Abstract: The invention relates to television, interactive television, user interfaces, video conferences and may be used in the creation of video programs with interactive interaction between participants of video programs and objects generated by a computer program. The technical result is enhancement of the reliability and quality of the display to viewers of images, formed by a computer, and the reaction of participants of a video program to a change of the images. A participant 2 of a video program is shot by a video camera 1, wherein an image, formed by a means 3 (computer), is simultaneously displayed to the participant 2 on the line of shooting with the video camera.

Abstract: A system for immersing a user in virtual reality comprises a closed sphere-shaped capsule defining a real environment, the capsule being installed on supports so that to rotate around its center and having at least one hatch equipped with a door to let the user in and out. The system includes virtual environment generating means and means for displaying the virtual environment to the user, connected to the virtual environment generating means. The system further comprises a unit for changing the virtual environment responsive to actual physical movements made by the user inside the capsule, and means for determining an amount and direction of user's movement relative to the capsule, connected to the virtual environment changing unit. The capsule rests on at least three wheel supports having pivot shafts directed toward the sphere center and offset relative to a rotational axis of the wheel.

Abstract: The invention relates to methods and systems for determination of position and orientation of users in a space and display of virtual space, and can be used in interactive computer games, health-strengthening teaching devices, or trainings of the athletic and military purposes. The invention provides an improved accuracy and speed of tracking of the user's spatial position and orientation, provides convenience for and naturalness of his/her movements and representation of virtual space in conformity with user's movements in the real space. Sensors 4 for tracking angular position of segments 2 of the user's locomotor system are attached at places of articulations 3 of segments 2 and at certain segments 2 proper. At least at one of segments 2 arranged are main means 5 for determination of reference directions, which means provide determination of orientation of a given segment relative to the reference directions.
