1 INTRODUCTION
Augmented reality is gaining attention as a new form of media in
which people can have new experiences with various types of
content on the AR platform [1]. However, thus far, most
researchers have focused on retrieving multimedia content in
limited contexts, such as the user’s geographical location, and
with simple user profiles [2,3,4]. These partial functionalities of
context-awareness have prevented the development of interactive
and intelligent multimedia services. A smart multimedia service
should consider integrated context-awareness of places where
multimedia content is represented, the people who enjoy the
content, and content that is provided through ubiquitous media [5,
6].
Therefore, we design an AR video service that provides a
location-based film experience in augmented places as a new way
to provide multimedia content in a ubiquitous computing
environment. For this service, the system should consider the
contexts of the places, the user, and the video. The context-aware
service is available when the system collects information from
various sensors and distributed computing resources, integrates
them, and infers the situation of the user and the environment [7].
Furthermore, it should be able to use earlier context information
to improve the customized service. With regard to this point,
standardized metadata is essential in terms of interoperability and
reusability of the data.
In this paper, we propose what is termed the 5W1H (Who,
When, Where, What, How, Why) metadata schema, which is
efficient when used to categorize a variety of information and
intuitive for interpreting the contexts of objects. Although there is
research about metadata and descriptions of AR contents, most
did not consider integrated contexts, including augmented places
and the content of the video. The 5W1H metadata schema will be
implemented in a location-based film experience service for filminduced
tourism. For this type of tourism, people visit the filming
locations where their favorite movies or TV series were filmed for
a more immersive experience of the content [8]. As they use the
service, a navigation system guides tourists to follow the storyline
of the films and TV shows, where they can watch the video clip
from the director’s position. It is also possible to enjoy additional
AR contents associated with the video scenes.
This paper is organized as follows. We review related work in
Chapter 2, after which we propose the 5W1H metadata schema
and explain the system design in Chapter 3. Subsequently, we
describe examples of its use in Chapter 4. We conclude the paper
and suggest future work in Chapter 5.
