Grid platform combined control device and method for XR somatosensory large space

Abstract

The invention discloses an XR somatosensory large-space grid platform combined control device and method. The device is composed of a dynamic platform module, a driving control module, a central control module, a multi-sensory simulation system and a VR linkage module. The core characteristic is that a traditional large-area fixed partition plate is replaced by a grid system composed of at least two independent flat platforms. Each platform is provided with an independent servo drive and can shake, lift and vibrate. The multi-sensory system integrates water spraying, smell, temperature and wind power simulation. After a game instruction is received, a four-step control process of mode selection, parameter configuration, synchronous execution and feedback regulation is implemented. The system supports a'full sense mode '(enabling all dynamic and sensory simulations) and a'common mode' (providing a basic load bearing function as a static platform). The platform combination scheme supports multiple forms such as a single platform, double platforms and four platforms, and flexible switching is achieved through software parameters.

Description

Technical Field

[0001] This invention belongs to the fields of virtual reality (VR), augmented reality (AR), human-computer interaction control and mechatronics, and particularly relates to a combined control device and method for a large-space XR haptic grid platform. Background Technology

[0002] As XR technology, especially VR games, upgrades towards "full-sensory interaction," offline experience centers are gradually adopting medium to large-sized VR spaces, such as 6x6 meters, as standard configurations. Players are demanding unprecedented levels of realism and diversity in their experiences. However, current hardware innovation lags behind these experiential needs, particularly since most devices still employ the outdated "fixed structure + visual rendering" model, limiting innovation and diversity in the experience.

[0003] Among publicly available technical solutions, a typical implementation method is to use a "fixed partition + fixed-point mechanism" system. For example, a 6×6 meter "adventure-themed VR space" device on the market divides the space into multiple preset maze-shaped areas using 5-centimeter-thick wooden partitions, and installs fixed mechanisms within these areas, such as suspension bridges swaying along fixed tracks and elevators rising and falling at preset positions. This solution has a fixed structure and scene, and can only run specific full-sensory games customized for it. Due to its rigid physical isolation, it is incompatible with non-full-sensory VR games developed using mainstream engines such as Unity and Unreal Engine, leading to issues with the device's applicable scenarios and idle rate. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects of the prior art and provide a grid platform combination control device and method for XR somatosensory large space, so as to achieve: 1) breaking through the limitations of fixed structure and dynamically switching scenes; 2) significantly reducing the cost and cycle of scene updates; 3) integrating multi-sensory simulation to enhance immersion; 4) having strong game compatibility and scalability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A combined control device and method for a large-space XR motion-sensing grid platform.

[0007] The device mainly includes:

[0008] Dynamic Platform Module: The 6×6 meter XR immersive space is equally divided into 4 independent 3×3 meter flat load-bearing platforms (A / B / C / D). It adopts a high-strength steel frame and non-slip and wear-resistant panels, with a load-bearing capacity of ≥300kg and no fixed partitions.

[0009] Drive control module: Each platform is equipped with 3 servo motor groups (response delay ≤50ms), lifting unit (stroke 0-5 cm) and vibration sensor (accuracy ±0.1°) to support independent or combined motion control.

[0010] Central control module: As the core, it communicates with the drive control module and the multi-sensory system, and supports switching between "full-sensory mode" and "normal mode".

[0011] VR linkage module: Similar to the PICO4UEVR headset, it ensures millisecond-level synchronization (error ≤15ms) between the motion platform, multi-sensory effects and VR headset screen.

[0012] Multi-sensory simulation system: integrated inside the space, including: water spray system (micro-atomizing nozzles), odor system (5 odor storage tanks), heating system (electric heaters) and blowing system (adjustable speed fan).

[0013] The control method flow is as follows:

[0014] Mode Selection: The central control module receives control commands from the game server, selects "Full Sensory Mode" or "Normal Mode", and determines the required platform combination (single platform, dual platform combination or quad platform combination).

[0015] Parameter Configuration: Configure operating parameters for the activated platform and multi-sensory system based on the preset parameters of the selected scene.

[0016] Synchronous execution: Based on the platform combination scheme, precisely control the drive unit and the multi-sensory system to execute in coordination.

[0017] Single platform: Activate the target platform independently.

[0018] Dual Platforms: Activate the pairing platform to ensure that motion phase difference and multi-sensory trigger time difference are minimized.

[0019] Four platforms: Activate all platforms to ensure consistency of system parameters and platform flatness calibration.

[0020] Feedback adjustment: Data is collected in real time by sensors and fed back to the central control module to dynamically correct control parameters.

[0021] The present invention has the following beneficial effects:

[0022] 1. This device, through the combination of a flat grid platform and a multi-sensory system, can support more than 20 scenarios (such as 5 single-platform scenarios + 8 dual-platform scenarios + 7 quad-platform scenarios), fundamentally solving the problem of homogenization.

[0023] 2. The scene switching in this invention is achieved by adjusting software parameters only, with a cost close to zero and a debugging cycle of 15-30 minutes. The cost is reduced by more than 95% compared to existing technologies, and the efficiency is increased by hundreds of times, resulting in a revolutionary improvement in update cost and efficiency.

[0024] 3. In this invention, multi-sensory interaction (movement, water spray, smell, temperature, wind) is strictly synchronized with vision, improving the experience score and enhancing immersion.

[0025] 4. This invention supports dual-mode switching between full-sensory and ordinary non-full-sensory games, is compatible with mainstream game engines, expands the applicability of devices, reduces idle time, and has strong compatibility.

[0026] 5. This invention can increase the number of platforms to accommodate larger spaces and can also expand multi-sensory systems (such as adding foam sprayers or snowflake generators), resulting in good scalability, improved experience ratings, and enhanced immersion.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] A combined control device and method for an XR-enabled large-space grid platform, comprising:

[0034] 1. Assembly and Configuration Implementation Method of the Device

[0035] Hardware components:

[0036] (1) Site preparation and benchmark establishment:

[0037] In an indoor space with dimensions of at least 6.6m x 6.6m, define a 6m x 6m work area and use a laser level to calibrate the flatness of the floor, with the error controlled within ±2mm.

[0038] According to the design drawings, mark the center lines of four 3m x 3m grid platforms 1 (numbered A, B, C, and D) on the site.

[0039] (2) Installation of Dynamic Platform 1 Module:

[0040] Install platforms 1A to D in sequence according to the markings. Each platform 1 is constructed of a high-strength steel frame 2 (such as 50mm×50mm square steel), and a layer of anti-slip and wear-resistant composite material panel 3 is laid on it as the load-bearing surface.

[0041] The frame of platform 1 should maintain a 20mm gap with the adjacent platform 1 to ensure no physical contact or interference. Secure the frame of platform 1 to the pre-embedded parts in the ground or a dedicated base using heavy-duty bolts.

[0042] (3) Installation of drive control module:

[0043] Below each platform 1 (such as platform 1A), three sets of servo motors (such as Panasonic A6 series) and lifting push rods (travel 0-5 cm) are installed at equal intervals along its circumference.

[0044] High-precision vibration sensors are installed at key nodes of the platform 1 framework and wired to the interface of the drive control module.

[0045] Connect the power supply lines and data bus for the servo motors and sensors.

[0046] (4) Installation of the multi-sensory simulation system:

[0047] Water spray system: Eight micro-atomizing nozzles are equidistantly embedded below each carrier panel 3, and connected to independent solenoid valves and water supply lines.

[0048] Odor System: Five storage tanks with different odors (such as grass and wood smell, sand and soil smell, etc.) are placed in the control cabinet on the periphery of platform 1 and connected to the air outlet above platform 1 through air pipelines.

[0049] Heating system: An electric heater is installed at a height of about 0.5 meters above platforms 1A, B, C, and D.

[0050] Air blowing system: Multiple adjustable speed fans are installed in the four corners and around the top of the space.

[0051] (5) Central control module installation:

[0052] Install a central control module (such as an ARM-based industrial control computer) in the equipment room.

[0053] It can be connected to the drive control module, multi-sensory subsystem, and VR game server via Ethernet cable or CAN bus.

[0054] The configuration software interface includes a "Full Sensing Mode" and "Normal Mode" switch button, as well as parameter adjustment panels for each subsystem.

[0055] 2. Operational Examples of the Control Method

[0056] Example 1: Implementation of a "Rainforest Suspension Bridge" Scenario

[0057] Step 1: Mode Selection

[0058] Players wearing VR headsets start the "Rainforest Suspension Bridge" game. The central control module receives instructions from the server and identifies it as "Full Sensory Mode".

[0059] Step 2: Parameter Configuration

[0060] Based on the "Rainforest Suspension Bridge" scene configuration file, the system automatically sets:

[0061] Platform 1 combination: Single platform 1A.

[0062] Drive parameters: Platform 1A oscillation frequency 8Hz, amplitude ±12°.

[0063] Multi-sensory parameters: water spray mode is set to "rain" (0.2L / min), odor system releases "herbal scent" (0.3mg / m³), and air blowing system speed is adjusted to 4m / s.

[0064] Step 3: Execute synchronously

[0065] The central control module sends a control signal to the servo motor group 4 corresponding to platform A 1 via the bus to start the shaking.

[0066] At the same time, according to the preset delay parameters (millisecond level), the water supply solenoid valve, odor release valve, blower, and heater (not required in this scenario) are opened in sequence to ensure that the sensory experience is highly synchronized with the bridge crossing action in the VR image.

[0067] Step 4: Feedback Adjustment

[0068] The vibration sensor on platform A1 monitors the swaying amplitude in real time and feeds the data back to the central control module.

[0069] If the measured amplitude is 11.5°, which is lower than the preset 12°, the central control module will automatically fine-tune the motor drive current to compensate for the difference to the accurate value.

[0070] Example 2: Implementation of the "Doomsday Earthquake" Scenario

[0071] Step 1: Mode Selection

[0072] The central control module identifies it as "Full Sensing Mode".

[0073] Step 2: Parameter Configuration

[0074] The parameter configuration is as follows:

[0075] Platform 1 combination: All four platforms are fully open.

[0076] Drive parameters: All platforms 1 high-frequency vibration, frequency 20Hz, amplitude ±15°, accompanied by intermittent up and down changes (3cm up and down).

[0077] Multi-sensory parameters: All nozzles on platform 1 are in "splash" mode, the odor system releases a mixture of "sand and musty smell", the fan is fully turned on to simulate strong wind, and the heater is not activated.

[0078] Step 3: Execute synchronously

[0079] The system simultaneously activates the drives of four platforms 1 to ensure that vibration starts synchronously.

[0080] The multi-sensory system activates in a pre-programmed sequence to create synergistic environmental effects.

[0081] Step 4: Feedback Adjustment

[0082] Real-time monitoring of the flatness of each platform 1 (deviation controlled within ±2mm) ensures coordination between platforms 1.

[0083] If the vibration frequency of platform 1A is slightly faster, the system will adjust accordingly to ensure a consistent experience.

[0084] Example 3: Compatible with common VR games (such as "Beat Saber")

[0085] Step 1: Mode Selection

[0086] The central control module recognizes that the game has not started the full-sensory control protocol of this invention and automatically switches to normal mode.

[0087] Step 2: Parameter Configuration

[0088] All platform 1 drive units enter standby mode, and the multi-sensory system is completely shut down.

[0089] Step 3: Execute synchronously

[0090] Platform 1 serves only as a static 6×6 meter load-bearing surface and does not produce any motion or sensory effects.

[0091] Step 4: Feedback Adjustment

[0092] It monitors the player's location but does not trigger any feedback.

[0093] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
