knowledge about the region and discover something
by watching the videos recorded in the area just
nearby their homes. A lot of people treat the place as
dots, because they normally move by means of
transportation such as car, train, and bus in their city.
But this use case enables users to realize what
happens in several directions spatially. Secondly,
users fix the direction, and then change distance with
watching movies. In this case, users can realize the
transition of culture by expanding the distance. For
example, if Japanese users expand the distance
toward west, they can watch Japanese contents,
Chinese contents, European contents and so on in
sequence. As just described in these use cases, users
can obtain information with recognizing the space
around the world.

5 DISCUSSIONS
In order to get some initial user feedback, we made a
demo of CQ Submarine at an exhibition on travel
applications that was held in Tokyo in September
2011. In that exhibition, we received a variety of
opinions with some visitors using CQ Submarine
after that event. When users set the distance and
direction, most of them tend to decide the place such
as the their home city, the place where they travelled
before and so on in advance. Of course they missed
the point at first, however, they guessed which
country the current places were from the information
in the videos such as the look of people, buildings
and character. In this process, especially, users were
amazed when Japanese language changed to
Chinese, Turkish, and French by expanding the
distance from Japan to west. At last some users
reached the videos recoded at the place where they
intended at first. A lot of users were surprised that
their sense of distance and direction missed the
points of real.
6 RELATED WORKS
As a research which relates image browsing and
spatial location information, Snavery, Seitz, and
Szeliski presented “Photo Tourism “. This system
enables users to browse through Internet snap shots
that have been arranged into virtual 3D space by
finding similarities between the images. There are
also some web services such as “flickr” or
“panoramio” and “google maps” in which users can
browse pictures or videos on maps. These ideas
shows the value of browsing contents by relating
them to location information, however there are no
case which use distance and direction as an interface.
Some AR applications such as “Sekai Camera” or
“Layer” presents interface which uses real-world
experience, but they are different in that the area is
extremely small from our research.
7 CONCLUSIONS
Initial feed back from users indicates CQ Submarine
is useful to provide imagination, amazement and
discovery in searching process. This results indicate
that the concept of CQ Submarine is expected to
work for a variety of areas such as education,
tourism, and culturology. We believe that making
scope for imagination in searching process is a
useful activity that may lead to a variety of
innovative applications.
