From Kodak to the Mobile Phone: Urban Data and the Scientific Life | August 17, 2010

Mobile Power

This is a repost from the Polis blog with my comments (my comments first, polis blog From Kodak to the Mobile Phone below):

Thank you for this post. I think that the mobile generation with their ever more powerful mobile technologies are changing how we view, analyze and plan our cities. I work with youth in East Africa, and i have found that through the use of mobile phones, which are now prolific throughout the region, we have been able to not only capture images, both still and in video, but use these images to tell the rarely heard story of some of the poorest of the poor. (An example of such a project is

I have as well found that “photovoice” is an excellent way to allow people to “map” their communities. I have used this technique with youth in North America, through the Growing up in Cities project , and more recently through work with UN-HABITAT on their community mapping project (you can check out a story a wrote for them titled Bridging the Digital Divide .

What is exciting is the integration of photos with other technologies – specifically mapping. Initially we saw this integration with google earth – where one could geo-locate photos or video. This has gone to the next step with new platforms such as Usahidi where we see events being mapped through tweets from mobile phones, and combined with photos and other digital imagery. A good example of this is the Map Kibera project.

There is no doubt that this new approach to analyzing and planning our communities is exciting. Equally exciting is the fact that it gives communities the power to do this in realtime.


From Kodak to the Mobile Phone: Urban Data and the Scientific Life

We appear to be living in a renaissance of data — large datasets, to be more precise — as the new purveyors of insight into the social, economic, and political lives of cities. Portable devices such as GPS and mobile phones which we carry with us passively emit signals as we go about our day, and these signals in aggregate ultimately map the ebbs and flows of urban life (as evidenced by much of the work from MIT’s SENSEable City Lab. One such example runs along the lines of a time-lapse, geographically oriented visualization of text message density across a particular set of cities). The trends and conclusions from all this data can, at best, spur local governments to reshape urban strategies — be it for traffic and crowd congestion control, public transportation policies, or even understanding the potential transmission paths of local epidemics.

In the age of aggregate datasets, I cannot help but recall the concept of the “photovoice”: a method of data collection through systematic photography and the use of images as evidence. The output from a photovoice approach yields data, certainly, but it is data that is often richer and more nuanced with its ethnographic content — data which is arguably not as immediately straightforward and processable as mobile phone signals.

When the Kodak — the first simple camera — was invented, George Eastman articulated his vision in The Kodak Primer:

“[…] We furnish anybody, man, woman or child, who has sufficient intelligence to point a box straight and press a button, with an instrument which altogether removes from the practice of photography the necessity for exceptional facilities, or, in fact, any special knowledge of the art.”

The proliferation of cameras 122 years later on mobile phones further dismantles the barriers to practising photography, but while we may be somewhat liberated from the shackles of a specialized artform, the ultra-accessibility of the camera beckons us to approach life — or more specifically, documenting life — in a more deliberate, scientific way. This could conceivably mean having photo albums not just of smiling babies and family members, but of public toilets and recycling amenities in our neighborhood, or of homelessness on our streets. In doing so, we’d be generating a meaningful corpus of photographic data about our urban environments in their painstaking logistics and heart-rending problems, and hopefully contributing to our collective well-being from the actions that issue directly from this data.

The idea of being more scientific in our approach to life and documenting life with tools like the ubiquitous camera has been suggested by researchers like Dr. Deborah Estrin at UCLA’s Center for Embedded Network Sensing, and deserves some thought. Coupled with geolocation technologies and other metadata, the proliferation of photos on online social networks and photo albums today would paint a compelling snapshot of our urban livelihoods and provide more texture and grist to the binary datasets of bits and bytes that we passively generate on a daily basis.
