Variable Height Terrain Surface for VR Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality systems fail to simulate varying terrain surfaces, leading to a disconnect between the user's visual and physical experiences, limiting immersion in virtual environments.
Innovation Solution
A variable height terrain surface system with individually adjustable height units and friction elements, controlled by a controller that maps terrain data to simulate the physical experience of a virtual world, allowing for dynamic height adjustments and friction changes to match the virtual terrain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flat surface is provided in conventional VR systems, then the device complexity is reduced, but the user immersion and physical experience are degraded
Solution Approach 1:
The terrain surface is divided into multiple independently controllable height adjusting units arranged in a grid pattern. Each unit can be individually adjusted to create varying terrain heights, allowing complex terrain simulation while maintaining modular system architecture that manages complexity through standardization of individual units
Solution Approach 2:
The terrain surface transitions from a static flat surface to a dynamic variable height surface where each height adjusting unit can change its position in real-time based on terrain data. This dynamic adjustment capability enables the system to adapt to different virtual terrains while using a single reconfigurable physical platform
2Reliability
If the terrain surface is made variable with multiple height adjusting units, then the physical experience is improved, but the device complexity increases
Solution Approach 1:
The controller receives terrain data describing the virtual terrain and uses feedback loops to adjust the height of each unit accordingly. This closed-loop control system ensures that the physical terrain surface accurately reflects the visual representation, improving synchronization while the automated feedback mechanism manages the complexity of controlling multiple units
Solution Approach 2:
The controller serves multiple functions: it receives terrain data, processes the terrain description, maps terrain features to corresponding physical units, and sends adjustment commands to height adjusting units. This multi-functionality consolidates complex control logic into a single universal control system rather than requiring separate control mechanisms for each unit
3Adaptability or versatility
If friction elements are added to simulate terrain materials, then the physical immersion is enhanced, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The friction element is integrated with the height adjusting unit, combining height adjustment and friction control functions into a single modular component. This merging reduces the total number of separate parts, simplifies assembly, and maintains the ability to simulate different terrain materials through variable friction while keeping manufacturing manageable

AI summary
A variable height terrain surface is leveraged in connection with provision of a virtual reality (VR) environment. In one or more implementations, a variable height terrain surface includes a plurality of height adjusting units that are individually adjustable to simulate a terrain described by terrain data. A controller, that is communicably coupled to the variable height terrain surface, maps the terrain described by the terrain data to the height adjusting units. Additionally, the controller causes the height adjusting units to adjust (e.g., vertically) based on the mapping.
