“…Based on a formal representation of its components, the proposed architecture provides a scalable VR system. Paper [6] discusses object-oriented virtual worlds building process, utilizing the software development technique of stepwise refinement, and possibilities of parallel processing in VR systems. Papers [7][8] present current research efforts and useful applications that employ 3D graphics with particular focus on addressing the unique features of mobile devices (ubiquity, connectivity, contextawareness, and multimodal interfaces).…”

The main novelty presented in this paper is application and evaluation our Gesture Description Language (GDL) classifier in the role of touchless interface for virtual reality (VR) environment. In our VR system whole interaction is done by gestures and body movements analysis (so called natural user interface). For our needs we have adapted semi-realistic VR system (block engine). We have tested different aspects of proposed interface on a group of 26 persons with wide range of age (from 5 years to 40+) and both sexes. The results we obtained prove that GDL can be successfully applied in systems that require real time action recognition especially educational software games that aim at increasing the students' motivation and engagement while they learn. Streszczenie. W tym artykule autorzy prezentują zastosowanie klasyfikatora o nazwie Język Opisu Gestów (GDL) w roli bezdotykowego interfejsu systemu wirtualnej rzeczywistości. Całość interakcji z zaprezentowanym w tej pracy systemem odbywa się poprzez rozpoznanie i analizę ruchu użytkownika (jest to tak zwany interfejs naturalny). Klasyfikator GDL został przetestowany w pseudo-realistycznym, wirtualnym środowisku, na grupie 26 osób obu płci w przedziale wiekowym od 5 do 40+ lat. Otrzymane rezultaty dowodzą, że zaproponowane podejście może być z powodzeniem użyte w aplikacjach wykorzystujących wirtualną rzeczywistość, w szczególności w grach edukacyjnych, których celem jest uatrakcyjnienie procesu zdobywania wiedzy.

“…Representation of virtual reality via 3D technologies gives more authenticity and credibility. Virtual reality (VR) and related technologies are penetrating almost every aspect of our lives [1]. Nowadays, it is one of the most developing technologies that could significantly increase the level of interactivity [2].…”

This chapter is dedicated to the description of 3D computer graphics used for the needs of virtual reality. Virtual reality (VR) is the use of computer technology to create a 3D virtual environment. The chapter presents some graphical features used in an environment as well as an explanation of good design practice. The chapter contains also the description of lighting settings, 3D objects/models and virtualization sequence, camera, and scenes where the wheelchair simulator is used as an example of the implementation environment.
