Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If physical motion capture systems are used to generate motion sensor data for computer animated characters, then measurement precision and reliability are improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent creates virtual motion sensor data by copying the functionality of physical motion sensors into the virtual environment. Instead of using actual sensors on animated characters, the system generates synthetic sensor data that mimics what physical sensors would measure, including accelerometer, gyroscope, and magnetometer readings based on character position, orientation, and movement in the virtual scene.
Solution Approach 2:
The patent replaces the mechanical/physical motion capture system with a computational approach. Rather than using physical sensors, cameras, or motion capture equipment, the system uses software algorithms to calculate and generate motion sensor data from virtual character properties, substituting physical measurement mechanisms with mathematical computations.
2Measurement precision
If physical motion capture systems are deployed, then measurement precision is improved, but ease of operation and accessibility worsen
Solution Approach 1:
The virtual environment and animated characters generate their own motion sensor data internally without requiring external measurement systems. The system computes sensor data from the character's own position, orientation, and movement properties within the virtual environment, making the process self-contained and eliminating the need for complex external motion capture equipment.
3Productivity
If virtual motion sensor data generation is implemented, then productivity and ease of operation improve, but measurement precision may worsen compared to physical systems
Solution Approach 1:
The patent changes the parameters and properties of the virtual environment and characters to ensure accurate computation of motion sensor data. By carefully controlling virtual character properties such as position, orientation, movement velocity, and environmental reference frames, the system maintains measurement precision while achieving high productivity through automated data generation.
