Description

AN ENTERTAINMENT SYSTEM AND METHOD OF CONSTRUCTION

FIELD OF THE INVENTION The present invention relates to an entertainment system, particularly to a mobile stage or system for the display of virtual image that is designed for easy transportation. The system comprises of a stage with a screen component for projection of pepper's ghost image on such screen. The invention relates more particularly to the system and method of constructing the improved mobile entertainment system/stage along with other accessories such as herein described.

BACKGROUND AND PRIOR ART

With more and more development in the technology, people are not restricted to create the holographic images inside the holographic studios alone. They want to explore the out-door locations and apply the holographic technology. For example, a theatre play or a social awareness street play, election campaign or any other music/ dance program that is being displayed using this technology cannot be happening only in the studios. In that case, motion picture recording devices are used in the sites but it is not possible to move a motion picture studio as it creates problem in the finishing process.

Hence to cater the need of any outdoor shooting or any live program using this technology, the present invention discloses a portable mobile holographic projection system that can be easily transported to any place. The present invention aims facilitate live programs or any other onsite plays where virtual image needs to be captures and displayed using holographic technology.

US8269900 entitled "Mobile studio" discloses a mobile studio for producing video and audio content which includes a vehicle having a body mounted on a chassis. The mobile studio is like a conventional studio set up in a vehicle to be used for the capturing and projection of the virtual/ pepper's ghost image that can be used in a remote locations. Conventional studio of the holographic apparatus or system has a transparent screen where the image is projected that has many drawbacks. Apart from the screen component, the entire mobile studio system has a different arrangement in the present invention. US2007/098368 entitled "Mobile recording studio system" discloses a recording system including a modular enclosure within which an individual or a group can perform with an environment control system that controls the environment within the modular enclosure during a performance that takes place in the enclosure. It is complete arrangement with audio recording device, video recording device, playback system, digital signal processing etc. But this does not aid in creating holographic image or projection with the disclosed arrangement.

US4771305 entitled "Method and apparatus for commercial photography" discloses a mobile studio for photography that includes a studio chamber enclosure formed by a floor, a ceiling, spaced opposite outer side walls and spaced outer front and rear end walls in a movable vehicle. The studio chamber further includes plurality of functional areas like portrait subject seating area. This system gives a natural background in the portrait being taken. But this system is restricted only to the conventional photography and the output of the same but not in relation with the pepper's ghost image projection which is a cumbersome process.

SUMMARY OF THE INVENTION The present invention basically tries to amalgamate three different types of genres of performing arts- namely theatre with live actors, projection screens for displaying documentary and feature films and a separate space for displaying virtual images which comprise the main components of the entertainment system. This system can be mounted on a transport means such as a suitable vehicle or truck which will be used as a mobile entertainment system.

A system of a mobile stage includes a screen component for the purpose of producing an enhanced Pepper's ghost image comprising of a rectangular shipping container with parts cut out for the speakers, technician doorways, front facing and back facing parts of the stage; two faux-walls made from wood on either side of the stage; the said faux-walls creating small spaces on either sides of the stage for uninterrupted power supply; the said spaces housing the technician controls for the lighting, the media players and acoustic controls. The novel foil/ screen component further comprises of a polymer substrate coated with silicon dioxide in 10 - 100 nm where in the projected image forms on the coated surface. The obtained screen has enhanced properties that supports the mobile stage and can be used in any kind of atmospheres. The fibrous glass coating given makes the screen hydrophobic which helps in keeping the screen free from dust particles and moisture content. It is also fire resistant, flexible and can be re-used.

A projector is placed on the top which can be lifted one foot higher by the use of hydraulic pumps. The projector projects a virtual image on the novel foil/ screen component directly through lens shifting and not by key stoning which will be placed in the pathway between the projector and the semi-reflective screen.

The shutter is sealed by the use of rubber to reduce the amount of dust from entering. The said shutter also increases the viewing angle of the viewer. A semi-reflective material, such as glass is fitted into the stage after being fitted into a metal frame by the use of a rubber, which in turn is fitted into the container at an angle of 45°. The above said frame holding the semi-reflective material is fitted with 'L' shape protrusions, within which a rubber bar is placed, to reinforce the glass during transport. The semi-reflective glass and the frame are suspended from the roof of the stage by the use of springs.

The rear part of the stage consists of two flaps wherein one flap has its hinges on the top and other hinges on the bottom, both are connected via mechanical winches so that the flaps can be lowered or raised accordingly. The flap with its hinges is attached to a black cloth and curtains along its perimeter on the top and contains the lights required to light the curtains in the bottom.

The entire stage can be fitted onto a standard 20-feet long truck and be transported by road wherein the stage is covered with plywood and black cloth so as to absorb any ambient light directed into the stage. The curtains are lit up behind the virtual image projected by the projector on the semi-reflective screen, so as to add depth and hence produce a 3-D effect to the viewer. One of the faux walls will include a slit, for the technician to monitor the proceedings without leaving the small room, on the side of the stage. Other aspects and example embodiments are provided in the drawings and the detailed description that follows.

The invention has been represented where appropriate by conventional in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein. DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the exemplary embodiment(s) of the invention. Before describing in detail embodiments that are in accordance with the present disclosure, it should be observed that the embodiments reside primarily in combinations of process steps and components of product.

In this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, product, method, article, device or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, product, method, article, device, or apparatus. An element proceeded by "comprises ...a" does not, without more constraints, preclude the existence of additional identical elements in the process, product, method, article, device or apparatus that comprises the element. Any embodiment described herein is not necessarily to be construed as preferred or advantageous over other embodiments. All of the embodiments described in this detailed description are illustrative, and provided to enable persons skilled in the art to make or use the disclosure and not to limit the scope of the disclosure, which is defined by the claims. It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention. Thus it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.

In the following description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present method of operation and construction of a mobile stage. It will be apparent, however, to one skilled in the art that the present invention can be practiced without these specific details. In other instances, structures and devices are shown in block diagram form only in order to avoid obscuring the present invention.

Figure 1 shows front and rear view of a rectangular box, such as a shipping container, and highlights where it has to be cut to form a stage including exhaust 1, rear wings 2, entry for technicians 3, projector 10, hydraulic lift 9, speakers 5 and front shutter 6. The mobile stage can be constructed into the body of a shipping container by cutting parts of it, for the rear wings 2, the front shutter 6, the space 5, exhausts 1 and entry way for technicians 3. In another embodiment, the mobile stage shall be fitted with an electric shutter instead of a conventional mechanical shutter 6, which will be calibrated to seal the container tightly, by the use of rubber pads. The use of rubber to seal the container shutter is essential, as it prevents minute spaces from being formed, and hence disallows dust from the entering the mobile stage. The mobile stage, which is made of mild-steel, will be fitted with wood, so as to cushion any equipment placed within its confinement. This wood will be covered with a dark material such as black carpet 12 (as shown in Figure 4), to absorb any ambient light, during a show. The carpet also attracts any of the dust that may enter the stage, which can be easily cleaned by the use of a vacuum cleaner.

Space 5 will be allowed on either parts of the shipping container, for housing the other material such as speakers, media players, acoustic mixers, generators, batteries and uninterrupted power supplies. It is, from within these spaces, a stage technician may operate the whole show. The spaces will be blocked off from the rest of the container by the use of faux-wood walls.

Figure 2 shows rear design of the rectangular container box showing the rear flap with its hinges on the bottom and the rear flap with the hinges on the top. Before the beginning of a show, the truck's rear wings 7 and 8 which are made out of a lighter material than mild-steel, will have to be unfolded as referred in the figure. The outer wing 7 with its hinges on the bottom will collapse onto the bottom, and the inner wing 8 with its hinges on the top, will rise onto the top. A black cloth and curtains will already be attached to the inner wing 8, so when the inner wing begins to raise, the black cloth and curtains will rise with it. Hence with an outer black cloth covering the perimeter of the opened wings, the stage is virtually extended. Once the show is completed, the top wing is brought inwards and then the bottom wing is brought inwards to seal the truck. The inherent advantage of using two wings over just one wing is that it reduces the amount of air that enters into the stage, and hence reduces the amount of dust.

Figure 3 shows the placement of the projector with its the hydraulic lift and the lens of the projector in the stage. With reference to figure 3 and figure 4 which illustrates the placement of black carpet placed all around the stage to absorb light and a semi-reflective surface, the projector will be housed within a hydraulic lift 9 which will allow the projector 10 to beam the image directly On the reflective screen 14 without the need for key stoning as the angle of the lens 11 may be shifted. This image will hence fall on the semi-reflective surface 13, placed at an angle a. The projector will be placed at the top of the container or the stage, and will be lifted at the time of the show by the use of hydraulic lifts 9. These lifts will raise the projector one foot above the roof to increase the distance between it and the reflective screen 14. This increase in space will accommodate more powerful projectors than the ones placed one foot below and hence improve the quality of the image vastly.

With reference to Figure 5, the semi-reflective surface 13 in the current case a semi- reflective glass 21 which is placed at an angle of 45°. This is done, by first placing the semi- reflective glass 21 in a steel frame 17. The steel frame's inside is lined with rubber, and slits are made within it, to allow the glass to slide in easily. Once the glass is securely fitted into the steel frame, it is brought into the containers, and the frame containing the glass will be fitted in at an angle of 45°.

With reference to Figure 5 and Figure 6, 'L' shaped protrusions 19 are affixed on to the centre part of either side of the frame via screws 18, which houses the semi-reflective surface. After the semi-reflective surface is fitted into its frame and the stage is about to be moved, a rubber bar 20 is placed between these grooves to reinforce the glass. This rubber bar will be removed at the time of a show. By lighting the curtains 16, and real objects on the stage using low heat producing lights such as LED spot lights, and by projecting a virtual image on the semi-reflective screen, it is possible to create a three dimensional effect to the viewer 15.

Yet another embodiments of the invention has been introduced to enhance the visual aspect of the three dimensional figure. This alternative method will work best on a 40 feet stage as shown in Figure 7. By placing a platform 23 in front of the stage it is possible to extend the stage forward and increase the depth of the image. This stage may be utilised by real performers and artists 22 (as referred in Figure 9), which will allow the viewer 15 to perceive further depth of virtual image formed on the semi-reflective surface 13. Figure 8 shows how artists 22 perform on the platform along with the stage for virtual image creation. The whole set up is arranged in a transportable truck illustrating the objective of the invention.

With reference to Figure 9, on either sides of the semi -reflective screen 13, back projection screens 24 may be placed. Projectors 10 placed behind these screens will beam images onto the projection screens. These screens will enhance the performance of the artists on the stage in front of the screens on the platform 23. An antenna 25 may be placed on top of the mobile stage, so as to access images live from a remote location.

In one of the embodiment, the system does not require the reflective screen placed at the bottom to reflect off the image formed on it. It comprises of a stage 101, a rear projector device 104 and a semi-reflective screen surface 103 which is applied with an adhesive to a glass or polycarbonate surface, and placed at an angle of 90° to the stage surface 102. The rear projection device 104 is placed on the roof of the stage 101 and is adjusted into its precise position with mechanical or hydraulic support. This rear projection device is placed low enough to not affect the image, and also to appear concealed to the viewer. Figure 10 shows the semi-reflective surface 103 placed at an angle of 90° to the stage surface 102 such that a space of at least 10-20 feet is allowed behind polycarbonate surface, which allows the viewer to perceive third dimensional depth. This 'z' depth 110 is created physically and virtually by designing the background through selective positioning of lights and props 111 behind the semi-reflective screen 103.

In another embodiment, 'z' depth 110 is created by placing real objects or persons 115 behind the screen 103 and lights 111 them up as shown in figure. The viewer perceives the real and virtual objects together, which would give him a perception that the virtual image 120 is alongside a real image and is therefore also real.

The background design will consist of created shadow areas that will create a separation between the reflecting surface and the background, thereby creating the virtual 'z' depth according to yet another embodiment. This component can be used in a conventional stage performance and also it is compatible with mobile stage. The accompanying drawings describe the invention in detail.

The positioning of the projection areas is achieved through lens adjustment and projector positioning as opposed to key-stoning. The use of the key-stone reduces the luminosity of the projector, hence by substituting it by lens adjustment, allows the projection device to completely utilize its maximum luminosity.

In the case of a glass surface, the standard length may be much lesser than that, which is desired. To compensate for which, the glass surfaces may be attached together at the edge. The slight disparity at the edge may be covered by applying a coating of the flexible polymer film on it.

Figure 11 shows front view of a transportable truck closed using electric shutter 6 where the whole virtual imaging studio is set up. Figure 12 shows front view of a transportable truck that is opened with the stage extended by a platform 23. The interior of the stage shows the placement of carpet 12 along with the semi reflective screen 13. Figure 13 shows the side vie of the transportable truck with a glimpse of front and rear side of the stage.

Further, the following additional details about the construction of the truck forming different embodiments of the present invention are not depicted in the drawings, but explained to detail the nuances of the invention, as follows. A small slit will be made on one of the faux- wood walls, which will have a mechanism to open and close. This will allow the technician to monitor the performances occurring on the stage, without exiting the small space; and separate pipes will be laid within the wooded walls of the stage, for the purposes of electrical wiring, video cabling and audio cabling. These pipes will be independent for each of these cables, and will be completely electrically shielded, so as to not allow any electrical interference between them.

In yet another embodiment, alternate provision can be made in the system as follows. The semi-reflective surface can be substituted with a polymer instead of glass; the material that is used to make the rectangular box, which houses the stage can be made of any metal, alloy or hard plastic such as carbon fibre; the two rear wings can be made up of any metal, alloy or hard plastic, as long as it is of a lighter material than the material used in the construction of the rectangular box, which houses the stage; the projector may be placed within the stage, and the image may be directed onto the reflective screen, by the use of reflective media such as mirrors or quartz crystals; the projector, housed in the hydraulic lift, may be placed in the bottom, and the reflective screen on the top; the semi-reflective screen can be placed within the rectangular box, in any angle between Γ and 89°; the shutter may be replaced with a permanent non-reflective screen; the space of the side may be removed, and the components such as speakers, media players, generators, uninterrupted power supplies, batteries and audio mixers may be placed at the top of the rectangular box; the dimensions of the rectangular box may be greater of lesser than that of a shipping container; slits in the faux wooden walls may be made in both the walls, and none at all; an antenna may be placed on top of the container, and fixed there for the requirement of live broadcasting or streaming of media content; the two rear wings may be replaced with a permanent rectangular box, protruding from the side of the rectangular box, which houses the mobile stage; the rectangular box may include hooks and holes at its bottom for fixing the rectangular box into the truck; the rectangular box may include hooks and holes at the top, to make it easier for cranes to lift the box; the rubber bar, used to reinforce the glass can be replaced with any other soft but firm material; the controls for the show can be done remotely, by the use of wireless connections, and does not require the technician to be within the rectangular box; the projector may be permanently fixed in an iron box, at a height of 1 foot above the container, and would not require the use of hydraulic lifts; the generator, battery and uninterrupted power supplies may be removed from within the body of the rectangular box, and be brought in straight from the vehicle, which is transporting the stage; and the two spaces on the either side of the container may be avoided, with the speakers placed on top of the truck, the power supply being brought in straight from the vehicle transporting the stage and media player maybe controlled remotely thereby widening or making full use of the stage.

The mobile stage will be constructed using a hard framework made from, but not exclusively, of metal. It can be of a standard length of 40 feet width of a normal shipping container or any desirable size, so as to allow it to be transported across the nation. The mobile stage will be a hollow rectangular box, made from a hard material. It could also be carved out of a regular shipping container of 40 feet length or any length depending on the requirement. Small spaces on either sides of this rectangular box will be occupied for the purposes of placing electrical fixtures, speakers, generators, uninterrupted power supplies and batteries in case of back up. These small spaces must be blocked off from the rest of the rectangular box. Once the truck carrying the mobile stage arrives at its venue, stage assistants will place external battery operated lights and the front door of the container which is powered by winches, opens to the public. Stage artistes, be it of the singing-dancing kind or stand up comedian kind- will mount the stage created by the opened door of the container and commence their performance.

At the same time the rear door also opens and stage assistants get busy building a box like structure behind which accommodates lights and a stage needed to create a depth of field for the virtual image that will be displayed. After a short live performance, the artists leave the stage and a documentary film is screened on two screens to the right and left of the stage. These are powered by back lit projectors placed inside the container. This could be followed by further live performances, after which time all the back projection screens open up on motorized rollers revealing a virtual stage powered by an additional projector placed upon the roof of the container. A virtual person materializes and makes a speech or a presentation. In this way the mobile stage handles all three types of presentations- live performances, film screenings and virtual avatars.

A small portion from the roof of the box shall be converted into a hydraulic lift, within which a projector will be housed. When a show is about to start, the hydraulic lift will lift the projector up and above the container, from which an image may be projected. As stated before, key stoning reduces the brightness of the image; however in this case one can simply shift the lens to attain a perfect image and forgo key stoning altogether. Another advantage in using this method is that projectors of high luminosity can be used in the form of short-throw projectors, instead of the ultra-short through projectors. The previous designs for shows used ultra-short throw projectors as they had a very short distance in which they had to project the image, i.e. throw distance. However, by placing the roof, the throw distance is hugely increased, and hence a short throw projector may be used. Short throw projectors have a much higher luminosity than an ultra-short throw projector, and hence would greatly improve the quality of the image.

The rectangular box, which would be modelled after a shipping container, will be of a relatively low width. Low width would reduce the depth of field and hence not produce a three-dimensional effect, which is required for Pepper's Ghost. For this, a unique system has been designed to increase the width of the box, at the time of a show. The backward facing part of the rectangular box will be fitted with two flaps, one placed within the other, with one's hinges placed on the top side and the other's on the bottom side of the box. When a show is about to begin and the stage has to be extended, by the use of mechanical winches, the flaps may be opened.

First the out flap is opened, and then the inner one is opened. By placing flaps both upper and lower sides, light is completely prevented from entering the box. The flaps will be made of an opaque material but is also light and durable, such as aluminium. The use of a lighter material than the rectangular box is so that the box can maintain its centre of gravity. One other advantage to having these flaps is that lights and curtains may be affixed at the beginning, and would not require further manual work, other than to simply adjust them, once the flaps have been unfolded. Between the two outward flaps, a non-porous material, like plastic will be used to cover up the perimeter. This is so that no light is allowed to enter the box, while at the same time not adding any extra weight to the container. After these are completed, the inner parts of the box are completely covered in dark material, to absorb any inward light, and not reflect any of it back. The virtual projection that occurs will be on a semi-reflective surface by the aforementioned projector via a reflective surface in the middle. The semi-reflective surface may be a polymer coated with a nano substrate of flexible glass silicon dioxide or hard semi reflective glass mirrors. The screen component comprises a polymer surface above which 10-100 nm substrate composition of silicon dioxide is deposited by a spray pump, preferably the silicon dioxide is in liquid form. The amount of coating of flexible glass substrate is decided depending on the intended effects.

The virtual image in this case is formed on the nano coated foil and not on the naked polymer surface. The screen/foil surface obtained is hydrophobic in nature which cannot hamper the quality of the image projected as it is easy to clean the dust particles deposited in the nano coated surface with a piece of wet sponge and cleaning spray. In another embodiment of the invention, the reflective properties of the screen/foil can be enhanced by silver or aluminium spray coatings. Such silver and aluminium is sprayed on atleast 5% of the screen/foil.

The glass coated polymer or hard reflective glass is placed at an angle between Γ and 89°, for the purposes of the viewing angle. By projecting onto a reflective screen on the bottom, which in turn reflects the image onto the semi reflective screen, it is possible to obtain a virtual image on the semi-reflective screen. By placing curtains and lights at the extended part of the stage, it is possible to generate depth of field, and hence give the virtual image a three-dimensional effect, thereby accomplishing a pepper's ghost on a mobile stage.

After the stage show is finished, the flaps may be closed, the projector may be brought down, the soft material may be placed in its groove to reinforce the glass and the shutter may be closed. Once these acts are accomplished, the stage may be easily moved to a new location via a truck.

Method of transporting hard semi reflective glass placed at an angle This invention also suggests means of placing a semi- reflective glass for the purposes of a mobile stage. One of the main problems of transporting glass, which is placed at an angle, is that the centre of gravity begins to act on the middle of the glass. This poses to be a major problem in transit, as due an uneven road, the vehicle may move up and down. When this happens, the upper and lower part of the glass comes closer to each other, and a large bulk of their weight falls on the centre of the glass. If the strain on the centre of the glass is too high i.e. if the upper and lower parts come too close together because of uneven roads, then the centre of the glass will experience enough stress to break it. To avoid this, the invention describes a unique sleeve, wherein the glass may be placed. A high tensile frame is placed into the rectangular box. The inner perimeter of the frame is fitted with rubber slots wherein the glass may fit. For the purposes of transport, two small outward grooves are made onto the frame at the point of centre of gravity. While the glass is being transported a soft material is placed between the two groves, to reinforce the glass, and not allow it to experience any stress while in motion. This soft material will be removed once a show begins.
