Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If accelerometer and gyros are used for position tracking in AR, then the system can provide virtual display functionality, but drift occurs compromising positioning accuracy
Solution Approach 1:
The patent introduces visual markers as an intermediary reference system between the AR headset and the physical environment. These markers provide a stable, drift-free reference frame that mediates the positioning relationship, allowing the virtual display to be accurately anchored to physical locations without relying on drift-prone accelerometer and gyro integration over time.
2Measurement precision
If wide angle cameras are used on the headset for visual tracking, then positioning accuracy improves, but the appearance of the headset is affected and expense increases
Solution Approach 1:
The patent makes the environment serve the tracking function rather than modifying the headset. By placing visual markers in the physical environment, the system uses the environment itself as the tracking reference, eliminating the need for additional cameras or sensors on the headset while maintaining high positioning accuracy.
3Measurement precision
If multiple stationary tracking cameras and infrared light emitting diodes are used, then positioning accuracy improves, but undesired equipment and cost are added
Solution Approach 1:
The patent uses visual markers that can be captured by the headset's existing camera, creating a digital copy of the physical marker positions. This approach replicates the functionality of complex infrared tracking systems using only visible light and standard camera capabilities, eliminating the need for specialized infrared equipment.
4Area of stationary object
If virtual display overlays physical display, then screen real estate is expanded, but materials on physical display interfere with virtual display readability
Solution Approach 1:
The patent transitions the virtual display from a two-dimensional overlay on the physical screen to a three-dimensional projection in physical space. By projecting the virtual display onto surfaces in the real world rather than overlaying it on the physical display, the system expands screen real estate while eliminating interference between physical and virtual content.
5Stability of the object's composition
If virtual content remains in the same world location after placement, then tracking stability is maintained, but the display cannot be re-centered to desired orientation
Solution Approach 1:
The patent implements a dynamic virtual display system where the display can be re-centered by detecting the user's head orientation and adjusting the virtual display position accordingly. The system maintains stability through continuous tracking of the reference marker while allowing dynamic repositioning of the virtual display to match the user's desired viewing orientation.
