Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current guiding systems in exhibitions, such as QR Code and Radio Frequency systems, interrupt visitors and provide incomplete or inaccurate information due to the need for manual scanning and positional inaccuracies, respectively.
Innovation Solution
A head-mounted device equipped with an image capturing unit, process module, and information interface that captures and recognizes invisible codes in the optical spectrum, calculating relative distance and angle to trigger exhibit-object information presentation only when within a threshold distance, allowing for interactive and accurate information delivery without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If QR Code guiding system is used, then visitors can obtain object information, but visitors must manually hold mobile devices in front of patterns which significantly interrupts visitors
Solution Approach 1:
The system automatically captures images, recognizes invisible codes, calculates distances and angles, and presents information without requiring visitor intervention. The head-mounted device performs all operations autonomously, allowing visitors to simply observe exhibits while the system handles information retrieval and delivery.
Solution Approach 2:
The patent replaces the manual mechanical action of holding and positioning a mobile device with an automated optical recognition system. The image capturing unit automatically acquires images, and the recognition unit identifies invisible codes without physical contact or manual positioning by the visitor.
2Device complexity
If one object displays one kind of object information at a time, then information presentation is simple, but visitors cannot obtain comprehensive understanding of exhibition objects
Solution Approach 1:
The system dynamically adjusts information presentation based on real-time calculated distance and angle parameters. As visitors move closer or change viewing angles, the system automatically updates which information to display, enabling comprehensive multi-dimensional information delivery that adapts to visitor position and behavior.
Solution Approach 2:
The patent uses changes in distance and angle parameters to trigger different information presentations. By monitoring these parameters, the system determines when to activate the information interface and what type of information to display, enabling comprehensive object information delivery based on visitor proximity and orientation.
3Loss of information
If Radio Frequency guiding system is used, then visitors can receive object information, but positional accuracy is insufficient causing interruptions in exhibition
Solution Approach 1:
The patent replaces Radio Frequency positioning with an optical-based vision system. The image capturing unit captures images of invisible codes, and the computing unit calculates precise distance and angle measurements based on code size and position in the image, achieving superior positioning accuracy compared to RF methods.
Solution Approach 2:
The invisible code serves as an intermediary object that enables precise measurement. By capturing the invisible code in an image and analyzing its size and position, the system indirectly determines the distance and angle to the exhibit object with high precision, avoiding direct positioning challenges.

Data Source
AI summary
A head mounted device suitable for guiding an exhibition is disclosed. The head mounted device includes an image capturing unit, a process module and an information interface. The process module includes a recognition unit, a computing unit and a control unit. The image capturing unit captures an input image in invisible spectrum. The recognition unit recognizes an invisible code from the input image. The computing unit calculates a relative distance and a relative angle between the head mounted device and an exhibition object. By comparing the relative distance with a threshold distance, the control unit determines whether to trigger the information interface and present an exhibit-object introduction based on relative distance and relative angle.
