scene it is winter and snowing, tourists can choose AR
content
such as augmented snow and a snow-covered field. Also, users
can edit and share user-generated content such as tags,
text,
pictures
and
videos with others at watching
points and acting
points. This content contains information about modified

reviews.
5 CONCLUSIONS AND FUTURE WORK
In this paper, we propose the 5W1H metadata schema, which
provides location-based film experiences on the AR platform. A
standardized and formulated metadata schema is critical in a
ubiquitous computing environment because interoperability and
reusability of the data should be guaranteed between different
systems and devices. In this regard, the 5W1H metadata schema
will be a promising alternative for interpretation and management.
When we design metadata, we also consider how to provide a new
experience with video content in an augmented location. With this
metadata, people can enjoy an enriched and dynamic experience
beyond a passive and static manner.
However, for accurate context awareness of related objects, it is
necessary to use not only the sensors of the user’s mobile phone
but also external sensors and devices. In this paper, how to use
such external embedded sensors and manage their metadata
remains unclear. Moreover, we did not validate the efficiency or
accuracy of this metadata schema.
In future work, we will implement the AR mobile application
while utilizing the proposed 5W1H metadata schema. Qualitative
and qualitative experiments will evaluate the system, and the
proposed metadata will be complemented and modified to
improve the location-based multimedia experiences on the AR
platform.
