Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a calibration process is performed to calculate distances between joints for accurate motion capture, then measurement precision is improved, but the user experience deteriorates due to confusing instructions and awkward poses
Solution Approach 1:
A virtual character is introduced as an intermediary to mediate between the calibration system and the user. The virtual character visually demonstrates the required calibration poses through its body orientation and posture, serving as a intuitive guide that replaces confusing text or audio instructions. This mediator makes the calibration process more user-friendly while maintaining measurement accuracy.
2Measurement precision
If the calibration process is performed before motion capture to ensure accurate joint distances, then measurement precision is improved, but time loss increases due to the separate calibration step
Solution Approach 1:
The calibration process and motion capture process are merged into a unified workflow. The virtual character continuously provides pose guidance throughout the entire process, eliminating the need for a separate, time-consuming calibration phase. Users can perform calibration naturally during normal movement capture, reducing time loss while maintaining precision.
3Measurement precision
If the virtual character abruptly changes from reference pose to calibration pose when calibration ends, then measurement precision is achieved, but the visual continuity deteriorates creating an awkward gesture
Solution Approach 1:
The virtual character's pose transitions are made dynamic and continuous rather than abrupt. During calibration, the character maintains a neutral or natural pose. When calibration completes, the character smoothly transitions to motion capture mode through gradual pose changes, maintaining visual continuity and avoiding awkward gestures while ensuring calibration accuracy was achieved.
