Virtual and Augmented Reality / Human Simulation

Key Research Topics: Virtual Reality, Augmented Reality, Virtual Human Modelling, Human Computer Interaction, Multimodal Interfaces, Infotainment, Serious Games

The group exhibits substantial research activity, both academic and industry-oriented, as well as technology transfer actions, in the area of virtual, augmented and mixed reality. This area includes modeling and simulation of complex virtual environments, haptic force feedback applied research, 3D modeling and compression, deformable objects and cloth modeling, collaborative virtual environments, new sensor development for head/hands/body tracking, multimedia analysis/synthesis, gesture recognition, head motion modelling and tracking, advanced applications of virtual/augmented/mixed reality in education and training, e-health, assistive technologies, culture, industry and e-business. We have developed Virtual and Augmented Reality enabling technologies including object recognition based on 2D and 3D sensing (depth images) as well as activity recognition, computer vision and image processing algorithms for pose estimation, pattern matching and analysis, networked media search and retrieval, natural and multimodal interaction, as well as AR and VR User Interface implementations. The team has also developed a state of the art game engine based on the OGRE open source platform which has already been used to succesfully develop several projects in edutainment, infotainment, serious gaming and virtual cultural heritage persentation projects, funded by GSRT. This engine is constantly updated in order to be used in any project that requires a versatile 3D game/VR engine.
