Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive display systems face challenges in accurately separating the motion of physical objects from projected objects, leading to complex and error-prone detection processes.
Innovation Solution
The system employs IR object detection using IR-reflective or IR-generating objects, which are identified by an IR camera, allowing for precise separation of physical and projected object motion through the use of IR light and image processing techniques, such as IR filters and RGBIR sensors, to project interactive environments responsive to the detected motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a typical camera-based motion detection system is used to identify objects and detect motion in an interactive display environment, then the system can identify objects and track their movement, but it becomes complex and error-prone when attempting to separate the motion of physical objects from projected objects
Solution Approach 1:
The patent segments the detection task by using separate detection systems for different types of objects: an IR camera specifically for detecting physical objects and a visible light camera specifically for detecting projected objects. This segmentation eliminates the complexity of trying to separate motions within a single mixed detection system, as each camera type is optimized for its specific detection target.
Solution Approach 2:
The patent introduces an intermediary computational layer that processes data from both IR and visible light cameras separately before combining the results. This intermediary processing stage allows for clean separation of physical and projected object motions by maintaining distinct detection streams that can be independently analyzed and then integrated in the final interactive display output.
2Device complexity
If a single camera system is used to detect both physical objects and projected objects, then the system structure is simpler, but the detection precision and reliability decrease when separating object motions
Solution Approach 1:
The patent divides the detection system into two specialized segments: an IR camera segment for physical object detection and a visible light camera segment for projected object detection. This segmentation sacrifices some structural simplicity but dramatically improves measurement precision by eliminating cross-interference between physical and projected object detections.
Solution Approach 2:
The patent applies local quality by optimizing each detection system for its specific detection target: the IR camera is optimized with IR sensitivity and filtering for physical objects, while the visible light camera is optimized with visible light sensitivity for projected objects. This localized optimization ensures high detection precision for each object type without compromising the other.

AI summary
Some embodiments herein include systems, methods, and software for IR object identification and motion detection. Consumers may project an interactive projection surface on the wall or floor of any room, and when IR object motion is detected, the interactive projection may update in response to the motion. A newly introduced IR object may be identified, and an effect specific to the IR object may be projected into the IR object.
