Chris Speed’s PhD thesis seems very relevant for people interested in architecture and digital technologies, and more specifically the notion of “social navigation“:

“Through a literature review of the introduction and development of digital technologies to architectural practice, the thesis identifies the inappropriate persistence of a number of overarching concepts informing architectural practice. In a review of the emergence and growth of ‘human geography’ it elaborates on the concept of the social production of space, which it relates to an analysis of emerging social navigation technologies. In so doing the thesis prepares the way for an integration of socially aware architecture with the opportunities offered by social computing.“

As the author describes in his conclusion, the thesis:

“…adressed the research question by analysing how digital architecture had positioned itself without a social agenda through its adoption of a split model for time and space. It went on to discuss the way in which human geography, through an identification of social agency in the production of space, has demonstrated how a combined approach supports many new models for understanding experience. It introduced social navigation as a contemporary form of social computing that offers the methodological techniques for supporting the construction of digital architecture. The author’s own art and design practice was reflected upon, as it was through this that a methodology was developed and applied to the large-scale design project, and evaluated through a substantial ethnographic study.
“

What’s interesting in his work is the different projects he designed to illustrate his theoretical claims. One my favorite is certainly the Random Lift button that I already mentioned here.

Why do I blog this? I only had a glance to the whole thing because there’s a lot of material in there but it looks like an impressive attempts to put together different theoretical bodies and design projects in a very coherent and relevant way to address the relationship between digital and physical space.

Where the first picture only requires to gently caress the button, the second is strikingly more aggressive and requires the presence of an RFID tag to open up the access. In the first case, the symbol depicted is the hand, the situation is more complex in the second one with this non-universal pictogram. Besides, there is also this very non-user-centered number on a white sticker that reveals a different interaction “flavor”. Finally, the concrete wall also reveals the different context definitely more oriented towards car drivers who want to enter a parking lot.

URBAN TRACES - TELEPHONE is a project I recently stumbled acrosss, which examines public phones in different countries. Alina Tudor & Răzvan Neagoe sees public phones as a interesting sign of daily urban life that reveal the relationship between certain cultures and public space:

“We start up from the idea that the identity cannot be anything else but the object of a horizontal analysis and can’t be simply defined as an urban artefact. It represents a cultural sign as long as the virulent changes affecting all the social structures register as a natural answer a form of resistance over the all these mutations.

TEL. continues the series of unconventional spaces as part of the Urban Traces project. Following the interactive “Up in the flat there’s a house” and “Courier” projects, this one brings in front a small but… sizeable space, which is ignored. We have chosen the public phone because it is getting sick of daily urban life syndrome. It has become a place for passers by to have rest, a shelter to hide from the rain… it is vandalised and almost none of the phone booths has the door. This project is a warning sign regarding the collective indifference that is representative for big cities.“

An example from this project:

This project is also part of a “Bank of images”, that is to say a collection of public telephones from different countries and regions of the world:

“The Bank of images project has the intention to collect a series of photographs of public phones searching to offer them a new identity. Images that are representing different telephones and phone booths used accordingly to any other destination besides their primary one, but also the public phones which are placed in different contexts and thus acquiring a double sense in relation to that place are expected.“

Why do I blog this? Public telephone (with or without phones) is definitely a urban signal I am always looking at when visiting a city. A topic we covered in Sliding Friction as well. What I find intriguing in that project is the idea of thinking how they can reveal the state of public space cultures in modern societies. Other public services can also be relevant to observe, such as public toilets, benches or traffic lights.

A recurring topic here, as seen in Zürich yesterday: what it takes to support urban computing: infrastructures and configuration issues.

(via), City Distance is a neat project by bestirario that aims at measuring informational distance between cities. What this means is simple: it creates a visual representation of the the world comparing real geographical distances with informational distances as defined by Google:

“This tridimensional scheme represents the strength of relations between cities from searches on google. The main idea is to compare the number of pages on internet [sic] where the two cities appear one close to the other, with the number of pages they appear isolated. This position indicates some kind of intensity of relation between the cities. After measuring this “google proximity” we divide it by its geographical distance. By this process we obtain an indicator about the strength of the relation in spite of the real distance, a kind of informational distance between cities.“

Which is what the authors of this project calls the “google platonic distance between cities” (See the website for more information about how to compute this).

Why do I blog this? A very curious and insightful representation comes out from this sort of viz. I guess the granularity can be different and reveal finer-grained patterns at smaller levels. Yet another interesting type of urban visualization.

In “The Cybercities Reader (Urban Reader)” (Steve Graham), there is a wonderful text by Anne Beamish called “The City in Cyberspace” which tackles the city metaphor in “virtual worlds” and how superficial the metaphor is often taken.

Some excerpts I found relevant to my interests:

“What do these digital worlds [Alphaworld represented above, Planet9, Le Deuxieme Monde, Virtual Los Angeles] tell us about the creators’ image of the city? When digital urban environments are designed, the downtown is often seen as the Holy Grailv - the vivid, exciting, teasing, tantalizing city is held up within sight, but out of reach. The image of the city is used to attract us and to draw us into the world, but it functions mainly as a decoration or marketing technique intended to get the customer in the door. The creators of these virtual worlds appear to take the image of the city literally but superficially, and they generally do not seem to have given much thought to what it is about a city that their visitors would find appealing. They use the image of the city liberally but strip it of meaning.
(…)
Too often, rather than mimicking the vitality and excitement of downtown, the digital environment is disconcertingly desolate and empty; the buildings are blandly modern; and it is common to travel around these worlds without meeting another soul.

To be fair, though, the crude and simplistic environment is not always a reflection of the creator’s aesthetic taste; it is also a reflection and result of technology, economics and regulation.“

Why do I blog this Working on both fields of video games and urban computing, I find interesting to observe the relationship between the image of the city and its physical counterpart. For that matter, it seems that some progress are attempted especially with games such as GTA IV. The representation of the city in entertainment is surely interesting as a sort of artifacts to depict “possible futures” which are of course very culturally-situated.

Having the Euro soccer cup in Switzerland (and Austria) is interesting as lots of people are cruising around on the streets. Hence, lots of interesting practices or signs of people’s practices occurs. Some excerpts from the last few days:

Paper notes at a street corner to give friends an update about the new whereabouts (it says “We’re at café pessoa, 30 meters ahead in Dassier [street]”:

The hospitality of some places however reach certain limits, as “tents are not umbrella” sign attest from the need to buy an umbrella when it rains instead of staying around:

The inherent contradictions of signs in a city not very well-accustomed to helps its tourists (Geneva):

BUT, a fruitful attempt to help soccer-fans takes the form of a pavement map; nicely employed in the picture below. The elegant map-on-the-ground solution is efficient for people who walk and ride bike, as it gives information in context and also allows congregation around the signs to find the stadium:

And, of course, when it comes to computer-based real-time street information, failure and glitches are never very far:

The presence of other cultures, and their intricate relationships with their host country. In this case it’s Spain and Switzerland: some only put their spanish flag but most of the flag we see are grouped with both a swiss and spanish flag (you can replace Spain with Portugal, Italy, Turkey and France in the sentence before):

Why do I blog this? what a nice context to observe cultural issues and whatever can be related to human behavior regarding mobility and techniques/technologies/organizational solutions for recurring problems.

The recent story of Google cars causing stir in Rome still makes me wondering about the perception of so-called “urban computing” and citizens. To put it shortly, the problem was basic: Google recently brought in black cars in Rome that take pictures for the Google Streetview project (yes at some point you have to physical artifacts taking PICTURES of streetviews, it’s not just virtual). BernhardWarner for the timesonline hence reports the following people’s reaction to these black cars:

“On cue, pedestrians shuffled off the street and into bars, out of sight of the offending vehicle, no doubt wondering if these are the new intrusions that must be endured after a sudden shift to the right. Your correspondent managed to snake through a queue of cars at a traffic light to get a better look at the vehicle that upset so many mid-afternoon espressos.
(…)
Just then the Google car swung left and I followed, in a very slow pursuit. The identical scene unfolded before me: Romans stumbling into shops and bars, hoping to be out of view of the camera’s lens“

In a sense, they perceived it as “a new type of video surveillance vehicle”. I won’t enter into the details of the explanation provided by the timesonline (the election of a right-wing mayor… who wants to promote tough-on-crime platforms) but this situation seems certainly revealing of a troublesome relationship between technological assemblage.

The picture of the google cars in the Netherlands made by Lars van de Goor shows how the whole pack can be intimidating:

Why do I blog this? what I find interesting here is less the perception of a service (that can be articulated as “urban computing”) but instead the sort of experience of the infrastructure needed to provide a service. A flock of all-similar black cars wandering around the city with huge camera-devices may indeed by an intriguing experience as it may came out from the blue. Will we see more of this sort of encounters in the city of the near future?

Btw, Mauro were in you in Rome? have you seen this?

When Fabien and I had to find a title for our photo booklet “Sliding Friction: The Harmonious Jungle of Contemporary Cities“, the notion of “friction” came up very easily in the conversation. Having read few books by Lefebvre in the last few years, it was certainly one of the reason for picking up that term. Digging my “Docs” folder on my laptop, I recently unburied a very good paper by Jensen & Lenskjold
about similar issues. It’s called “Designing for social friction: Exploring ubiquitous computing as means of cultural interventions in urban space“.

Here’s how they define this “social friction” (a notion they discuss using Lefebvre and De Certeau):

“Social friction is a fundamental aspect of everyday life. We use the term to denote the process, which separates different expressive behaviours and contexts from each other. Social friction is at play when people in the city act and express themselves in surprising and unconventional ways. When people challenge existing norms and leave marks and traces on their social and physical surroundings.
(…)
Social friction can also be described as the ‘rubbing of’ of people on each other. It is the kind of friction that occurs when people, who hold different backgrounds, understandings and experiences, meet on the bus or in the street and exchange opinions, stories or maybe just gestures and glances.“

Now, what about “social friction” and ubiquitous/urban computing? The authors’ point is that this notion is helpful “in the development and analysis of ubiquitous computing in relation to art and design“. They articulate social friction a critical position, which could be applied as a strategy for design. Relying (or designing for) social friction is then seen as way to release new forms of social and cultural potentials. Which, is also related to Nicolas Bourriaud’s idea of “art as a social interestice”.
Why do I blog this? my interest in urban computing and art practices led me to that paper, I quite like that notion of “social friction”. Let’s sleep on it.

If there’s a population that is often overlooked (or dismissed) by urban designers or urban technology engineers, it’s definitely the homeless. A CHI 2008 paper by Le Dantec and Edwards entitled “Designs on Dignity: Perceptions of Technology Among the Homeless” deals with this topic, trying to understand how technology — from cell phones to bus passes—affects their daily lives. Such a qualitative study allows them to challenge reseachers’ assumptions about people’s relationship with technology and discuss possible opportunities to develop services.

Using Photo-Elicitation Interview, the researchers identified different unique needs homeless had and characterized perceptions of technology among them. Some excerpts from the results:

“Staying Connected: The first theme was the importance of staying connected to family members and friends during spells of homelessness. (…) Many of the participants came from places other than their current urban home and keeping in touch over distance was something they worried about.

Synchronous v. Asynchronous Connections All of the participants had voice-mail accounts through local organizations. These accounts were meant to provide a stable number of contact and aid in job searches and managing appointments or other personal business. (…) The difficulty for a number of participants was in accessing their voicemail, leading to a decidedly asynchronous style of communication when using the telephone.

Mobile Telephony The preferred way to maintain a stable connection to family and friends for many of the participants in the study was through a cell phone. (…) cell phones were not without problems (…) the ongoing cost, the need for access to power to recharge the phones, and the inevitability of theft when living in and out of shelters.of his extended friends he would tell about being homeless.

Identity Management: For participants in our study, different forms of identity management came out through their use of technology and social institutions. (…) Identity management took both technology- and non-technology-focused forms. For example, on the non-technologic side, identity management appeared in how participants
managed their physical appearance

Access to Information, Social Networks: The social network was the primary mechanism participants in this study used to navigate the world around them.

The Digital Divide: Participants varied widely in the use of information technology, effectively resulting in an internal “digital divide” within the homeless community.

Health and Medication

Getting Around: Moving around the city was an imperative for our participants.“

As the authors say, although these needs can suggest opportunities for designed solutions, they find it more relevant to consider the broader implications for urban computing:

The social dynamics that are playfully exposed through urban computing ideas could be more thoughtfully considered in their relation to the less-priviledged participants of the urban environment. Appropriate technologies need to consider more than the usability or psychological appropriateness of an interaction. We need to put careful thought into the social impact technologies have for non-users as well as users. In using technology to redefine boundaries, we have an opportunity to do so inclusively, bringing the periphery into sharper focuses, inviting in the disenfranchised and the under-served. “

Why do I blog this? This kind of research help to figure out alternative vision of current urban computing ideas as it allows to adopt another lens concerning people’s relationship with technology and the city. All the issues described in the paper are extremely important to consider the situation in a more holistic way (and certainly not only as a quest for ” design opportunities”).

In addition, I also find interesting the way some concrete problems are considered here. For instance, the article describes how some homeless people make communication decisions based on their ability to predict cost using pre-paid cellular service. The problem of these phones is that purchased minutes expire after as little as 30 days and phone numbers that become inactive can be reclaimed by the service providers after 90 days (which is difficult for people with irregular incomes). What is interesting here is the notion that the problem is not necessarily about the technology itself but rather the whole model of its deployment (business model). This is a good example of a technosocial situation in which the whole ecosystem should be taken into account if a technology is to be adopted. Of course, in this case, this kind of limit in pre-paid phone contracts is generally aimed at getting rid of this sort of population…

Encountered yesterday on my way to a meeting, this nice street camera has been protected but some people have found a more interesting side-effect of the protection. The accumulation of bottles might, down the road, influence what the camera is watching.

Finally managed to read the oversized Paris ville invisible book by Bruno Latour and Emilie Hermant (1998). The whole thing is an amazing photographic essay on the “social” and technical aspects of the city of Paris (”social” in Latour’s sense). It’s a bit like Susan Star’s article called The Ethnography of Infrastructure but definitely in Latour’s words (and yes it’s definitely french). There is also a web version, defined as “a sociological web opera”.

For this post, I am mostly concerned by the notion of traces, their visibility and their implications. An important part of the book is about various “channels of signifiers”: from collected data like temperature or time to their computation by intermediaries (sensors, computers) and the map and model outputs employed by institutions such as telecom operators or police departments

Some excerpts from an english translation by Liz Carey-Libbrecht:

“Megalomaniacs confuse the map and the territory and think they can dominate all of Paris just because they do, indeed, have all of Paris before their eyes. Paranoiacs confuse the territory and the map and think they are dominated, observed, watched, just because a blind person absent-mindedly looks at some obscure signs in a four-by-eight metre room in a secret place. Both take the cascade of transformations for information, and twice they miss that which is gained and that which is lost in the jump from trace to trace – the former on the way down, the latter on the way up. Rather imagine two triangles, one fitted into the other: the base of the first, very large, gets smaller as one moves up to the acute angle at the top: that’s the loss; the second one, upside down in the first, gets progressively bigger from the point to the base: that’s the gain. If we want to represent the social, we have to get used to replacing all the double-click information transfers by cascades of transformations. To be sure, we’ll lose the perverted thrill of the megalomaniacs and the paranoiacs, but the gain will be worth the loss.
(…)
The more information spreads and the more we can track our attachments to others, since everywhere cables, forms, plugs, sensors, exchangers, translators, bridges, packets, modems, platforms and compilers become visible and expensive – with the price tag still attached to them. the reader will perhaps forgive us for our myopic obsession with the trails of traces“

About how to reveal the invisible and the role of this book:

“the visible is never in an isolated image or in something outside of images, but in the montage of images, a transformation of images, a cross-cutting view, a progression, a formatting, a networking.
(…)
In photos and text we’ve attempted to highlight the role of the countless intermediaries who participate in the coexistence of millions of Parisians. In the series of transformations that we followed with myopic obsession, we would have liked to have kept each step, each notch, each stage, so that the final result could never abolish, absorb or replace the series of humble mediators that alone give it its meaning and scope. “

Why do I blog this? The book is a very intriguing read for anyone interested in contemporary cities and their underlying activities/infrastructures. If you liked Italo Calvino’s “invisible cities”, that book written by Latour (with pictures from Emilie Hermant) is a must read. The notion of traces described here is very Latour-ian to some extent and it’s interesting how he uses it to describe what happens in a contemporary city such as Paris. What I find relevant here is this idea of “intermediaries” and the observation of the transformation he discusses.

If you’ve read Dan Hill’s post “The Street as a Platform”, that book is a theoretical exploration of the issue of technologies in city space. There is of course much more to draw from this book, which I will explore in following blogposts.

Pneumatic tubes and networks (as the one described in Boris Vian’s novels) have always fascinated me. The name itself is gorgeous and it really looks like a strange vehicle. Although there are sometimes still use to transport cash and documents (transparent supermarkets pneumatics are intriguing), their usage has often stop or led to new possibilities: using tubes to put optic fibers to serve as internet infrastructure OR use both technology and pneumatic to vehicle paper documents which still matters in the 21st century.

Also of interest is the mapping of pneumatic networks, see for instance the Paris network as shown in this article:

Why do I blog this? What is interesting here is not that you can get web-based remote control of an electro-pneumatic (nor the impact on net neutrality) but rather the existence and sometimes the resilience of this communication network. An old version of the “city of flow” sort-of.

The other day I mentioned this short article I wrote in JCDecaux trend report. It was about how skateboarders “read” space, make decision about where they do skateboard or to hang out with peers. In a sense, it’s about “social navigation” and what sort of “footprints in the snow” matter for skateboarders. I dug up some examples from my city ventures below.

Choosing a skateboard spot according to the physical aspect of the place

For instance, in Niteroi (Brasil), that curved sidewalk is definitely an invitation to skate it:

This bench in Zürich (Switzerland) is also an obvious point of interest (from the physical point of view) but the presence of wax also attests that OTHERS are using it as a spot. The place can also be more than a physical spot as the presence of wax indicates it marking by a community. It reveals the appropriation by a click of skateboarders (and the likelihood to find them here on saturday afternoon)

Skatespot approval or how places are validated for certain activities

This “thumb-up” stickers found in front the of the University of Geneva indicates the approval of the spot by a community of skater (in that case a local shop/community):

Skateboard map

The usual paper map, for example in Lyon (France) found in a shop called Wallstreet, that depicts interesting spots to do skateboarding:

And of course, there is an on-line/participatory version, named freeyourspot, see the example of London (which not really reveal about skateboarding potential there):

Why do I blog this? of course one could use lots of other examples but I find skateboarders a very interesting target group to study spatial behavior, and how they use various techniques (from wax to participatory websites or cell phones). In this post, I tried to update some examples of how skateboarders read/navigate in space.

I find them really interesting examples IMHO of what some would refer to as “situated technologies”.

A location-based annotation that indicates when water overflowed that street in paris. Interesting marker of the past (from 1910) that aims at reminding a different state of the environment. That’s the sort of Holy Grail for mobile phone service developers… who try to promote a digital equivalent to this. Where are we in 2008 wrt to this sort of system?
