Our first Quantified Self Show and Tell in Amsterdam took place on September 20 at Het Volkskrantgebouw. More than sixty people showed up to attend and some even came from Germany and France! Sebastiaan ter Burg kindly provided us help with the video and photos. All the videos can be found on Vimeo and all photos on Flickr.
Concentration and meditation van be measured with electrodes. Beer van Geer gave a presentation on how he designed an application based on the Neurosky platform, a portable brain interface controllable by meditation.

















What a great meeting; wish I could have come! Your description of Peter’s spreadsheets and his predictions remind me of Extreme Programming’s “Planning Game” where developers hone their estimating skills over time. This lets them make better estimates of their productivity. QS for programmers!
James’s relationship analytics are a beautiful example of social experimenting. In my Experiment-Driven Life presentation (http://tinyurl.com/experiment-driven-life) I argue that all relationships should be experiments. This is because both people are changing every day, and stagnation is a risk. Plus, experimenting on your partner can be fun!
I’d love to hear more about Martijn’s personalstats.nl. Questions (and of course curiosity) are central to my Think, Try, Learn work, and I’m intrigued what role they play in “modules containing questions”.
Beer’s experience with Neurosky brought up some wonderful ideas for experimentation. What could you learn from wearing it all day for a week? But naturally the hard part is determining the correlation between the data and higher-level internal states.
Great stuff!
