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.
