Talk on Reducing the Social-Technical Gap in Location-Aware Computing

Today I gave a talk to my research group on the current state of my investigation. The presentation covered the topic of my DEA work, the early results of Tracing the visitor’s eye project and their implication for a field experiment taking advantage of digital footprints to support social navigation and seamful design. One personal goal of this presentation was to prepare my DEA defense in November and next week’s presentation of Understanding of tourist dynamics from explicitly disclosed location information at the 4th International Symposium on LBS & TeleCartography.

Towards Reducing the Social-Technical Gap in Location-Aware Computing (PDF)

Relation to my thesis: Trying to put the pieces of the puzzle together. The overall argumentation still lacks of coherence. I will need to make some choices and get rid of some themes to explore others profoundly. Most of all, my research questions are now outdated. I need to refine them. More on that later.

Reaching the Cloud of Connectivity

Relation to my thesis: The ubicomp of the present: situation provoked by the presence and absence of the “cloud of connectivity”.

Cyclist Dynamics in Barcelona

Over the weekend, I collected minute-by-minute data of the usage of Bicing (community bicycle program in Barcelona) bikes. The animation of these spatio-temporal data slightly reveals the dynamics of “cyclists” hanging out at the beach on Sunday afternoon (left) and then returning downtown in the evening (right).

Relation to my thesis: This little hack joins two of my current train of thoughts. The first on the complexity of deploying of urban (computing) infrastructures (Bicing is an excellent case study) and on the second: taking advantage of the digital traces left by people interacting with technologies to reveal and act upon the imperfections of the systems.

The Personal City

Andy Hudson-Smith Senior Research Fellow at the Centre for Advanced Spatial Analysis (CASA) published a new working paper out entitled ‘Digital Urban – The Visual City‘ in which he depicts the recent revolution in the production and distribution of digital artifacts which represent the visual city. Indeed, In the decrease in knowledge required to create and present geographical information is leading to a direct increase in the amount of information available. The emergence of georeferenced user-generarated data streams can by built into one Visual City with a personal flavor (i.e. Personal City):

In essence, we are but at the beginning of what will be a revolution in social, visual and informational data plotted geographically by general users. The rise of social networks provides us with the ability to look down on the city and view the activities that its citizens are involved in. This ability provides unique social data and an insight into how the citizens are thinking, working, and socialising.

Relation to my thesis: follow-up on Representing Spatio-Temporal Traces. What I find compelling about the emergence of the “personal city” is that the data do not come from the explicit annotation of the space, but rather from the residues of activities involving space (e.g. categorizing or sharing photos, communicating with a “subtle” location-awareness (twitter with a location attribute).

Representing Spatio-Temporal Traces

So Nicolas opened a pandora box by mentioning in Chronotopic visualizations: representing traces of people in spatial environments that the collection and representation of traces left by people in space through technologies is gaining momentum in location-based computing. In the past, this type of research aimed at understanding mobility and travel behaviors or predicting them (e.g. John Krumm’s work on “Predestination”). However, the collection of mobility data is time consuming and requests non-negligible efforts in setting-up and deploying surveys infrastructures. The costs and privacy issues prevented such studies to move beyond the scope of transportation research (see Jean Wolf’s Applications of New Technologies in Travel Surveys for a survey). Now, the accessibility to affordable wireless sensors and the emergence of the geospatial web are generating new types of “digital footprints” left by people in space though technologies. My Tracing the Visitor’s Eye project is one example among many. For instance, Danyel Fisher developed Hotmap to visualize where in the world people look at when they use Windows Live Maps (see Imaging the City workshop and Fisher’s Hotmap looking at Geographic Attention.

Now, as Nicolas questions, What types of affordances these new types of data/visualization create? First, they might be directed at professionals such as urban planners to build or refine their models, but also to any kind of industry that deploy services or infrastructures supporting mobility throughout a city. For instance, it might inform on the installation of Municipal Wi-Fi. A second line of investigation aims at feedback information back to the people in order to creating a control or feedback loop (i.e. a “mirror to ourselves”). This approach makes use of social navigation (”navigation towards a cluster of people or navigation because other people have looked at something“) to help individuals make more informed decisions about their environment. A few weeks ago in Rome, the MIT SENSEable City Lab closed the feedback loop as a first example of their Wikicity project. They aggregated various types data and visually mapped the density and movement of people, buses, taxis in real time throughout the whole of the Eternal City. “By revealing the pulse of the city, the project aimed to show how technology can provide the inhabitants with a better idea of their own city and can help adjust their behavior accordingly. In the context of the web, Mor Naaman translates the feedback loop into a “social media cycle” (see the slides of his presentation this week at Yahoo! Research Barcelona: How Flickr Helps us Make Sense of the World).

Last week at Picnic, Adam Greenfield gave a presentation “The City is Here for You to Use: Urban Form and Experience in the Age of Ambient Informatics” in which he discussed how everyware is already affecting cities. More specifically, he mentioned this new types of real-time information about cities and their pattern of use, visualized in new ways and that information can be made available locally on demand in a way that people can act upon.

Current scenarios for the application of these real-time visualizations mainly aim at facilitating a quick search or decision making such as determining a jogging path that corresponds to a combined query, or pedestrians that may eventually turn to interactive maps to avoid the masses or catch a bus. Other scenarios that take advantage of the temporal and social aspects of the traces could emerge. Such as providing an interactive tourist map of Switzerland based on Flickr traces revealing Zermatt, Interlakend and Davos and obscuring the non-relevant geographical location. But then, what are the scenarios beyond that?

A map of Switzerland by tourists for tourists?

Scenarios based on digital footprints lefts by people in urban environments seem to rely on the structure (urban environment), the past/current usage (social, navigation, wayfinding) and the content (POI). An application should intersect these layers in a meaningful way. However, delivering a pure mirror of the reality might be hard to reach. In some cases a meaning emerges from incomplete data patched by data mining, filtering and visualization algorithms. Their choice impact the perception of the data, potentially bringing an objective angle of the content provider and modifying the behavior. This is when read/write urbanism flirts with captology (aka persuasive computing). In other words, do the traces or the algorithms used to treat them that influence the individuals/citizens? Moreover, as discussed this week with Infovis.net‘s Juan Dünsteler, information visualization struggles between educating people in reading visualization and providing relevant metaphores. Therefore, the data presented and misunderstood can impact the decision making (Visualizing Geospatial Information Uncertainty: What We Know and What We Need to Know).

Relation to my thesis: A follow-up to Inferring Spatio-Temporal Activities in Urban Spaces, seeking inspiration for an upcoming infovis.net article and in preparation of a position paper for the Urban Mixed Realities: Technologies, Theories and Frontiers workshop.

The infrastructure Is Sensing You: Make People Question their Surroundings

The other day in Geneva I stumbled on this Obey Giant sticker placed in a public bathroom. Obey Giant is a street art campaign and an experiment in phenomenology by artist Shepard Fairey. Its sole purpose is to make people question their surroundings. Even though it might not designed to question ubicomp, the experiment is extremely relevant to the discourse on seams and invisibility created by technologies. Funnily, a couple of days before in Schipol I spotted a sign highlighting the every use of the infrastructure was recorded.

The infrastructure senses you: street art campaign (left), real-world case (right).

Journal of Location-Based Services

The first issue of the Journal of Location-Based Services is now online. It includes a very complete editorial lead article with A critical evaluation of location based services and their potential written by Jonathan Raper. There are several more issues of the journal queueing up to get into print, but the editors are still looking urgently for new LBS articles.

The call for paper, states a wide scope of interest:

Published research will span the field from location-based computing and next-generation interfaces through telecom location architectures to business models and the social implications of this technology. The diversity of content echoes the extended nature of the chain of players required to make location-based services a reality. Hence the journal’s aim is to bridge the research undertaken in industry and academia and promote communication amongst all in this diverse and rapidly growing sector

Relation to my thesis: a very fine place to publish.

Talk at Picnic '07

Last Friday at the Picnic conference, I participated to a panel on the The Near Future of Pervasive Media Experiences Bob Barker’d by Julian Bleecker. In my talk The design of everyday pervasive things, I discussed my observations on the deployment of the ubicomp of the present and then provided some thoughts on how it can affect the design of the “near future pervasive media experiences”. These observations are inspired by Donald Norman’s brilliant The design of everyday things. I translated the approach to critique and highlight the current issues in deploying pervasive, sensor-based environments.
