Sensors & Related Tools

OpenBCI + cEEGrids

By integrating cEEGrid around-the-ear EEG electrode arrays into the OpenBCI platform, comfortable and wearable long-time EEG recordings are enabled for a much more affordable price than previously possible...

Flexible EEG Cap Cable Holders

Arrange your loose EEG cap cables with these 3D-printable components. You'd better do it to minimize mechanical recording artefacts...


Flow

Flow & The Heart

Initially, I set out to learn and improve the understanding of what goes on in the peripheral nervous system during the flow experience. From this, a vivid discussion emerged on how observations of heart rate variability can inform on the interplay of the two autonomous nervous system branches during flow...

Flow & The Brain

Afterwards, I became increasingly intrigued with the brains configuration during the flow experience. In the literature two main theories revolve around flow as a state of transient hypofrontality or a state of synchronization of attention and reward networks - two propositions the EEG can provide evidence for...

Flow & Machine Learning

To enable the development of adaptive systems that are able to foster flow experiences, we have started to explore the possibilities of classifying the state occurence using machine learning methods. So far, Random Forest classifiers provide the best results using ECG and EEG data...


Biofeedback

Bio-Work

In this project, I implemented various types of sensor and biofeedback instances, to provide information on self-regulation of physiological activation and stress (as indicated of heart rate variability changes) during work. The version shown here is one that uses an ECG chest belt and the Philips Hue color-changeable lamps...

Bio-Wolf

In this project, I adapted the popular card game Werewolf (Witches of Salem for some) to be used with Live Heart Rate Biofeedback from all players. By observing the HR traces of all players after a "night" of the werewolf going around town one can ask the question: Who is exposed by the excitement of keeping a secret?...

Team Biofeedback

Recent research states that there is something like a team IQ - and apparently it is linked more strongly to team members abilities of recognizing others' emotions than it is to individual IQ. Therefore, we considered whether or not team interaction could not be improved by enriching digital interactions with internal state information (here: changes in team members' heart rates)...


Other

Neuro-Cookies

Do you like brains and cookies? Well, I do! To unite both passions I made these puzzle-like brain cookie cutters. It's like alphabet soup, just with brains and cookies...

Three Graces Web-App

I learned in a TED Talk that we apparently get the formula wrong: You are much more likely to be successful in what you do when you take care of your wellbeing or happiness first, not the other way around...

Tea Timer App

Ok, here i just wanted to learn some Python and GUI design. As I was acquiring an interest for tea at the time, I decided to program a simple, but nice-looking tea timer app...
