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

SmartphoneBrainScanner2 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.

SmartphoneBrainScanner2 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 smartphonebrainscanner2 project website.

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 the Digital Media Engineering program at DTU Informatics 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.

This 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.

Authors of articles for the Personal Informatics in Practice workshop at CHI 2012 in Austin, TX on May 6, 2012 have been asked 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.

Our Smartphone Brain Scanner has received international recognition been selected for the Netexplo 100 2012.

Netexplo 100 recognizes the most significant and promising digital projects around the world. The full list of innovations is here. The mentioning of the Smartphone Brain Scanner is here.

We have received a grant from the H. C. Ørsted Foundation (in danish: H. C. Ørsteds Fond for Teknisk-Videnskabelige undersøgelser) to support our research in human behavior and mobility modeling using smartphones and wearable sensors.

On Nokia Conversations Ph.D. student Arek Stopczynski “talks us through this innovative breakthrough product that works by connecting a commercially available wireless 14-channel EEG headset to a Nokia N900 smartphone”.

More information about the project is available here.

“YOU can now hold your brain in the palm of your hand. For the first time, a scanner powered by a smartphone will let you monitor your neural signals on the go.”

New Scientist Magazine issue 2830 14 Sept 2011 has an article Phone app runs portable brain activity scanner describing our Smartphone Brain Scanner.

A video of our smartphone brain scanner is available:

The CogSys activities and projects at Roskilde Festival are nicely summarized on the CogSys website.

The 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.

DTU student Thor Riisbjerg Hedegaard won the Roskilde Festival developer competition with his concept ”Roskilde Hook Up”, which includes an app allowing festival participants to “hook up” with other camps or participants.
