Tobias Zimmer tracked what he ate and, in particular, what he didn’t eat. The image above comes from a series of ceramic plates that were created using generated graphics based on the crumbs he left. For more, see his Tumblr: Food-Data:
»Food Data« elevates an everyday occurrence to the realms of art. Minimalistic crumb compositions that emerge while eating every day, are enhanced by generated graphics, which refer to the topic of computerized data tracking of human behavior. The final plates encourage to contemplate on everyday life and to find beauty in daily routines, but at the same time remind of technological advancement and practices of (self-)surveillance, that doesn‘t even stop before the private ritual of eating.
Haunted By Data by Maciej Cegłowski. A keen sense of how things can go wrong is needed if we are to have any hope of – well, if we are to have any hope! This essay by Maciej Ceglowski about the highly toxic nature of large scale data aggregation is highly recommended.
How Your Device Knows Your Life through Images by Graham Templeton. This research demonstrating that an artificial neural network was able to train itself to correctly identify 83% of the time the activity that a person was engaged, just based on the images collected from that person’s lifelogging camera is especially interesting in light of Ceglowski’s talk.
Life Stress by Marco Altini. Marco reviews an exhilarating but stressful 15 months of his life through the lens of heart rate variability.
Body Metrics Under Stress by Justin Lawler. Another stress-related piece. Justin shows through data how his body responded to the stress of giving a talk about his lifelogging experiences at QSEU15.
Pathways Project by Mimi Onuoha. This project looked at what story could be told from a month’s worth of mobile phone data from four groups of people, each with a different type of relationship: co-workers, a couple, a family, and roommates. The charts are interactive and fascinating. As Onuoha writes:
…data visualizations add a level of abstraction over real world events; they gather the messiness of human life and render it in objective simplicity. In life, goodbyes can be heartbreaking affairs, painful for all involved. But on a map, a goodbye is as simple as one dot moving out of view.
The project’s data is available in this Github repository.
My Hamster’s Activity Index by /u/snootsboots
This reddit user used a motion sensor connected to a raspberry pi to make sure that his hamster is ok when he’s away. Here’s a picture of the hamster, if you’re curious. His name is Timmy
My internet’s median ping over time by /u/asecretsin. This a very simple chart, and a simple idea. What I like about it though is that it illustrates how just a little bit of logging and data visualization can reveal a pattern in one’s environment. It clearly shows that the response times slow down from 6pm to 10pm. I have a home office and it often felt like the internet slowed down around the time people starting getting off work.

As someone who still is not satisfied with any sleep tracking device or app that I have tried, I related to this dialogue from a tumblr called Zen.Sen.Life:
- Sleep Tracking App: I see you’re not violently throwing yourself around your bed, you must be in a deep sleep. Sweet dreams, buddy!
- Me: I’m actually still awake.
- Sleep Tracking App: But you’re lying still…
- Me: Because I’m trying to get to sleep.
- Sleep Tracking App: You mean you ARE asleep.
- Me: I really don’t.
- Sleep Tracking App: You’re going to have to trust me, I do this professionally and I know sleep when I see it, and I’m pretty sure you’re asleep right now.
- Me: I couldn’t be more awake.
- Sleep Tracking App: This is all a dream…

Today’s guest post comes to us from our longtime friend and QS community member, Paul LaFontaine. Paul will be joining us at the QS15 Conference & Expo to share his expertise on tracking and making sense of heart rate variability. Read below, and then join us on June 18th through the 20th for three amazing days of talks, sessions, and meeting amazing innovators like Paul.
And when you got that look your brain just froze? You could not think of what to say? The start point for my work in Quantified Self was to try and understand that “freeze” phenomenon and how to train myself to experience it less. I negotiate a lot for business and my hypothesis was that control of physiological reactions in meetings could make me a more effective negotiator.
I had an excellent opportunity to see how I was doing this week as I briefed not one, but SIX Big Bosses. Nine people total were in the room. One Boss had showed up uninvited because he opposed the concepts being discussed. And to make matters even more fun, I was told I was the primary presenter thirty minutes before the meeting. After hearing that I thought, “This will be a great HRV reading.”
The meeting was on a controversial topic and several of the Big Bosses did not agree on how to resolve it. I had been asked a few weeks earlier to help create a resolution. We were scheduled for an hour. There were two points in meeting I remember feeling the “brain freeze” moment and had to push on by looking at the slide and restarting my mental engine. Because of the late notice that I was the presenter I could not use my standard practice of memorizing the material prior to a high intensity presentation. Here is my reading for the session:
This reading recalls the shape of the meeting very well. At the start each of Big Bosses tried to steer the meeting toward a resolution they thought was best. Big Bosses can’t help it, they get paid to steer. The Biggest Boss kept coming back to “let’s let him go through the material.” The dark blue from interval 426 to 2996 was me trying to get a word in edgewise.
In the middle of the meeting I had made my points and the Big Bosses began debating the merits of the resolution. As the spotlight moved from me I did deep breathing, listened and took notes. My memory of that period was that my brain was turned back on and I could feel a lighter feeling in my chest and head. The reading shows that I dropped from Fight/Flight as indicated by the white spaces from interval 2996 to around 6000.
Then the Biggest Boss said something to the effect that the resolution I had presented was incomplete. You can see around interval 6000 I go back into Fight/Flight as I was trying to explain how the missing part he was concerned with actually was completed. This lasted for a good period because other Big Bosses saw this as an opportunity to re-introduce their specific personal points and we were off and running. It was in this period I recall a specific “freeze” moment regarding a question on a detail that I resolved by having the group look at a different slide.
Finally I was able to get the Big Bosses to turn to the last slide where there was a collective “Oh, here it is” and you can see around interval 8900 my physiology begins to relax. The part of the resolution they were looking for was there. To my recollection the room relaxed as well. Some jokes where shared and people began to prepare to summarize and end the meeting.
During this hour long meeting I was in Fight/Flight 46% of the time, a full 27 minutes. I can’t reveal any details of the meeting, but I can believe that quality of my answers was more reactive and less thought out during those two periods. My personal variability training did make an important contribution as I was able to break up the 27 minutes into two periods that each had a specific topic I was “fighting” to make. In the first period I was concentrating on getting my main points across. Once done I was able to use my breathing and get myself to a relaxed state where I had ticked the box of “points made.” When the second period started I was only “fighting” to show the one completion point. I believe that if I had not allowed myself a completion state in the middle I would not have been as focussed on a single point which I was able to make in the end.
To see how much the environment like a meeting can change very rapidly, I had the opportunity to measure a meeting immediately after the meeting recorded above. As in I walked from the conference room for that meeting to the office for the meeting in a period of five minutes. I already had the kit ready so I just hit “record” for the second meeting.
In this second meeting I was brainstorming with a colleague on how to handle a problem that would play out over several months. There was no urgency, the colleague and I get on well and we were coming up with good ideas. Here is the reading:
That means I came from a pretty intense Big Boss meeting where there was a lot of Fight/Flight, did a BreatheSync session for two minutes and entered the second meeting. In this one there was very little Fight/Flight at all and it was a very productive 35 minutes.
Breathing tools, understanding how the physiology reacts when meeting with the Big Bosses and finding the balance between Fight/Flight and relaxation can improve both how you prepare, and how you ramp yourself down when in an intense situation. And these same tools allow a fast transition to a new environment where you can be productive as appropriate for the situation.
I will be presenting more about how I use heart rate variability at the Quantifed Self Conference and Expo in San Francisco June 18 – 20. I look forward to it and I look forward to meeting many of you there.
Paul LaFontaine is on an incredible journey to understand himself, his stress, and how he works through consistent examination of his heart rate variability (HRV). We’ve featured a few of his talks here on the Quantified Self website, and we were happy to have him present at a Bay Area QS meetup this past December. In this talk, Paul describes how he experimented with cognitive testing and recording his HRV to better understand if he was in a Flow state, and how to attain that balance between challenge and skill. Some very interesting personal conclusions about the role of belief in one’s own abilities versus actual skills.
How many times during the course of the day do you find your mental state drifting into negativity, feeling like you’re lost, or just plain stressed? How could you even keep track of this, and why would you want to?
What Did Paul Do?
Paul LaFontaine has been tracking what he calls “upsets” to better understand himself, the way he works, and to see if he can improve his mental and physiological response and recovery.
Upsets are something physiological that were happening beneath the surface, and they’re trackable. It didn’t have to be emotional, but there had to be a signal. This project is part of an longer ongoing study. Before this current iteration I manually logged over 3,000 upsets and what I found is that most of my upsets were self-induced. I’d be in a calm environment, but then become upset about something. I wanted to use technology because I was afraid of bias and I know I was missing some upsets.
How Did He Do It?
I used the HeartMath EMWave2 that measures heart rate variability and indicates when you’re in and out of coherence. When I was out of coherence I captured that as an upset. I would stop what I was doing and use an audio recorder to keep track of the time, how long I was upset, the reason, and what method I used to recover. I tracked 71 sessions (each session was 25-45 minutes) totaling 42 hours of tracking time. I logged 1292 upsets during this period.
What Did He Learn?
Paul analyzed his data and found some very interesting insights about his upsets, his reasons for being upset, and the effectiveness of his recovery techniques.
I found that I was triggering an upset every 2 minutes. My wife said something must be wrong with me, but this stayed relatively constant through the tracking period. I started to think of it like skiing a mogul course. The moguls didn’t move, it was about how effective I could move through them. And, dealing with upsets is like playing whack-a-mole. They come fast and furious and every second counts.
For recovery I was able to find that my most effective technique was breathing. By returning to six breaths per minute routine I was able to improve recovery time from 33 seconds to 17.8 seconds. It was the primary way I could remove myself from being upset and make myself calmer.
We want to thank Paul for presenting this great QS project at the Bay Area QS Meetup group. Make sure to watch the full talk below to learn more about Paul’s methods and findings, then hop over to his website where you can read about how he tracked his stress during this talk.
