Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors (RGB camera, infrared emitter, infrared detector, depth camera) are integrated to improve object and gesture detection accuracy, then measurement precision and detection capability are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (RGB camera, infrared emitter, infrared detector, and depth camera) into a single integrated processing and projection device. This merging of sensors allows the system to detect both active and passive objects and user gestures with high accuracy by fusing data from different sensor types, while managing the complexity through unified processing architecture.
Solution Approach 2:
The integrated sensor system serves multiple functions: detecting passive objects, detecting active objects, recognizing user gestures, and providing spatial awareness. This multi-functionality allows a single sensor integration to address various detection needs, improving measurement precision across different interaction scenarios without requiring separate specialized systems for each function.
2Adaptability or versatility
If trigger zones are defined in the detection area to provide object-specific feedback, then adaptability and user experience are improved, but device complexity increases
Solution Approach 1:
The detection area is divided into multiple trigger zones with specific functions and characteristics. Each trigger zone can be configured to respond to different object types, gestures, or interaction patterns. This segmentation allows the system to provide targeted, object-specific feedback by determining which trigger zone an object enters or interacts with, enhancing adaptability while managing complexity through modular zone definitions.
Solution Approach 2:
Trigger zones are pre-configured with specific response behaviors and feedback mechanisms before runtime. The system establishes the detection area and defines trigger zones in advance, associating each zone with predetermined feedback actions. This preliminary configuration reduces real-time processing complexity while maintaining high adaptability, as the system only needs to determine which pre-defined zone is activated rather than making complex decisions in real-time.

AI summary
An integrated processing and projection device suitable for use on a supporting surface includes a processor and a projector designed to provide a display on the supporting surface proximate to the device. Various sensors enable object and gesture detection in a detection area in the display area. Trigger zones are defined in the detection area such that interaction of an object or human limb in the detection zone provides object and zone specific feedback by the integrated processing and projection device. The feedback can be provided in the projection area or may be provided as audible or active feedback to a device having active feedback capabilities.
