Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If motion sensing controllers are used to capture player input, then player interaction and entertainment value are improved, but measurement precision deteriorates due to electromagnetic interference or distortion
Solution Approach 1:
The system divides the electromagnetic field measurement into multiple independent components by using multiple emitters and receivers positioned at different locations. Each emitter-receiver pair provides independent calibration and gameplay data, allowing the system to segment the measurement process and identify interference patterns that would otherwise compromise overall tracking accuracy.
Solution Approach 2:
The system implements feedback by continuously comparing calibration data (obtained when controllers are stationary) with gameplay data (obtained during active play). This feedback loop enables the system to detect movements of stationary components and electromagnetic distortion in real-time, allowing for dynamic correction of tracking errors and maintenance of measurement precision.
2Measurement precision
If multiple wireless emitters and receivers are integrated to improve tracking accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The multiple wireless emitters and receivers serve multiple functions: they provide calibration data for determining controller position and rotation during gameplay, detect movements of stationary components, and identify electromagnetic distortion. This multi-functionality justifies the added complexity by delivering multiple measurement capabilities through a unified system architecture.
Solution Approach 2:
The system performs preliminary calibration actions by obtaining calibration data before gameplay begins, establishing a baseline for what the electromagnetic field should look like under normal conditions. This preliminary action enables subsequent gameplay data to be interpreted more accurately by comparing against the calibrated state, reducing the complexity of real-time processing.
3Reliability
If calibration and gameplay data are compared to detect movement and distortion, then reliability is improved, but loss of time increases due to additional processing
Solution Approach 1:
The calibration and comparison process operates continuously during gameplay rather than as a separate batch operation. The system continuously compares calibration and gameplay data streams to detect movements and distortion in real-time, ensuring that reliability is maintained without significant time loss, as the useful action of detection and correction occurs concurrently with game play.
