This year we have the chance to share some of our research with the community at CHI2012. The work focuses on usable security ([1] and [2]) and public display systems [3]. Florian got together with the researchers from T-Labs a best paper award for [3].

Please have a look at the papers… I think it is really worthwhile.

Increasing the security of gaze-based graphical passwords [1] With computers being used ever more ubiquitously in situations where privacy is important, secure user authentication is a central requirement. Gaze-based graphical passwords are a particularly promising means for shoulder-surfing-resistant authentication, but… Continue reading

At the automotive user interface conference in Salzburg we presented some of our research. Salzburg is a really nice place and Manfred and his team did a great job organizing the conference!

Based on the Bachelor Thesis of Stefan Schneegaß and some follow-up work we published a full paper [1] that describes a KLM-Model for the car and a prototyping tools that makes use of the model. In the model we look at the specific needs in the car, model rotary controllers, and cater for the limited attention while driving. The prototyping tool provides means to quickly estimate interaction times.… Continue reading

Over the last year we looked more closely into the potential of eye-gaze for implicit interaction. Gazemarks is an approach where the users’ gaze is continuously monitored and when leaving a screen or display the last active gaze area is determined and store [1]. When the user looks back at this display this region is highlighted. By this the time for attention switching between displays was in our study reduced from about 2000ms to about 700ms. See the slides or paper for details. This could make the difference that we enable people to safely read in the car… but before… 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

Following our first workshop on this topic in Nara during Pervasive 2009 earlier this year we had on Friday the 2nd Pervasive Advertising Workshop in Lübeck as part of the German computer science conference Informatik 2009.

The program was interesting and very diverse. Daniel Michelis discussed in his talk how we move from an attention economy towards an engagement economy. He argued that marketing has to move beyond the AIDA(S) model and to consider engagement as central issue. In this context he introduced the notion of Calm Advertising and interesting analogy to Calm Computing [1]. Peter van Waart… Continue reading

At the evening event of MobileHCI2009 the best paper awards were presented. The best short paper was “User expectations and user experience with different modalities in a mobile phone controlled home entertainment system” [1]. There were two full papers that got a best paper award: “Sweep-Shake: finding digital resources in physical environments” [2] and “PhotoMap: using spontaneously taken images of public maps for pedestrian navigation tasks on mobile devices” [3]. We often look at best papers of a conference to better understand what makes a good paper for this community. All of the 3 papers above are really well done… Continue reading

Yesterday we discussed (again during the evening event of MobileHCI2009) how hard it would be to support the process of writing a high quality research paper and essays. In many conference there is a very defined style what you need to follow, specific things to include, and certain ways of how to present information. This obviously depends on the type of contribution but within one contribution type there could be probably provided a lot of help to create the skeleton of the paper… In many other areas Sounds like another project idea 😉 You ought to keep your essay presentation… 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

On Saturday we went to Garmisch and walked up to Höllentalklamm (a nice canyon) and had lunch at Höllentalangerhütter. Our GPS tracking data from the canyon was pretty poor (as one would expect as the canyon is in parts only a few meters wide).

Observing other hikers (especially people who did the larger tours) it was very interesting to see how maps are used in social situations – planning, discussion, reflection, and storytelling (this time n>10). It is hard to image how this experience can be replaced by an implementation on a mobile device.

Will we have to wait till we have 1 meter by 1 meter foldable e-ink displays with 200dpi? Or are there other means to implement a good hiking map on a mobile phone screen? There is a… Continue reading

Meeting with other researchers that run or have run Emmy Noether research groups is very different from normal conferences and meetings. The participants are across all disciplines – from art history to zoology 😉 The meeting focuses mainly on strategic, political, personal, administrative and organizational issues when starting a research career. This year we had child care organized during the meeting and Vivien came with me to Potsdam.

On Saturday night I learned that we (our galaxy) will eventually collide with the Andromeda Galaxy (but after our sun is out fuel – so I do not worry too much). Vivien… Continue reading

For the 1st International Conference on Automotive User Interfaces and Interactive Vehicular Applications (AutomotiveUI 2009) we got many quality submissions. The review process is now complete and we accepted 12 full papers and 10 notes for oral presentation at the conference. The list of accepted contributions is online at auto-ui.org.

As a number of people have asked if the still can submit to the program and as many of the rejected papers raise interesting aspects we decided to have Posters as a further submission category. We have a continuous submission process for poster abstracts till Sept 1st 2009. Earlier submissions… Continue reading

On his way from Eindhoven to Zurich Morten Fjeld was visiting our group. It was great to catch up and talk about a number of exciting research projects and ideas. Some years ago one of my students from Munich did his final project with Morten working on haptic communication ideas, see [1]. Last year at TEI Morten had a paper on a related project – also using actuated sliders, see [2].

In his presentation Morten gave an overview of the research he does and we found a joint interest in capacitive sensing. Raphael Wimmer did his final project in Munich… Continue reading

Pervasive 2009 had a really exciting program and provided a good overview of current research in pervasive and ubiquitous computing. Have a look at the proceedings of the pervasive 2009 conference. The Noh theater in Nara was a very special and enjoyable venue and it was organized perfectly – as one would expect when travelling to Japan.

The idea of having short and long papers together in the main track worked very well in my view. The number of demos and posters was much higher than in the years before – and that was great and very inspiring. Have… Continue reading

Together with Rene Mayrhofer and Alexander De Luca I organized a technical training at the European Patent Office in Munich. In the lectures we made the attempt to give a broad overview of recent advanced in this domain – and preparing such a day one realizes how much there is to it…. We covered the following topic:
  • Merging the physical and digital (e.g. sentient computing and dual reality [1])
  • Interlinking the real world and the virtual world (e.g. Internet of things)
  • Interacting with your body (e.g. implants for interaction, brain computer interaction, eye gaze interaction)
  • Interaction beyond the desktop, in… Continue reading

Comparing prices and finding the cheapest item has been a favorite application example over the last 10 years. I have seen the idea of scanning product codes and compare them to prices in other shops (online or in the neighborhood) first demonstrated in 1999 at the HUC conference. The Pocket BargainFinder [1] was a mobile device with a barcode reader attached that you could scan books and get a online price comparison. Since then I have seen a number of examples that take this idea forward, e.g. a paper here at HotMobile [2] or the Amazon Mobile App.

The… Continue reading

What is a simple and cheap way to get from Saarbrücken to Linz? It’s not really obvious, but going via Stansted/Cambridge makes sense – especially when there is the conference on Tangible and Embedded Interaction (www.tei-conf.org) and Raynair offers 10€ flight (not sure about sustainability though). Sustainability, from a different perspective was also at the center of the Monday Keynote by Tom Igeo which I missed.

Nicolas and Sharam did a great job and the choice to do a full day of demos worked out great. The large set of interactive demos presented captures and communicates a lot… Continue reading

Following the workshop I got a few questions on what the important papers are that one should read to start on the topic. There are many (e.g. search in google schoolar for tangible interaction, physical interaction, etc and you will see) and there conference dedicated to it (e.g. the tangible and embedded interaction TEI – next week in cambridge).

But if I have to pick two here is my joice:

[1] Ishii, H. 2008. Tangible bits: beyond pixels. In Proceedings of the 2nd international Conference on Tangible and Embedded interaction (Bonn, Germany, February 18 – 20, 2008). TEI ’08.… Continue reading

This afternoon Gordon Bolduan from Technology Review was visiting the lab. We talked about haptic and tactile interfaces and showed some demos (e.g. navigation with tactile cues).  When preparing for the visit I looked for some good examples of tactile interaction – and interestingly there is more and more work out there that has the potential to change future interfaces and means of communication.  Recent work on connecting people [1] and [2] at the boundary between computing and design shows new options for emotional communication. 

We used in our work multiple vibration motors and explored the potential… Continue reading

As one issue this morning we came across issues related to privacy. In particular it seems that social network analysis based on behavior in the real world (e.g. the reality mining project [1]) is creating serious interest beyond the technology people. Beyond measuring the frequency of encounters qualifying the way people interact (dominance, emotion, …) will reveal even more about social networks… 

In our discussion I made a reference to a book: “The Transparent Society” by David Brin. Even Though it is now nearly 10 years since it was first published I still think it is an interesting starting… Continue reading

Visiting Dublin is always a pleasure – even if the weather is rainy. Most of the day I was at Trinity College reading master theses (which is the second best part of being external examiner, best part is to have lunch at the 1592 😉 In the evening I met with Aaron Quigley and we talked about some ongoing display and advertsing projects in our groups. He told me about one of their recent workshop papers [1] on public displays where they investigated what people take in and what people remember of the content on displays in an academic… Continue reading

Over the last days there were a number of interesting papers presented and so it is not easy to pick a selection… Here is my random paper selection from Ubicomp 2008 that link to our work (the conference papers link into the ubicomp 2008 proceedings in the ACM DL, our references are below):

Don Patterson presented a survey on using IM. One of the finding surprised me: people seem to ignore “busy” settings. In some work we did in 2000 on mobile availability and sharing context users indicated that they would respect this or at least explain when… Continue reading

During mobile HCI I came across many interesting things (that is why one goes to conferences 😉 here is a selection of papers to look at – if you have more time it is worthwhile to look at the whole proceedings of mobile HCI 2008 in the ACM DL.

Gauntlet: a wearable interface for ubiquitous gaming – exploring a new gaming UI for gestures.

Mobile phones as artifacts children use in their games are discussed. Shows again how creative children are 😉

An Investigation into round touch screen Wristwatch interaction – interesting topic and good example how to do… Continue reading

Last year Paul did an internship a Nokia in Finland. He worked there on the integration of capacitive sensors in phones and clothing. After Paul was back we jointly followed up on the topic which resulted in an interesting set of guidelines for placing wearable controls [1].

The paper gives a good overview of wearable computing and interaction with wearable computers. In the work we focused on integrating touch sensitive controls into garments and accessories for a operating the music player integrated in a phone. The study showed that there are prime locations where to place controls on their body:… Continue reading

Since Enrico Rukzio (my first PhD student) went to Lancaster he discovered and advanced a very exciting topic for mobile interaction: mobile projector/projector phones. His group has a great presencs at this year’s mobile HCI (3 demonstrations, 2 short papers, 2 full papers, a workshop). In time for the conference the first projector phone appeared on the market (Cking Epoq EGP-PP01) – as to highlight the timeliness of the work.

The mobile projector study [1] revealed several interesting aspects. 1) it is faster to browser on the phone screen than using a project, 2) users do a lot… Continue reading

Yesterday I arrived in Gwangju for the ISUVR-2008. It is my first time in Korea and it is an amazing place. Together with some of the other invited speakers and PhD students we went for a Korean style dinner (photos from the dinner). The campus (photos from the campus) is large and very new.

This morning we had the opportunity to see several demos from Woontack’s students in the U-VR lab. There is a lot of work on haptics and mobile augmented reality going on. See the pictures of the open lab demo for… Continue reading

While browsing the equator website I came again across an interesting publication – I had seen two years ago at MobileHCI – in the domain of pedestrian navigation [1]. The Basic idea is to use a collection of geo-tagged photos to provide visual cues to people in what direction they should go, e.g. “walk towards this building”. This is an interesting application linking two concepts we discussed in the part on location in my lecture on pervasive computing. It follows the approach of augmenting the user in a way that the user does what he does well (e.g. matching visual… Continue reading

Using electrodes to detect eye movement and to detect reading [1] – relates to Heiko’s work but uses different sensing techniques. If the system can really be implemented in goggles this would be a great technologies for eye gestures as suggested in [2].

Utilizing infrastructures that are in place for activity sensing – the example is a heating/air condition/ventilation system [3]. I wondered and put forward the question how well this would work in active mode – where you actively create an airflow (using the already installed system) to detect the state of an environment.

Further interesting ideas:
