We’ve featured the work of our friend and QS community member, Doug Kanter, many times here on the Quantified Self website and we were excited to have him participate in our Quantified Self Public Health Symposium. Doug is both a toolmaker and self-tracker, focusing primarily on using his experience with tracking his diabetes-related data to inform new tools and methods. In this talk, Doug explains what he learned from diving headfirst into a year-long project of tracking and visualizing all of the data he could gather about his diabetes self-management, his diet and activity, and other important factors. Beyond the wonderful visualizations he shared, Doug helped highlight something many patients and self-trackers are struggling with, the inability to access data easily and the lack of interoperability among data services and devices. We invite you to watch Doug’s wonderful talk below.
