Description

Technology Field

[0001] The present invention relates to a performance production technology for maximizing audience immersion and concentration in performance venues, event halls, outdoor stages, etc. More specifically, it relates to a mobile signage-based performance production system configured such that multiple mobile signage devices, each equipped with a signage screen on an Automated Guided Vehicle (AGV) or an Autonomous Mobile Robot (AMR), move within a space to output group video content, and a performance in which an actual celebrity or performer appears on one of the devices is possible. Background Technology

[0002] LED display boards, projection screens, and fixed displays are utilized in existing performance venues to convey performance information or serve as visual effect elements for stage production. These fixed display devices are installed permanently on the stage background or the front wall and perform functions such as outputting background video, providing subtitles, and transmitting production effects.

[0003] However, since such fixed display devices have a fixed installation location, they impose restrictions on the position and direction of performances and are not suitable for movement-based staging designed to utilize the performance space three-dimensionally. In particular, in venues such as stages, festivals, and street performances viewed from multiple directions, information delivery to some audience members is limited, and visual immersion is diminished.

[0004] Recently, there has been an increasing demand for mobile displays or signage devices as production tools on performance stages. Mobile signage devices can move freely on and off the stage to output information relevant to the performance content in real time and create visual effects tailored to the movements of performers or the production team, making them advantageous for ensuring flexibility in stage configuration. Nevertheless, attempts to directly utilize mobile signage devices in performance production are currently limited, and related technology remains insufficient. Prior art literature

The present invention may be embodied in various different forms and is not limited to the embodiments described herein. In the drawings, parts unrelated to the explanation have been omitted to clearly explain the present invention, and the same reference numerals have been used for identical or similar components throughout the specification.

[0027] The words and terms used in this specification and claims are not limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention in accordance with the principles by which the inventor defines terms and concepts to best describe his invention.

[0028] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings correspond to preferred embodiments of the present invention and do not represent all technical concepts of the present invention; thus, various equivalents and modifications that may replace such configurations may exist at the time of filing the present invention.

[0029] In this specification, terms such as “comprising” or “having” are intended to describe the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should not be understood as precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0030] Hereinafter, preferred embodiments of the present invention will be described in detail in conjunction with the attached drawings.

[0031] FIG. 1 is an illustrative diagram for explaining the main configuration of a mobile signage device for performance assistance according to the present invention.

[0032] Referring to FIG. 1, a mobile signage device (100) for performance assistance according to the present invention may be implemented by including a communication module (110), a monitor (115), a proximity sensor (120), a LiDAR sensor (125), an illuminance sensor (130), a storage module (135), a camera module (140), a battery module (145), a signage screen module (150), a stand structure (155), a movement module (160), and a control module (400).

[0033] The control module (400) includes a main controller comprising a microcontroller (MCU) or a system-on-chip (SoC), integrates and analyzes information collected from sensor modules (120, 125, 130, 140), generates a real-time driving path, and controls the movement module (160). For example, the control module (400) executes a Simultaneous Localization and Mapping (SLAM) algorithm to create a map of the movement space and utilizes it as a reference coordinate system for autonomous driving. Additionally, the control module (400) precisely controls movements such as turning radius, path correction, and corner deceleration through a plurality of motion control algorithms. The control module (400) is linked with a Wi-Fi or Bluetooth-based smartphone app via a communication module (110) and provides functions for remote operation, reservation settings, and real-time monitoring.

[0034] The sensor module (120, 125, 130, 140) may include various sensor systems for recognizing the environment of the moving space and determining an autonomous driving path. The sensor module (120, 125, 130, 140) may be mounted on various parts, such as the front, top surface, or side of the mobile signage device (100) for performance assistance.

[0035] The LiDAR sensor (125) measures the distance to surrounding obstacles in real time to create a precise map of the indoor space and enables autonomous SLAM of the robot's position. The proximity sensor (120) is used for short-range obstacle detection to prevent collisions with objects such as walls or furniture. The vision sensor can identify people, pets, or specific restricted areas through object recognition based on the camera module (140).

[0036] The light sensor (130) enables the mobile signage device (100) for performance assistance to detect the brightness of the surrounding environment in real time while driving and to perform controls such as automatic adjustment of display brightness, improvement of driving safety, and enhancement of user responsiveness depending on the situation. For example, automatic adjustment of display brightness can optimize visibility and glare by automatically adjusting the brightness of the signage display according to changes in brightness within the performance venue (e.g., blackout, lighting change, etc.). Improvement of driving safety can be configured to increase detection sensitivity in conjunction with other sensors or output an emergency lighting signal when the ambient light is low (e.g., backstage, shaded area). Enhancement of user responsiveness can also be utilized as a trigger sensor for specific performance effects (e.g., outputting content that reacts to changes in brightness).

[0037] The control module (400) performs automatic display brightness control according to changes in illumination within the performance hall, driving safety control, content linkage control, and energy efficiency control operations based on data received from sensor modules (120, 125, 130, 140) including an illumination sensor. The control module (400) analyzes the value of the illumination sensor (130) according to changes in lighting within the performance hall (e.g., blackout, change in stage lighting, etc.) and automatically adjusts the brightness of the signage display upward or downward to ensure visibility and prevent glare for the audience.

[0038] When the output of the illuminance sensor (130) is detected to be below a set threshold (dark environment), the control module (400) increases the detection sensitivity of the proximity sensor (120) and the lidar sensor (125) or activates an emergency lighting signal output, such as a warning light or warning sound, to prevent the risk of collision in advance. When the illuminance change matches a specific condition (e.g., a change in stage brightness), the control module (400) executes an illuminance-based trigger event, such as switching display content or outputting a special effect. By automatically optimizing the display brightness according to the illuminance environment, the control module (400) can reduce unnecessary power consumption and contribute to extending battery life and controlling heat generation. The control module (400) uses data input from the sensor modules (120, 125, 130, 140) to search for a driving path, perform precision braking, search for an area, avoid obstacles, and automatically correct the path.

[0039] The control module (400) analyzes data input from the camera module (140) to extract feature information corresponding to a person, and based thereon determines the user's location, direction, distance, etc., and enables correction of the viewing angle and transmission of content customized for the viewer. Feature information corresponding to a person includes age, gender, etc.

[0040] The storage module (135) may store data including a computer program, code, instructions, or a combination of one or more of these. The storage module (135) may include content, driving path search, precision braking, area search, an algorithm for avoiding obstacles and automatically correcting the path, a motion control algorithm for a moving object, an image quality improvement algorithm, and an automatic saturation correction algorithm.

[0041] Algorithms for finding a driving path, precise braking, area search, avoiding obstacles, and automatically correcting the path can be implemented, for example, as SLAM algorithms. The SLAM algorithm collects sensor data, estimates in real time where a moving vehicle is located within the current environment based on input data collected from the sensors, creates a 2D or 3D environment map of the recognized surrounding space based on the movement trajectory and sensor data to date, improves the accuracy of the entire map by aligning past information with current location information to correct accumulated position errors when the vehicle re-enters a previously visited place, calculates an optimal driving path on the created map, and prevents collisions by recalculating the path when obstacles or dynamic objects are detected.

[0042] The battery module (145) supplies operating power to the entire device and may be configured to include a lithium-ion battery pack and a charge state sensor. The module may be implemented in the form of a modular hydraulic power pack and may include, for example, a lithium iron phosphate battery that outputs a DC voltage of 80V or higher and a three-phase induction AC motor whose speed, torque, and operation are controlled by a motor controller. The control module (400) monitors the remaining battery level in real time through the charge state sensor and, when the remaining level is detected to be below a set threshold, determines that the automatic return condition is satisfied and controls the device to automatically move to a charging docking station and perform charging.

[0043] The signage screen module (150) is implemented as a display of 85 to 100 inches and can be displayed in a sufficient size so that a virtual human or a person in an advertisement can be seen at a 1:1 scale with a viewer in real space. In addition to a standard display, a glasses-free stereoscopic display, a polarized stereoscopic display, etc., can be applied to the display.

[0044] Glasses-free 3D displays create a sense of depth without glasses by attaching special films or grids to the TV screen to deliver different images to the left and right eyes, with the effect maximized when the viewer is positioned in a specific location. Polarized 3D displays play content separated by scanlines on a screen equipped with different polarizing films, allowing viewers to enjoy 3D images by receiving different images in their left and right eyes through dedicated polarizing glasses. This enables characters or content within the screen to be displayed more three-dimensionally, allowing for a more realistic experience when moving.

[0045] The stand structure (155) is configured to allow an actual artist (performer) to board the mobile signage device (100) for performance assistance, and to cover the actual artist (performer) so that they are not visible from the outside. The stand structure (155) can be implemented in a box type or in various other shapes such as a cylinder.

[0046] The monitor (115) is installed inside the stand structure (155) and allows the actual artist (performer) who is inside the mobile signage device (100) for performance assistance to check the external situation or the appearance signal input from the performance console, remote control device, or control module (400).

[0047] The movement module (160) is equipped with independently driven wheels and motors on opposite sides, enabling linear movement, rotation, and turning in place. Each wheel may be equipped with, for example, a suspension structure to maintain stable traction on various ground conditions, such as a rug (door threshold), carpet, or tile. The movement module (160) includes a bumper or shock absorber to protect the signage screen module (150) in the event of a collision, and can adjust its speed based on signals from the sensor modules (120, 125, 130, 140).

[0048] FIG. 2 is an illustrative diagram for explaining the exterior of a mobile signage device for performance assistance according to the present invention, FIG. 3 is an illustrative diagram for explaining the mobile signage device for performance assistance shown in FIG. 2, and FIG. 4 is an illustrative diagram for explaining the movement module of the mobile signage device for performance assistance shown in FIG. 2.

[0049] First, referring to FIG. 2, the mobile signage device (100) for performance assistance according to the present invention is implemented in an overall box shape, and a space is provided for an actual artist (performer) to be mounted inside. The mobile signage device (100) for performance assistance is implemented as an integrated autonomous mobile robot (AMR) or an automated guided vehicle (AGV) to realize mechanical automation of performance production.

[0050] The mobile signage device (100) for performance assistance is equipped with a display of 85 to 100 inches on the front, and can be displayed in a sufficient size so that a virtual human or a person in an advertisement can be seen at a 1:1 scale with the viewer in the actual space. The mobile signage device (100) for performance assistance can change the display content in real time by receiving a content switching command from a performance production system, such as a performance console or a remote control device.

[0051] Referring to FIG. 3, the mobile signage device (100) for performance assistance according to the present invention has shields (211, 212) installed on both sides of the signage screen module (150) and the stand structure (155). The stand structure (155) is fixedly installed on the mobile module (160) and firmly supports the signage screen module (150) and the shields (211, 212). A monitor (221) is installed inside the shield (211). The monitor (221) can be implemented as various electronic devices, such as a camcorder or an LCD display device.

[0052] Referring to FIG. 4, the movement module (160) of the mobile signage device (100) for performance assistance according to the present invention includes independently driveable wheels (162) on both opposing sides and 4-way auxiliary ball casters (161, 163), enabling linear movement, rotation, and rotation in place. The 4-way auxiliary ball casters (161, 163) are positioned at the four lower corners or on the front, rear, left, and right sides of the movement module (160), providing mechanical balance and auxiliary support in addition to the drive wheel (162) which serves as the center of rotation, while enabling stable movement when changing direction or driving on uneven surfaces.

[0053] FIGS. 5 to 7 are illustrative diagrams for explaining examples of use of a mobile signage device for performance assistance according to the present invention.

[0054] Multiple mobile signage devices (411, 412, 413) for supporting performances can operate simultaneously in various directions or areas of the performance stage. This enables the production of advanced visual effects for the performance and maximizes audience immersion and a sense of presence. For example, it is possible for multiple mobile signage devices (411, 412, 413) for supporting performances to output synchronized content or display mutually different information to provide a split-performance effect.

[0055] Multiple mobile signage devices (411, 412, 413) for supporting performances may each display a performance stage video of one artist (performer) on a signage screen, or may display performance stage videos of multiple artists (performers) on each of the multiple mobile signage devices (411, 412, 413) for supporting performances. For example, in the case of a group of three idols, the performance stage video of each member may be displayed in a 1:1 correspondence with the multiple mobile signage devices (411, 412, 413) for supporting performances. As another example, in the case of a group of six idols, the performance stage video of two members may be displayed on a single mobile signage device for supporting performances.

[0056] Multiple mobile signage devices for performance assistance (411, 412, 413) may be designed to accommodate at least one person or two people. This allows the mobile signage devices for performance assistance to go beyond simple display and be used for effects such as the appearance of actual artists (performers), real-time performances, and surprise appearance events.

[0057] Referring to Figures 6 and 7, for example, during a performance, a mobile signage device for performance support moves to the center of the stage, and then an actual artist appears from inside, thereby creating an immersive effect where the screen and the physical object merge. This function can be utilized as a core technology for implementing immersive performance content systems, audience-customized stage production, and multi-channel offline performance UX in the future performance and entertainment industry.

[0058] Although embodiments of the present invention have been described, the spirit of the present invention is not limited by the embodiments presented in this specification. Those skilled in the art who understand the spirit of the present invention may easily propose other embodiments within the scope of the same spirit by adding, changing, deleting, or adding components, and such are also to be considered to be included within the spirit of the present invention.
