Visualization of simultaneous experiences by multi sided recording of an event

Many people have their own camera or recording devices such as cellar phones and digital cameras. When there is a big event, a lot of pictures and movies are taken from various places at the same time. People want to record events with their digital devices as a memory or remembrance. We have some services to share these photos and movies, however, there is no viewer suitable to summarize and integrate these photos and movies for one event. Especially, when one event does not occur at one place but occur in a large area, it is difficult to visualize them. In this paper, we propose a novel viewer which enable people to see various experiences occurred at the same time. The viewer provides us three-dimensional view which includes space axis and time axis. We selected an event that occur in a large area, “the Last Run of the Express Noto”. The Express Noto is a train that runs from Tokyo to Kanazawa in Japan and takes about 7 hours. There is the last run event of the Express Noto in March, 2010. We recorded the event various kinds of recording methods, e.g., a digital camera, an portable movie camera, a voice recorder, tweets at “Twitter” with more than 10 people. Then we apply our data to our viewer that can visualize them three-dimensionally for easy understanding the expanse of simultaneous experience information. For evaluation of our system, we demonstrated this system at “The Railway Museum” in Japan, and find out usefulness which it´s used at museum.
