Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If motion capturing using multiple cameras is used to detect user movements accurately, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the motion detection function from complex multi-camera systems and implements it using simpler wearable motion sensors (accelerometers, gyroscopes, magnetometers) that can be worn on the body. This extraction maintains measurement precision for tracking body movements while significantly reducing device complexity by replacing bulky camera equipment with compact sensor modules.
Solution Approach 2:
The patent creates a virtual three-dimensional movement model that copies and represents the user's actual body movements in a digital environment. This virtual model allows accurate visualization and analysis of movements without requiring complex physical measurement equipment, thereby reducing device complexity while maintaining detection accuracy through mathematical modeling and sensor data processing.
2Adaptability or versatility
If a three-dimensional movement model is generated and displayed in any direction, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent transforms two-dimensional sensor data from wearable devices into a three-dimensional virtual movement model that can be viewed from any direction. This dimensional transformation enables versatile viewing flexibility and adaptability for different analysis perspectives while managing processing complexity through efficient rendering techniques and selective detail representation in the virtual environment.
3Ease of operation
If augmented reality display is used to show reproduced moving image with surrounding scene, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges the virtual three-dimensional movement model with the real surrounding scene through augmented reality display technology. This combination allows users to interact with their movement data in an intuitive manner while maintaining awareness of their environment, improving ease of operation by presenting information in a natural, context-aware format without requiring complex separate display systems.

AI summary
A wearable display device includes a controller and a display. The controller acquires, based on output values acquired from a plurality of motion sensors, a three-dimensional movement model of body movements of a person. The person wears the plurality of motion sensors. The controller generates a reproduced moving image that shows the three-dimensional movement model viewed in any direction. The display allows the wearer to visually perceive the reproduced moving image along with a surrounding scene.
