TEDx Talk: Human Data for Life

My TEDx talk entitled Human Data for Life from the recent TEDxCopenhagenSalon event is available.

Over the last couple of years self-tracking has gained increased interest with the availability of smartphones and low-cost wearable sensors. The increasing quantities of data that we can capture about human behavior and interactions are key to future improvements in health and well-being.

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.

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.


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.
