Human-Computer-Interaction

Monthly Archives: July 2008

From Friday to Sunday I was in Potsdam for the yearly Emmy Noether meeting organized by DFG (German Science Foundation). The Emmy Noether Program seems to me one of the most attractive funding options for early career researchers I know of (world wide).

This year I was in the preparation team for the meeting and was co-organizing one workshop where we discussed experiences with research funding in other countries and what ideas for improving current programs we can see. The workshop was on how we can benefit from having students rather than seeing them as “teaching load” – especially in… Continue reading

In my talk at ISUVR2008 I referred to an example where an insurance is monitor driving behavior and makes a tariff according to this. Some people asked me for more details andreferences, here they are…

My example was based on the pilot announced from the German insurance WGV. They planned to run a pilot with 1500 people using a GPS based monitoring devices. The box is mounted in the car and compares the current speed with the allowed speed limit and warns to reduce speed (if over the limit). If the driver is more than 12 times per year over… Continue reading

When we re-entered South Korea I saw guard looking with an infrared camera at all arriving people. It was very hot outside so the heads were very red. My assumption is that this is used to spot people who have fever – however I could not verify this.

Looking at the images created while people moved around I realized that for many tasks in activity recognition, home health care, and wellness this may be an interesting technology to use. For several tasks in context-awareness it seems straightforward to get this information from an infrared camera. In the computer vision domain… Continue reading

[see the whole set of photos from tour to North Korea]

From Gwangju we took the bus shortly after midnight to go for a trip to North Korea. The students did a great job in organizing ISUVR and the trip. It was great to have again some time to talk to Yoosoo Oh, who was a visiting researcher in Munich in our group.

When entering North Korea there are many rules, including that you are not allowed to take cameras with tele-lenses over 160mm (so I had to take only the 50mm lens) and you must not… Continue reading

Norbert Streitz – Trade-off for creating smartness

Norbert gave an interesting overview of research in the domain of ubicomp based on his personal experience – from Xerox PARC to the disappearing computer. He motivated the transition from Information Design to Experience Design. Throughout the work we see a trade-off between providing “smart support” to the user and “privacy” (or control over privacy). One of the questions if we will re-invent privacy or if it will become a commodity… As one of the concrete examples Norbert introduced the Hello.Wall done in the context Ambient Agoras [1]. This again brought up the… Continue reading

In the evening we had a great Korean dinner. I enjoyed it very much – and I imagine we have seen everything people eat in Korea – at some point I lost count of the number of different dishes. The things I tasted were very delicious but completly different to what I typically eat. Dongpyo Hong convinced me to try a traditional dish (pork, fish and Kimchi) and it was very different in taste. I was not adventures enough to try a dish that still moved (even though the movement was mariginal – can you spot the difference in the… Continue reading

The first day of the symposium was exciting and we saw a wide range of contributions from context-awareness to machine vision. In following I have a few random notes on some of the talks…

Thad Starner, new idea on BCIThad Starner gave a short history of his experience with wearable computing. He argued that common mobile keyboards (e.g. mini-querty, multi-tap, T9) are fundamentally not suited real mobile tasks. He showed the studies of typing with the twiddler – the data is impressive. He is arguing for cording keyboards and generally he suggests that “Typing while walking is easier… 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

When I arrived in Seoul at the airport I saw an interesting instance of embedded information. In Munich we wrote a workshop paper [1] about the concept of embedded information and the key criteria are:

  • Embedding information where and when it is useful
  • Embedding information in a most unobtrusive way
  • Providing information in a way that there is no interaction required

Looking at an active computer display (OK it was broken) that circled the luggage belt (it is designed to list the names of people who should contact the information desk) and a fixed display on a suitcase I was… Continue reading

Christofer Lueg (he is professor at the School of Computing & Information Systems at the University of Tasmania) and Trevor Pering (he is a senior researcher at Intel Research in Seattle) visited our lab this week. The timing is not perfect but at I am not the only interesting person in the lab 😉 Together with Roy Want and others Trevor published some time ago an article in the IEEE Pervasive Magazine that is still worthwhile to read “Disappearning Hardware” [1]. It shows clearly the trend that in the near future it will be feasible to include processing and wireless… Continue reading

Over the last years there have been many workshops and sessions in the ubicomp community that address the evaluation of systems. At Pervasive 2005 in Munich I co-organized a workshop on Application led research with George Coulouris and others. For me one of the central outcomes was that we – as ubicomp researchers – need to team up in evaluating our technologies and solutions with experts in the application domain and that we stay involved in this part of the research. Just handing it over for evaluation into the other domain will not bring us the insights we need to… Continue reading

Wolfgang just sent me another picture (taken by a colleague of him) with more information in the head-up display. It shows a speed of 180 km/h and I wonder who took the picture. Usually only the driver can see such a display 😉

For assistance, information and entertainment systems in cars (an I assume we could consider taking photos an entertainment task) there are guidelines [1, 2, 3] – an overview presentation in German can be found in [4]. Students in the Pervasive Computing class have to look at them and design a new information/assistance system that is context aware… Continue reading

Recently I came across a device that tracks the GPS position and has additionally a card reader (http://photofinder.atpinc.com/). If you plug in a card with photos it will integrate location data into the jpgs using time as common reference.

It is a further interesting example where software moves away from the generic computer/PC (where such programs that use a GPS track an combine it with photos are available, e.g. GPS photo linker) into a appliance and hence the usage complexity (on principle, did not try it out so far this specific device so far) can be massively… Continue reading

Wolfgang visited us for 3 days and we talked a lot about context-awareness in the automotive domain. Given the sensors included in the cars and some recent ideas on context-fusion it seems feasible that in the near future context-aware assistance and information systems will get new functionality. Since finishing my PhD dissertation [1] there has been a move towards two directions: context predication and communities as source for context. One example of a community based approach is http://www.iyouit.eu which evolved out of ContextWatcher /IST-Mobilife.

In his lecture he showed many examples how pervasive computing happens in the car… Continue reading
