[0002] This application claims the benefit of U.S. Provisional Patent Application Serial Nos. 63 / 456,373 and 63 / 456,363, both filed on March 31, 2023. The disclosure of the aforementioned provisional applications is incorporated herein by reference in its entirety. Technical Field

[0003] This application relates to an immersive projection system. Background Technology

[0004] HiVE (Hybrid Immersive Virtual Environment) utilizes fully immersive Cave Automated Virtual Environment (CAVE) technology for hands-on and collaborative learning. The world's first large-scale extended reality (X-Reality) hybrid classroom is a HiVE developed by the Hong Kong Polytechnic University for student education and training. This platform provides a virtual training environment that allows students to experience and practice work-related skills in realistic scenarios such as fire outbreaks, medical surgeries, and aircraft control rooms—scenes difficult to access in the real world. Summary of the Invention

[0005] One objective of this application is to overcome or substantially improve one or more disadvantages of the prior art, or at least to provide a useful alternative.

[0006] One or more embodiments combine existing classrooms (as an example of a pre-selected room) and a CAVE system into a hybrid learning facility to save installation space. Advantageously, this hybrid classroom allows teachers to easily conduct face-to-face and immersive teaching within a classroom environment, and switch between the two, to integrate virtual technology with traditional learning. This hybrid learning facility enables teachers to seamlessly switch between teaching modes from face-to-face lectures to immersive experiences, thereby achieving the goal of integrating virtual technology with regular learning.

[0007] One or more embodiments provide a novel six-sided CAVE-based technology that creates an extremely realistic, immersive environment to help students visualize abstract concepts and novel perspectives that cannot be shown in real-world settings. Furthermore, this technology allows students to engage with experiences they might not easily access in the real world, such as fire outbreaks, medical procedures, and aircraft control rooms. Theoretical, knowledge-based courses can be very difficult for students to understand. With the new six-sided CAVE technology, students can visualize abstract concepts that cannot be depicted in the real world. Additionally, this technology enables students to experience and participate in real-world scenarios, such as fire outbreaks, medical procedures, and aircraft control rooms, which are difficult to access in the real world.

[0016] In another embodiment, the interactive content performed on the image generator can be updated using motion capture information provided by the motion capture system as user input.

[0017] In another embodiment, the projection blending system warps and blends the images to be sent to the plurality of projectors so as to seamlessly merge the projected images of these projectors in the overlapping areas to which the images are projected. In yet another embodiment, the projection blending system also processes the warped and blended images based on the following rendering modes: namely, one type of blended image output for 2D mode and another type of blended image output for 3D mode.

[0018] In another embodiment, the image generator is configured such that interactive content performed on the image generator updates the generated interactive content using motion capture information provided by the motion capture system as user input.

Those skilled in the art will appreciate from this description that many other alternative implementations of these various elements can be utilized without departing from the scope of the invention, in addition to or instead of the examples provided herein.

[0048] As used in this article, the term "immersive room" refers to a room that can create an immersive or virtual reality experience for users within the room. A common method of providing immersion or virtual reality is to simulate a specific environment by projecting images onto the four or five surfaces of the immersive room.

[0049] Fully immersive projection system

[0050] Figure 1 This is a block diagram illustrating the main components of a fully immersive projection system according to one embodiment of this application. (Reference) Figure 1 The fully immersive projection system 100 includes an image generator 110, a projection blending system 120, a video processing system 130, an immersive room 150, an external audiovisual system 160, and an external control interface 170. The image generator can generate interactive content and render images to be displayed.

[0051] The immersive room 150 is equipped with: one or more projectors 155 that project images onto the ceiling, walls, or floor of the immersive room or any combination thereof; and a motion capture system 152.

[0052] In one embodiment, the immersive room 150 is also equipped with a surround sound system, at least one calibration camera 154, a supplemental visual aid system that receives input from an external audiovisual system 160, and other hardware devices or apparatus that receive input from an external control interface 170 for additional functions.

[0053] Figure 3 The image shows a scenario using a fully immersive projection system. Figure 3 This is a model diagram illustrating an immersive room 150 including a projector 155 and a perspective view of a projection cone within the immersive room 150, according to an embodiment of this application. Figure 2A and Figure 2B These are photographs taken within an immersive environment established according to one embodiment of this application, the photographs simulating bird's-eye views (…). Figure 2A ) and scenes inside the museum ( Figure 2B ).

[0054] Image generator

[0055] In one embodiment of this application, the image generator 110 is a computing workstation having at least a central processing unit (CPU), memory, a storage system, a set of graphics processing units (GPUs), a power supply unit (PSU), and a set of I / O interfaces. The image generator runs on a compatible operating system (OS) to process input signals, execute commands written in an application stored in the storage system, and render displays and sound output for a fully immersive projection system.

[0056] A configurable launcher application with a graphical user interface can be used to interface with the connected hardware device on the image generator 110 and launch commands in raw or executable format. The image generator 110 can be configured to render content in 2D or 3D mode.

[0057] When the content is set to render in 2D mode, the launcher application of the image generator 110 sends a command to set the projector to operate in 2D mode and another command to enable the 2D mode mapping profile to the projection warp and blending system; when the content is set to render in 3D mode, the launcher application sends a command to set the projector to operate in 3D mode and another command to enable the 3D mode mapping profile to the projection warp and blending system.

[0058] During the projection warping and blending process, a two-step process is employed to produce the desired immersive visual effect. First, interactive content on the image generator 110 is rendered and arranged based on the physical layout of the projection surface. Here, the projection surface is defined as a continuous surface facing the same direction within the immersive room. Then, blending is performed based on the rendered display layout, which is then further processed, rearranged, and assigned to each projector. When running in 2D mode with projection warping and blending, the entire pixel assigned to each projector is directly displayed by the projector. When running in 3D mode, the image generator 110 renders images for both the left and right eyes and arranges them side-by-side as the final output to be sent to the video processor.

[0059] Interactive content executed on image generator 110 can be updated using motion capture information provided by the motion capture system as user input. As a viewer equipped with a motion tracker moves around in the immersive room, the interactive content can be rendered from the viewer's perspective to provide a first-person view customized for that viewer. Alternatively, other input devices, such as controllers and haptic devices, can also be connected to the image generator as additional I / O devices to add additional interactive elements to the system.

[0060] Immersive projection system

[0061] The immersive projection system includes a plurality of projectors 155. In one embodiment, the plurality of projectors 155 includes a combination of ultra-short-throw (UST) projectors (i.e., projector throw ratio < 0.5:1) and short-throw (ST) projectors (i.e., projector throw ratio between 0.5 and 1:1), the projectors being strategically positioned outside the visible space of the system operating in a frontal projection manner. For projectors providing image projection to the front, back, left, right, and ceiling of the system, preferably, UST projectors or projectors equipped with UST lenses are used to minimize the required projection distance between the projector and the projection surface and to maximize the effective space, which is the space within the system where a viewer can move without encountering the projector's projection cone and casting shadows. For projectors providing image projection to the floor, preferably, ST projectors or projectors equipped with ST lenses are used.

[0062] In one embodiment of this application, at least one projector 155 is used to project an image onto the floor. The floor projector 155 is mounted on the top of the ceiling wall and projects onto the floor through an opening in the ceiling that is cut out in the same manner as a ceiling projector, such as... Figure 5 As shown in the figure. In another embodiment, at least one projector 155 is present for each projection side (front, back, left, right, ceiling, floor).

[0063] In one embodiment, when more than one projector is used on any given side of the system, the projected image output from each of the projectors 155 should have some overlapping area, so that effective projection distortion and blending can be achieved to seamlessly merge the projected images of these projectors 155.

[0064] In one embodiment, projector 155 is inserted into video processing system 130, which interfaces with image generator 110 via a layer of projection blending system 120 to generate frame-synchronized image signals to projector 155. Projector 155 can operate in either a normal 2D mode or a 3D stereoscopic mode. In 2D mode, the user can see a clear image with the naked eye. In 3D mode, projector 155 displays images alternately intended for the left or right eye, requiring the user to wear active stereoscopic 3D glasses synchronized with the display frequency of projector 155 to separate the alternating images for a clear stereoscopic view. During 3D mode, a 3D synchronization signal is required to synchronize the active stereoscopic 3D glasses with the displayed image from projector 155. This 3D synchronization signal can be generated by the video processing system when the 3D image is processed and created by the video processing system, or by any of the projectors connected to the video processing system when the 3D image is processed and created by projector 155 itself.

[0065] In another embodiment, multiple calibration cameras with fisheye lenses are strategically placed within the system and connected to the image generator 110 for projection warping and blending. To facilitate projection warping and blending, a camera-based calibration process is required by the projection warping and blending system. This calibration process utilizes a predefined 3D model of the room to calculate the UV mapping transformation of the real-world image captured by the calibration cameras. Projection warping and blending can then be achieved by applying the calculated UV mapping to the rendering buffer of the GPU of the image generator 110. UV mappings are calculated for both 2D and 3D modes, and the user can switch between 2D and 3D projection warping and blending by sending corresponding commands to the image generator 110.

[0066] Motion capture system

[0067] In one embodiment, to add interactivity to the system, multiple motion capture / sensing devices using optical or infrared light mechanisms are mounted at strategic locations within the system, near the ceiling, such as... Figure 5 As shown. Users / objects equipped with reflective markers forming predefined shapes or battery-powered trackers with pre-registered hardware identification numbers can be identified by the installed motion capture / sensing devices, allowing the motion capture system to parse the position / movement of the tracked subject (motion capture information). The motion capture information is streamed using a network or relevant public protocol to be used as input data by a fully immersive projection system to render interactive content on a display system.

[0068] Surround sound system

[0069] In one embodiment, a surround sound system is provided, mounted outside the display area to provide immersive spatial sound within the system. The surround sound system, consisting of at least one subwoofer for the front, left, right, and rear of the system and a set of speakers, is strategically positioned around the system to enhance the generated surround sound effect.

[0070] Figure 6 An immersive room equipped with a surround sound system and displaying a city night view, according to one embodiment of this application, is shown. References Figure 6 The projected image will be displayed on a wall with rectangular openings cut out, just large enough to mount the speakers of the surround sound system, allowing sound produced by the speakers to be projected into the room. The openings in the wall are covered with perforated panels painted the same color as the wall to minimize their impact on the system's immersion while allowing sufficient sound to pass through.

[0071] Immersive Room

[0072] Figure 3 A schematic diagram of a model used to display a stereoscopic view of immersive room 150 is shown.

[0073] Figure 3 The immersive room 150 depicted herein will be constructed within the original, existing structure of the room using partitions, i.e., drywall (or any other suitable material in the art). The drywall will divide the original structure of the room into an immersive room for the fully immersive projection system of this application and additional rooms / spaces for storage (e.g., hosting the image generator 110), concealing related hardware devices / equipment, or for any other purpose.

[0074] In addition to creating immersive environments, the immersive rooms in this application can also be used as regular classrooms, such as... Figure 4 As shown, this involves instructors delivering lectures face-to-face to the audience, as is common in a traditional classroom. Hybrid learning facilities enable teachers to seamlessly switch between face-to-face lectures and immersive experiences, thereby achieving the goal of integrating virtual technology with regular learning.

[0075] Figure 5 The projection system in the embodiments shown is installed behind a drywall (ceiling and floor projector) or installed in the immersive room 150 around the ceiling area. Figure 5 An opening is shown in the ceiling, through which a projector 155 mounted on the ceiling projects light onto the floor.

[0076] In one embodiment, the projection system, particularly the projector 155, is concealed behind a custom cover (for front, rear, left, and right wall projectors). Figure 7A A top view of a projector cover according to one embodiment of this application is shown. The custom-designed projector cover 700 is made of a rigid material (such as fiberglass) and has curved edges to minimize obstruction of projected light from a ceiling projector. Openings are formed in the projector cover to allow projected light to pass through.

[0077] Figure 7B This is a cross-sectional view of an immersive room having two projector covers 700 mounted on the ceiling, according to an embodiment of this application. The projector covers 700 extend from the ceiling and include a bottom wall and side walls.

[0078] Figure 8This is an image of the interior of an immersive room constructed according to one embodiment of this application. Two projector covers 700 are mounted on the ceiling of the immersive room 150, with openings formed in the side walls of the covers to allow projected light to pass through and be projected onto the front, back, left, or right walls of the immersive room. It can also be seen that the image is projected onto the ceiling, which includes the bottom and side walls of the projector covers 700. By cutting openings in the side walls of the projector covers 700, the impact of the openings on the image is minimized, and thus the user experience within the immersive room is enhanced.

[0079] Although drywall is used to form the immersive room 150 in the above embodiments, this application is not limited thereto. Any suitable material known to those skilled in the art can be used instead of drywall, including wood panels, PVC panels, metal panels, and plastic panels.

[0080] In one embodiment, a ceiling projector 155, configured to project light onto the ceiling, is mounted behind the left and right walls outside the interior space of the immersive room. An opening is cut into the wall for each projector to match the shape of the projected light cone, allowing light to pass through while minimizing the impact on immersion.

[0081] In one embodiment, each sidewall (i.e., the walls on the left and right sides of the immersive room 150) consists of two sections: a lower vertical section extending vertically upward from the floor of the immersive room; and an upper inclined section extending inclinedly from the upper edge of the lower vertical section toward the interior space of the immersive room. Figure 3 In one embodiment, the lower vertical section has a height of 2,100 mm, which is higher than a person's normal height, while the upper section, which slopes inward, has a height of 1,600 mm.

[0082] In one embodiment, a ceiling projector 155, configured to project light onto the ceiling, is mounted behind a wall at a height above a person's normal height and is oriented towards the ceiling or towards the ceiling and onto an inclined upper section on the opposite side. In the prior art where a vertically extending wall intersects with a horizontally extending ceiling, the image projected onto the area around the intersection is severely distorted. To address this deficiency, advanced and often more expensive projection systems are conventionally employed. By implementing this application, that is, by employing an inclined upper section, a relatively low-cost projection system can be used and the aforementioned distortion can be effectively overcome.

[0083] For each projector 155, an opening in the shape of the projector's light cone is cut into the lower section of the drywall to allow projected light to pass through. In one embodiment, the opening is positioned at a height above the average height of a person. The height of the opening on the vertical lower section can be greater than 180, 190, or 200 cm. With a considerable distance above the cut opening (e.g., 0 to 100 cm, preferably 1 to 80 cm, more preferably 5 to 60 cm, more preferably 10 to 50 cm, more preferably 20 to 40 cm), the upper section of the drywall is inclined inward at an angle closely matching the light path at the bottom of the projection cone. Figure 9 An example of this is shown in the figure.

[0084] By arranging the upper section to slope inward, the equipment for an immersive projection system or any other equipment can be installed in the space between the sloping upper section and the existing room's (e.g., a classroom) walls / ceiling, thereby enhancing the usability of the existing room's interior space.

[0085] In one embodiment, the entrance to the immersive room 150 is equipped with a hidden door, wherein the surface material of the hidden door facing the interior of the system matches the material used inside the room and is coated with the same surface coating.

[0086] The interior of the room is coated with a gray-toned surface paint that was specifically chosen to minimize internal reflections of the projector light while maintaining the vibrancy of the projected colors.

[0087] In one embodiment, the immersive room 150 is equipped with, for example... Figure 5 and Figure 10 The ventilation panel is shown. Other equipment or devices necessary to support the normal use of the system or for relevant regulatory requirements may be mounted behind the drywall, embedded in the drywall in a manner similar to surround sound system speakers, or placed inside the immersive room 150 in a location with minimal disturbance to the viewer. Examples of such equipment / devices include, but are not limited to, ventilation systems, light panels, carbon dioxide detectors, sprinklers, etc. Without sacrificing functionality, the appearance of the equipment / device may be designed to match the paint scheme of the immersive room 150.

[0088] Supplemental visual aids

[0089] Figure 11AThis is a cross-sectional view of an immersive room with an additional 2D projector mounted on an electric ceiling projector lift 400, according to one embodiment of this application. The additional 2D projector mounted on the electric ceiling projector lift 400 is concealed behind a drywall ceiling. In the non-operating state, the electric ceiling projector lift 400 is raised, with its bottom forming part of the drywall ceiling structure; while in the operating state, the projector located on the electric ceiling projector lift 400 is lowered by the lift, and the projector can project images onto a projection area on the front side. Activation is achieved by pressing a button on a control panel 1110 behind a hidden cabinet door within the system. An external audiovisual device can be connected to this supplemental visual aid system to provide the viewer with additional audiovisual content rendered in 2D.
