Smartphone Brain Scanner Available as Open Source

We are proud to announce the availability of the Smartphone Brain Scanner as open source under the MIT License.

SmartphoneBrainScanner is a framework for building cross-platform real-time EEG applications. Originally developed at Technical University of Denmark for collecting and analyzing signals from Emotiv EPOC headset, its extensible architecture allows working with various EEG systems and multiple platforms.

SmartphoneBrainScanner contains state-of-the-art techniques for working with multi-channel EEG signal in real-time, most notably source reconstruction methods with online adaptation to the noise level. Current implemented source reconstruction approaches cover the minimum-norm and low resolution tomography (LORETA) methods formulated in a Bayesian framework using a expectation-maximization scheme for hyperparameter estimation. The SBS2 source reconstruction is realized using a pre-build forward model connecting the cortical surface with the electrodes at the scalp. The current forward model provided with the software is a 3-spheres model obtained from the Matlab toolbox SPM8 using coarse spatial resolution and with sensor positions in accordance with the Emotiv EPOC system.

Source code and additional information is available on the smartphonebrainscanner project website.

ArtistRecommender winner app at Roskilde Labs

With the Roskilde ArtistRecommender app for Android, it is possible to get personal artist recommendations. Find the bands playing at Roskilde Festival which are similar to your taste in music, and explore new music at the Roskilde Festival.

      

The app is developed by three masters students in our Digital Media Engineering program at DTU Informatics under my supervision and was recently selected as one of four winner apps at Roskilde LABS ’12. Congratulations to Erik Beuschau, Michael Lunøe and Rasmus Theodorsen.

The DTU Roskilde site also has a short article (in danish) about the ArtistRecommender app.

Experiments with mobile apps at Roskilde Festival 2012

roskilde_2012This year at Roskilde Festival we are running a set of experiments by having festival participants using cool apps that have been developed by students in our lab:

  • Orange Fever – a massive social game where you infect others using Bluetooth and spread the ‘Orange Fever’
  • Hide and Seek – a game about meeting new people at Roskilde Festival by means of your smartphone
  • Roskilde Decibel – the app will collect ambient noise level showing the user the level of noise exposure s/he has been exposed to
  • MusicNerd – navigate between concerts in a tightly packed music schedule at Roskilde Festival 2012
  • SoundRate – rate your music preferences and experiences and provide useful feedback
  • ArtistRecommender – browse the artists at Roskilde Festival 2012 and get personal recommendations

All apps can be downloaded from Google Play.

Personal Informatics in Practice workshop at CHI 2012

Presentation of research paper “A Cross-Platform Smartphone Brain Scanner” at CHI 2012. The Personal Informatics in Practice: Improving Quality of Life Through Data workshop will be a gathering of researchers, designers, and practitioners exploring how to better support personal informatics in people’s everyday lives.

Guest Post on the Quantified Self Blog

quantifiedself_logoAuthors of articles for the Personal Informatics in Practice workshop at CHI 2012 in Austin, TX on May 6, 2012 have been invited to write a summary for the Quantified Self Blog. Our Blog Guest Post is a summary of our paper “A Cross-Platform Smartphone Brain Scanner”. It is authored by Jakob Eg Larsen, Arkadiusz Stopczynski, Carsten Stahlhut, Michael Kai Petersen, and Lars Kai Hansen.

The workshop will be a gathering of researchers, designers, and practitioners exploring how to better support personal informatics in people’s everyday lives.

My 5 minutes as a Quantified Self “Rock Star”

I presented our Smartphone Brain Scanner at the first Quantified Self Conference in Europe. Since I believe in the eating your own dog food mantra I was wearing the neuroheadset and using the smartphone brain scanner while giving my short Ignite Talk.

If you thought giving an Ignite Talk was stressful (a 5 minute presentation accompanied by 20 slides each displayed for 15 seconds, and the slides automatically advance) then try giving a live demonstration of your research prototype meanwhile :-)

Feeling like a rock star was during the break after the presentation where I got to talk to so many interesting people from the quantified self community that were interested in our research.

Roskilde ’11 ArtistRecommender gets attention

artistrecommenderThe Roskilde ’11 ArtistRecommender app developed by a team of DTU students Erik Beuschau, Michael Lunøe and Rasmus Theodorsen, as part of the festival courses in the Roskilde Festival powered by DTU Students initiative is now formally promoted by Roskilde Festival.

Also Berlingske has an article discussing ‘Smart apps for Roskilde Festival’ mentioning the Roskilde ’11 ArtistRecommender app.

Roskilde ’11 ArtistRecommender available

artistrecommenderThe Roskilde ’11 ArtistRecommender mobile app for Android is now available in Android Market. The app is developed by a team of DTU students Erik Beuschau, Michael Lunøe and Rasmus Theodorsen, as part of the festival courses in the Roskilde Festival powered by DTU Students initiative.

The mobile app allow the user to browse the artists at Roskilde Festival 2011 and get personal recommendations based on music preferences. Download the app from Android Market.
