Modular Omnidirectional Floor Tiles for Virtual Stage Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video production systems constrain performers to move within a limited space, preventing them from walking off-camera or off-stage, limiting the realism and freedom of movement in filmed scenes.
Innovation Solution
A modular omnidirectional actuated floor comprising independently movable tiles that adjust to the movement of performers, allowing them to walk in any direction and at any speed while maintaining their position within the camera's view, synchronized with digital backgrounds and props to create a seamless virtual production environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If performers are constrained to a fixed platform, then the stage structure remains simple and stable, but the performers cannot walk for any distance or in any direction without moving off camera
Solution Approach 1:
The stage floor is divided into multiple independently controllable tiles or segments. Each tile can be individually actuated to move performers in different directions and at different speeds, enabling unrestricted movement while maintaining overall system manageability through modular control.
Solution Approach 2:
The stage transitions from a static fixed platform to a dynamic reconfigurable surface. The modular tiles can be actively adjusted in real-time to respond to performer movements, camera positions, and scene requirements, allowing the stage to adapt its configuration dynamically during performance.
2Area of stationary object
If the stage size is increased to allow greater movement, then performers can walk farther, but they may move off camera or off the stage
Solution Approach 1:
The system incorporates sensors and actuators that continuously monitor performer positions, camera locations, and stage configurations. This feedback loop enables real-time adjustments to tile movements and stage elements to keep performers within the desired filming area while maintaining the illusion of unlimited space.
Solution Approach 2:
The stage system can dynamically change parameters such as tile movement speed, direction, and magnitude based on real-time conditions. By adjusting these parameters, the system maintains reliable position control while allowing performers to effectively traverse unlimited distances through coordinated movement of stage elements.
3Ease of operation
If the floor is made modular with independently movable tiles, then performer movement freedom is enhanced, but the device complexity and control requirements increase
Solution Approach 1:
The modular tile design serves multiple functions: it provides a walking surface, acts as a positioning mechanism, functions as a sensor platform, and serves as an actuator for movement. This multi-functionality reduces the need for separate systems and simplifies overall control despite the modular complexity.
Solution Approach 2:
The system incorporates autonomous control capabilities where the modular floor can automatically adjust tile positions and movements based on sensor data and pre-programmed sequences, reducing the need for manual control and simplifying operation despite the complex underlying mechanics.

AI summary
A video production system may include a video production environment and a modular floor including a plurality of tiles configured to move independently to induce or respond to a motion for a user or users in contact with the modular floor. The video production environment may include a camera, a stage, and a screen. The screen may provide a digital background. The system may include a processor configured to modify a configuration of the video production environment (e.g., the digital environment or the physical environment) based on a detected characteristic of the user(s) on the modular floor (e.g., an orientation, position, or movement of the user(s)). The system may include a sensor configured to detect the characteristic of the user(s) on the modular floor. Additional systems and associated methods are also disclosed.
