Locative Media

Experimental Ethnography with Urban Tapestries

A nice paper about the Urban Tapestries project: Urban Tapestries: Experimental Ethnography, Technological Identities and Place, an LSE Electronic Working Paper by Roger Silverstone and Zoetanya Sujon.

Urban Tapestries provides a mobile location-based platform to connect people with the places they inhabit through their stories, experiences and observations. Currently based on an 802.11b mesh network in the heart of London, ordinary people author their stories of the city and embed them in the places that inspire them. Others who are logged into the system can read these stories, author their own and engage the largely invisible, multidimensional layers accumulating in the city. Our research asks if people use UT in meaningful and interesting ways. Drawing from theories of everyday life and urban space, we have developed experimental ethnography as a method for investigating the relationships between communication technologies, users and the socio-geographic territories around them. Respondents are asked to play with an early Urban Tapestries prototype and this research explores what they do, their technological identities, their relationship to place and the meanings they generate. Urban Tapestries facilitates the negotiation of boundaries and we found that it does augment notions of connectivity – to place and to those within that place. However, our research revealed that some do not interpret this connectivity positively.

Why do I blog this? I find interesting to have a usage analysis of a specific locative media. The study if very relevant (I appreciated the fact that they took into account the level of technological comfort which is very important if you want to deploy this kind of tech at a large level). The content analysis of the 'pockets' is nice as well:

  • Recommendations (good or bad)
  • Personal experiences (I was here, I did this, this reminds me of)
  • Information (this place is)
  • Speculations (questions, fiction, maybes and whatifs)
  • History
  • Observations and Descriptions

Perhaps the most interesting part is the conclusion in which they extract the most significant results (I quote):

What we have found and suggested during the course of the study are a number of dimensions of this problematic of socio-technical change, dimensions which are particular to the affordances offered by UT.

  1. The first is the question of the contradictory and unstable relations that individuals have with their technologies. Everyday life is, albeit variably as our respondents have illustrated, dependent on a range of increasingly portable technologies that are both enabling and disabling of social interaction; that are both liberating and constraining.
  2. The second is the issue of identity. Marshall McLuhan famously described media technologies as extensions of ourselves. (...) Our research suggests how important such a notion is, and in what ways these extensions are, or can become, crucial parts of our identities, as projections of the self, as well as props and supports in our struggle to sustain ourselves as viable social beings. (...) But understanding technology as a constituent of identity is key if we are to further an understanding of how such technologies as UT could develop, or indeed how indeed one might develop UT in the future.
  3. Mobile telephony is both an extension of self and an intrusion. UT technology likewise. Its essential double-edge will need to be managed if it is to have a value in the enhancement of social life.
  4. a number of them [users -n] talked about UT as, possibly, an opportunity for play. And the idea of playing in and with the city appears, at least to some, attractive. (...) UT was seen as toy-like, and as such possibly marginal to the real issues of the everyday. [indeed, see anne galloway's work]
  5. This leads to the final issue. The issue of place. UT is a technology that engages directly with space and place. It offers a way of fixing location, a kind of marking of the city with meaning. (..) UT is a way of marking that significance both for the individual and, in principal, for the collectivity – both the ad hoc collectivity of passing tourists and the more grounded collectivity of neighbourhood and community. [here see timo arnall's work]

I also liek the conclusion "The research reported here, then, suggests that technologies are never less than social. They emerge from social action, and they continue to be dependent on social action if they are to have any meaning or usefulness.". That is definitely the point here with today's technology. Such technologies will work only if a critical mass of people use it, the real power will emerge from this.

On a different note, I am stilll waiting locative media studies much more focused on smaller scales group. Like for instance how small groups of people use them to do something jointly. And what would be the socio-cognitive consequences of using such information. Well of course, it's closer to my phd topic ;)

NFC powered presence

Finally a interesting hack using NCF (Near Field Communication which is besides closer to the market reality): Janne Jalkanen developed a NFC powered presence application:

I took two NFC tags (essentially very small memory cards with a radio that can be read/written from up to a few centimetres), wrote the URL of my web service on both of them (using the ServiceDiscovery app included), and wrote a little JSP page that handles the interfacing with my blog.

Then I stuck one tag on my work monitor, and another one at home. Now I can just touch one of these tags with my phone, and a few seconds later (some delays are involved with starting the Java midlet and connecting to GPRS) the little box on the right changes to show my location. Voila: NFC-powered presence.

This is in essence no different from doing a Trackback ping; I'm just doing it by touching something with my phone. Not traversing menus, not using the keyboard, not even glancing the screen.

Koko-memo (Here-it-is)

Koko-memo (Here-it-is) is a a prototype handheld map annotation system that allow users of the system annotate maps close to the location of the users. It's done by Tomoko Imai, Naoki Sakakibara and Chika Sekine (UDIT Ltd.) + Hoshino Takeshi (Design Center, Hitachi Ltd.)

The hardware is a commercially available mobile phone with 2.2 inch liquid crystal display, a camera, and a global positioning system (GPS) receiver to allocate the location of the mobile phone. It weighs 125g and can be controlled with one hand. We developed Koko-memo software for the mobile phone and it allows users to obtain appropriate maps for the usersf location and paste photographs and comments on the maps. Users who are registered to a Koko-memo server can obtain the annotated maps and can add further information to the maps. Firstly, users capture images using the camera of the mobile phone and attach them to e-mails together with comments and location information that are detected by the GPS system. Then, they send the e-mail to the Koko-memo server. The server processes the messages and updates the information on the Koko-memo server. Then the users are able to watch maps with the latest annotations by accessing web pages with the URL of the Koko-memo server. Since each annotation data has a date, users can evaluate reliability of information based on the date information and the server can delete outdated information.

Location-based services and lampposts

An interesting news from this week: a British company plans to roll out high-speed wireless networks and location-based services using street lampposts.

Last Mile Communications says the humble lamppost can be used to provide broadband Internet access and also to store useful information about their location.(...) people who run an application called the MagicBook on a mobile device will be able to connect to their nearest enabled lamppost and access the information stored on it.

Last Mile is also hoping to win backing from emergency services agencies. For example, the precise layout of buildings could be stored on a lamppost and be accessible by firefighters in an emergency. (...) Last Mile cites as a strength its lack of reliance on other telecommunications infrastructure such as local telephone exchanges, which means it could keep working in the event of widespread network failure.

Apart from that other interesting and RELEVANT uses?

About collaborative cartography

(via) New Scientist has a very pertinent article about map hackers (like Jo Walsh who use GPS to build their own maps.

ARMED with a Global Positioning System receiver and a pair of itchy feet, Jo Walsh walks a different route around town each week. She is slowly but steadily building a digital map of her neighbourhood in Bristol, UK. In doing so, Walsh is reinventing the pioneering spirit, for she is one of hundreds of people using cheap, off-the-shelf satellite tracking equipment to make their own maps.

The principle is simple. Set your GPS receiver to record longitude and latitude at frequent intervals during a walk, bike ride or car trip, then download the information to a computer and watch as it traces out your journey on screen. And by combining data from various trips, you'll get a rough but usable digital map of the world you live in. "You just need a GPS receiver and data cable and then anyone can do it," says Walsh's husband and collaborator Schuyler Erle

Let's then quote their book: Map Hacks, a must-read for map hacker wannabees. The collaborative map field appears to be booming, it's funny that there were no talk about it (as well as about locative media) at eTech 2005. Maybe, as Jo said in the Locative mailing list it's because it's now no longer emerging but people begins to really use it! OK so now collaborative cartography is not just a trend, it's used; which is good. I see many interesting domain in which it could be useful, ranging from educational purposes (learning how to map, discovering areas...) to more serious issues (for firefighters and deminers for instance)

Douglas Rushkoff in the Feature also deal with that issue. He underline the very thriving "collaborative map/cartography" community and also claim that the wireless industry is not so much into it.

Although media artists are desperately in love with the possibilities afforded by locative media, sadly, the mobile phone industry outside of Japan and South Korea hasn't exactly warmed to the nascent field. The Mapping Hacks trio's list of demands from operators and manufacturers includes low-cost location lookups, user access (through the phone) to everything that his phone knows and open hardware and software platforms for experimentation and innovation. All of these comprise a fairly reasonable wish list, but considering the conflicting interests of the many links in the mobile value chain, the operative word is still "wish." (...) nd until locative media applications offer wireless providers or phone manufacturers a genuine competitive advantage in the way that, say, driving maps do, a future of collaborative cartography may have to wait until kids raised on GPS crayons are running the world.

A flickr for maps?

Peter Dreyer in Future Now advocates for a flickr-like website for personal maps.

Imagine if we all gave up some of our right to privacy and produced and shared dynamical private maps. Not just maps of the local neighbourhood, but maps containing information about when we had been where. Pretty straightforward. It would no longer be left to Hollywood to speculate in what would have happened, if I had taken another route to the office this morning - or if I had been 10 minutes late. On the map sharing server (Mapr?) some pattern recognition routine would allow me to see, who I would have met in that case. It would even be possible to perform match making among persons travelling in my foot steps but at different times. People I may otherwise never have met would suddenly leave anonymity. As in the movies our lifes would begin to converge.

Some interesting data-mining could indeed be done... but it raises huge privacy issues...

O\'Reilly Where 2.0 Conference

O'Reilly Where 2.0 Conference

O'Reilly Where 2.0 Conference explores the emerging consumer and enterprise ecosystems around location-aware technologies--ecosystems that increasingly impact the way we work and play. Location-determining technologies like GPS, RFID, WLAN, cellular networks and networked sensors enable an ever-growing array of capabilities from local search, mapping, and business analytics to enterprise integration, commercial applications, and software infrastructure.

It seems to be marketing and techno-oriented, focused on the usage of LBS but not really from the HCI point of view. Might be worth anyway to have a glannce at what is discussed there.

And now elephants send SMS

Nice story on engadget

As part of a campaign by NGO Save the Elephants, pachyderms in Kenya are getting in on the action, as well. They’re being fitted with specially designed GSM/GPS collars that hold what are essentially mini cellphones, which are programmed to send SMS messages to farmers’ mobiles with the latest GPS positions of the animals. The elephants can also be tracked on the web in (near) real time via Animal Tracking System software, which gathers data from the GSM/GPS tags and makes it available via standard web browsers. All we gotta say is, we hope those elephants have a good rate plan

What's the next step?

Mapping, GIS and Augmented Reality

A very relevant take about mapping, GIS and Augmented Reality in O'Reilly.net by Tyler Mitchell (via the goewanking mailing list).

I want to see AR applied to my area of interest - mapping. While certainly AR has some strong ties to locational information in general, it could serve a very specific purpose in various industries using Geographic Information Systems (GIS) and mapping. Many of the key data requirements for AR are readily available in GIS data managed by government and industry

Well that's something we discussed this morning in the train with fabien: how the locative/GIS community and the AR people are connected. They do have similar problems to handle but there does not seems so many cross-over. The author advocates for more connections, especially to use of 3D maps in AR applications which is indeed pertinent:

We produce a lot of maps for field crews working in the forest. It would be great if they could have those maps digitally available through AR - projected in front of them. They could find the road turn-off to their work area easier, as it gets drawn as a thick line in their display. They could see the boundaries around their areas without having to hunt for small plastic ribbons tied on trees every few meters. Or, better yet, they could fly over areas in a helicopter and look down seeing their areas outlined in red on the ground. (...) I believe it's time to liberate that data from 2D conventional maps and start getting up front and personal with it in the real world.

The final sentence is ambitious but very true, let's go back to work.

GPS Treasure Game

(via) Play Treasure Hunt is "a location based pervasive game for handheld devices, combining a clue driven Treasure Hunt with an action strategy Mech battle game.". It's based on GPS.

Treasure Hunt is a location based mobile phone game that uses GPS and internet enabled handhelds. We have hidden an imaginary treasure somewhere in your game zone and you must attempt using the clues we give you to try and find it. All players begin the game with one video or picture clue, and a number of multiple-choice answers, only one of which is the correct answer. Be careful when answering the clues, if you answer the clue incorrectly your next clue won’t be so helpful in your quest for the treasure, instead you might find yourself going in circles. (...) To find the treasure you must answer the clues. Use the clues you have received over time to piece together the puzzle, use these clues as a road map to find the location of the treasure. Its not that hard, we want you to win, just try and figure it out.

Blue Force Tracking

An example of locative media used by the US Army: Blue Force Tracking (Force XXI Battle Command, Brigade and Below System (FBCB2).)

Blue-force tracking — technologies that tell U.S. military units where friendly forces are — has come of age in Iraq operations. (...) it gives combat vehicles a dashboard-mounted laptop and a roof-mounted transponder/receiver to beam information via satellite to headquarters and other vehicles. The result is an all-weather, always-on, near-real time picture of the battlefield that answers the questions: Where am I — and where are my friends? This helps coordinate a force’s striking punch and reduce friendly fire. (...) Using lessons learned in Iraq, the Army and industry are working to improve blue-force tracking, adding bandwidth to transmit more data on friendly and enemy units, support three-dimensional imaging, and allow expanded text messaging. In development is a hand-held electronic version of blue-force tracking that will allow dismounted ground forces to maintain situational awareness.

Vindigo LBS

I am skimming a case-study about the usage of Vindigo, a company that publishes and develops information and entertainment applications for mobile phones. Basically, they turned the Palm into a “lifestyle device.” :“Eat, Shop and Play” was the first application that combined restaurant, store, and bar information. They now focus on wireless content delivery, a.k.a. location-based services such as the ability for mobile content providers to drive traffic to nearby physical stores. It's not only a matter of storing stuff about café and bars in a database. What is interesting, is that Vindigo users are an important source of content generation.

The company cites this feature as one of the reasons why Zagat’s found the Vindigo platform so attractive. Zagat’s model is based on user surveys that are sent out annually to between 5,000-10,000 reviewers in New York. With Vindigo’s platform, Zagat’s now has 100,000 reviewers rating local restaurants for their publications. Vindigo collects this information during the hotsync process. The company co-owns the content and shares it with Zagat’s. According to Edelmann, Vindigo is grabbing all of the data from the sync process but has not yet determined how to monetize the information.

Why do I blog this? It's an interesting example of how a company let users creating/modifying the content though the use of lcoation-based services.

Annotated google map

Engadget has a good take on how to make your own annotated multimedia Google map.

One of the great things about Google maps is it has its roots in XML. To translate for the non-web developers out there, it basically means Google maps are user hackable. This how-to will show you how to make your own annotated Google map from your own GPS data. Plus, you’ll be able to tie in images and video to create an interactive multimedia map. We’ll walk you through the steps we took to generate an annotated map of a walk we took recently through our hometown, now that it’s actually starting to get warm enough to want to walk about!

A must read for location-annotations freaks!

Location-based services and marketing

A new blog to check: location-based services in NZ by Clara Leung. It's mostly about here thesis entitled "'The Perceived Value of Location-Based Services in New Zealand Tourism'".

little bit more about myself - I'm a postgraduate student completing the second year of my Master of Commerce degree in Marketing at the University of Auckland. 2005 will be split between working hard on my thesis, 'The Perceived Value of Location-Based Services in New Zealand Tourism',

How to develop a collaborative mobile game

My EPFL co-worker Fabien wrote a postmortem report (.pdf) about our CatchBob! project in which he describes the whole development process. He presents how we designed CatchBob on two platforms (namely iPAQ and TabletPC) and how he implemented it. The report goes throught the whole thing, dealing with the game architecture, the user interface, the positioning feature as well as the communication tool (that allows to annotate the map). Here are the key points for people in a rush:

  • CatchBob! uses WiFi-enabled TabletPC as clients They use the Wireless Network sniffing capabilities of Place Lab to locate themselves by listening for radio beacons.
  • The positioning technique is based on a propagation model using the degradation of the signal strength of a radio wave over distance in space. We implemented a very simple triangulation using a centroid algorithm. It positions the user at the center of the scanned nearby access points by computing an average of their x, y location and taking the signal strength as a weight. We hence achieved to get a rough positioning accuracy (10-20 meters) which was sufficient for our needs.
  • CatchBob! is built on a client-server communication model. Every 30 seconds, the clients broadcast their positions, commands and annotations via a centralized server. The communication is done over SOAP. Clients are in a pull mode in order to retrieve and synchronize the data.
  • The map, annotation, and awareness rendering on CatchBob! interface is generated in Java2D on a static background displaying the campus.

The end of the report aims at enlarging the scope, discussing interesting issues such as the design of engaging technology (for the user's point of view), the relevance of 3D positioning and the huge potential of map annotation.

This document might be seen a good summary of how Fabien achieved the mobile game development. Besides, it's absolutely human-readables. Non-tech-savvy people should not be afraid to have a glance if they are interested in how to develop a mobile game.

Anne Galloway\'s comments about OPEN PLAN

At OPEN PLAN, anne galloway mentioned that she felt like being the only person coming fom social sciences attending the locative media event. She is indeed an anthropologist/ethnographer. As a cognitive psychogist, that is also something I can feel. Among all the discussions we attended, there seems to be some missing dimensions like what she is concerned with or even how those technologies modifies some group processes (in terms of social or socio-cognitive concerns for instance). In one of her recent post, she makes a brief summary of her thoughts. I just picked up her conclusion, which I find relevant:

in the end, I don't think that it's productive to talk about artists any more than it makes sense to treat all academics, corporate or government researchers as if they were the same. Clearly, we all share an equal ability and responsibility in keeping potential collaborations open and just, and this is no time to crush the diversity of cultures at hand.
