Abstract

A method for immersion of a user into virtual reality consisting in that a closed shell limiting a real closed space is formed and the shell is arranged on a support means with the possibility of rotation about its center. A user who has the possibility for free movement along the inner surface of the shell is placed in the shell. Wherein the shell turns in a direction opposite to the direction of movement of the user due to the effect of the moment of force produced when the center of gravity of the user is displaced relative to a vertical passing through the center of the shell. Then a virtual space is formed in which objects appear and move in a predetermined and random manner. This formed virtual space is displayed to the user. Continuous conversion of the virtual space is carried out in accordance with real physical hand, foot and head movements of the user in the real space, taking into account interaction with the objects in virtual space.

Claims

1. A method for immersion of a user in virtual reality comprising:

forming a closed shell having a center and an inner surface,

setting up a support means,

mounting said shell on said support means for rotation on the support means about said center of rotation,

wherein a user has a freedom of movement along said inner surface of said shell, and wherein a center of gravity of the user moves relative to a vertical axis passing through said center of the shell,

providing the user with means for displaying a virtual space,

forming a virtual space comprising virtual objects by means of computer means,

displaying the formed virtual space to the user inside said shell on said means for displaying the virtual space, wherein interaction of the user with the objects of the virtual space is effected by movement of the user relative to a point of support,

turning the shell under the effect of a force produced when said center of gravity of the user is displaced relative to the vertical axis passing through the center of the shell, the shell being turned in a direction opposite to the direction of movement of the user,

determining magnitude and direction of change of a position of the user relative to said shell,

modifying virtual space in accordance with physical hand, foot and head movements of the user inside said shell, taking into account interaction with said objects in the virtual space,

modifying the virtual space in accordance with the obtained magnitude and direction of movement of the user and displaying the virtual space to the user.

2. A method as in claim 1, which includes rotating said shell in a forced manner using means for forced rotation so as to reduce the deviation of the center of gravity of the user from the vertical axis passing through the center of the shell.

3. A method as in claim 1 wherein the shell has a closed convex surface.

4. A method as in claim 3 wherein the closed convex surface is a sphere.

5. A method as in claim 1 which comprises arranging at least three ball supports under said shell, the three ball supports serving as said support means.

6. A method as in claim 1 wherein the shell is perforated.

7. A method as in claim 1 wherein the shell is made of transparent material.

8. A method as in claim 1 which comprises arranging said means for forming a virtual space outside of the shell.

9. A method as in claim 1 which comprises arranging the means for forming a virtual space inside the shell.

10. A method as in claim 9 which comprises arranging the means for forming a virtual space on the user.

11. A method as in claim 1 which comprises arranging a support means for securing ancillary means for forming virtual reality inside the shell.

12. An apparatus for immersion into virtual reality comprising

a shell having a center and an inner surface,

a support means on which said shell is arranged for rotation, wherein the shell turns when center of gravity of a user is displaced relative to a vertical axis passing through the center of the shell, the shell being turned in a direction opposite to the direction of movement of the user,

means for forming a virtual space comprising virtual objects,

means for displaying the formed virtual space to the user, connected to the means for forming a virtual space,

a unit for modifying the virtual space in accordance with physical movements of the user, taking into account interaction of the user with the objects in the virtual space,

means for determining magnitude and direction of movement of the user relative to a point of support of the user on the shell, wherein the means for determining is connected to said unit for modifying the virtual space.

13. An apparatus as in claim 12 which additionally comprises

means for rotating the shell, connected to said support means, so as to reduce the deviation of the center of gravity of the user relative to the vertical axis passing through said center of the shell.

14. An apparatus as in claim 12 in which said shell is a closed convex surface.

15. An apparatus as in claim 14 in which said closed convex surface is a sphere.

16. An apparatus as in claim 12 in which said support means comprises at least three ball supports.

17. An apparatus as in claim 12 in which the shell includes perforations.

18. An apparatus as in claim 12 in which the shell is made of transparent material.

19. An apparatus as in claim 12 in which said means for forming virtual space is arranged outside of said shell.

20. An apparatus as in claim 12 in which said means for forming virtual space is arranged inside of said shell.

21. An apparatus as in claim 20 in which said means for forming virtual space is arranged on the user.

22. An apparatus as in claim 12 which additionally comprises a quasi-stationary support for securing ancillary devices for forming virtual reality.

23. An apparatus as in claim 22 in which one or more devices selected from a group consisting of a wheelchair, imitating means for movement, a ball, dummies and devices imitating behavior of an opponent in combat are used as said ancillary devices.

24. A method for immersion of a user in virtual reality using a shell mounted on a support means for rotation, wherein a user is positioned within the shell and provided with means for displaying a virtual space comprising:

forming a virtual space comprising virtual objects by means of a computer,

displaying at least a portion of the formed virtual space to the user using the means for displaying the virtual space,

turning the shell when the center of gravity of the user is displaced relative to a vertical axis passing through the center of the shell, the shell being turned in a direction opposite to a direction of movement of the user,

determining magnitude and direction of change of a position of the user relative to the shell,

modifying the virtual space on the basis of the determined magnitude and direction of movement of the user and

displaying at least a portion of the modified virtual space to the user.
