Insights from network data analysis that yield field observations

Fabien Girardin

Editor’s note: This post for the April ‘Ethnomining‘ edition comes from Fabien Girardin @fabiengirardin who describes his work with networked/sensor data at the Louvre Museum in Paris. Based on this inspiring case study, he discusses the overall process, how mixed-methods are relevant in his work, and what kind lessons he learnt doing this.

Fabien Girardin is Partner at the Near Future Laboratory, a research agency. He is active in the domains of user experience, data science and urban informatics.

At the Near Future Laboratory we like to experiment and to go in different directions from the typical technology consultancy. We thrive on the involvement of multiple practices, and bet on the unordinary when it comes to question formulation, data collection and solution creation. After completing my PhD in Computer Science, I left the bounded disciplines of academia to embrace learning and connecting to the other “fields”, the other ways of knowing and seeing the world. Along with partners Julian Bleecker, Nicolas Nova and a network of tactical scouts, we formed a technology-based practice that combines insight and analysis, design and research, and rapid prototyping to transform ideas into material form.

Over the past 5 years, I have led investigations that aim to extract knowledge from the byproducts of people’s digital activities (i.e. network data, also often called digital shadows or digital footprints). That intangible material can take the form of logs of cellular network activity, aggregated credit card transactions, real-time traffic information, user-generated content or social network updates. Over time my contributions have evolved into helping transform this type of big data into insights, products and services. Whether applied for a client or as part of our self-started initiatives, this practice requires the basic skills of a “data scientist” (data analysis, information architecture, software engineering and creativity) along with a capacity to engage at the intersections with a wide variety of professionals, from physicists and engineers to lawyers, strategists and designers. The transversal incline of investigations on network data requires understanding the different languages that shape technologies, reporting on the context of their use, and describing people’s practices. The model of inquiry blends qualitative field observations with quantitative evidence often extracted from logs.

The investigation of network data involves along several steps multiple practices and skills from engineering, to statistics, design, strategy planning, product management and ethnography

Past projects have led us to exploit untapped data sources, uncover opportunities to transform data into insights, and materialize new services or products. Our method first contemplates datasets and techniques to approach our objectives. Then we develop tangible solutions that engage the project stakeholders in exploring different scenarios and solutions. It is through the experiences of  people with knowledge of the project domain that we are able to extract possible near-future changes and opportunities.

An uplifting experience – adopting ethnography to study elevator user experience


Rebekah Rousi

Editor’s note: This post for the April ‘Ethnomining‘ edition comes from Rebekah Rousi, @rebekahrousi who describes how the combination of qualitative and quantitative data collection was fruitful in her analysis of elevator usage. The post highlights the lessons she uncovered using both approaches.

Rebekah is a researcher of user psychology and PhD candidate of Cognitive Science at the University of Jyväskylä, Finland. With a background in visual arts and cultural studies, she is particularly interested in the psychology of user experience, affective human-technology interactions and the mental factors of design encounters.


I don’t know who was more moved by the experience of elevator design, me or the 50 people I interviewed. A few years ago a leading elevator design and manufacturing company gave me the task of examining how people experienced and interacted with elevators. The scope included everything from hall call buttons, to cabin interior design and perception of technical design. When given the brief, the artistic director noted country specific design features (or omissions) and even mentioned that there may be observable elevator habits I would want to take note of. Then, on our bidding a corporate-academic farewell she added that I might want to consider the psychology of the surrounding architectural environment. With that, I was left with a long list of to-do’s and only one method I could think of that would be capable of incorporating so many factors – ethnography. Ethnographic inquiry provides a framework in which the researcher’s own observations and experiences of the phenomenon under study – in this case elevator users’ behaviour in relation to the elevators, other users and the surrounding architectural environment – can be combined with “insiders'” opinions and insights.

So, I undertook the study in two of Adelaide’s (Australia) tallest office buildings (see the building entrances above). I chose these buildings for several reasons: 1) they are both highrises in which elevator usage is a necessity; 2) they are both non-residential office buildings in which factors such as occupational well-being, health and safety, and socio-cultural dimensions including power relations and hierarchies come into play. In order to gauge and explain user behaviour in relation to the tangible and non-tangible dynamics of the spaces, it is necessary to study sites which are similar in purpose. Further, both buildings housed the same brand of elevators. And both had only recently undergone elevator upgrades.

The data collection consisted of two separate parts: the mini-interviews (or verbal questionnaires) which lasted two to five minutes; and the field observations. The mini-interviews comprised the following topics: background information; mental factors such as current mood and personality type loosely based on the Myers-Briggs Type Indicator (social, organised, intuitive and analytical); Likert-scale opinion rating of elevator design elements; design suggestions; preferences (elevators or stairs?); security and safety; and habits. The components I was looking at in the field observation were: waiting and operating habits; interaction with design; interpersonal interaction; and movement flow.

April 2013: Ethnomining and the combination of qualitative & quantitative data

After the two previous editions (Openness and Stories to action), it’s now time for our April edition on combining qualitative and quantitative data.

While ethnography generally draws on qualitative data, it does not not mean that quantitative approaches shouldn’t be employed in the research process. Combining the two leads to a “mixed-method approach” that can take various forms: data collection and analysis can be either separated or addressed together, and each of them can be used in service of the other. Of course, this isn’t new in academic circles and corporate ethnography but there seems to be a renewed interest lately in this topic.

One of the driving forces of this renewed interest is the huge amount of information produced by people, things, space and their interactions — what some have called “Big Data“. The large data sets created by people’s activity on digital devices has indeed led to a surge of “traces” from smartphone apps, computer programs and environmental sensors. Such information is currently expected to transform how we study human behavior and culture, with, as usual, utopian hopes, dystopian fears and *critical sighs* from pundits.

Although most of the work of Big Data has focused on quantitative analysis, it is interesting to observe how ethnographers relate to it. Some offer a critical perspective, but others see it as an opportunity to create innovative methodologies to benefit from this situation. See for instance the notion of “Ethnomining” described by Aipperspach et al. (2006) in their insightful paper Ethno-Mining: Integrating Numbers and Words from the Ground Up:

Ethno-mining, as the name suggests, combines techniques from ethnography and data mining. Specifically, the integration of ethnographic and data mining techniques in ethno-mining includes a blending of their perspectives (on what interpretations are valid and interesting and how they should be characterized) and their processes (what selections and transformations are applied to the data to find and validate the interpretations).
