It seems we have a lot of work in progress 🙂 and CHI is a great place to get feedback an talk to people about it.

Florian Alt and others from the summer school in Haifa pushed one of the ideas the developed there further. It is about interactions and technologies to motivate a more thoughtful handling of trash in urban areas [1].

Tanja Döring and Bastian Pfleging developed with Chris Kray in Nottingham the idea of tangible devices that have a functional core and a passive shell [2]. By this we image that future tangible products can be created… Continue reading

Together with Matthias Kranz and Carl Fisher we had a full paper at Percom 2010 – and I had the honor to present it [1]. The paper reports work that explored using the existing DECT (the wireless phone standard) infrastructure (available especially in Europe) as basic technology for localization. We compared DECT and Wifi and it is interesting that in most places you see more DECT based stations than Wifi. Overall it is a really interesting alternative to WLAN location.

From the joint work with Docomo-Eurolabs in Munich in the project AmbiVis we presented a work in progress poster. In… Continue reading

Given the technologies around us I sometimes wonder how close we are to a vision of ubiquitous computing. In this month IEEE Computer Invisible Computing column I had the pleasure to ask this question and share my view on it.

The short answer is: many technologies are ubiquitous but there is a lot more to come. In particular we see that many technologies (public displays, people centric sensing, and personal memory devices) are just around the corner and that they may have a large impact on how we perceive computing. For the long answer have a look at my article:… Continue reading

Robustness and durability are typical qualities that we aim for when building interactive prototypes and systems. Tanja and Axel explored what user experience we can create when we deliberately design something in a way that is ephemeral (=not lasting, there is a good German word “vergänglich”). Ephemeral User Interfaces are user interface elements and technologies that are designed to be engaging but fragile [1]. In the prototype that we showed at TEI 2010 in Cambridge the user can interact with soap bubbles to control a computer. Axel has some additional photos on his web page.

There is a short… Continue reading

Kati Mäkitalo-Siegl, Jan Zottmann, Frederic Kaplan and Frank Fischer organized a workshop that resulted in the book: Classroom of the Future. The book gives a very good overview and is in my view very well suited to run a seminar

We have one chapter in the book that talks about teaching beyond the classroom and outside a typical classroom using pervasive computing technologies [1]. Our chapter includes some of the work on tangible interaction we did in Munich, e.g. [2] and earlier experience where we did a school garden blog (in German only http://www.hcilab.org/albrecht/flachs-web/).

Details about the book and… Continue reading

We wrote an article on the automotive user interface conference that took place in Essen in September 2009. In the current issue of the IEEE Pervasive Computing Magazine this paper is published and gives an overview of the conference [1]. We hope our article highlights the key ideas that were presented at the conference.

Abstract. Cars offer an interesting but challenging microcosm for pervasive computing research and, in particular, for interaction with pervasive computing systems. Increasingly, researchers are looking at interactive applications in the car and investigating human-car interaction from a computer science-rather than an ergonomics or mechanical engineering-perspective. This… Continue reading

The 8th International Conference on Mobile and Ubiquitous Multimedia (MUM 2009) was held in Cambridge, UK. The conference is fairly specific and had an acceptance rate of about 33% – have a look at the table of content for an overview. Florian Michahelles presented our paper on a design space for ubiquitous product recommendation systems [1]. Our work contributes a comprehensive design space that outlines design options for product recommendation systems using mobile and ubiquitous technologies. We think that over the next years mobile recommendation systems have the potential to change the way we shop in the real world.… Continue reading

Together with Antonio’s group we looked at new forms of interaction beyond the desktop. The journal paper Tangible, Embedded, and Reality-Based Interaction [1] gives overview and examples of recent trends in human computer interaction and is a good starting point to learn about these topics.

Abstract: Tangible, embedded, and reality-based interaction are among novel concepts of interaction design that will change our usage of computers and be part of our daily life in coming years. In this article, we present an overview of the research area of tangible, embedded, and reality-based interaction as an area of media informatics. Potentials and… Continue reading

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… Continue reading

Dagmar presents her work on a design space for automotive user interfaces [1]. The design space allows to categorize user interface components and elements with regard to interaction agent, position in the car, and type of interaction. The design space can be used to compare interfaces and as tool for assessing new opportunities for interaction.

The design space is based on an analysis of more than 700 pictures from IAA 2007. The photos (and soon photos from IAA 2009) are available at https://www.pcuie.uni-due.de/AUI/

Ali presented our joint work with Nokia Rearch and DoCoMo Eurolab in the paper on sharing emotions [1] (the acceptance rate was about 20%). The research is motivated by the question how we can make communication more emotional and how we can enable digital craft creating. The idea is to have a new communication medium were a communication item is hand crafted and can carry emotion. The questions were encouraging and we hope to continue to work on this topic.

In the poster session we had two contributions. Christian Winkler showed his project on Flash-light interaction [2]. The idea is… Continue reading

On Tuesday I was at the German human computer interaction conference called Mensch und Computer. The keynote by Alex Kirlik was on Ethical Design (slides from his talk) and he showed how ethics extends beyond action to technology leading to the central question: Why should we build certain systems? His examples and the following discussion made me wonder whether “Ethics become the next Material for innovation”. Taking his example of 9/11 where old technology (air planes) and a different view on ethics was used to strike this is in contrast to previous/typical warfare where new technologies (e.g.… Continue reading

Uppsala in Sweden is still one of the places I have never been to – and this year I missed another chance: Interact 2009

From our group Florian was there an presented his paper on a parasitic applications for the web [1]. We also published joined work with ETH Zürich on a comparison of product identification techniques on mobile devices [2]. Heiko Drewes has submitted his PhD thesis on Eye-tracking for interaction and one of the early projects he did was now published at Interact. The idea is that the mouse courser is positioned to the position where your eye-gaze… Continue reading

Our group was involved in 3 papers that are published at Pervasive 2009 in Nara.

The first contribution is a study on public display that was presented by Jörg Müller from Münster. The paper explores display blindness that can be observed in the real world (similarly to banner blindness) and concludes that the extent to which people look at displays is very much correlated to the users expectation of the content of a display in a certain location [1].

The second short paper is a survey on car advertising and has been conducted in the context of the master thesis… Continue reading

We got a good set of submission for our workshop and had about 20 participants who joined us in Nara to discuss how pervasive computing will shape advertising in the future. The papers and a selection of talks is online on the workshop website: http://pervasiveadvertising.org

One question that was central to our discussion was: what is advertising and how is it different from information. It became quickly clear that there is a lot of information that has an influence on behavior and in particular shopping decisions and some of it is considered advertising but much is not. Hence it seems… Continue reading

Together Eva Eva Hornecker and Brygg Ullmer I was guest editor for a special issue of the International Journal of Arts and Technology (IJART) on the topic of Tangible and Embedded Interaction. The issue contains 6 papers that look at very different aspects of this topic.

Have a look at the editorial (it is openly accessible) for an overview of the papers in the issue.

As many of us I am skeptical of rankings (as long as I was not involved in making them 😉 Nevertheless sometimes they are interesting and helpful in assessing where to publish or what better not to read…

This morning we discussed where to publish some interesting work related to web technology (a follow-up of the UsaProx) and for the discussion such a list may have been helpful.  A colleague from Munich sent me the link to an Australian conference ranking and obviously they also have ranked Journals, too. They use A+, A, B, L, and C as… Continue reading

In the poster session we showed 3 ideas of ongoing work from our lab and got some interesting comments and had good discussions.  Ali presented initial findings from our experiments with multi-tactile output on a mobile phone [1]. He created a prototype with 6 vibration motors that can be individually controlled. In the studies we looked at what locations of the vibration elements and what patters can be spotted by the user. In short it seems that putting the vibration motors in the corners works best.

Florian showed ideas on counting page impressions on public advertising screens we sketched… Continue reading

For the second time we ran this year a workshop on automobile user interfaces and interactive applications in the car at the German HCI conference: http://automotive.ubisys.org/

In the first session we discussed the use of tactile output and haptics in automotive user interfaces. It appears that there is significant interest in this area at the moment. In particular using haptics as an additional modality creates a lot of opportunities for new interfaces. We had a short discussion about two directions in haptic output: naturalistic haptic output (e.g. line assist that feels like going over the side of… Continue reading

Last winter term I was teaching a class on Unconventional User Interfaces at the University of Linz as part of the MSc in Pervasive Computing. As part of the exercises the students had to do a project and write a paper on the topic in a group. This required to do a full round in the development (from idea creation to study).

Florian König and his group had an exciting idea for a novel form of advertisement. The user is mirrored in the advert and becomes a part of it. They implemented an interactive poster for a travel agent… Continue reading

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].

Paul presented after lunch our full paper on a development approach and environment for mobile applications that supports underlying user models [1]. In the paper he shows how you can create applications while programming by example where the development environment automatically adds a KLM model. In this way the developer becomes automatically aware of estimated usage times for the application. The paper is work that builds on our paper on KLM for physical mobile interaction which was presented last year at CHI [2]. The underlying technology is the embedded interaction toolkit [3] – have a look – perhaps it makes… Continue reading

Today we had our Pervasive at home workshop – as part of Pervasive 2008 in Sydney. We had 7 talks and a number of discussions on various topics related to smart homes. Issues ranged from long term experience with smart home deployments (Lasse Kaila et al.), development cycle (Aaron Quigley et al.), to end-user development (Joëlle Coutaz). For the full workshop proceedings see [1].

One trend that can be observed is that researchers move beyond the living lab. In the discussion it became apparent that living labs can start research efforts in this area and function as focus point for… Continue reading

Dagmar presented two work in progress papers at the poster session at CHI. One paper is a master thesis of Hema [1] and assess how we can personalize environments with coding preference into the Bluetooth friendly name. Here we were particularly interested into the acceptance in Germany and India. The second paper [2] was joint work with Nigel’s group from Lancaster. Here we look at targeted poster advertising and how preference information should be stored.

People take mobile devices into their cars and the amount of information people have on those devices is huge – just consider the number of songs on an MP3-Player, the address database in a navigation system and eventually the mobile web. In our work we looked at ways to design and implement search interfaces that are usable while driving [1]. For the paper we compared a categorized search and a free search. The was another paper in the session looking at practice of GPS use by Leshed et al. which was really interesting and can inform future navigation or context-aware… Continue reading

Paul Holleis presented at TEI’08 the results of the research he did during his internship at Nokia Research [1]. Over the summer Paul spent 3 month with Jonna Häkkila’s group in Helsinki, where he worked on two projects: combing touch and key-presses and wearable controls.

Technically both projects used capacitative sensing to recognize touch. In his paper “Studying Applications for Touch-Enabled Mobile Phone Keypads” [1] they added to common mobile phone buttons touch sensing so that multiple levels of interaction can be measured, such as approaching, touching and pressing. The paper additionally discusses new interaction possibility that arise… Continue reading

Alireza Sahami presented our CardiViz project at the demo session at Ubicomp. We were very happy that the project that was the result of our IPEC course on developing mobile applications was accepted as a demo.

Jonna Häkkilä, Anind Dey, Kari Hjelt, and I organized organized the Ubiwell workshop (Interaction with Ubiquitous Wellness and Healthcare Applications) at this years pervasive. Alireza presented another paper on heartbeat monitoring there:Florian Alt,… Continue reading

Heiko Drewes and Richard Atterer, collegues from university of Munich, have travelled to Interact 2007. Their emails indicate that the conference is this year at a most interesting place. The conference is in Rio de Janeiro, directly at the Copacabana. The conference was highly competitive and we are happy to have two papers we can present there.

Heiko presents a paper that shows that eye gestures can be used to interact with a computer. In his experiments he shows that users can learn gesture with eyes (basically moving the eyes in a certain pattern, e.g. following the outline of a… Continue reading

The last 3 days we were at the German HCI conference (Mensch und Computer) in Weimar. Overall the conference had a really interesting program (21 papers with an acceptance rate of 30%), presentations from usability professionals and a number of workshops.

Dagmar Kern presented our research on improving in-car telecommunication that was carried out together with people from BMW group in Munich. For details see:Dagmar Kern, Albrecht Schmidt, Michael Pitz, Klaus Bengler. Status- und Kontextinformationen für die Telekommunikation im Auto. Mensch & Computer 2007. Weimar, September 2007.Heiko Drewes showed the initial results of the studies on… Continue reading

At the German HCI conference (Mensch und Computer) I organized together with Paul Holleis and Klaus Bengler (BMW Group) a workshop on automotive user interfaces. We were surprised how many people work and research in this area in Germany and Austria.

The 9 talks showed a wide range of research results and questions ranging from activity recognition, search interfaces, cultural issues to research methods. Dagmar Kern presented our work on a new method for interviewing drivers at the gas station. Stefan Graf from BMW groups had an interesting demo on object oriented interaction and in-car text input.… Continue reading
