The eLog library was initially developed as a research prototype and later published for lifelogging researchers in 2010 to help them easily analyze heterogenous data and complex visualization. It has been kept growing with the progress of mobile computing environments and recently its UI part is released with GPL v3 license for wider usage. The eLog UI library is optimized for mobile environment and can get easily integrated with existing Web services.

Who We Are

The original work was proposed by Pil Ho and later extended the work with collaboration with 28 researchers around the world who contributed their lifelogs, collaborated for lifelog analysis and share research results to build up an open lifelogging platform for the public. Pil Ho has been keeping the development updating the library following up the progress in mobile computing.


  • Nov. 2014: Change the web page skin using bootstrap.
  • Nov. 2014: Published elog UI library as GPL v3.
  • Oct. 2014: Version up eLog library and documentation.



Lifelogging starts from objective monitoring of a user digitizing human actions using various sensors. This category includes our hands-on experiments testing or developing various lifelogging sensors. We recently bought a new hardware system including the GoPro 3D system, Garmin Edge 500, an external hard drive case, a battery charger to build up a new Phase-II life log experiment and more soon. I was satisfied with the first testing result and here the course of e-log system design will be recorded for your information.
