EmoDetector App is online – Hear The Feeling of SMS

admin Schreibe einen Kommentar

EmoDetector, by University of Duisburg-Essen and Nokia Research Center, is an application that provides auditory cues in addition to the notification tone upon receiving an SMS based on a real-time analysis of a message’s contents, see [1].The application responds currently to the following characters sets:

  • 🙂 or 🙂
  • 🙁 or 🙁
  • 😉 or 😉
  • ok (case insensitive)
  • ?

There is a version for Nokia Series 60 phones and for Android, see the download site. Have a look at the http://www.emodetector.tom-lab.de/ website for more information.

CHI 2010 – Opening and Keynote

admin Schreibe einen Kommentar

2343 attendees came to CHI 2010 this year to Atlanta. Participants are from 43 countries and the colored map suggested that a good number came from Germany. Outside it really feels like spring 🙂

Overall CHI 2010 received 2220 submission across 13 categories of which 699 were accepted. In the paper and nodes categories there were 1345 submissions of which 302 were accepted (22% acceptance rate).

Genevieve Bell from Intel is a cultural anthropologist and she presented the CHI opening keynote with the title: „Messy Futures: culture, technology and research“. She is a great story teller and showed exemplarily the value of ethnography and anthropology research. One very graphical example was the picture of what are the real consumers – typically not living in a perfect environment, but rather living clutter and mess …

A further issue she briefly addressed was the demographic shifts and urbanization (soon three quarter of people will live in cities). This followed on to an argument for designing for the real people and for their real needs (in contrast to the idea of designing for women by „shrinking and pinking it“).

Genevieve Bell discussed critical domains that drive technology: politics, religion, sex, and sports. She argued that CHI and Ubicomp has not really looked at these topics – or at least they did not publish it in CHI 😉 Here examples were quite entertaining and fun to listen to the keynote – but it created little controversy.

Zeitgeist, GNOME Activity Journal etc. – Workshop at CHI

admin 1 Kommentar

On Saturday there was a workshop on monitoring, logging and reflecting. Know Thyself: Monitoring and Reflecting on Facets of One’s Life. In the workshop we discussed technologies and concepts for monitoring and using personal information. I started out with asking the question who knows what about you? The list is quickly growing (e.g. telecom provider, travel agent, super market, bank, mail provider, facebook, etc.) and so is the set of information they know about you. And it becomes clear that these entities keep a better record about an individual that the individuals themselves. Hence our central suggestion is that the user who is the one who could have easy access to all this information should make more of it and benefit from this information, for more see the paper [1] and the slides from the talk.

There is more information about the workshop and the topic in general:

My pick of the contributions is the Dunbar email mining system from Stanford.

PS: CHI is good for your health 🙂

Full Paper and Work in Progress at Percom 2010

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 the project we look at different options for visualizing context information – especially in ambient ways [2]. As display technologies we employed the Nabaztag and a digital picture frame.

Keynote by Pertti Huuskonen: Ten Views to Context Awareness

admin 1 Kommentar

Pertti Huuskonen from Nokia presented his keynote at Percom in Mannheim. I worked with Pertti in 1999 on a European Project TEA – creating context-aware phones [1].

After telling us about CERN and some achievements in physics he raised the issue that an essential skill of humans is that they are context-aware. Basically culture is context-awareness – learning how to appropriately behave in life is essential to be accepted. We do this by looking at other people and by learning how how they act and how others react. „Knowing how to behave“ we become fit for social life and this questions the notion of intuitive use as it seems that most of it is learned or copied from others.

He gave a nice overview of how we can context-awareness is useful. One very simple example he showed is that people typically create context at the start of a phone call.

One example of a future to come may be ubiquitous spam – where context may be the enabler but also the enabler for blogging adverts. He also showed the potential of context in the large, see Nokoscope. His keynote was refreshing – and as clearly visible he has a good sense of humor 😉

Opening of Percom, Keynote by Kurt Rothermel

admin Schreibe einen Kommentar

About 300 people are at Percom 2010, which is held in the palace in Mannheim – and amazing location! The conference had 233 submission and is truly international (1/3 of the papers come from Europe, 1/3 from America, and 1/3 from Asia/pacific) and highly competitive (acceptance rate of about 12%).

Kurt Rothermel from the University of Stuttgart presented the opening Keynote on Large-scale Context Management. He presented a set of interesting example from Nexus (Collaborative Research Center 627, Spatial World Models for Mobile Context-Aware Applications) that showed the challenge in large scale systems. The size of the problem is can be easily seen when considering that half the population of the planet is using a mobile device and hence needs to be located… Now imagine everyone is contributing sensor data at a rate of one update per minute… For more details on their work see their 2009 percom paper [1]. In his talk he gave also some references to other interesting research platforms in this space: SensorWeb/SensorMap by Microsoft [2] and SensorPlanet by Nokia [3].

NSF/EU workshop in Mannheim

admin Schreibe einen Kommentar

Mohan Kumar and Marco Conti organized an EU/NSF workshop on Future Directions in Pervasive Computing and Social Networking for Emerging Applications. They managed to get together an interesting set of people and the discussion in the break out session were very enjoyable and I got a number of ideas what really are the challenges to come.

There are the position statements on the web page and at some point the identified grand challenges will be available.

PS: blackboards are still highly effective 😉
