NFC Guidance System Using Fixed and Insertion Phrases
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guidance systems at transportation sites and exhibition facilities require large amounts of data to provide users with various guidance information, making it inefficient, especially for hard-of-hearing individuals and foreign language speakers.
Innovation Solution
A system that uses near field communication to transmit fixed phrase information and insertion phrase information to a terminal device, allowing the device to generate and present guidance information by inserting selected insertion phrases into fixed phrases, reducing the amount of data needed and enabling efficient communication of guidance voices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If guidance information is individually prepared for each content (e.g., for each stop point), then users can receive comprehensive guidance information, but the amount of data required becomes large
Solution Approach 1:
The guidance information is segmented into a fixed phrase portion and an insertion phrase portion. The fixed phrase contains common guidance structures that remain unchanged, while the insertion phrase contains variable information specific to each stop point or location. This segmentation allows the system to reuse the fixed phrase across multiple guidance instances, significantly reducing the total data storage requirement while maintaining comprehensive guidance coverage.
Solution Approach 2:
The fixed phrase serves as a universal template that can be applied to multiple different guidance scenarios. By designing the fixed phrase to contain通用的 guidance structures and instructions, the system can generate diverse guidance information by simply changing the insertion phrase, making the fixed phrase multi-functional and reducing the need to store separate complete guidance texts for each scenario.
2Speed
If near field communication is used to transmit guidance information, then data transmission speed improves, but the communication range is limited
Solution Approach 1:
The terminal device stores multiple insertion phrases in advance before the actual guidance transmission occurs. When the information provision device transmits the fixed phrase and selects an insertion phrase via near field communication, the terminal device can immediately combine them without needing to request additional data. This preliminary preparation reduces the amount of data that needs to be transmitted through the limited-range near field communication channel, making the system work within the communication range constraint while maintaining high transmission speed.

Function Achieved in This Case
This approach reduces the data required for guidance information, allowing for efficient communication of guidance voices and presentation of information to users, including translations and visual displays, thereby improving accessibility for all users.
Implementation Method 1
transmit, by near field communication, fixed phrase information, of guidance information that guides a user, representative of a fixed phrase and insertion phrase information
Data Source
AI summary
An information provision device transmits, by near field communication, fixed phrase information, of guidance information that guides a user, representative of a fixed phrase and insertion phrase information selected from among a plurality of pieces of insertion phrase information representative of different insertion phrases to be inserted in the fixed phrase, to a terminal device capable of presenting, to the user, presentation information corresponding to the guidance information where the insertion phrase represented by the insertion phrase information is inserted in the fixed phrase represented by the fixed phrase information.
