Description

Title of the invention: Embedded virtual reality room

[0001] The present invention relates to the general field of means of communication.

[0002] The present invention relates more particularly to means of diffusion audiovisual equipment such as virtual reality rooms.

[0003] Virtual reality rooms are difficult to transport, require substantial transport logistics and a large and qualified assembly team.

[0004] Virtual reality headsets immerse the viewer in another visual environment, but have the disadvantage of isolating viewers, disrupting discussions between them and not offering a collective immersive experience.

[0005] Conventional virtual reality rooms immerse the viewer in another visual environment, but have the disadvantage of being rectangular, expensive and difficult to transport.

[0006] In addition, virtual reality rooms are generally square or polygonal and offer a low perception of immersion.

[0007] In addition, hemispherical virtual reality rooms are very expensive both for their construction and for the production of media, require the integration of specific equipment, are fragile and are difficult to transport.

[0008] In addition, cylindrical or spherical virtual reality rooms often have the disadvantage of imperfect geometry and an irregular surface.

[0009] The objects assigned to the present invention therefore aim to remedy the various disadvantages listed above and to propose a new mode of audiovisual broadcasting with an embedded virtual reality room.

[0010] Another object assigned to the invention aims to provide an embedded virtual reality room that is easily transportable.

[0011] Another object assigned to the invention aims to provide an embedded virtual reality room that allows installation by a small technical team.

[0012] Another object assigned to the invention aims to provide a cylindrical embedded virtual reality room which offers a good perception of immersion to all visitors, a free movement visiting space, an attractive space promoting the shared immersive experience.

[0013] This invention relates to an embedded virtual reality room, characterized in that it is cylindrical and comprises: - a platform module - a petal-shaped structural module, - a retractable source module, - an immersive screen module,

[0014] Other features characteristic of the invention will become clearer upon reading the following description and with the aid of the accompanying drawings:

[0024] According to the invention, the embedded virtual reality room (1) measures approximately seven meters in internal diameter.

[0025] According to the invention, the embedded virtual reality room (1) is not limited in size and can be adapted with the same device for smaller or much larger dimensions.

[0026] It is noteworthy that the retractable source module (4) includes the most expensive and strategic components of the embedded virtual reality room (1).

[0028] Advantageously, the on-board virtual reality room (1) has two configurations: the operating configuration illustrated in [Fig.1] and the transport configuration illustrated in [Fig.2].

[0029] Conventionally, the rigid longitudinal roof (9) houses the embedded virtual reality room (1) in its transport and operating configurations and supports the attachment of any side protective tarpaulins in operational configuration (not shown).

[0030] In a conventional manner, the programmable logic controller (16) allows the control and servo control of the deployment and retraction kinematics of the embedded virtual reality room (1) to switch from the operating configuration illustrated in [Fig.1] to the transport configuration illustrated in [Fig.2] and vice versa from the transport configuration illustrated in [Fig.2] to the operating configuration illustrated in [Fig.1].

[0035] It is noteworthy that the four curved guide-stops (24) guide and wedge the rolling ball joints (23) of the four deployable segments (18) from the operating configuration illustrated in [Fig.1] to the transport configuration illustrated in [Fig.2] and vice versa from the transport configuration illustrated in [Fig.2] to the operating configuration illustrated in [Fig.1]

[0036] In a conventional manner, the four deployable segments (18) are articulated together by the three hinges (19).

[0037] It is noteworthy that each of the four deployable segments (18) of the petal structure module (3) consists of secondary columns (20), equipped with one or two of the three hinges (19), stiffened by one of the four secondary braces (21), equipped with two of the arcs of the eight-arc support-tension rail (22), and placed on the platform module (2) by means of the rolling ball joints (23).

[0038] According to the invention, the four deployable segments (18) of the petal structure module (3) are deployed by means of the two winches (25), are stiffened by the secondary columns (20) and the four secondary braces (21), roll on the rolling ball joints (23), their guidance and shimming being controlled by means of the four curved guide-stops (24) to move from the initial deployment phase illustrated [Fig.3] to the advanced deployment phase illustrated [Fig.4].

[0039] It is noteworthy that the quadrilateral (10) serves as a geometric reference during the deployment sequence of the virtual reality room (1).

[0040] In a conventional manner, the screen magazine drum (34) unrolls the rollable immersive projection screen (33), during the deployment sequence as illustrated in the advanced deployment phase of [Fig.4].

[0041] In a conventional manner, the roll-up immersive projection screen (33) slides in the rail in eight support-tension arcs (22) by means of rods (not shown).

[0042] It is noteworthy that the deployment remote control (17) allows the operator to perform the deployment sequence of the on-board virtual reality room (1) of the transport configuration illustrated in [Fig.2] then the initial deployment phase illustrated in [Fig.3] then the advanced deployment phase illustrated in [Fig.4] then the operational configuration illustrated in [Fig.[l], deployment sequence which is broken down by lowering the central telescopic platform (6), lowering the two folding side platforms (7), putting the twelve servo-controlled leveling jacks (13) into position, leveling by means of the horizontal servo-control device (14), raising the four telescopic columns (8), hoisting and positioning the source box (26) by means of the rotary hoist (11), deploying the four deployable segments (18) by means of the two winches (25), unrolling and tensioning the rollable immersive projection screen (33) by means of the screen magazine drum (34) and the tension winches (35). .

[0043] In a conventional manner, like a theatre curtain, the tension winches (35) are installed on the rail in eight support-tension arcs (22), their cables running in the thickness of the rail in eight support-tension arcs (22) to the screen magazine drum (34) thus allowing the rollable immersive projection screen (33) to be pulled, to give it its cylindrical shape and to be put under tension up to the operating configuration as illustrated on [Fig.1].

[0044] Advantageously, visitors can control the immersive experience by means of the interactive immersive control device (32).

[0045] Advantageously, the roll-up immersive projection screen (33) is made of a fabric which has the characteristics of being robust, with a low degree of elasticity, and exhibits a good quality albedo.

[0046] In a conventional manner, the folding sequence from the operational configuration to the transport configuration is exactly the reverse of the deployment sequence from the transport configuration to the operational configuration.

[0047] Advantageously, such a system makes it possible to offer an immersive experience to visitors in an easily transportable cylindrical embedded virtual reality room which can be installed by a small technical team, which offers a good perception of immersion, a free movement visiting space, an attractive space promoting the shared immersive experience.
