PersonalAnalytics - Building the Fitbit for Knowledge Workers

Personal Analytics project was originally initiated by Prof. Dr. Thomas Fritz and André N. Meyer from the SEAL Lab at the University of Zurich (UZH). Our goal is to build a self-monitoring tool that knowledge workers (e.g. developers, designers, administrators) install on their computer and that allows them to get insights into their work and productivity, and come up with positive behavior changes. The basis are a number of computer interaction trackers (e.g. application usage, emails/meetings, user input) and biometric trackers (e.g. Fitbit, Polar, Garmin, Muse, Tobii) that non-intrusively track data, store them locally on the users machine (to avoid privacy issues!) and then visualize them in a daily/weekly summary, the retrospection.

Anyone is welcome to extend PersonalAnalytics with new trackers or improve existing ones. Feel free to use PersonalAnalytics to get insights into your own work habits, or use it for research studies. In case you re-use PersonalAnalytics, make sure to cite our work.

Updates & Branches

  • September 2014: Initiated by André Meyer and regularly updated since then.
  • November, 2015: OpenSourced the project (license: MIT).
  • February, 2016: Improved the retrospection and added the Office 365 tracker during an internship at Microsoft Research between November, 2015 and February, 2016
  • April, 2016: Merged the branch (from Microsoft Research) with the original version, following the open sourcing of the code.
  • May, 2016: Started working on a communication dashboard (including more insights into interactions with others) with ABB Research (on a separate branch). This work has never been finished.
  • June, 2016: Started working on integrating the Muse tracker with Monica Rüegg (master student at the University of Zurich, Switzerland) on the 'muse' branch. The branch has not stable enough to merge with master.
  • December, 2016: Started working on integrating several other biometric sensors (Polar, Garmin, Fitbit) (on the 'biometrics' branch). The PolarTracker and GarminTracker are available and stable on the master branch. GarminTracker is still in development.
  • February, 2017: Integrated the (privately developed) FlowLight to avoid interruptions at inopportune moments. It has since then been removed from the repository, as it was licensed to Embrava.
  • March, 2017: Started working on task type detection (on the 'taskdetection' branch), still in development.
  • June, 2018: Rohit Kaushik (bachelor student at BITS Pilani, India) started working on a SlackTracker.
  • September, 2018: Chris Satterfield and Anna Scholtz (master students at University of British Columbia, Canada) started integrating their port from Windows to Mac. Work in progress.
  • September 2018: Jan Pilzer and Raphael started integrating their work on Tobii Eytracking. Work in progress.
