Server-Mediated Location Information Sharing for Digital Signage Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital signage systems face challenges in efficiently providing information to users, including high load on terminals, complex operation requirements, and limited accessibility due to large equipment size and high establishment costs, which leads to reduced chances of information sharing and increased security risks.
Innovation Solution
A system where a server stores information such as advertisements and guides user terminals to connect with nearby information service terminals using GPS, Bluetooth, or Wi-Fi, allowing for simple identification and data transmission without direct loading on the terminals, enabling efficient and cost-effective information sharing across various locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If provision information is directly transmitted from information service terminal to user's terminal, then information sharing is enabled, but load on information service terminal increases significantly
Solution Approach 1:
The patent introduces a server as an intermediary component that mediates between the information service terminal and the user's terminal. The server receives identification information from the user's terminal, retrieves provision information from the terminal via backend communication, and transmits it to the user. This intermediary architecture prevents direct high-load transmission from the terminal to multiple users, resolving the contradiction between enabling information sharing and reducing terminal load.
2Loss of information
If conventional QR code reading and connection operations are required, then information can be obtained, but operation time and complexity increase
Solution Approach 1:
The patent implements self-service functionality where the user's terminal automatically performs identification and connection operations without requiring manual QR code scanning or NFC holding. The terminal autonomously acquires identification information, establishes connection with the server, and retrieves provision information through automated processes, significantly reducing operation time and complexity while enabling information acquisition.
3Loss of information
If user must approach digital signage for visual recognition, then information can be accessed, but accessibility is limited by distance and location
Solution Approach 1:
The patent replaces the mechanical requirement of physical approach and visual recognition with wireless identification technology. The user's terminal automatically detects and acquires identification information from the information service terminal through wireless communication fields, eliminating the need for physical proximity or line-of-sight requirements. This substitution dramatically improves accessibility while enabling information retrieval from any location within communication range.
4Ease of operation
If wireless communication is used for connection, then convenience is improved, but security risks increase due to open network
Solution Approach 1:
The patent implements a feedback-based security mechanism where the server verifies identification information received from the user's terminal before transmitting provision information. The server checks whether the acquired identification information corresponds to a valid information service terminal and authorized user, providing feedback control that prevents unauthorized access. This feedback verification maintains security while preserving the convenience of wireless communication operations.

AI summary
Information service system 10 comprises a server 12 in which provision information such as advertisement, guidance, explanation, news, disaster information and other information is stored, a plurality of information service terminals 14 established at predetermined locations and connected to the server to have the location specified by the server 12 and to receive and provide the provision information according to the corresponding location and a user's terminal 16 positioned at predetermined location to display the same provision information as that provided by the information service terminal 14 established at the corresponding location among the plurality of information service terminals 14. The server specifies the information service terminal established at the location according to the current location of the user's terminal and transmits to the user's terminal the provision information to be provided by the specified information service terminal 14. Thus, by reducing the load of the information service terminals such as a digital signage, the light provision of the information can be achieved and the information service terminals can be simply established at low cost. Therefore, a chance of the provision of the information such as advertisement, etc. can be secured and the user's terminal can share the information such as the advertisement with a simple operation.
