Abstract |
The research work presented in this thesis aims to contribute a generic and holistic
approach for generating applications substituting (Virtual Reality), enhancing
(Augmented Reality) or interweaving physical and virtual worlds (Mixed Reality) in an
effort to visualize large data volumes that belong to demanding domains such as Big
Data or Cultural Heritage.
Towards this end, a framework is proposed, based on the concepts of Information
Worlds and Information Things, to depict the physical or imaginative environments
that encapsulate information through distinct elements in a scalable and easily
perceivable data model. The framework provides more than 15 ready-to-use
components which can be directly integrated in applications and an extensive
architecture which allows future additions. Moreover, the framework supports the
definition and visualization of personalized stories (either generated by professionals
or by end users). In terms of interaction, this thesis proposes the usage of multimodal,
natural means of interaction, seamlessly integrating Augmented, Virtual and Mixed
Reality applications in Ambient Intelligence environments.
The Information Worlds framework can constitute a valuable asset for the creation of
dynamic visualizations using X Reality, providing interoperability with various data
sources, ready to use tools to visualize information, extensibility for additional
components and a scalable conceptual model which suits diverse needs.
The use case of a smart museum is presented, depicting highly interconnected and
sparsely located information in the demanding context of Cultural Heritage using
augmented and virtual reality. Moreover, the use case of a real time data center
infrastructure management application showcases the framework’s ability to cope
with high velocity, large data volumes which are congested. Results of this work have
been deployed in public space installations, temporary exhibitions and international
conferences. Each use case has been evaluated by more than 20 users in order to
assess the final results produced by the Information Worlds framework in terms of
usability and user experience. The excellent results reported in the evaluation
illustrate the potential of AR, VR and MR in terms of efficiency and technology
adoption by end users, but also constitute a motivation for further improving and
extending the presented framework.
