On Thursday 20th October Kjetil Nordby will defend his thesis ‘Between the Tag and the Screen: Redesigning Short-Range RFID as Design Material’ for the PhD degree at AHO. The title of the trial lecture is “Opportunities and challenges for SR-RFID as design material”.

Industrial and interaction designers are increasingly faced with new computational technologies that may be used as materials in designing. Such materials are important in design practices because they offer conditions for conceptualisation and production of new designs. However, new computational technologies are often very complex and not presented with the intention of supporting design practices. In investigating SR-RFID as a design material, we are faced with two important challenges. First, the available information concerning SR-RFID in relation to industrial and interaction design is limited and often oriented toward finished solutions rather than exposing potentials for designing. Second, it is difficult to find frameworks that show how to analyse such a technology so as to present it as a material specifically oriented toward industrial and interaction design.

The trial lecture starts 10 am, Disputation starts 12.00. It will be held in the main auditorium at the Oslo School of Architecture and Design

Presenting Touch at a event like this is a good opportunity to provide a glimpse into ongoing design and research and a chance to communicate to a broader audience. The talk focused on design as an approach to RFID and how we can use design to understand, communicate and explore emerging technologies.

The presentation consists of condensed presentation of RFID from a technical and material perspective and goes on to describe various aspects of designing with RFID. In this presentation we use the Touch-projects Bowl and Sniff to illustrate the process of designing RFID products. The presentation is available on Slideshare.

Last week Interaction Design students at the Oslo School of Architecture & Design participated in a Touch workshop where the brief was to design a playful, exploratory or characterful RFID interface. The emphasis of this workshop was on exploring the relationship between digital interaction through RFID and the material properties of physical objects.

The brief

This week we will be working with a technology called Radio Frequency IDentification or RFID. RFID is exciting for industrial and interaction designers because it is a cheap and simple technology that allows us to build quite advanced gestural and tangible interfaces. When an RFID tag is in the range of an RFID reader (usually about 10cm) it communicates a tiny amount of information, a simple short code that lets the computer know that it is present. This is usually used to identify an object, person or animal, for instance to open a door, to find the owner of a lost pet, to pay for a ticket, or to know if a product that is passing out of a shop door has been paid for.

RFID tags are tiny, fairly cheap and don’t require a battery. They can be embedded inside all sorts of materials easily and without much effort. RFID readers are also small and flat, enabling them to be embedded easily below surfaces such as wood, concrete or plastics. The only physical limitations are metal and water, which absorb radio signals and stop RFID systems from working effectively.

Designing playful RFID

You will design a physical interface that involves a reader, a few tags and a Tikitag application.

Industrial and interaction designer’s haven’t been working with RFID for very long. So RFID systems are usually dull and lifeless, with ordinary plastic or paper tags and flat plastic readers. There needs to be more experimentation with the physical aspects of RFID interfaces in applications such as toys, appliances and domestic interfaces. There may be great playful applications of the technology that have not yet been explored.

You must design the physical relationship between the tag, the reader and the resulting action. Your objects must be finished with quality and material choices that match the intended use and context of the application (such as waterproof plastics for the bathroom or turned wood for the coffeetable).

Methods

You will each choose a different application from our list of Tikitag applications. Sketch out ten ways in which the tags and the reader in that application should look, feel and behave. What kind of approach is most suitable? Should it be characterful, understated, loud? What other kinds of objects should it reference? List out the kind of materials that would be suitable for such an application.

Design one set of tags and a reader for your application. Think about size, shape, durability, surface texture, and the relationship between the reader and the tag. How do the objects relate to each other? How do the objects and the reader fit together? What metaphors and associations can you draw upon, are they like keys, do they encourage swiping, caressing, tickling? How will a user manipulate the objects? Will they have to place them in certain positions or sequences to achieve different results?

Some quotes:

Vinner Design for alle: Kosehunden og spillet Sniff av Sara Johansson

“FOLSOM HUND. -Jeg tenkte litt på å lage en rotte, men da jeg tok kontakt med Tamtbartun kompetansesenter for blinde for feedback i designprosessen, mente de at det var lurt at det var en hund, siden mange av barna skal forholde seg til en hund senere i livet, sier industridesigner Sara Johansson (34), som fullførte studiene på Arkitekthøgskolen i Oslo forrige semester.”

“Hun har utviklet spillet Sniff, et kosedyr som identifiserer radiofrekvenser. Når Sniff snuser på en gjenstand lager den forskjellige lyder og vibrasjoner. Med denne teknologien har Johansson designet både et Memory-spill og en lek der man kan gjemme klistremerker rundt om i huset. Hunden kan identifisere ulike type stemminger som glede og sinne, takket være RFID-teknologi.”

“Nå jobber hun med å utvikle prototypen, både for å gjøre hunden mer robust og for å få inn en Mp3-spiller som kan inneholde flere lyder. Foreløpig er det mest blipp og blopp. -Jeg synes ikke det finnes noe verre enn dyr og leker som snakker. Jeg vil heller forsøke å abstrahere noen lyder som passer til sniffs karakter. Finne en stemme som kan gi ham liv, sier designeren.”

“Johansson, som kommer fra Umeå i Sverige, begynte å sy forskjellige type kosedyr da hun var 10-12 år. Det er med andre ord ikke helt tilfeldig at bullterrieren Sniffs pels består av typisk syttitallsvelur og cordfløyelprikker.

– Det var også viktig for meg at ikke kosedyret skulle se ut som en teknologisk leke, sier hun. Da Blindesenteret hjalp Johansson med å finne testpersoner for spillet, var de blinde og svaksynte barnas foreldre opptatt av hundens potensial for å uttrykke følelser.

– Noen av foreldrene mente at det kan være vanskelig å snakke om følelser. De kan for eksempel ikke tollke følelser i barnas blikk. Jeg tror Sniffl kan være et nyttig redskap i så måte. Barna var mest opptatt av å kjenne på selve hunden. Det var viktig at den hadde fire ben, hale og snute. Jeg fikk lov til å gjøre noe noe med det, sier Johansson.

– Hva betyr det for deg å vinne Unge Talenter?

– Det er noe av det fineste du kan vinne her i Norge, men det betyr først og fremst at noen har tro på prosjektet. Nå har jeg en god grunn til å fortsette arbeidet. Jeg håper det kan bli enklere å få spillet i produksjon, eller å skaffe en investor.”

Previously Sniff won AHO’s prize for Design for all, and has been included as one of Dagbladet’s trends for 2008.

Here is the feedback from the jury, in Norwegian:

“Sniff er et veldig morsomt spill som inkluderer alle. Det er lett å forstå, og stiller krav til barna uten å kreve forkunnskaper eller stigmatisere. Bruk av RFID-teknologi, som sender ut et signal og skaper kommunikasjon mellom kosedyret og figurene, gjør spillet til en innovasjon på sitt område.

“Tilgang til forskjellige brikker med ulike lyder og funksjoner, gir spillet imponerende mange variasjonsmuligheter. Det fins også RFID-klistremerker, som man kan gjemme rundt i huset og lage enda en ny lek med. Sniff er rett og slett en kjempegod idé, som på en nyskapende måte tar i bruk ny og spennende teknologi.”

“Utformingen er tydelig rettet mot barn, men spillet kan utmerket godt brukes av alle mennesker i alle aldersgrupper. Det egner seg svært godt som en døråpner mellom mennesker når språkbarrierer eller fysiske begrensninger hindrer dem i å kommunisere.”

If you want to try out Sniff for yourself, the exhibition will be open from 27 March until 27 April at DogA in Oslo. The Bowl project will also be exhibited.

If you like Sniff you will be happy to hear that Sara Johansson and the Touch project are developing Sniff 2.0 that includes a revised physical design, new feedback and interactional possibilities.
