About

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.

Garmin Edge 500

Garmin Edge 500 is a light weight GPS initially designed for bike riders. But it is also good for walkers. I put it in the small pocket at the top my sack that I carry everyday. For its performance test, I carried it on the way to back to home by walk. Below screenshots show its performance and accuracy very well in comparions with iPhone 3GS. 

The first image is the GPS record of Garmin on my commuting route from my office at POVO to my home at TRENTO downtown. It shows my route precisely. On average, the route error was less than 10 meters. The biggest one is about 40 meters away from the route and I was walking under the tree. This route is like getting down from the moutain top. So it was like walking through the woods.

This image is the result of iPhone 3GS. I turned it on at the same time with Garmin. It only records a portion of my route when I am completely exposed to the sun light (where no tree over my head). No needs for comparison. Garmin win!
