Predictive modeling – an interview with Datarella CEO Joerg Blumtritt

Most of the time, we at Datarella deal with the very near future: what will be the most likely thing that individuals want or what they are up to next? We use mathematical models to predict human behavior. But not only human behavior is what Datarella is interested in. Research papers, internal customer data and external data are being used by Datarella to predict probabilities of success of specific products. We detecs patterns, weaknesses and events in behavior and product design and – together with our customers – we define workarounds, optimizations or completely new data-driven products.

Max, could you introduce yourself and tell us why you are here at the Quantified Self conference? Max First, I’m personally interested in Quantified Self: I want to know what’s new and how everything is evolving. Then, I held a presentation about a self-experiment about testosterone. And last but not least, I have presented my own startup biotrackr in an office hour. DR A self-experiment on testosterone – that sounds pretty interesting. Can you tell us more about that? Max It all started last year during some sort of a winter depression, when my blood test a relatively low level of testosterone. Since then I’ve tried to enhance this level by changing my nutrition and some aspects of my lifestyle, and I’ve presented the results here at the conference yesterday. DR What are the results? Max The results show that nutrition, sleep and stress have a big impact on the hormone balance, and especially on the testosterone level. Those three […]

I work as a Software Engineer at Narrative, a software and hardware company which makes a very tiny mobile camera that takes photos of everything you see. Photos are taken every 30 seconds, then they’re aggregated and we show you a meaningful representation of your data life. DR You’re wearing a narrative camera. Could you show it to us and explain what this camera does in comparison with a typical camera? Dan Yes. Here it is. It’s working automatically – so you wear it at your shirt or jacket, and it takes photos every 30 seconds. If you want to turn it off, you just put it into your pocket. Then we offer a service, which is connected with the camera: it aggregates all photos and tries to find the best ones by grouping together similar photos. So at the end, you have a diary of your life. DR What is the […]

Datarella People – Klaus Bscheid, Wearable Tech Entrepreneur

Here’s the transcript of this Datarella (DR) interview with Klaus Bscheid: DR Klaus, can you tell us a little bit about ambiotex Klaus Sure! ambiotex has developed a textile with integrated sensors. With these sensors we can track a genuine one-lead ECG. Based on that ECG we can extrapolate not only the pulse rate but a heart rate variability (HRV). At the same time we quantify the user’s breathing rate as well as her breathing volume. Based on the analysis of the combination of these data we can draw many very interesting conclusions. In particular, we think that HRV analysis is useful for the regeneration of the human body, for insights into coping with stress, etc. DR Our textile is an undershirt, since it should be the very first layer being directly on your skin. You can wear this shirt during your sports activities as well as in your everyday life. So what do we do with all this body data? If it’s a sportsman, we can tell him his regeneration level, i.e. we can tell him whether it makes sense to exercise or not. This is important since many athletes don’t really know when to exercise and they might […]

Datarella People – Helge F. Gruetjen, Boat Racer & Physicist

Cambridge PhD student Helge Gruetjen was a chain-smoker, weighting 120 kilograms, who started to row for the Cambridge University Boat Club in 2010 to become one of a team of five trying to beat the Oxford squad. He had set himself an „unrealistic goal“: to lose more than 25 kilograms while bulking up, simultaneously. In the last 2.5 years the 26-year-old managed to lose 0.5 kilograms per week, by stopping smoking, tracking his food intake, sleep patterns and more, using an Excel sheet, 4 hours of training per day…..and a lot of will power. „I knew I had to become very fit within 2.5 years. And I had to lose weight in a very soft and sustainable way.“ But how to motivate oneself to constantly lose weight during 2.5. years? For Helge, to be part of the Cambridge boat race team, was the biggest motivating factor. First, he analyzed his own behavior: which aspects of his life are obstacles to that goal and had to be changed. These were: smoking, exercise behavior, eating behavior, sleep patterns, etc. „We have to get up at 5:45am and start our day with the first round of training. Then I head to my office. […]

Datarella People – Michael Ricks, Self-Tracker, Investment Banker, Inventor

Here’s the transcript of this Datarella (DR) interview with Michael Ricks, self-tracker, investment banker and inventor. DR Michael, you are an American living in Munich, Germany. Could you tell us a little about you? Michael Ok – so, what am I? A guy who is trying to get the most out of life. I’m a father of four kids who are pretty active. I work as an investment banker and inventor, and otherwise I’m just enjoying life. DR How do you track yourself? Michael Probably like everyone does. I get up in the morning and think about what my day is going to bring. Every day I do a thousand repetitions of something or a combination of those thousand things. So, most days I start with a hundred stit-ups in bed! And that’s the beginning of tracking what I’m doing there in the course of the day. Then I figure out how many hours I’ve slept, and then I decide how to spend my day: I look at my calendar, divide up my time, dibide up my activity… and start! DR What reason would there be to stop tracking yourself? Michael If tracking became something which consumed more time and […]

Datarella People – Florian Schumacher, QS Evangelist

Here’s the transcript of this Datarella (DR) interview with Florian Schumacher, Founder QS Meetups, Germany. DR Florian Schumacher, you started the first Quantified Self QS Meetup in Germany. Could you introduce yourself and tell us about your QS approach? Florian When I learned about Quantified Self in 2011, I immediately felt attracted by its very positive culture. Consequently, I started the QS meetups in Berlin and Munich in 2012 which is a lot of fun. Besides, I am a trendscout of Wearable Technologies AG. Here, I’m dealing with all devices you can wear and the sensors which collect behavioral data. DR What do you track yourself and how do you do that? Florian I regularly and passively track my weight, my body fat, my physical activities and my sleep – all those data are collected automatically, so that’s completely effortless. Then, I manually collect sample data on my blood pressure, blood sugar, my girth, and I try to keep an eye on my haemogram. This, I do on a weekly basis. Then I track other data as time, which is quite sophisticated, since it’s not automated at all and I track everything: every project, every lunch, every activity finds its […]
