Virtual reality system allowing immersion in virtual space to consist with actual movement in actual space
First Claim
1. A virtual reality system, comprising:
- a play ground defined within an actual space of a real world to have a predetermined area in which a user may walk or run;
a head mounted device having a display for displaying a fully virtual image of a virtual space formed corresponding to real objects in the play ground and worn by the user to surround both eyes;
at least one sensor attached to a predetermined location in the play ground, the head mounted device and/or a body of the user to sense an actual location and/or motion of the user in the play ground; and
a processor configured to calculate an actual location and a facing direction of the user in the play ground according to a signal received from the at least one sensor, and control the head mounted device to display a fully virtual image of the virtual space, observed at the actual location and in the facing direction of the user, on the display,wherein when the user wearing the head mounted device actually walks or runs in the play ground, the processor controls the head mounted device to display a fully virtual image of the virtual space corresponding to the actual location and in the facing direction of the user after walking or running, wherein the at least one sensor includes;
an emission element mounted to the head mounted device to emit an electromagnetic wave of a predetermined wavelength; and
at least two detection elements installed at predetermined locations in the play ground to detect the electromagnetic wave,wherein the emission element includes two emission elements spaced apart from each other by a predetermined distance, and the at least two detection element respectively sense locations of the two emission elements by detecting both of electromagnetic waves emitted from the two emission elements, andwherein the processor calculates locations of the two emission elements, respectively, according to signals input from the at least two detection elements, calculates a center point of the locations of the two emission elements as a current location of the head mounted device, and calculates a direction of a perpendicular bisector at the locations of the two emission elements as a current facing direction of the head mounted device.

Abstract
A virtual reality system includes a playground defined within a real world space to have a predetermined area in which a user is movable, a head mounted device surrounds both eyes displaying an image of a virtual space formed corresponding to real objects in the playground, a sensor attached to a predetermined location in the playground, the head mounted device or body of the user sensing an actual location or motion of the user in the playground. A control unit calculates a location and direction of the user in the playground according to a signal from the sensor, and displays an image on the head mounted device of the virtual space, observed at the location and in the facing direction of the user. When the user wearing the head mounted device actually moves in the playground, a feeling of moving in the virtual space is given to the user.
