Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual digital information is superimposed on real space information using position and posture information only, then the virtual object can be positioned in 3D space, but the virtual object cannot exhibit realistic movements consistent with real-world physics
Solution Approach 1:
The system performs preliminary detection of gravity direction using acceleration sensors before rendering virtual objects. By detecting the gravity direction in advance and reflecting it in the virtual space coordinate system, the system ensures that virtual objects will exhibit realistic gravitational behavior (such as falling downward) from the moment they are displayed, rather than requiring post-processing or user input.
2Reliability
If the system detects and reflects gravity direction in real-time, then virtual objects can move realistically, but the system requires additional sensors and processing complexity
Solution Approach 1:
The acceleration sensor serves multiple functions: it detects both the device's motion/acceleration for general AR tracking purposes and simultaneously detects the gravity direction for realistic virtual object behavior. By making the detection system multi-functional, the patent avoids adding dedicated gravity sensors while still achieving accurate gravity reflection in the virtual space.
3Ease of operation
If the virtual space coordinate system is fixed relative to the device, then rendering is simple, but the virtual object does not respond to changes in device orientation relative to gravity
Solution Approach 1:
The virtual space coordinate system is made dynamic by continuously updating its orientation based on detected gravity direction. Instead of being fixed to the device, the coordinate system adapts its orientation to reflect the actual gravity direction detected by sensors, allowing virtual objects to consistently respond to gravity regardless of device orientation while maintaining rendering efficiency through systematic coordinate transformation.
