      Learning through multi-touch interfaces in museum exhibits: An empirical investigation 

      Zaharias, Panagiotis; Michael, D.; Chrysanthou, Yiorgos L. (2013)
      Interactive technologies are employed in museums to enhance the visitors' experience and help them learn in more authentic ways. Great amounts of time and money and many man-hours of hard work have been spent. But do such ...

      Market model for level of detail control 

      Howell, J.; Chrysanthou, Yiorgos L.; Steed, A.; Slater, M. (ACM, 1999)
      In virtual reality simulations the speed of rendering is vitally important. One of the techniques for controlling the frame rate is the assignment of different levels of detail for each object within a scene. The most ...

      Real-time shadows for animated crowds in virtual cities 

      Loscos, C.; Tecchia, F.; Chrysanthou, Yiorgos L. (2001)
      In this paper, we address the problem of shadow computation for large environments including thousands of dynamic objects. The method we propose is based on the assumption that the environment is 2.5D, which is often the ...

      Reputation-based mechanisms for evolutionary master-worker computing 

      Christoforou, Evgenia; Fernández Anta, Antonio; Georgiou, Chryssis; Mosteiro, Miguel A.; Sánchez, A. (2013)
      We consider Internet-based Master-Worker task computing systems, such as SETI@home, where a master sends tasks to potentially unreliable workers, and the workers execute and report back the result. We model such computations ...

      Scalable pedestrian simulation for virtual cities 

      Stylianou, S.; Fyrillas, Marios M.; Chrysanthou, Yiorgos L. (2004)
      Most of the common approaches for the pedestrian simulation, used in the Graphics/VR community, are bottom-up. The avatars are individually simulated in the space and the overall behavior emerges from their interactions. ...

      SocialRobot: An interactive mobile robot for elderly home care 

      Portugal, D.; Santos, L.; Alvito, P.; Dias, J.; Samaras, George S.; Christodoulou, Eleni (Institute of Electrical and Electronics Engineers Inc., 2016)
      SocialRobot is a collaborative European project, which focuses on providing a practical and interactive robotic solution to improve the quality of life of elderly people. Having this in mind, a state of the art mobile robot ...

      Transactive memory in task-driven 3d virtual world teams 

      Kleanthous, Styliani; Michael, Michalis A.; Samaras, George S.; Christodoulou, Eleni (Association for Computing Machinery, 2016)
      Collaboration and knowledge sharing in small teams is very usual not only in education but also in industry, in gaming and in our lives. Interdisciplinary teams are formed and their members are expected to collaborate, ...

      Upper limb assessment of people with multiple sclerosis with the use of a haptic nine hole peg-board test 

      Xydas, E. G.; Louca, Loucas S. (Affiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, CyprusCorrespondence Address: Xydas, E. G.Department of Mechanical and Manufacturing Engineering, University of CyprusCyprus, 2009)
      In this work, a nine-hole peg-board test (NHPT) arrangement is implemented in a Virtual Environment with the use of a Haptic Interface that has the form of a small robotic arm. The Haptic NHPT is used as a mean for ...

      Upper limb motion profile during small to medium time-limited reaching tasks in A VR based robotic training environment 

      Xydas, E. G.; Louca, Loucas S. (Affiliation: University of Cyprus, Department of Mechanical and Manufacturing Engineering, 75 Kallipoleos Street, Nicosia 1678, CyprusCorrespondence Address: Xydas, E. G.University of Cyprus, Department of Mechanical and Manufacturing Engineering, 75 Kallipoleos Street, Nicosia 1678, Cyprusemail: mep4ex1@ucy.ac.cy, 2008)
      In the area of rehabilitation robotics, many researchers have investigated the therapeutic effects of forces that are proportional to the difference of the user's hand trajectory with an optimum trajectory that is usually ...

      View volume culling using a probabilistic caching scheme 

      Slater, Mel; Chrysanthou, Yiorgos L. (ACM, 1997)
      This paper a new algorithm for view volume culling. During an interactive walkthrough of a 3D scene, at any moment a large proportion of objects will be outside of the view volume. Frame-to-frame coherence implies that the ...

      Virtual crowds, a contributing factor to presence in immersive virtual environments 

      Kyriakou, Marios A. (Πανεπιστήμιο Κύπρου, Σχολή Θετικών και Εφαρμοσμένων Επιστημών / University of Cyprus, Faculty of Pure and Applied Sciences, 2014-06)
      Καθώς η χρήση των πολυμέσων και της τεχνολογίας 3 διαστάσεων αυξάνεται σε πολλούς τομείς της ζωής μας, οι απαιτήσεις μας για περισσότερο "ρεαλισμό" επίσης ανεβαίνουν. Στα περισσότερα συστήματα εικονικής πραγματικότητας ...

      Visualizing crowds in real-time 

      Tecchia, F.; Loscos, C.; Chrysanthou, Yiorgos L. (2002)
      Real-time crowd visualization has recently attracted quite an interest from the graphics community and, as interactive applications become even more complex, there is a natural demand for new and unexplored application ...
