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.

Outdoor activities -- Motorbike rider's favorites are different

Bike riders often attach one or two GoPro cameras each on the bike and their helmet to record their driving life on the road. They also commonly carry GPS units to track their paths and to record the speed. We asked them whether they have ever reviewed their videos and the answers were same, "No." Simply the reason is the fact driving on the road is rather monotonous mostly the scene is filled up with roads and cars.

The next question is then what they would ask to the computer, assuming very intelligent computer, to show them what moments? Interestingly the moment they want to ask is most dangerous moments like when (1) reaching the highest speed, (2) turning the sharp corner almost nearly touching the ground, (3) passing over slow cars or (4) breaking sharply to avoid collision.

So now we understand that they really enjoy thrills but what multimedia retrieval experts should do to create a summary of videos for bike riders?
