Unlocking Digital Cities

The November issue of Wired Magazine (UK) features "Unlocking the Digital City", a series of articles exploring how new technologies have transformed - and are continually reinventing - urban life and urban landscapes. The entire issue is worth reading. Below are excerpts from three perspectives on the promises and realities of the digital age in urban environments. (This blog post has been cross-posted on the OAC. Discuss it here).

'Sense-able' urban design
Scholars back in 1995 speculated about the impact of the ongoing digital revolution on the viability of cities. Only 14 years ago, the mainstream view was that, as digital media and the internet had killed distance, they would also kill cities. Technology writer George Gilder proclaimed that "cities are leftover baggage from the industrial era" and concluded that "we are headed for the death of cities", due to the continued growth of personal computing, telecommunications and distributed production. At the same time, MIT Media Lab's Nicholas Negroponte wrote in Being Digital that "the post-information age will remove the limitations of geography. Digital living will include less and less dependence upon being in a specific place at a specific time, and the transmission of place itself will start to become possible."

In fact, cities have never prospered as much as they have over the past couple of decades. China is currently building more urban fabric than has ever been built by humanity. And a particularly noteworthy moment occurred last year: for the first time in history more than half the world's population - 3.3 billion people - lived in urban areas.

The digital revolution did not end up killing our cities, but neither did it leave them unaffected. A layer of networked digital elements has blanketed our environment, blending bits and atoms together in a seamless way. Sensors, cameras and microcontrollers are used ever more extensively to manage city infrastructure, optimise transportation, monitor the environment and run security applications. Advances in microelectronics now make it possible to spread "smart dust" networks of tiny, wireless, microelectromechanical system (MEMS) sensors, robots or devices. [Read more ...]

Words on the Street
Over the last decade a great number of people on Earth have embraced the digital mediation of everyday life. Without considering the matter with any particular care, as individuals or societies, we have installed devices in our clothing, our buildings, our vehicles and our tools which register, collect and transmit extraordinary volumes of data, and which share this data with the global network in real time.

Under such circumstances, it is only natural that a great many of these systems will be used in the planning and management of cities. In the interest of managing traffic and, ostensibly, enhancing public safety, our streets are ringed with networked cameras, salted with embedded sensor grids. We traverse urban space in networked vehicles that are GPS-tracked and leased to us as hourly services like Vélib' and Bicing and City CarShare, or tap our way on to mass transit with RFID-enabled payment cards like London's Oyster.

Your Neighborhood is Now Facebook Live
... Miriam "went to the Flea" (the flea market, I presumed). Out on the street a few minutes later, Eva herself appeared, violin case slung over her shoulder. It wasn't until we bumped into Miriam a few blocks later, bags full of second-hand trinkets, that it hit me: my Brooklyn neighbourhood had become Facebook Live.

Conventional wisdom says that technology is bad for real-world communities, that we are often alone at home in front of blue screens. This is no doubt true. But we are also out on the street stealing glances at smaller screens, and interacting in more meaningful ways because of it. When it comes to technology and cities, today's thrilling development - "thrilling", that is, if you like real cities and corporeal people - is that social networking is enhancing urban places. I may have been only affirming face-to-face the interactions I just had in cyberspace, but that act was significant for the future of our cities.

The bandwidth of urban experience has increased. The ancient ways are still there: the way a place looks, the neighbours we wave at and the hands we shake. But now, there is an electronic conversation overlaid on top of all that: tweets and status updates, neighbourhood online message boards, detailed mobile electronic maps, and nascent applications that broadcast your location to your friends. This is far more interesting than what we were promised a decade ago: the proverbial coupon blinking on your mobile as you walk past Starbucks. (I have yet to experience this.) [Read more ...]

Anthropology Blogs

I came across this list of the top 25 anthropology blogs as compiled by Invesp Consulting (an e-commerce conversion optimization company, of course). Their Blog-Rank statistics are based solely on (automated) data extraction from various aspects of online content, such as RSS membership, Yahoo and Google indexed pages and pagerank, visitor and pagehit counts, link-to-page ratios, Alexa and Technorati ranking and social sites popularity (Digg, Stumbleupon, Delicious, Redditt, Propeller and mixx). It's an interesting way to see how the the marketing world's ranking tools apply to mostly academic blogs, with a healthy mix of social web for good measure.

At the top of the list are favorites like Afarensis, Conversations with Dina, Material World and remote central. There are plenty more anthro blogs out there, too. See my blogroll in the left column of this page for some of my favorites or the sites below:

All Top: Anthropology
The Daily Reviewer
Academic Blogs
Antropologi.info Feeds
Online Universities Top 100 Anthropology Blogs
Neuroanthropology: Anthropology blogs, networking and online community resources

Edit: Here's another new online content ranking tool worth exploring.

PostRank is a scoring system developed by AideRSS to rank any kind of online content, such as RSS feed items, blog posts, articles, or news stories. PostRank is based on social engagement, which refers to how interesting or relevant people have found an item or category to be. Examples of engagement include writing a blog post in response to someone else, bookmarking an article, leaving a comment on a blog, or clicking a link to read a news item. PostRank scoring is based on analysis of the "5 Cs" of engagement: creating, critiquing, chatting, collecting, and clicking. By collecting interaction engagement_metrics in these categories the overall engagement score is calculated and the PostRank value is determined.
Check out PostRank's anthropology pages, which present yet another perspective on the anthro blogosphere and popular feeds. Its dynamic "engagement metrics" show changes in content "popularity" over time, and you can view the most recent blog posts and anthropology-tagged news and delicious bookmarks in a single stream of content.

VoiceThread for collaborative learning and teaching

I read this review article today on Educ@conTIC (Spanish only) about a web-based service for creating collaborative, multimedia conversations. VoiceThread is "a powerful new way to talk about and share your images, documents, and videos".

With VoiceThread, group conversations are collected and shared in one place from anywhere in the world. All with no software to install.

A VoiceThread is a collaborative, multimedia slide show that holds images, documents, and videos and allows people to navigate pages and leave comments in 5 ways - using voice (with a mic or telephone), text, audio file, or video (via a webcam). Share a VoiceThread with friends, students, and colleagues for them to record comments too.

Users can doodle while commenting, use multiple identities, and pick which comments are shown through moderation. VoiceThreads can even be embedded to show and receive comments on other websites and exported to MP3 players or DVDs to play as archival movies.

Aimed at all levels of learning and types of educational environments, it was ranked 18 in the recently published Top 100 Tools for Learning 2009 ahead of Gmail, Wikipedia, Diigo, Keynote, Dropbox and Scribd.

I've had a brief look around the site and it is fairly easy to navigate as well as surprisingly fast in loading the page elements (@2.5MB/sec, WinXP, Firefox 3).

The steps for getting a VoiceThread up and running are straightforward: Simply sign up/register, click on "create" and upload the image, document or multimedia you wish to include in the interactive slideshow, repeating the process for as many slides as you like. It also supports importing content from Facebook and Flickr. Once the slideshow has been created, selecting "Publishing Options" will provide a number of ways to customize accessibility (private, public, invitation only) and comment moderation. Once you save the changes, a unique URL is generated so you that can share and/or embed the final product. There is no software to install and all the editing and viewing take place directly in the browser window.

After some minutes of examination, I'm not overwhelmed by the diversity of publicly available slideshows, but once comments have been added and interactivity becomes evident, the benefits of VoiceThread are much clearer. Its main potential is for creating streamlined, easy-to-view, shareable, interactive pages to evaluate or compare specific documents, texts, images or videos. What makes VoiceThread interesting are the ways in which users can interact with the media. Comments can be added by voice (microphone or telephone), text, webcam or MP3/WAV file upload. New comments are automatically stacked around the sides of the main slideshow item, displaying user icons which viewers can click on to hear/read the comments. It is also possible to doodle on the displayed image while recording the comment to illustrate specific points or thought processes. (Phone-in comments are restricted to domestic US origination only, rendering them useless in Europe at the moment). In essence, the comment functions combine typical slideshows and text input with doodle/tagging (as on Flickr, whiteboard), video response (as on YouTube) and voice recording.

The slight catch is that there are limits to free accounts, so although each VoiceThread can host up to 50 slides, you are only allowed 3 VoiceTreads per account. There are also time limits to comments, only 75MB file storage and a measly 25MB file size limit. Archiving, audio comments, creating and managing groups are all restricted to paid Pro accounts, as well as the facility to export a VoiceThread and all its related media (comments, doodles, etc) for playing and storing offline or on external displays, TVs, DVD players, phones, etc. VoiceThread Pro accounts include 30 exports as part of the package. More on pricing and comparisons here and here for Higher Education accounts.

Probably the two most significant ways I can see using this tool in learning and teaching are by allowing students to create their own interactive presentations aimed at an academic community of their teachers and peers, and for hosting e-seminars, book/article reviews or analyses where the comments can be archived to supplement other full-text websites or transcripts of events. Of course, the slideshows can also be embedded on other pages, such as personal blogs or, for instance, the OAC. There are a few anthropology-related VoiceThreads publicly available on the site, but all with limited audio and few comments, leaving plenty of room to host more content in this field.

My interest in VoiceThread largely comes from the potential for improving learning/teaching in terms of interactive class assignments and "social learning". Here are two of the best examples I've seen on the site so far: Teachers discussing Web 2.0 and "What does the network mean to you?"

Have experience using VoiceThread? How does it compare to other online collaboration services?
