QS Gallery: Bill Schuller

November 12, 2013

Today’s QS Gallery entry comes to us from Bill Schuller. Be sure to check out his blog, Data Obsessive, to learn more about this visualization and other interesting self-tracking projects.

A driver made a left turn from a stright-only lane right in front of me as I was proceeding straight through the intersection from my straight or left lane. I have occasionally turned on the accelerometer and gyro logging in FluxStream Capture while I drive. This time around, I have even more data. You can see the massive deceleration and the associated spike in my heart rate and drop in my beat spacing (RR). I haven’t pulled my GPS data yet, but I was able to spot this easily in the FluxStream graph. Those dips in the Acceleration data really stand out. Interestingly, my heart rate also reflects my mood afterward.

Initially relieved that I didn’t get hit this time, then enraged that it had nearly happened again, calming slowly as I composed in my head a letter to the City of Addison imploring them to add more signage at that intersection.

New QS Devices

While a student at UC Berkeley, I was awed by the miniaturized devices created in the engineering department for neuroscientists. Eventually, these devices will enable entirely new kinds of Quantified Self projects. Here are three especially promising projects I came across while studying for my degree in neurobiology.
