Аннотация: the article reviews techniques and architecture of a system for transferring “live” lectures into virtual world vAcademia. The system records lector’s voice and uses Microsoft Kinect for capturing teacher’s gestures transforming this data into lector’s avatar animation. With the performance capabilities of streaming processors the content of the projector’s screen used by teacher is transferred directly to the virtual world and displayed in shared graphical workspace, and the additional analysis of the image from Kinect video camera is performed to more accurately determine the position of the body of the teacher. The stream processors allowed eff ectively implement the projector’s screen transfer to the virtual world shared workspace and also capture and recognize colored makers on the teacher’s body with little or no loss of performance. Using Kinect for lecture capture together with capturing image from the projector or interactive board and displaying it in the virtual world could allow teachers to use virtual worlds as a powerful learning tool while remaining in the familiar learning environment. That is the purpose of this research.

Аннотация: The authors suggest method of teaching the tactical actions by simulating game situations in virtual reality. A database of players is filled on the server, the coach forms the attacking and defending teams, their initial placement and the location of implement at the field, that will be sent to the players’ computers. The players of attacking ream try to bring the virtual game object to the affected area or to hit the gate of the defending team. Players of the defending team tries to possess the virtual game object and to prevent the actions of the attacking team. The proposed method allows to simulate and unlimited number of game situations, analyze different scenarios and improve the game thinking and interaction of players. It can be used for tactical teaching in teams of varying level of training specializing in football, hockey, handball, rugby, basketball and other team sports.

Аннотация: 3D-record of a lesson is a powerful tool for education in virtual worlds. However, as with the video records, the 3D-record needs to be edited by the teacher to turn into a high-quality educational content. As opposed to a video stream a 3D-record is a complex sequence of changes of synchronized properties bound to the timeline that starts from the beginning of the lesson. 3D-record editing capabilities require solving number of technical problems related to the size of the original data, removing unnecessary resources, speed of the record replay and the size of the network packages. The article is devoted to these issues.

Ключевые слова: Software, 3d-content, editing, virtual worlds, 3d-record, education, synchronization, multimedia, resources, collection
