Telecommunication Method for Visually Impaired Transport Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for visually impaired individuals in public transport settings lack reliable and remote access to complex services, such as route guidance and real-time transport information, and are hindered by limitations in communication networks like infrared, which become ineffective with obstacles, and suffer from identifier degradation issues in remote control methods.
Innovation Solution
A telecommunications method that establishes communication between a mobile terminal and a central unit via a communication network, where a unique identifier is verified, and after authorization, service requests are sent, allowing control commands to be executed by equipment, using geolocation and short-range wireless communication to ensure secure and efficient access to remote-controlled services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If infrared communication is used for remote control, then simple communication can be established, but the system becomes inoperative when obstacles block the transmitter and receiver
Solution Approach 1:
The patent introduces a centralized computer system as an intermediary between the mobile terminal and the equipment to be controlled. This mediator receives control requests from the mobile terminal, processes them centrally, and executes commands on the target equipment, thereby eliminating the need for direct line-of-sight communication and overcoming obstacle blockage issues while maintaining system simplicity
2Ease of operation
If identifier transmission is used for remote control authorization, then access control can be implemented, but identifier degradation causes random or incomplete reading that prevents remote activation
Solution Approach 1:
The patent implements a feedback mechanism where the centralized computer system receives the transmitted identifier, verifies its completeness and accuracy through validation processes, and requests retransmission if the identifier is degraded or incomplete. This feedback loop ensures reliable authorization without requiring perfect initial transmission
Solution Approach 2:
The system performs preliminary verification of the transmitted identifier before processing the control request. By checking the identifier's integrity in advance and rejecting incomplete transmissions, the system prevents authorization failures and ensures only valid control requests are processed
3Loss of information
If general communication networks are used for service access, then comprehensive information can be transmitted, but visually impaired individuals cannot access reserved services with adapted control
Solution Approach 1:
The patent implements local quality by providing customized, adapted interfaces and control methods specifically designed for visually impaired users through mobile terminals. The system delivers comprehensive transport information while incorporating accessibility features such as audio output and simplified interaction protocols, allowing these users to access reserved services with adapted control mechanisms
Data Source
AI summary
The method involves transmitting a response (5) to a central unit (2) i.e. road network, parking and traffic managing server, after a positive verification of a calling mobile terminal (1) i.e. mobile telephone. Elements responding to the response are determined from data of a service file stored in a storage unit, where each element is a distinct device to be controlled i.e. mobile terminal (4). A control order permitting execution of control by the device to be controlled is transmitted to the calling mobile terminal or to an order receiver (7) of the device to be controlled.
