Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing augmented reality systems process data from multiple sensors to create accurate 3D avatars and position tracking, then the accuracy and smoothness of the augmented reality experience is improved, but the electrical power consumption and processing requirements increase significantly
Solution Approach 1:
The system divides data processing into multiple stages: initial data collection from sensors, preliminary processing to determine avatar composition, and final rendering. This segmentation allows the system to process only essential data at each stage, reducing overall power consumption while maintaining position tracking accuracy through incremental refinement of avatar position and orientation data.
Solution Approach 2:
The system performs preliminary processing of sensor data to determine avatar composition and basic position information before final rendering. By pre-calculating avatar position, orientation, and composition data from IMU and other sensor inputs, the system reduces the computational burden during real-time rendering, thereby lowering peak power consumption while maintaining tracking precision.
2Reliability
If existing augmented reality systems synthesize multiple streams of data and use algorithms to interpret fields and extract useful information, then the accuracy and effectiveness of the augmented reality experience is improved, but the processing power requirements and device complexity increase
Solution Approach 1:
The system employs a unified coordinate system that serves multiple functions: it defines avatar composition, determines avatar position, tracks user movement, and coordinates multiple sensor inputs. This universal coordinate framework eliminates the need for separate processing systems for each function, reducing overall device complexity while maintaining reliable augmented reality rendering through integrated data synthesis.
Solution Approach 2:
The system combines multiple data streams from IMU, position tracking, and other sensors into a unified avatar position and orientation determination process. By merging these data streams and processing them through a single coordinated system using a common coordinate framework, the system reduces the number of separate processing algorithms needed while maintaining the reliability and accuracy of the augmented reality experience.
