobile messaging and designing effective interventions will require looking at more subtle and theoretically valuable manipulations.
You can see other posts about the conference here and here. And the conference Web site is also starting a blog to watch in the future.
Texting 4 Health
On February 29th I’m speaking at Texting 4 Health, a conference at Stanford University about using mobile messaging for health interventions and research. I’ll be talking about mobile messaging research methods I’ve used to study mobile persuasive technology. Like Mobile Persuasion 2007, it will feature a fast-paced, single-track program with time to meet and talk with participants from health, technology, policy, and research communities.
