from its introductory beginning and across its 446 pages, centered around the notion that computer simulations and games are not at all disparate but very much aligning concepts. This not only makes for an interesting premise but also an engaging book overall which offers a resource into an educational subject (for it is educational simulations that the(More)
Invisible, attentive and adaptive technologies that provide tourists with relevant services and information anytime and anywhere may no longer be a vision from the future. The new display paradigm, stemming from the synergy of new mobile devices, context-awareness and AR, has the potential to enhance tourists’ experiences and make them exceptional. However,(More)
Today serious games, i.e. software applications developed with game technology and design principles for a primary purpose other than pure entertainment, include games used for educational, persuasive, pedagogical, political, or health and training purposes. This paper describes the work-in-progress development of an interactive 3D training application(More)
The existing techniques used for post stroke rehabilitation have sought to offer stroke survivors with upper extremity motor deficits a system for the practice and re-learning of motor tasks. Some studies suggest that the use of Virtual Reality technologies as an assistive technology in combination with conventional therapies can achieve improved results in(More)
While traditional computer graphics research to this day still focuses on the production and assessment of photorealism, a relatively new field, the one of nonphotorealistic rendering (NPR), has produced results that focus on viewer engagement by the use of stylization, abstraction and expressiveness. In this paper we briefly describe some of the techniques(More)
This paper presents a comprehensive procedural 3D modelling solution called Virtual City Maker, which relies on scripting algorithms for automatic generation of photorealistic virtual urban content. This solution uses the combination of aerial images, terrestrial photographic input and 2D ground maps in conjunction with a user-friendly customized interface(More)
