Stefano Schiavon is an assistant professor and researcher interested in sustainable building design. As he told us at last month’s Quantified Self meetup in Berkeley, California, “I am Italian. I love architecture. And I think buildings are beautiful.”
One goal of building design is to increase individual comfort. However, this poses a problem. Everyone is different. For instance, what should the temperature be set at? There is no one temperature that is comfortable for everyone. It doesn’t work to try find a temperature that is pleasant to the largest number of people. As Stefano puts it, it is like going around and measuring everyone’s foot to get an average, say 9, and then dictating that everyone wear size 9 shoes to the office.
So how does this connect with Quantified Self? Stefano and his colleagues have embarked on a series of studies to better understand people’s individual preferences for their environments and they are doing it with QS tools. The first study was fairly simple. They tracked the ambient temperature and air quality of the person’s surroundings and used an app for feedback on whether the environment was “acceptable” or not. Carbon dioxide and temperature measurements were taken throughout the day, while the person was in the car, at work, the restaurant, etc.
Stefano and his colleagues noticed a couple things. One is that there was higher exposure to CO2 in air conditioned rooms as opposed to naturally ventilated rooms. While Stefano says that this CO2 level is not a concern in of itself, it correlates with other pollutants, such as, airborne transmitted diseases (e.g., influenza).
Despite these data, Stefano and his colleagues found that just recording the environment gave him a limited ability to predict a person’s comfort. He is hoping, and the focus of his next study, is that by getting a person’s QS data (heart rate and body temperature), this predication ability will improve, making it easier to personalize a space’s comfort for each individual.
For Stefano, all of this is in support of a larger cause, climate change. He was saddened to discover that nearly 40% of greenhouse emissions come from buildings. He hopes that by building better models for personal comfort by using QS tools, he can help people enjoy their environments more, while minimizing the environmental impact.
You can see the entire video of his talk at his QS project page.
Here are links to some of Stefano’s papers:
- Occupant satisfaction in LEED and non-LEED certified buildings
- Quantitative relationships between occupant satisfaction and satisfaction aspects of indoor environmental quality and building design
- Real-Time Monitoring of Personal Exposures to Carbon Dioxide

How do you describe Oura?
Ōura makes a self-tracking ring that helps you be your best in everyday life. By sensing your body’s physiological responses, it guides you to adjust sleeping behavior and activity level to improve your sleep quality and optimize mental and physical performance. We want to help people stay balanced, improve quality of life and overall mental and physical performance.
What’s the backstory? How did you get started?
Our passion comes from our own need to stay balanced and performing well in the middle of hectic business and family life and our desire to provide the same opportunity for others so that people can live up to true their potential.
Several members of our team have created consumer products, either medical, wellness, sports and/or mobile and/or embedded systems in different contexts. A few of us have done research and created algorithms, one for more than 17 years at Polar, the leading manufacturer of heart rate monitors. Several members of our team have monitored themselves for a long time in different ways. We knew that to get a long-term view on physiological changes in the body we had to find a unique way to access the data with high accuracy but in a very desirable comfortable design. We found the finger to be an optimum place for measurement and through years of extensive R&D and prototyping, eventually managed to fit a full featured computer into a small enough form. The ŌURA ring was born.
What impact has it had? What have you heard from users?
The ŌURA ring will be available for pre-orders in July-August, so extensive feedback from users/customers is yet to come. However, within a limited group of people and our own team, we have been using ŌURA rings – some of us wearing two of them continuously – for more than half a year. And with the earlier prototypes, we’ve collected data for much longer.
Since launching the product at Launch Festival in San Francisco in March 2015, we have met hundreds of people, showing them the ring and the App and sharing the science and technology. The feedback has been very positive. People love the design and especially appreciate our focus on providing the user with an understanding of how to improve sleep quality, adjust activity, and balance them to optimize their mental and physical performance.
What makes it different, sets it apart?
ŌURA ring amplifies the voice of the body. Through the App it gives an opportunity to better understand what choices are good for us. Since our lifestyles are unique and the physiological reactions of our bodies are unique, by listening to our own bodies we can adjust our behavior to stay balanced and perform well.
ŌURA ring is simple and effortless to use. There are no buttons or lights, it requires nothing from you. It just senses your body and its reactions when you wear it. It combines style and comfort with high-end technology, applying over three decades of research on human physiology and behavior.
What are you doing next? How do you see it evolving?
Over the few months, we are creating connections – our target audience and especially early adaptors – mostly in the USA, to deepen our understanding of how we can refine the benefits of using the ŌURA ring in every day life.
ŌURA will be evolving in many ways, based on the feedback and ideas coming from the backers of the early adaptors in the pre-order campaign as well as from those partnering with us to develop their own solutions and applications based on ŌURA ring.

How accurate is the Apple Watch’s step counter and distance tracking? by Dan Graziano. Great article testing how accurate the new Apple Watch is versus other activity trackers and smart watches. It’s a short(ish) controlled experiment, but the initial results seem positive. Key takeaway: if you have an Apple Watch take the time to calibrate it!
Forget the Fitbit: Can Wearables be Designed for the Developing World? by Jessica Leber. Together with Frog and ARM, UNICEF is launching a “Wearables For Good” challenge to generate ideas and designs for new sensors and technologies that can be used in “resource constrained environments.” Check out the challenge website here: Wearables For Good.
Is the Wearable Health Movement Sustainable by Tim Bajarin. TL;DR: Yes.
With Great Data Comes Great Responsibility by Paz. Ownership, privacy, and longevity. These are the three topics taken on in this long, but well written article on data. If you’re working with or collecting a user’s data this is a must read. And if you’re sending your data to a service, you might as well read it too.
Data is Personal by Frances Angulo. A beautiful post by Frances about using a few simple tools to track anxiety, including a few wonderful visualizations. Once again, I’m astounding by the simple power of using a tool like Google Forms to ask oneself the question that matter.

Data (v.) by Jer Thorp. So many people in my network were sharing this over the last few days I had to give it a read, and I’m happy I did. Jer Thorp makes a succinct argument for turning the word “data” from a amorphous blob of a noun into a verb.
By embracing the new verbal form of data, we might better understand its potential for action, and in turn move beyond our own prescribed role as the objects in data sentences.
How Not to Drown in Numbers by Alex Peysakhovich and Seth Stephens-Davidowitz. In this great article, two data scientists make the case for “small data” – the surveys and rich contextual information from open-ended questions.
We are optimists about the potential of data to improve human lives. But the world is incredibly complicated. No one data set, no matter how big, is going to tell us exactly what we need. The new mountains of blunt data sets make human creativity, judgment, intuition and expertise more valuable, not less.
Data, Data, Everywhere, but Who Gets to Interpret It? by Dawn Nafus. We’ve been collaborating with Dawn and her team at Intel for quite a while, and we’ve learned a lot. Reading this wonderful piece lead to even more learning. Dawn uses this article to describe not only the community of individuals who track, but also why, and what happens when it comes time to interpret the data. (You can explore DataSense, the tool Dawn and her team have been working on, here: makesenseofdata.com)
Applying Design Thinking to Protect Research Subjects by Lori Melichar. Lori is a director at the Robert Wood Johnson Foundation and recently did some work related to how institutional review boards (IRBs) function. For those who don’t know, IRBs are the groups/committee that evaluate the benefits and harms of human subjects research. Their process hasn’t changed much in the few decades, but the face of research has. In this short post Lori describes the ideas that came from thinking about how we might re-design the current system.
ResearchKit and the Changing Face of Human Subjects Protections by Avery Avrakotos. As mentioned above, research is changing, and one of the big changes we’re currently seeing is the use of mobile systems like Apple’s ResearchKit. It’s not all sunshine and roses though, the popularity and excitement that goes along with these new methods also means we have to think hard about we protect those who choose to participate.
I measured my brain waves and task performance on caffeine- here’s what I found by John Fawkes. John was interested in how much caffeine he should be ingesting to help with his mental and physical performance. In this post he details some of what did, how he tested himself, and what he learned about how caffeine, and how much of it, affects different aspects of his life.
The Quantified Self & Diabetes by Tom Higham. Tom was diagnosed with diabetes in the late 80s. In this short post he details some of the different apps and tools he uses to “get my HbA1c down to the best levels it’s ever been.”
2014: A Year in New Music by Eric Boam. I had the pleasure of meeting Eric recently in Austin and was blown away by his ongoing music tracking project. I’m excited to see this new report and learn a bit more about what he’s discovered.
Apple Watch Heart Rate Comparison by Brad Larson. Brad used a simple script to export the heart rate values from his Apple Watch and compare it to two different heart rate measurement devices. Above is a comparison with the Mio Alpha, and he also compared is to a more traditional chest strap and found the readings to be “nearly identical.”

Gordon Bell has been involved with self-tracking for over a decade. From his ground-breakign MyLifeBits project to his popular book on the possibilities of a fully digital life he is constantly thinking about new ways we can understand ourselves through the data we collect. We are always excited to see him at our QS events and were especially happy to have him reach out to us about presenting at our last Bay Area QS meetup.
Gordon has experienced two heart attacks, one in 1983 and another in 1996, two double bypasses, and currently is living with his third pacemaker. It probably isn’t surprising given his medical history that he has a keen interest in understanding his heart. In this talk Gordon describes what he’s been learning from the data collected from his pacemaker and the 320 days of heart rate and activity data he has collected with his Basis watch.
We’re also excited to have Gordon joining us at our upcoming QS15 Conference & Activate Expo. Register here!

The folks over at Mapbox aren’t just satisfied with making gorgeous maps though. In this post, Eric, a data artist and software developer at Mapbox dives into the data to see what questions he can answer.
General Wellness: Policy for Low Risk Devices – Draft Guidance for Industry and Food and Drug Administration Staff . On Friday, January 16, 2015, the Food and Drug Administration released a draft of their current approach to regulating “low risk products that promote a healthy lifestyle.” These guidelines point to a stance that will allow many of the typical self-tracking tools currently in use today to remain outside the regulations normally associated with medical devices. (A quick overview of this document is also available from our friends at MobiHealthNews)

In response to the much anticipated reveal of the Apple Watch I did a bit of digging around to find out where we stand with wrist-worn wearable devices. I found over 60 different devices. The following list focuses on self-tracking tools, I intentionally left out those that work only as notification centers or secondary displays for your phone. I’m sure this isn’t all of them, but it’s as good a place to start as any. If you’re using one of these devices to learn something about yourself, or you’re just interested in these type of wearable tools we invite you to join us in San Francisco on June 18-20, 2015, for our QS15 Conference & Exposition.
(Thank you to all those who commented here, on Twitter, and on our Facebook group pointing us to additional devices to add!)

Kiel Gilleade has been interested in measuring and visualizing physiological data for quite a while. In 2011, he presented his BodyBlogger project at the 2011 QS Europe Conference. In that talk he described what he learned from tracking and exploring a year of continuous heart rate data. This year, at the 2014 QS Europe Conference, Kiel returned to talk about a new project, Rhythmanalysis. Rhythmanalysis was a project centered on “visualising the biological rhythms of employees at different workplaces.” In this short talk, Kiel describes his experience working on this project and some of the lessons he learned along the way.
If you’re interested in learning more about this work I highly suggest you visit Kiel’s website where he has additional videos of visualizations he’s been working on that use data collected as part of this project.
