Enrico Rukzio visits us in Essen, projections everywhere

admin 1 Kommentar

On Wednesday and Thursday Enrico visited our group in Essen. He gave a part of my lecture on user interface engineering talking about mobile interaction with the real world. He include interesting examples, such as QR-code/NFC/RFID use in Asia, SixthSense project (camera projection system to wear around the neck) and handheld mobile projections. Enrico also explained some of the multi-tag work he does at Lancaster University [1].

In the lecture we talked briefly about future devices and interfaces. I mentioned one example: projection in the large – on building scale. The 3D visualization overplayed on buildings seem impressive – at least when looking at the video. NuFormer (http://www.projectiononbuildings.com/en) has created several interesting projections – but I never have seen one in the real – so far…

Looking at the 6th sense project and on the building projections we wondered how important in may become in the future to make research results in ubicomp/HCI understandable and accessible to a wide audience. Will this replace papers in the future?

Our PERCI Article in IEEE Internet Computing

admin Schreibe einen Kommentar

Base on work we did together with DoCoMo Eurolabs in Munich we have published the article „Perci: Pervasive Service Interaction with the Internet of Things“ in the IEEE Internet Computing special issue on the Internet of Things edited by Frédéric Thiesse and Florian Michahelles.

The paper discusses the linking of digital resources to the real world. We investigated how to augment everyday objects with RFID and Near Field Communication (NFC) tags to enable simpler ways for users to interact with service. We aim at creating a digital identities of real world objects and by this integrating them into the Internet of Things and associating them with digital information and services. In our experiments we explore how these objects can facilitate access to digital resources and support interaction with them-for example, through mobile devices that feature technologies for discovering, capturing, and using information from tagged objects. See [1] for the full article.

Talk by Florian Michahelles, RFID showcase at Kaufhof Essen

admin Schreibe einen Kommentar
Florian Michahelles, associate director of the AutoID-Labs in Zürich visited our group and gave a presentation in my course on Pervaisve Computing. He introduced the vision of using RFID in businesses, gave a brief technology overview and discussed the potential impact – in a very interactive session.

Florian and I worked together in the Smart-its project and during his PhD studies he and Stavros were well know as the experts on Ikea PAX [1], [2]. In 2006 and 2007 we ran workshops on RFID technologies and published the results and a discussion on emerging trends in RFID together [3], [4].

At Kaufhof in Essen you can see a showcase of using RFID tags in garment retail. The installation includes augmented shelves, an augmented mirror, and contextual information displays in the changing rooms. The showcase is related to the European Bridge project. …was fun playing with the system – seems to be well engineered for a prototype.

PS: Florian told me that Vlad Coroama finished his PhD. In a different context we talked earlier about his paper discussing the use of sensors to access cost for insurance [5] – he did it with cars but there are other domain where this makes sense, too.

Gregor showed the potential of multi-tag interaction in a Demo

admin Schreibe einen Kommentar

Gregor, a colleague from LMU Munich, presented work that was done in the context of the PERCI project, which started while I was in Munich. The demo showed several applications (e.g. buying tickets) that exploit the potential of interaction with multiple NFC-Tags. The basic idea is to have several NFC-Tags included in a printed poster with which the user can interact using a phone. By touching the tags in a certain order the selection can be made. For more details see the paper accompanying the demo [1].

Mobile Physical Interaction in the Wild

admin Schreibe einen Kommentar

The parking meter is some streets of Dublin are an interesting example of an interface following the basic idea of physical mobile interaction. As you see from the manual sticker – the first part is on the mobile phone: you call a number and then provide the place in which you are (by typing in a number). The second part is then on the ticket machine – till you get the print out. The amazing thing was I really saw people using it!

The user interface design is interesting as they use on the phone typical phone interaction (basically dialing an number) and keep the interaction with the ticket machine the same (except there is no need to insert coins) as it was before. But looking at some work we did in the PERCI project with DoCoMo in Munich we can tell that this is just the initial state of physical mobile interaction [1] – it can be expected that this will become more common!

Discussing project ideas at DoCoMo Euro-labs

admin Schreibe einen Kommentar

When I was still in Munich we worked on the PERCI project together with DoCoMo Euro-lab. This collaboration was very fruitful, as all partners had a deep understanding what they are doing an where technically excellent.

After my moving we finally found some time again to discuss project ideas. There are many options in the mobile domain and we found some interesting topics related to advertising where their expertise and our expertise could create interesting synergies.

Talk at the expert meeting on RFID and ubicomp

admin 1 Kommentar

In Frankfurt there was today an expert meeting on RFID and ubicomp organized by the Fraunhofer ISI. The purpose was a discussion about the impact of RFID technologies. The organizers will use our input to inform the creation of a document of technology assessment for the German parliament. The majority of the participants came from companies developing RFID technology or system.
In the first part of my talk “RFID and Beyond” I highlighted results from two workshops where I was a co-organizer: PTA2006 and Pertec2007 held at the Pervasive and Percom conferences. The results were also published in 2 papers in the IEEE Pervasive Computing magazine, see [1] and [2]. After this I showed some future visions and scenarios, namely the Smart-Its & MediaCup (foto from Birgit at Teco) [3], the SensorKnife [4], and the aware goods project [5]. Michael Müller extended the idea of the first aware goods project with a mobile phone based prototype – which we still have not written up for publication.

For me the technology assessment in Germany seems still often very much centred on threats and looks much less at opportunities. Looking at developments in Asia and in particular in Korea (e.g. U-City) I hope politics in Germany will in the future more often see the positive sides, too. Technology assessment can become a means to find opportunities and ideas to support innovation. For me it seems that a lot of the risks people attribute to RFID are not based on scientific results – is appears rather media induced… Positive cases such as wireless key systems and transport tickets (basically RFID technology) are in widespread use without much problems and great value for users – but not present in the public discussion.

One interesting estimated was that about 200 parts of the several thousands (e.g. safety related parts, large parts, parts that are often stolen, expensive parts) per car will tagged with RFID in the next 10 years to ease logistics, production and maintenance.
