The article is called Depth of field: discursive design research through film written by Timo Arnall and Einar Sneve Martinussen. It is about the role of film in interaction and product design research, and the use of film in exploring and explaining emerging technologies.

In the last decade, interaction design has found itself in a rather unique position. As an interdisciplinary field, drawing upon many domains such as Human Computer Interaction (HCI), product and graphic design, informatics, art, engineering and critical practice, it has grown the potential to situate itself in a critical position between emerging technologies and culture. In particular, there are emerging modes of doing exploratory design research that result from the newfound relations between product, interaction and communications design.
In this article we discuss our design research activities that use film as a material for exploring, conceptualising and communicating with emerging technology. We analyse this through existing framings of audiovisual media in HCI, technology, and interaction design research. The central research question we address is how does audiovisual media enable new kinds of practice-based design research with emerging technology?

The relations between scientific advance and cinema are extremely close. Kirby proposes that film establishes achievability of scientific and technical discourses, and ‘cinematic depictions of future technologies demonstrate to large public audiences a technology’s need, viability and benevolence’. Historically, film has been a central part of the communication of new technology with interfaces mediated through film or video demonstrators. From televised events showing off household robotics at the 1939 New York World Fair to the invention of modern computing paradigms such as the mouse – in Engelbart’s ‘Mother of all demos’. Products too are often initially experienced through cinematic forms, from lifestyle commercials for Sony televisions, to explanatory ‘how to’ informercials for the Apple iPhone, to user-generated ‘unboxing’ videos on YouTube. The commercial film for the Polaroid SX-70 camera, directed by Charles and Ray Eames in 1972 is a fine example from design practice of new technology explained to the masses through a product commercial, conveying technology and experience combined into one sequence.

In this research we have used graphical, audiovisual, and time-based media as a tool, a material and a communicative artefact that enables us to approach complex, obscure and often invisible emerging technologies such as RFID. We give an account of how film has played an intricate role in the design research practice, from revealing the materiality of invisible wireless technology, to exploring prototypes in real-world settings, to communicating to a wide public audience.

In the article we propose that this kind of research with technology constitutes what we could call a ‘discursive design’ approach. The films below demonstrate design research approaches to RFID where film reveals and articulates complex subjects, through multiple genres, and for multiple audiences. By approaching design research in this way we may be able to explore emerging technologies through play, invention, imitation and parody in ways that are able to reveal and translate across many socio-cultural contexts.

Exploring materiality

The first films show a research approach that explores the materiality of RFID in experimental and highly aestheticised ways. These films emerged out of probing at the technology with the visual tools of photography and animation.

RFID is a largely immaterial technology, it is literally ‘black boxed’ into packaged components, and the qualities of its invisible radio fields are badly understood. The spatial and material aspects of RFID are important for design, in order to be able to create interactions and products that take advantage of the spatial and gestural properties of the technology.

In this film we use long-exposure photographs, light painting, layering and animation. These techniques support particularly expressive modes of explanation, the visualisations occupy a ‘real’ space and are sequenced in a way that provides an immediately graspable view into the spatial qualities of RFID. The use of documentary film form allows for the visual evidence to be laid out in sequences that contextualise, reveal and explain, the film is a highly communicative package for the methods and results.

This was originally written up here and here

In this related film, we show that the readable volume of an RFID tag can be shaped by actually manipulating the size and shape of the physical antenna. This demonstrates that the fundamental technology is not static and constant, and can be shaped through design. When taken together, these films are intended to build material knowledge of RFID, but also through their form, show how designers might begin to take some control over the technical materials, for aesthetic, interactional or functional purposes.

These creative deconstructions of RFID through film techniques point towards what might call a discursive design approach. Drawing on methods from critical design that unpack and re-conceptualise the technological material, combined with narrative and communicative approaches, we may begin to challenge some of the expectations and dominant understandings of RFID.

Communicating products and prototypes

The following product-focused films show technology in context through experiential and explanatory sequences, such as the use of motion diagrams and narrative ‘vignettes’ which convey experiences of using technological products in specific contexts.

Skål (Norwegian for Bowl) explores RFID interactions in a domestic media context, where it broadens the activity of television-based media consumption towards playful, physical engagement. Here film is used to communicate a functioning product prototype, while at the same time highlighting playful and tangible perspectives on RFID in use.

In Sniff we see the potential for reframing RFID technology through explanation and experiential representation of use and activities, and not by focusing on the technology itself. Here the use of cinematic qualities such as short depth-of-field and other stylistic devices such as quick-cut montages enable jumps in time and action that strongly reinforce the playful, exploratory perspectives on the technology.

Films as discursive objects

In this last set of films we wanted to create culturally relevant objects that could communicate to a broad audience.

This iPhone RFID film was created to engage with a large online discussion around Apple’s relatively new iPhone. We wanted to question the largely screen-based modes of interaction that the iPhone encouraged, and to subtly reframe the discussion around RFID to include media, toys, play and direct manipulation of objects in the world. The film was a speculative object from which to see the possibilities for the rich, playful interaction between mobile devices and the world.

Nearness offers a particular view of RFID and proximity interaction that playfully resonates with a history of the chain reaction film genre. It is designed to reach beyond a research or design community in order to provoke discussion and to increase awareness of the technological implications. It does this by parodying an existing popular cultural form in a way that inherently embeds the quality of the technology into the narrative. Originally this film was described here and here.

The making of

These films constitute more than documentation of the design research in Touch, they were the medium in which invention and reflection occurred. Audio-visual media allowed for the creation of products, spaces, objects, gestures and environments that supported our internal and external discussion and development around RFID.

This film shows some of the experiments, processes and film techniques behind the creation of the other films in the article. It shows that these design processes work within the material of film, where the analysis and reflection emerged through the design activity of filmmaking. As well as being highly communicative, film sequences provide a space to gather and articulate a set of ideas, providing a relatively stable outcome and further motivation within the design activity.

Summary

This is a body of design research work that demonstrates the communicative qualities of film, that represent physical objects and their interactive, tangible behaviours over time. Time-based, audiovisual media can combine both explanatory and experiential and contextualising power, and this opens up for prototypes, products and processes being externalised within a practice-based design research activity. We see the potentials for a kind of practice where the emphasis of design research is on communication and participation in public discourse.

We have shown how practice-based design research has the ability to create representations and communicative artefacts, as opposed to technological development or mass production. A communicative approach to interaction design is central to this research. It embodies the idea that the communication of ideas, concepts and arguments through mediated design artefacts is essential to both creating effective interactive products, and to provoking discourse in and around technology-centric research. The form of film – that embodies both a highly reflective design activity and communicative qualities – is an ideal medium for interaction design research, where it can coalesce knowledge around practices and processes and project towards potential futures. Film allows for a degree of probing, explanation and reflexive understanding of emerging technologies, but through its communicative qualities, also opens up for participation in broad social and cultural discourses around technology.

We have shown some perspectives on the role that film can play in exploring, conceptualising and communicating about emerging technology. Film can be used for cinematic explorations and enactments that enable speculation in practice-based design research, but we have also pointed towards the use of online mediation to support public discourse around ubiquitous technologies and materials.

In this film, Wireless in the world 2, simple visualisations of radio ‘spaces’ are overlaid into urban spaces. The film has been made as a follow up to this video experiment and has been specifically designed for exhibition in HABITAR at LABoral Centro de Arte y Creación Industrial.

Here is an excerpt from the exhibition description:

“Utopian and radical architects in the 1960s predicted that cities in the future would not only be made of brick and mortar, but also defined by bits and flows of information. The urban dweller would become a nomad who inhabits a space in constant flux, mutating in real time. Their vision has taken on new meaning in an age when information networks rule over many of the city’s functions, and define our experiences as much as the physical infrastructures, while mobile technologies transform our sense of time and of space.”

We’ve compiled a short sequence of some of the design experiments and tests in audiovisual media in the Touch project. Here we show some of the ‘behind the scenes’ tests and processes where we used cinematic/video/filmmaking tools as a means to uncover potentials and constraints around an emerging technology.

In these experiments we designed and invented spaces, objects, movements and audiovisual techniques that map and visualise the interactive phenomena of RFID. Many of the visual/cinematic concepts for Nearness and Immaterials were invented by exploring and experimenting with film.

Rather than investing time in creating complex software and hardware prototypes, the interactive experience can be quickly explored inside film compositing applications. These experiments have shown us that there is great value in having tools that offer efficient prototyping of interactions at an experiential level, that don’t need to rely on complex electronics or physical design. There is also value in working within a medium that is not tied to a specific location or a unique demonstrator, and that is editable, reproducible and transmissible allowing it to be shared freely and widely amongst a research group and across the internet.

This is the subject of a forthcoming paper that we’ll flag up here as soon as it is published.

The problem and opportunity of invisibility

RFID is still badly understood as an interactive technology. Many aspects of RFID interaction are fundamentally invisible; as users we experience two objects communicating through the ‘magic’ of radio waves. This invisibility is also key to the controversial aspects of RFID technology; once RFID antennas are hidden inside products or in environments, they can be invoked or initiated without explicit knowledge or permission. (See here for more on the invisibility of radio.)

But invisibility also offers opportunities: the lack of touch is an enormous usability and efficiency leap for many systems we interact with everyday (hence the success of Oyster, Suica and Octopus cards). But there is also the ‘magic’ of nearness one of the most compelling experiential aspects of RFID.

As designers we took this invisibility as a challenge. We needed to know more about the way that RFID technology inhabits space so that we could better understand the kinds of interactions that can be built with it and the ways it can be used effectively and playfully inside physical products.

The experiments

In order to study the readable volume around an RFID reader, we built experimental probes that would flash an LED light when they successfully read an RFID tag. The readable volume is not the same as the radio field, instead it shows the space within the field in which an RFID tag and an RFID reader will interact with each other.

One version of our probe containing a tag and LED light connected to the RFID reader that is being studied.

In a dark room, the probes were moved around the various RFID tags and readers that we wanted to study, with a camera taking long-exposure photographs of the resulting patterns of light. In this way we could build up layers by slicing through the field in different ways, creating animations that clearly reveal the spatial properties of this interaction.

These experiments were carried out in order to help us flesh out our own models of the technology, and were not intended to be scientifically accurate. So although they accurately reflect the behaviour of the technologies in the situations that we work with, there were no controlled environments or settings for generalisable technical accuracy.

Innovations ID 20

The Innovations ID 20 RFID reader has become one of the standard components in a lot of our work, it is small, robust and relatively cheap. So it has been very important for us to gain an understanding of the readable volume it produces when we embed the reader inside products such as Sniff and Skål.

Details: Innovations ID20 low-frequency EM4102 reader, 20mm circular EM4102 tag.

The resulting visualisation shows the way in which we have mapped the boundary of the readable volume, although a tag will read anywhere inside this, we have only mapped the edge for the sake of clarity. From the animation (see the video) we start to clearly see that the readable volume is made up of a strong central sphere, accompanied by a smaller lobe that surrounds the edge of the reader.

Oyster card

Mifare cards are one of the largest public applications of RFID, used in many transit systems around the world such as the Oyster and Suica cards. It has become common to have to touch in and touch out of subway stations, and many people have become accustomed to this interaction. So what does the readable volume around an Oyster card look like?

Details: Standard Mifare Oyster card, probed with a Sonmicro high-frequency reader.

With a square antenna inside the Oyster and the Sonmicro reader, we get an elongated main volume, accompanied by long skinny lobes on each edge of the card. This looks very different from the ID 20 mapping.

Orientation

The first two mappings held the reader and the tag parallel to each other, but we predicted that there would be a higher degree of complexity in the relationship if the tag and the reader moved in different orientations. The rig below was built so that we could control the angle between the reader and the tag, which moved along the surface of the table.

Details: Innovations ID20 low-frequency EM4102 reader, 50mm circular EM4102 tag.

There is clearly enormous physical complexity in this relationship, in the animation we can see the volume growing and shrinking, lobes turning into spheres, and vice-versa. But the animation gives us a very clear picture of the ‘throw’ of the reader onto a single two-dimensional plane, almost like looking at it as a torch.

Parallel and perpendicular

To show the two extremes of the relationship between orientation and the readable volume, we created two mappings, one with the tag parallel to the reader, and the other with the tag perpendicular. We mapped them using two different colours of LED: green for parallel and red for perpendicular.

Details: Innovations ID20 low-frequency EM4102 reader, 20mm circular EM4102 tag.

This image is a composite of the two mappings (see the video for animations of the two mappings separately) and it is clear that the readable volume is significantly different. When the tag is perpendicular to the reader, there is a sizeable gap in the middle of the reader where the tag will not read, creating two readable volumes side by side.

Conclusions

We have been continually challenging the ways in which RFID technology has been framed. It is incredible how often RFID is seen as a long-range ‘detector’ or how little relevant information is contained in technical data-sheets. When this information is the primary material that we are working with as designers, this is highly problematic. By doing these kind of experiments we can re-frame the technology according to our experience of it, and generate our own material knowledge.

One of the early motivations in this project was the way in which the animations really captured our tacit, embodied knowledge of the readable volume in a visual way, it was almost as if you could wave your hand through the floating green LEDs and feel them. Of course we had felt it hundreds of times in experimenting with tags and readers, but we had never seen it captured in an image, in a way that was communicable to others without having them try an interactive demonstrator. With this visual material, we can communicate about RFID in ways that we couldn’t previously.

So we hope that this work goes some way towards building better spatial and gestural models of RFID, as material for designers to build better products and to take full advantage of the various ways in which spatial proximity can be used. And with this better understanding we hope to be able to discuss and design for privacy and the ‘leakage’ of data in a more rigorous way.

The ‘Radiogenic’

Dunne & Raby introduce the idea of ‘Hertzian space’ in Design Noir and Hertzian Tales where they describe a landscape of electronic products creating a “new, invisible but physical environment”.

In Tunable cities they map the radio signals from domestic equipment such as babycoms and begin to examine the “role of electronic products in the aesthetic inhabitation of a rapidly dematerialising, ubiquitous and intelligent environment.” Here there are visualisations of radio fields as bright red spaces overlaid on the streets of Chiswick, London.

Although their work specifically avoided issues around making the invisible visible or visualising radio, it explored the “links between the material and the immaterial that lead to new aesthetic possibilities for life in an electromagnetic environment”.

“It might seem strange to write about radio, a long-established medium, when discussion today centres on cyberspace, virtual reality, networks, smart materials and other electronic tehcnologies. But radio, meaning part of the electromagnetic spectrum is fundamental to electronics. Objects not only “dematerialise” into software in response to minituarisation and replacement by services but literally dematerialise into radiation. All electronic products are hybrids of radiation and matter. [...] Whereas cyberspace is a metaphor that spatialises what happens in computers distributed around the world, radio space is actual and physical, even though our senses detect only a tiny part of it.”

As Matt Jones points out, they go on to coin the term “radiogenic” to describe objects that:

“function as unwitting interfaces between the abstract space of electromagnetism and the material cultures of everyday life, revealing unexpected points of contact between them.”

The Faraday chair offers a slightly more nuanced ‘visualisation’ of the boundaries of electromagnetic waves through a physical object. These works operate by visualising and making tangible the boundaries between electromagnetic phenomena, and as such, serve to highlight and create discourse around the issue of radio in emerging products and systems

Celebrating the magic of remote action

The language used to describe RFID interaction includes closeness, touch, proximity and pointing but there are few explorations of the way that RFID systems shape the gestural and tangible aspects of this interaction. Within Human Computer Interaction (HCI) there is some discussion of the spatial aspects of sensor technologies. For instance Ailisto et al (2003) discuss the ways that RFID creates contactless interactions on mobile phones: “Physical selection may be based on proximity or pointing. In the case of proximity, the selection is activated by bringing the activating device, e.g. a smart phone, close to the target device.”.

In the Touch project we have experimented with the spatial aspects of RFID interaction, developing a tacit design knowledge of the technology over time. At an early RFID hacking workshop with BERG/Schulze & Webb we experimented with playful interactions that involved “the magic of remote action” where invisible interactions triggered events in the world.

This is something we went on to explore in much more detail in the film Nearness, where the relationship between proximity and physical interaction is explored in detail.

In projects like the Graphic language for touch we have begun to find ways of representing invisible radio as a tangible design material in a functional setting.

And in her project the Bubbles of Radio (that emerged from our Fields and Seams brief) Ingeborg Marie Dehs Thomas imagined and visualised many fictional representations of radio fields including Bluetooth and RFID. These drawings provide a playful starting point for the discussion of our relationship to radio fields and the possibilities they open up for interaction.

Exploring and experiencing waves

The political, social and phenomenological aspects of the electromagnetic spectrum are a recurring theme within contemporary media art practice. For instance the exhibition Waves at RIXC tuned in to artistic engagements with the electro-magnetic spectrum and suggested that “artists should take control of the very principles and materiality of the ‘network waves’.”

A common practice is to translate radio space into an audible, sonic experience. In projects like ætherspace, Aeriology, Electroprobes and in many RFID projects some kind of probe that senses radio and offers audible output is held or attached to the body. The experience is then about being mobile, moving through and probing the world to discover how the lanscape and patterns of radio changes through space.

Then there are a number of visual, interactive visualisation projects such as the Wifi camera, the sightseeing telescope that reveals open wifi networks in urban space and the Free Network Visible Network project. In most cases the visual representations of the radio waves are merged and overlaid into optical or video backgrounds of the physical world, in a kind of ‘augmented reality’ genre.

In Edge Town by Ben Hooker and Shona Kitchen visual approaches are used to explore the ways in which we can “design interfaces with the flows of electronic data that run through our cities so that they can be experienced as an enriching complement to other, more ‘earthly’ phenomena.” Their garden-like visualisations represent the desire to turn these invisible flows into something more tangible. In another architectural approach, Pedro Sepulveda-Sandoval proposes the demarcation of public areas that are free of mobile phone signals, using the visual language of yellow/black warning tape.

Artists Ruth Jarman & Joe Gerhardt visualised many kinds of fields in Magnetic Movie, where the fields are seen animated as crackling, pulsing and swirling waves that uncomfortably inhabit physical spaces. This animation reinforced by a strong soundtrack that crackles in time with the motion is one of the most engaging and compelling visualisations of radio fields that we have seen.

Spatial and seamful sensors

For engineers and scientists, accurately modelling and visualising invisible radio fields, and engaging in antenna measurement is a difficult task, if not almost a ‘black art’. Using specialist robotic equipment and slowly measuring the intensity of radio signals at various points in space, it is possible to build up a three dimensional map of a radio field. There are also specialist 3D simulation tools that create models of radio fields and their interactions with physical material. These tools are mainly used to optimise the design of radio antennae, probe and problem-solve radio interference problems in electronic equipment and to assess safety issues with human exposure to radio systems.

In a paper called The spatial character of sensor technology Reeves et al (2006) describe the importance of understanding seams and spatiality in sensor-based systems. Although they concentrate on ‘torch-based’ interactions, their concerns are relevant for other sensor technologies:

“We are primarily concerned with the way in which seams between devices create a particular spatial character for the location in which they are deployed. This spatial character of seams derives from the use of spatially-embedded sensor technologies (e.g., GPS, Wifi, etc.) which are particularly prevalent in ubiquitous computing. Sensor technology plays a fundamental part in the creation of seams, and thus the character of the space in which such technology is deployed. The main issue, then, is how interactive and ubiquitous system design may appropriately address this essential spatiality.”

There is also a discussion of the ‘seamful’ character of many ubiquitous technologies.

Chalmers and Galani (2001) describes the ways in which “wireless networks have distinct physical characteristics such as a tendency to be absorbed by metal, water and other conductive materials, and a pattern of coverage that makes for a limited area of usable network connectivity.” They suggest that there may be a method or conceptual process of ‘seamful design’ that builds upon the way that “people accommodate and take advantage of seams and heterogeneity, in and through the process of interaction.”

“We critique the ‘disappearance’ mentioned by Weiser as a goal for ubicomp, and Dourish’s ‘embodied interaction’ approach to HCI, suggesting that these design ideals may be unachievable or incomplete because they underemphasise the interdependence of ‘invisible’ non-rationalising interaction and focused rationalising interaction within ongoing activity.”

There is something in this ‘seamful design’ process that may help us to understand of the way that we deal with the invisible aspects of radio-based interaction, and the ways that mental models are built out of these systems.

Sara developed a speech bubble approach to annotating physical objects, so that they look like they are ‘saying’ the audio and haptic feedback.

The representation of sound and vibration uses waveforms, showing amplitude over time. Although this is quite limited, it seems to be a useful shorthand for communicating a small range of tangible feedback.

On this note, I’m getting increasingly interested in the use of speech bubbles in popular media.

Right now I am sitting near fourteen objects sending and receiving radio signals, from Oyster cards to mobile phones and wireless routers in a multitude of overlapping and competing fields. Here we are creating communicative material that uses dashed-line abstractions to visualise the presence of wireless technologies in the everyday environment. What if we could see every field produced by an Oyster card or NFC enabled mobile phone for instance?

Using simple abstractions such as the dashed line and the kinds of visual language that we have previously proposed for RFID allow us to quickly communicate aspects such as the spatial properties of wireless technologies that are often overlooked. I’ve been using these images in presentations for a while, to sensitise designers and students to the spatial and embodied properties of RFID, Bluetooth and WIFI.

We are also experimenting with video, where the visualisations are part of an environment in a moving sequence. This is looking like a useful technique for making visual explanations of invisible materials.

(I’m a big fan of dotted or dashed lines, it’s a great visual trick for representing hidden things. Glad to see that Mike is taking up this language, we should develop it further!)

Here’s the description of the talk in full, the slides are available from slideshare and at Mike’s weblog:

Things have long had identifying marks, from silversmiths’ hallmarks to barcodes, but mating machine-readable identification with pervasive networking greatly increases the value of the marks.

For example, when a machine-readable identification method such as an RFID or a high-density visual code is combined with the wireless networking of a mobile phone, a new way of interacting with everyday objects is created. Once you have the capability uniquely identify anything immediately, you can attach meta information to it. Any meta-information. How much is this worth on eBay? Which of my friends has one? Will this go with my Mom’s china? Will it make me sick if I eat it? Was it made by children?

I call this digital representation as accessed through a unique ID, an object’s “information shadow” and I now see them attached to just about everything. Beyond getting meta information, however, lies an even more powerful concept: changing the physical object to a service, for which the thing you’re looking at is but a single instantiation of that agreement. It’s already happened to media, and to car-shared cars and shared bicycles in urban areas.

When this happens, the objects have to change at a fundamental level. They have to be designed differently and they have to be described and discussed differently. The “owner’s” relationship to the object changes. The very idea of ownership changes. The solid object grows a dotted line that is filled-in as-needed, when-needed, and with the features that are needed. This is not the same thing as renting or co-ownership, its anytime/anywhere nature-enabled by the underlying technology makes these new service objects fundamentally new.

Many recent products point in this direction, where objects such as the Amazon Kindle are useless without the service contract, where a Nabaztag/tag is an empty shell waiting for connection to a network full of personal information and social connections, and where NFC phones and RFID peripherals are just the touchpoints between the online and the offline.

“Pling Plong is a media player for stories and sounds, placed inside a pillow. It is designed for the home environment and is meant to stimulate children’s imagination and interest for books. Its low-tech appearance in form, material and its simple functions makes the pillow seem magical. The fact that you can lay your head on it makes the toy very calming and it is meant for relaxing play alone.”

Pling Plong is a simple but carefully crafted product, where everything from the textures of the fabric, to the graspability of the audiobook tokens to the sound design and audio levels have been explored and refined.

A video shows Silje’s experiments with characterful faces for the pillow, showing some of the exploration of different metaphors for RFID that are important aspects of making contactless interaction understandable and playful.

Pling Plong has been receiving a lot of attention online recently, being picked up by Trendhunter, Coolgadgetconcept, Yankodesign, Crecebebe, Talk2myshirt, Techviva, Ubergizmo, Weirdgizmos and more.

Some comments:

“The “low-tech appearance” should be given some stormy applause, because toys nowadays have nothing to do with the idea of play and having a good time.”

“We had our share on interactive pillow coverage like illuminated pillows or sound pillows but the Pling Plong pillow created by Silje Softing sticks out by it’s playful use of ’soft’ low tech to give an twist to the story telling for small children.”

“I hope that this will soon make its way to market and finally to our homes. I don’t have any kids but I’ll surely love a pillow that can sing to me!”

“Hurry up Silje Softing and find someone to manufacture this already! It could be the next big thing this holiday season.”

Silje’s weblog documents some of the making process, there are more photos of Pling Plong and a gallery making pictures here.

The most compelling content was the early visualisations of cellular networks, made by Motorola and AT&T at the time that they were trying to convince the FCC that mobile telephony was important.

It also features rather nice footage and photos of early mobile phone prototypes from Motorola, that displayed many contemporary form factors such as sliders and flip-phones. Worth checking out that full article for a bit of emerging tech/design history.

“With the new eTicketing System Touch&Travel from Deutsche Bahn (DB), the mobile phone serves as an electronic ticket on trains, buses, streetcars, subways, etc. The SIM cards inside the phones are provided by Giesecke & Devrient. The Touch&Travel project is initiated by Deutsche Bahn, the German railway, and the mobile operator Vodafone.”

This trial shows one of the ways that NFC changes the infrastructure required for a ticketing or payment service. In this case it is a lightweight, parasitic infrastructure that can fairly cheaply be added to other ticketing methods. The service relies on three elements:

• Passive NFC tags at stations that contain a unique identifier or geographic information for that location. In this case they are embedded inside what must be a cheap container of aluminium, a printed surface and glass. This doesn’t require power or a network connection, and serves the same function as a large, powered, and networked ticket machine.
• The mobile phone is the window into the service; it interprets the location/identification data, connects to the ‘cloud’ and provides an interface. This interface could show location, ticket prices, ticket options, time of journey, routes, transaction history, etc. Here there is the opportunity to create a service that offers more utility, value and experience than traditional ticketing.

• The mobile data network connects the user to the service, in many cases this data connection already exists, and doesn’t require infrastructural development. Of course here there are issues with underground metro systems that don’t offer mobile coverage.

  

  More details on the service/interaction design:

• By waving your NFC mobile handset over the so called Touchpoint before entering the train, located at the platforms, the system registers the beginning of a trip.
• The ticket is stored on the SIM card inside the mobile phone
• The conductor checks the ticket by scanning the phone with a portable reader.
• Having arrived at the destination, the handset is waved over the Touchpoint again. The system registers the end of your trip. The system processes the data and calculates the correct cost for the distance traveled.

• The passenger is billed once a month

  Of course the service requires that NFC handsets are easily available, or that the service is sold through SIM add-ons for existing mobiles (perhaps as an alternative to a contactless card like Oyster/Suica).

  I wonder how a service that relies so heavily on an ad-hoc infrastructure will be accountable to failure and who holds responsibility and the problem-solving ability for errors and misunderstandings?

  Thinking also about the parasitic; might multiple services compete with each other for approachable station space? In a de-regulated environment (I’m thinking of the UK here) who you touch might define what service you get…

The film is by Ruth Jarman & Joe Gerhardt of Semiconductor and commissioned by Animate Projects that remains on the forefront of “exploring the relationship between art and animation”.

  

  “Natural magnetic fields are revealed as chaotic, ever-changing geometries… Are we observing a series of scientific experiments, the universe in flux, or a documentary of a fictional world?” The stills don’t do the pulsing, crackling, moving visuals justice, I highly recommend that you go and watch the film.

  I am happy to see that in Article 5 they begin to address the invisible nature of RFID readers in public space:

  “RFID applications can technically operate without any visible or otherwise perceivable action [...]”

  They go further to recommend that there be mandated signage for RFID applications:

  “Where RFID applications are implemented in public places, RFID application operators should inform individuals on the use of RFID by providing at least a clear sign, accessible by all, that signifies the presence of RFID readers. Information should include, where appropriate, that RFID tags and readers may broadcast information without an individual engaging in any active action, a reference to the policy governing the use of the RFID application and a point of contact for individuals to obtain additional information.”

  While this sounds like a lot of information to get across in a sign, there may be ways of creating recognisable levels of security, various levels of private data use, and visible indications of the ways in which that data is stored or used (something along the lines of better food labelling examples). The success of this depends on creating a useful, user-oriented taxonomy of risks.
