QS Show&Tell #9 - Recap
Gary Wolf
The QS Show&Tell #9 was very fun and interesting. Here is a quick recap with links. We met at Stanford courtesy of Martha Russell of Stanford's MediaX, and the evening began with Martha's intro to her program, which links visionary research to industry applications. A list of fall seminars at MediaX shows a bit of what they are up to. The seminars are open to the public, and full of interesting things for QS types. Martha hosted as at the Wallenberg Hall Learning Theater, a great experimental learning space with high walls, three projection screens, and balcony viewing.
Steve Brown's presentation of 3banana came at a more fair and leisurely pace than at the last meeting, where he was stuck at the end of a long night of talks. Steve was the creator of Health Buddy, a pioneering self-tracking system, which he sold to Bosch Healthcare. 3banana is a more general tool, and Steve talked about his goal to augment human intelligence through giving us access to more efficient external memory. Steve's talk showed a couple of self-tracking trends we've already noted coming together, including SMS as a tracking lingua franca and structuring data with hashtags.Mark Carranza gave an update on his Social Memory Experiment, first presented at a QS last December. He is working toward taking his personal memory tracking system and releasing it as a social app, and invited all interested parties to help. More on Mark's interesting work can be read here at this earlier post: The Social Memex.
We got to meet Margie Morris, the inventor of the "mood phone" in person, as she was visiting the Bay Area. Margie's work was described in an earlier QS post: The Mood Phone and the Circumplex Model. Trained as a clinical psychologist, she is a senior researcher at Intel's Digital Health Group. She played us some excerpts from videos with users discussing possible applications. One of the users in the video, a male working in a technical field, explained to the interviewer his practice of concealing his mood in order to avoid conflict, and speculated about the usefulness of a technical system to reveal actual emotional states. This provoked some interesting discussion of the social dimension of mood tracking.
Alexandra Carmichael invited everybody to take advantage of the stellar QS Scientific Advisory Board. These are professional researchers who are willing to field questions about self-tracking and self-experiment, which Alex will collect and transmit. The questions and answers will be published here, so that others can take advantage of the advice. Experiment design, statistical analysis, or other topics are welcome. Alex published her invitation on the blog a few weeks ago, in this post: Introducing the Quantified Self Advisory Board! Take a look at it and see the excellent resources available to you.Brian Mossop, who blogs at The Decision Tree, a blog about predictive medicine and the future of healthcare, presented an idea for a new smoking cessation company, that gave smokers a decreasing "budget" of cigarettes and rewarded them with permission to smoke cigarettes (withing the budget) when they met exercise or other goals. Brain's father was a smoker, and he suspects that methods of self-tracking and simple rewards, plus some social encouragement, will be helpful to people trying to quit.
Finally, Robin Barooah showed the results of his coffee and concentration self experiment. He posted here about it already. (See: The false god of coffee.) His post was widely linked, with mentions on BoingBoing, Hacker News, and Freakonomics, and is now the most commented post on QS. Thanks Robin for a great post!
The false god of coffee
Robin Barooah
I made the same amount of coffee each day, using a vac-pot. Although I didn't measure caffeine content, I did control many factors including grind, age of beans, water temperature and water/coffee contact time. From this controlled pot of coffee, I used measuring cups to discard an additional 20ml per week. I used notebook software to keep some records of my progress and I started with a 3 cup pot in mid-April '09. Towards the end of July I wrote "I am increasingly wanting to abandon this project altogether", but I continued and on 8th August I was down to a half shot glass per day, and decided I was done.
We're back!

The posting problem that kept us offline for a few days is resolved now.Introducing The Quantified Self Advisory Board!
Alexandra Carmichael
Do you need help with your self-tracking data analysis? Is there a specific problem or burning question about your experiment design that you'd love some guidance on? Gary and I are proposing an idea to help - read on for details!We've gathered an amazing Quantified Self Scientific Advisory Board to be part of our community. It's a star group of international scientists involved in data analysis, data visualization, and self-experimentation. In alphabetical order, they are:
- Alex Bangs, Human Predictive Biosimulation, Entelos
- Gordon Bell, MyLifeBits, author of Total Recall, Microsoft Research
- Jeff Heer, Collaborative Data Visualization and Flare/Prefuse, Stanford
- Gary King, Quantitative Social Science and n=1 experiments, Harvard
- Teresa Lunt, Director of Computer Science Lab, PARC
- Seth Roberts, Self-Experimentation guru, author of Shangri-La Diet, Berkeley and Beijing
- Neil Rubens, Data Mining, University of Electro-Communications, Tokyo
The experiment we'd like to do is to encourage Quantified Self members to formulate questions about the personal data that they are trying to work with. Post them as comments or send them to me. We will make sure the questions are interesting and at least partially answerable, pass them along to the appropriate Advisor, and publish the questions and responses here on the Quantified Self blog, as a way to get discussion going and add value to everyone involved.
So let us know what you think, and start asking questions!
Self-trackers' Show and Tell Number 9
Kevin Kelly
We will have our 9th Quantified Self Bay Area Meet Up this week on Wednesday, October 14, 2009. It will be held in Stanford University at the Wallenberg Learning Center (below).
As in the past, this is a user-generated evening of presentations by folks who are self-tracking in one form or another. Each presenter gets about 12 minutes to tell everyone what they are learning and what tools they are inventing.
I was unable to attend the last show and tell because it came during the final weeks of my overdue book deadline (which is now past me!). But Gary Wolf and I will be co-hosting this one, and filming the talks. If you are around the Bay Area go over to the QS Meetup page to get directions and let us know you are coming. I heard the last meeting was swamped, so we'd like to be more prepared this time. (We WILL post the talks from last meeting.)
Taking Blood Pressure at Home - How Often?
Gary Wolf
Hypertension, 25 (2): 294 - Hypertension
I measure blood pressure at home. Unfortunately, it is easy to become bored with this procedure, and neglect it. In fact, it is more fun to wonder why measuring blood pressure is so boring than actually measuring blood pressure, so of course that's what I've been spending some of my time on lately. My guess is that part of the problem is that home blood pressure measurements vary a lot. I've had single sessions in which my systolic ranged 11 points and my diastolic 16 points. This measurement range is larger than the likely effect of any intervention I'm going to be making. Therefore, a single measurement session doesn't give me the feeling that I'm adding any information. It's frustrating and stupid. Damn measurements.
Of course a good way to track measurements with a lot of random error is to use a moving average. So here's the question: how many blood pressure measurements does it take to get results that accurate enough to discern the effects of treatment? Here is a graph from a paper published in Hypertension that suggests an answer. I won't break down the method here. There is a link to the paper at the bottom of the graph and you can explore it for yourself. The quick version is that researchers compared the difference between two series of measurements taken at home, varying the number of measurements in the series, and watched the difference decrease as the number of measurements went up. The graph shows a nice, smooth decrease in variation. You achieve 80% of the total drop in variation after 15 measurements.
In other words, if you take three measurements per day, you can get a decent baseline for blood pressure experiments in five days. This seems like good news.
Three Bits of Exciting Self-Tracking News
Alexandra Carmichael
I recently came across Mikael Huss' Follow the Data blog, which reports on data-driven trends in reality mining, self-tracking, and personalized medicine. In a recent post, Mikael talks about three bits of self-tracking news that are sure to create tingles up the spines of Quantified Self readers:1. FitBit ships
At long last! FitBit, the accelerometer with the beautiful clip-on form factor and wireless uploading of exercise and sleep data, has arrived. A one-time fee of $99 puts passive motion tracking in your pocket.
2. DailyBurn launches FoodScanner iPhone app
Tracking your fitness and nutrition is going mobile. DailyBurn has a $0.99 iPhone app that lets you take pictures of the barcodes on foods you eat, helping you more smoothly track your caloric intake.
3. Gordon Bell and Jim Gemmell release Total Recall book
Based on their experience with the MyLifeBits project at Microsoft Research, Bell and Gemmell wrote Total Recall: How The E-Memory Revolution Will Change Everything. They talk about the future implications of being able to remember everything about your life in delicious detail.
These are definitely exciting times to be a Quantified Self enthusiast!
Self-Tracking Wins at the Mayo Clinic
Alexandra Carmichael
The Mayo Clinic held their Transforming Healthcare Symposium last week in Rochester, MN. On display were the latest innovations they are brewing up in their SPARC Innovation Lab, like real-time, on-screen specialist consultation when you go to visit your primary care doctor. A stellar lineup of speakers from Intel's Craig Barrett to IDEO's Tim Brown and SPARC's passionate Maggie Breslin talked about patient empowerment, change by design, and healthcare as a conversation.There was also a competition for ideas that would change the future of healthcare. I entered this competition using self-tracking as a topic, and was one of 3 winners! Here is the 5-minute talk I got to give to 500 healthcare change agents at the Mayo Clinic, and the written summary that won the competition.

"The New Wave of Self-TrackingUbiquitous, invisible biosensors. Constant, streaming measurements. Analytics for your health.
Detailed self-tracking will transform our understanding of our bodies, our health, and our medicine. Geeks are already tracking everything from calories to blood pressure to steps taken during the day (Quantified Self). People with chronic conditions track their treatments, pain levels, and side effects (CureTogether).

The ultimate promise when this goes mainstream is true personalized medicine, where each person gets a treatment plan individual to their body. It's an exciting future, and the seeds are being planted now."
SF Bay Area QS Show&Tell #8
Gary Wolf
At this week's Bay Area QS Show&Tell we had a packed house at the Institute for the Future in Palo Alto. The recap below is powered by Mark Carranza's incredible memory experiment, described in the last post. I've used Mark's work to refresh my own memory so that I could describe what happened last week more accurately.
Attila Csordas talked about posting his 23andMe data, one SNP at a time on twitter. Attila said this was a "failed experiment" due to the limitations of the twitter service; for instance, twitter doesn't like to see lots of similar posts, and tends to interpret them as spam. But the idea of treating the genome as a person information stream, along with the notion of SMS as a common transfer protocol for data normally considered sensitive and private, were just a couple of interesting points from the discussion that followed. Another great comment: instead of making the human the account holder, what about making the SNP the account, allowing each SNP to have its own followers.Sri Srinivasan showed us his self-tracking web site, Facet of Life. With Facet of Life, you can schedule regular alerts and reminders via SMS, email, and the web. When you reply to the message with a word or a number, it is entered into a database, and Sri is building tools to aid understanding. Sri, who suffers from chronic pain, talked about some of the knowledge he had already gained from using the tool; for instance, visiting the gym reduces pain, even when the session is brief. He used to skip the gym if he wasn't going to have time for a full workout, now he goes even if he only has a few minutes.
Can estimate suicide risk by counting words? Bill Jerrold talked about the quantitative analysis of natural language. After a general introduction to the notion of forensic linguistics by way of Don Foster's work, he reviewed some recent findings that psychiatric conditions can be identified based on subtle linguistic abnormalities, and that this process can be automated using speech recognition software. His talk raised the interesting prospect of quantitative self-monitoring via recordings of everyday speech and writing. (Here are two interesting papers Bill mentioned: "Word Use in the Poetry of Suicidal and Nonsuicidal Poets" and "Language use of depressed and depression-vulnerable college students.")
Esther Dyson described her own use of the 23andMe personal genotyping service. Giving us a quick tour of her own genome, she mentioned that she especially appreciates looking at the graphs that compare the genotype of various members of her family. She said the immediate practical benefit of the personal genome was - for the moment at least - very slight and that people who are using the service at this point are playing a role as benefactors, contributing to a critical mass of data that can lead to new discoveries.
Joe Betts-Lacroix revisited "Joe's Dream," his vision an easy method of entering and retrieving personal data. Since he gave this talk, barely a year ago, several features of this dream have been realized. So he proposed another step that he called "personal instantaneous feedback." (The video above is Joe''s original talk last year, at QS Show&Tell #2.)
Bo Adler works at Fujitsu labs, where his work involves collecting and processing medical sensor data. Bo is also a walking experiment. He showed us how he does constant monitoring of his heart rate, blood oxygenation level, and blood pressure, using wearable sensors, and then showed us the results of one of his self-experiments. He suffers from sleep apnea, and uses a variety of methods to combat it. By graphing his biometrics during sleep, he learned - among other things - that while taking Nyquil made him feel that he was sleeping better, his data told a different story.Mark Carranza gave us a quick recap of his MX "memory experiment," which he described more fully at QS Show&Tell #3.
Finally, Steve Brown gave a too-quick talk about "augmenting your brain," and about 3banana, a system he's created for enhancing working memory. We were out of time, so he is going to come back again. If you can't wait, however, the slides are here.
