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?
