Solution Overview
Problem
Current virtual reality (VR) experiences using omnidirectional treadmills lack immersive simulation of topographical features, failing to effectively translate VR elements into physical sensations for users.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active elements are activated to simulate VR topography, then immersion and realism are improved, but device complexity increases
Solution Approach 1:
The treadmill surface is divided into multiple independent active elements (e.g., modular actuators, segmented belts, or discrete tread segments) that can be individually controlled. This segmentation allows the system to simulate complex topographical features by coordinating specific segments while keeping the overall device architecture manageable and scalable.
Solution Approach 2:
The active elements are designed to dynamically adjust their state (position, height, or motion) in real-time based on VR topographical data. This dynamic capability enables the treadmill to transform from a static surface to an adaptive simulation environment, enhancing immersion without requiring a completely redesign of the entire system.
2Adaptability or versatility
If multiple active elements are used to simulate diverse VR elements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The active elements are designed with universal functionality, where each element can perform multiple simulation tasks (e.g., simulating stairs, obstacles, slopes, or uneven terrain) through coordinated activation patterns. This multi-functionality allows a single modular element design to replace what would otherwise require multiple specialized components, thereby enhancing adaptability while controlling complexity.
Solution Approach 2:
The system achieves diverse topographical simulations by changing parameters such as activation timing, activation intensity, spatial distribution, and motion patterns of the active elements. Rather than requiring physically different components for each terrain type, the same hardware configuration can simulate various environments through parameter adjustment, greatly improving adaptability without increasing device complexity.
3Reliability
If the treadmill surface is made interactive with active elements, then user experience is improved, but ease of operation decreases
Solution Approach 1:
The treadmill system operates autonomously by receiving VR topographical data and automatically activating the appropriate active elements without requiring manual user input. The system self-regulates the simulation based on the virtual environment parameters, eliminating the need for users to manually control or adjust the physical surface, thus maintaining ease of operation while delivering enhanced user experience.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor user position, movement, and interaction with the simulated terrain, then dynamically adjust active element activation in real-time. This closed-loop control ensures the physical simulation remains synchronized with the virtual environment and user actions, creating an intuitive and effortless experience where the system adapts to user needs automatically.

AI summary
Embodiments herein describe techniques for operating an omnidirectional treadmill, the techniques include receiving VR (virtual reality) topographical information comprising a VR environment, and displaying the VR environment to a user wearing a headset. VR topographical information includes information about VR elements in front of the user in the VR environment relative to a facing direction of the user in the VR environment. The method includes sending topographical signals to active elements in an omnidirectional treadmill based upon the VR topographical information where the omnidirectional treadmill permits the user to move along at least two perpendicular directions of motion on a surface of the omnidirectional treadmill. The techniques include activating the active elements, based upon the VR topographical signals, to physically simulate the VR elements in the VR topographical information on the surface by at least one of expanding or contracting the active elements.
