Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality interfaces and human-machine interfaces lack flexibility and calibration, failing to effectively guide and assist operators in dynamic work environments, and there is a need for systems that can easily integrate and calibrate projector and sensor devices for real-time interaction and feedback.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If projection devices and sensor devices are manually calibrated before use, then calibration accuracy can be achieved, but setup time and operational complexity increase significantly
Solution Approach 1:
The system performs calibration actions automatically during the setup phase without requiring manual intervention. The projector and sensor devices self-calibrate using predefined algorithms and patterns, eliminating the need for operators to perform time-consuming manual calibration procedures while ensuring accurate alignment between the projection and sensing systems
Solution Approach 2:
The calibration system is self-sufficient and does not require external manual calibration tools or expert intervention. The projector-sensor apparatus automatically detects its own parameters, computes calibration transformations, and adjusts its operation to achieve precise alignment, making the system self-calibrating and reducing dependency on manual processes
2Ease of manufacture
If commercial off-the-shelf projection and sensor systems are used, then system availability and cost-effectiveness improve, but integrated calibration capability and ready-to-use functionality deteriorate
Solution Approach 1:
The patent combines separate projector and sensor devices into an integrated apparatus where both components work together as a unified system. This merging enables automatic calibration between the projection and sensing subsystems, allowing COTS components to function together seamlessly with built-in coordination and calibration capabilities that neither component would have independently
Solution Approach 2:
The integrated projector-sensor apparatus serves multiple functions: it projects augmented reality content, detects user interactions through the sensor, performs self-calibration, and provides real-time feedback. This multi-functionality allows a single system to replace multiple separate devices while maintaining adaptability to different application scenarios through its coordinated operation
3Productivity
If existing human-machine interfaces are designed for machine automation and control, then machine control efficiency improves, but flexibility and ability to guide human operators deteriorate
Solution Approach 1:
The interface system dynamically adapts its behavior based on the operator's actions and the workspace context. Rather than presenting fixed controls, the system projects contextual information and guidance directly into the workspace, allowing the interface to evolve and respond to operator needs in real-time, thereby enhancing both flexibility and operator support while maintaining control efficiency
