The main research area of our laboratory belongs into the research field of Future Internet. A common implication of research in the Internet of Things (IoT) and 3D Internet (3DI) is that 3D virtual environments are expected to be inter-connectible in the near future, allowing for the sharing and manipulation of distributed objects and systems. In this context, our primary goal is to design, implement and integrate solutions enabling communication, collaboration and control in augmented and shared 3D environments.

Main research areas

Cognitive Infocommunications
The primary goal of cognitive infocommunications (CogInfoCom, http://www.coginfocom.hu) is to enable the merging of human cognitive capabilities with the rapidly evolving and increasingly sophisticated artificial cognitive capabilities of infocommunications systems (e.g., personal informatics devices, virtual spaces, Future Internet). Through these goals, CogInfoCom aims to support the communication and collaboration needs of humans surrounded by modern infocommunications infrastructure.

Control Theory
The research laboratory also deals with systems and control theoretical methodologies which can be applied automatically and in uniform ways even when a dynamics problem is not formulated using “classical”, analytic closed forms, but rather using soft computing approaches (e.g., neural networks, genetic algorithms, fuzzy systems) or other representations resulting from automatic identification techniques.
Systems and control theoretical problems are usually addressed by our laboratory using linear and quasi-linear parameter varying (LPV) representations and linear matrix inequality (LMI) based methodologies, as well as automatic and uniform design methodologies based on the tensor product model transformation.

Research results

- The development of a new school for the treatment of a large class of stability problems was inspired by the TP model transformation based systems and control theoretical results of the research laboratory. Using the TP model transformation, it is possible to to transform models formulated in various representations into a polytopic form, and to further manipulate them for the direct applicability and optimization of linear matrix inequality-based analysis and synthesis techniques. Time delay systems can also be handled to some degree using the TP model transformation. The laboratory has developed a system design toolbox based on these approaches.

- By laying down the foundations of cognitive infocommunications, the laboratory proposed a radically new approach for research on and application design for the interaction between humans and modern infocommunications devices in today’s increasingly networked environment. Results of the laboratory extend to the synthesis and analysis of information-carrying channels as well as a description of the interactive structure and modes of communication (further information can be found at http://www.coginfocom.hu ).

- The laboratory developed a pilot solution for 3D virtual collaboration in Future Internet, which allows users to share and integrate knowledge-based components and other devices physically and/or virtually located at different laboratories. The system provides a shared 3D virtual space to all users, allowing them to design, implement, monitor and test integrated systems, and to collaborately manipulate their components through 3D interaction. The laboratory gave a first ever demonstration at an international forum of such a system in operation across the laboratories of several universities (further information can be found at http://www.virca.hu ).
