Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both walk-through mode and locomotion mode are implemented in one experience space, then the versatility of the virtual reality system is improved, but the safety and user separation is compromised
Solution Approach 1:
The system dynamically adjusts the play space configuration based on the active mode. When switching from walk-through mode to locomotion mode, the system automatically repositions users to maintain appropriate distances, and when switching back, it restores the original spatial arrangement. This dynamic adaptation allows the same physical space to safely support both modes sequentially.
Solution Approach 2:
Before transitioning between modes, the system performs preliminary spatial adjustments. When converting from walk-through to locomotion mode, the system proactively increases the distance between users in advance, ensuring safety before the mode change is fully activated. This prevents potential collisions or discomfort during the transition.
2Reliability
If user distance is increased for locomotion mode safety, then user separation safety is improved, but the immersion and social interaction are reduced
Solution Approach 1:
The spatial configuration is dynamically adjusted based on the active mode. During locomotion mode, users are positioned farther apart for safety, while during walk-through mode, the system restores closer positioning to enhance immersion and social interaction. This dynamic switching ensures that immersion quality is optimized for each specific mode rather than being constrained by a fixed distance.
3Ease of operation
If mode conversion is implemented without spatial adjustment, then the ease of operation is improved, but the user safety is compromised
Solution Approach 1:
The system automatically performs spatial adjustments as a preliminary step before mode conversion is finalized. When a user initiates a mode switch, the system proactively repositions users to appropriate distances for the target mode, ensuring safety without requiring manual intervention. This maintains ease of operation while preventing safety issues.
