Data Management for Augmented Reality Applications
Augmented Reality is a new technology that combines real and virtual environments.
In general glasses with attached displays are used to produce visual augmentations of the
user’s environment. These so-called head mounted displays are able to project virtual objects
that are registered with the real world of the user.
The DWARF project is conducted at the Chair for Applied Software Engineering of the
Technische Universität München and tries to use methods from software engineering to
reuse components for faster prototypical implementation of new components.
DWARF consists of a set of software services that act on mobile distributed hardware and
can communicate via wireless or wired networks. This communication allows to carry per-sonalized
mobile devices with embedded services, while intelligent environments provide
location based services. The services discover each other and dynamically cooperate to provide
desired functionality, which is required for Augmented Reality applications.
A critical issue of Augmented Reality is the large quantity of data, which must be managed
in a distributed system. This data must be reliably delivered to services that provide user
access on that data. The handled data must be in a consistent state allover the system.
Database systems can be used for parts of the management of data to guarantee persis-tence
and efficient handling.
This thesis deals with data management for distributed Augmented Reality systems. The
main contribution of this thesis is a novel approach of dynamic services, that give the user
transparent access to all necessary data. The developed design has prototypically been implemented
and tested within the ARCHIE application. ARCHIE states a project to support
architectural modeling by Augmented Reality.
By further development a set of general usable services can be realized that allows to use
Augmented Reality in new areas.
