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.

Wolfgang Spießl presented our CHI-Note

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 information systems [2]. One interesting finding is that you loose AND at the same time create opportunities for applications and practices. In the questions she hinted some interesting observations on driving in familiar vs. driving in unfamiliar environments using GPS units. Based on these ideas there may be an interesting student project to do…

The interest in Wolfgang’s talk and into automotive user interfaces in general was unexpected high. As you see on the picture there was quite a set of people talking pictures and videos during the presentation.

FacetZoom

admin 1 Kommentar

Raimund Dachselt presented FaceZoom, a widget for quick navigation, e.g. for a tree structure [1]. I liked his characterizing “a stacked treemap” – which explains nicely what the widget does and where the efficency can be found. At TEI’08 he gave already a nice private demo on how this can be linked to mobile devices and how to use a off-the-shelf phone with an accelerometer as controller.

Automotive SIG meeting at CHI

admin Schreibe einen Kommentar

This morning was a meeting of people interested in automotive user interfaces. It was an informal session where everyone could contribute. We had an interesting discussion anchored in the 100-Car Naturalistic Driving Study. My main arguments in the discussion were (1) that we have to take more care of context (awareness and prediction) to make smart controls and (2) that multimodality is a key concept to improve UIs.

We continued the meeting over lunch with people from BMW, Bosch and General Motors. I think everyone agrees that interactive in-car applications and hence user interfaces are a central topic that gains momentum at the moment. We discussed the option for doing a symposium next year on the topic.

How to Convince Girls that Computer Science is Cool?

admin Schreibe einen Kommentar

The number of woman starting a computer science degree in German is very low and this has been recognized on many levels as we (as an economy) loose at lot of potential. This problem can be found in many other countries. Leah Buechley suggested in her paper the LilyPad Ardunio [1] this issues by getting girls in building interactive electronics – as part of self-created fashion items. The idea of targeting technologies, so that they become attractive to girls – especially already in school – seems a promising approach to change the perception of what computer science means.

They use a microcontroller that can be sewn onto fabric and which can be connected to sensors, controls and actuators. The girls used them in a creative way to make interactive fashion, which they considered cool. Her course offered to young people aged 10-15 attracted about 90% girls (as far as I remember) – which is really impressive. I would be interested if a similar approach would work in Germany as well. Perhaps this could be an interesting project?

CHI Conference in Florence

admin Schreibe einen Kommentar

On Sunday afternoon I flew to Florence and we met up in the evening with former colleagues – CHI always feels like a school reunion 😉 and it is great to get first hand reports on what everyone is working currently. On the plane I met Peter Thomas (editor of Ubquitous Computing Journal) and we talked about the option of a special issue on automotive…

We have rented a house in the Tuscany Mountains together with Antonio’s group and collaborators from BMW research and T-Labs. Even though we have to commute into Florence everyday it is just great that we have our “own” house – and it is much cheaper (but we have to do our dishes).

The conference is massive – 2300 people. There is a lot of interesting work and hence it is not feasible to cover it in a few sentences. Nevertheless there are some random pointers:

In the keynote a reference to an old reading machine by Athanasius Kircher was mentioned.

Mouse Mischief – educational software – 30 mice connected to 1 PC – cool!

Reality based interaction – conceptual paper – arguing that things should behaves as in the real world – interesting concept bringing together many new UI ideas

Inflatable mouse – cool technology from Korea– interesting use cases – we could integrate this in some of our projects (not inflating the mouse but inflating other things)

Multiple Maps – Synthesizing many maps – could be interesting for new navigation functions

Rub the Stane – interactive surfaces – detection of scratching noises only using a microphone

Usability evaluation considered harmful – the every-year discussion on how to make CHI more interesting continues

It seems there is currently some work going on looking at technologies in religious practice. Over lunch we had developed interesting ideas towards remote access to multimedia information (e.g. services of ‘once’ local church) and sharing awareness. This domain is intriguing because churches often form tight communities and content is regularly produced and available. Perhaps we should follow up on this with a project…

Dairy study on mobile information needs – good base literature of what information people need/use when they are mobile

K-Sketch – cool sketching technique.

Crowdsourcing user studies – reminded me of my visit at http://humangrid.eu

Lean and Zoom – simple idea – you come close it gets bigger – nicely done
