Dr. Kevin Patrick is the director of the Center for Wireless and Population Health Systems at Calit2. At the 2015 Quantified Self Public Health Symposium Kevin offered novel ways to think about the social utility of data. “The petabytes of data that are coalescing outside of traditional medical care and public health are a new natural resource,” he said. But instead of using the trite and troubling metaphor “data is the new oil,” he asked us to turn our attention in a different direction, to the notion of thinking about data as part of our commons. “Properly cared for and curated, it can benefit all of us, like clean air and clean water.”
Kevin is leading a growing network of researchers and companies called the Health Data Exploration Project, whose members are committed specifically to using self-collected data for public health discoveries.
“When I see someone driving towards me with their face buried in their phone, I get gloriously indignant about it.”
Robby Macdonell has given great talks on transportation logging and time-tracking. Here, he combined those two data streams, using Automatic and RescueTime, to prove that he does not use his phone while driving nearly as often as other drivers.
Only the data didn’t agree.
Watch how Robby confronts the realization that he is more distracted than he thought and the changes he made because of it.
From the Quantified Self Public Health Symposium.
Larry Smarr’s major contributions to scientific progress are well known. A physicist and the founding director of the National Center for Supercomputing Applications (NCSA), he helped bring the power of computing to scientific research at a time when computers will still highly specialized instruments. Today he is the Director of the California Institute for Telecommunications and Information Technology (Calit2), one of the most innovative research institutes in the world.
He’s also an avid self-tracker, using his own data to correctly self-diagnose the onset of Crohn’s disease. At the 2015 Quantified Self Public Health Symposium, Larry spontaneously launched the meeting with a description of what it was like to be at NCSA in the early 90’s when his student Mark Andreessen, the creator of the first popular Web browser, could review every new website in the world by hand. “We could keep up with that little bit of the exponential.” Larry asked us to consider that a similar experience of scaling lies ahead of us in the Quantified Self movement. What happens at the birth of new technologies and new fields of knowledge, when very early participants get to know each other and reflect together on what values and uses will be encoded in our tools, can influence developments that affect hundreds of millions of people.
The DIY Scientist, the Olympian, and the Mutated Gene by David Epstein. There are several surprising twists in this story of a non-professional scientist named Jill Viles, who made an important discovery about her own rare genetic disorder. What inspired me mostwas Viles’ tenacious reliance on her own capacity to reason, even in the face of skepticism from professionals who had less knowledge (though more confidence) than she did. Eventually, she connects with highly technical scientists whose research direction she influences with her ideas. Epstein got a fantasic quote from one of them when he asked the scientist if this has ever happened before. “In my life, no,” he says. “People from outside coming and giving me hope? New ideas? I have no other example of this kind of thing. You know, maybe it happens once in a scientific life.” I found myself wondering if this kind of thing will be less rare in the future. -Gary
A Drug to Cure Fear by Richard A. Friedman. This article intersects two of my interests that stem from my own self-experimentation. From my stress tracking I realized that many of my reactions in my day-to-day life are influenced by traumatic memories. From my spaced repetition practice I learned how memories can change over time through retrieval and consolidation. A study done in the Netherlands suggests that a memory can be decoupled from an associated fear response by using propranolol which blocks the effects of norepinephrine, a chemical that strengthens connections in the brain. The study has yet to be replicated, but hopefully it will increase our understanding of trauma. -Steven
Internet of Things security is so bad, there’s a search engine for sleeping kids by J.M. Porup. Ever since doing a research project on data flows for our first Quantified Self symposium we’ve had what you might describe as a below average level of confidence in the security and reliability of information traveling outside the immediate context of its collection, now that APIs connect to APIs connecting to yet other APIs. Still, even I was surprised by the recklessness and potential harm described in J.M. Porup’s brief account of a search engine that displays random pictures from internet connected consumer cameras around the world. -Gary
Algae bloom toxin linked to Alzheimer’s, other diseases by Amy Kraft. One consequence of the climate change and the depletion of fish stocks in ocean’s is the increase occurrence of algae blooms. Ethnobotanists found a correlation between algal blooms and neurodegenerative diseases among remote populations in the Pacific. New research suggests that cyanobacteria, the microorganism in these blooms, has a neurotoxin that can cause neurodegenerative precursors that develop. This neurotoxin enters the human food chain as it bioaccumulates in fish and shellfish. -Steven
Glass Half Full Succeeds in Unwinding Upsets by Paul LaFontaine. Most people have moments of irritation or worry throughout the day. Paul wanted to find out what worked better as a response to these moments. Option A was to step back and observe his emotions in a manner similar to that taught by some schools of meditation. Option B was to figure out the source of irritation or concern and think of a positive angle to the situation. What is great about this post is the very simple but illuminating experiment that he devised to explore this question. -Steven
Finding My Optimum Reading Speed by Kyrill Potapov
As an English teacher Kyrill Potapov spends a lot of time working with 12 year old kids who are trying to improve their reading, writing, comprehension, and analytical skills. In this talk, he explores a remarkable method of speed reading, called Spritz, that promises to let you “read Harry Potter in three hours” with full understanding and recall. Could such a promise possibly be true? -Gary
Heart Rate Variability, Body Metrics, and Cognitive Function by Justin Lawler. This is a great examination of how Justin’s HRV measurements correlate to all other personal data he has collected. -Steven
Using Spectrograms to Visualize Heart Rate Variability by Randy Sargent
Randy’s idea about using spectrograms, normally used for audio signals, to create a portrait of your own time series data, is completely novel as far as I know. -Gary
Spurious Correlations by Tyler Vigen. An entertaining collection of unrelated facts that can be correlated with a high degree of confidence. -Steven
Hackers Diet, FIRECalc and weight loss by u/Thebut_. This chart is a mess, but the idea behind it is fascinating. This reddit user was inspired by FIRECalc, a financial tool that “projects your future assets based on historical market data” and tried to apply it to his weight data. Instead of giving a single projection, the tool shows a range of possibilities. This is similar to how Baseball Prospectus’s PECOTA system uses a weighted range of possibilities (probability distribution) rather than a single guess (point estimate) for forecasting a prospect’s future performance. I would like to see more of this kind of thinking applied to personal data. -Steven
Darwin Tunes by Bob MacCallum, Armand Leroi, Matthias Mauch, Steve Welburn, and Carl Bussey. A fascinating project that treats pieces of music like organisms that can mate and reproduce based on listeners’ votes. These audio loops started off as random noise, but as the generations moved into the thousands, the presence of chords and higher order melodies emerged. At this point, there have been over 8700 generations. You can take part yourself! -Steven
In this fascinating talk Rocio Chongtay shares her novel and thoughtfully designed experiments in using music to adjust her concentration and relaxation depending on what she’s doing. Using a consumer EEG device from Neurosky, Rocio tried different types of music while tracking the relaxation and concentration dimensions identified by the Neurosky algorithm. She had experience experimenting with Neurosky in her lab, and then turned these techniques on understanding something about her own mind.
Many participants in Quantified Self meetings around the world are involved improving public health as researchers, policymakers, clinicians, and community leaders. Once a year, we convene a Quantified Self Public Health Symposium to explore how we can better support new discoveries about ourselves and our communities. With the next meeting coming up in May, we thought we’d link to some of the materials from the 2015 Quantified Self Public Health Symposium, which we’ve posted in the QS Public Health channel on Medium.
This meeting is by invitation only, but it is not hard to get an invite: If you are working on public health research or have another kind of contribution to make to this discussion, please take a look at the Quantified Self Public Health Symposium website and be in touch if you’d like to come.
“My name is Lane Desborough, and I’m going to spend the couple of minutes talking with you about Nightscout on behalf of the many collaborators who have been part of this ongoing program. But first I want to introduce you to my son, Haydon. He just got a new quadcopter and he has hacked it to turn it into a bomber so he can drop water balloons on his younger brother. He’s a happy, healthy fifteen year old. But that wasn’t always the case. Five years ago Haydon was diagnosed with type 1 diabetes, and our family’s life took a radical right hand turn…”
Nightscout, which Lane describes in this wonderful talk, allows people with people with diabetes and parents of kids with diabetes the see real time data from a blood glucose monitor on a mobile device. While similar efforts are underway among manufacturers, leadership is coming from patients and caregivers.
The quality and commitment here can inspire anybody who is thinking about how QS tools fit into new forms of knowledge and cooperation. The projects Lane discusses in this talk have continued to grow and evolve. Supported by a remarkable group of activists and a technically expert community made up mainly of people with diabetes and parents of kids with diabetes, contributors to these projects have created a suite of tools that can dramatically improve self-care.
For instance, a couple of weeks ago I saw this tweet from Howard Look, founder of Tidepool:
Did you know that people with diabetes have been building their own artificial pancreas systems? Read more about Nightscout, the Open Artificial Pancreas System, and related projects at these links:
As an English teacher Kyrill Potapov spends a lot of time working with 12 year old kids who are trying to improve their reading, writing, comprehension, and analytical skills. In this talk, he explores a remarkable method of speed reading, called Spritz, that promises to let you “read Harry Potter in three hours” with full understanding and recall. Could such a promise possibly be true? And, if the claim is true, another question arises. Is such a pace desirable and useful, or rather something quite alien to the activity of reading?
With his students, Kyrill decided to resolve these questions empirically, reading the same material in a book, on a screen using conventional scrolling, and on a screen using the novel method of Spritz, which displays words one at a time at a pace determined by the reader. They found high comprehension at the high speeds permitted by Spritz, but with some cost, which he outlines in this wonderfully clear and interesting talk.
Kouris Kalligas, a long time participant and contributor at Quantified Self meetings, is the creator of the very easy to use data aggregation service AddApp. AddApp is an iPhone app that makes it simple to gain insights from data gathered on dozens of different devices. While running his startup, Kouris has also been doing ongoing self-tracking experiments. At QS Europe 2014, he gave a excellent show&tell talk about his sleep, diet, and exercise data. In the talk below, he discusses using mood data in combination with calendar data to reflect on the relationship between emotion, experience, and self-image.
It’s been an honor to have Beeminder founders Daniel Reeves and Bethany Soule participating in Quantified Self meetings, giving us a chance to watch the evolution of their very useful tool for setting and achieving personal goals. These days they are working on the forefront of device and service integration. In this talk Daniel gives a brief explanation of how to bring data into Beeminder with minimal hassle.
(Note Daniel’s generous shout-out to another great QS toolmaker, Rescue Time.)
