Transit Voice Output with Guide-First Advertising Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice output methods in public transportation, such as in fixed-route buses, do not consider the needs of visually impaired passengers, potentially distracting them with advertising voices that hinder their ability to grasp their surroundings.
Innovation Solution
A voice output method that stores separate guide and advertising voices, determines if a visually impaired person is present, and restrains advertising voice output when necessary, while maintaining guide voice availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If advertising voice is output in the vehicle, then advertising effectiveness is improved, but visually impaired person's grasp of situation is distracted
Solution Approach 1:
The system dynamically adjusts the advertising voice output based on real-time detection of visually impaired persons. When a visually impaired person is detected, the advertising voice output is restrained or stopped. When no visually impaired person is present, normal advertising voice output resumes. This dynamic adaptation resolves the contradiction by making advertising effectiveness conditional on passenger composition.
Solution Approach 2:
The system changes the output parameter (advertising voice) based on the detected presence of visually impaired persons. The output state transitions between 'normal output' and 'restrained output' depending on the parameter 'visually impaired person detection result'. This parameter-based control resolves the contradiction by adapting advertising delivery to passenger needs.
2Duration of action of moving object
If advertising voice is output continuously, then advertising coverage is improved, but guide voice clarity for visually impaired person is reduced
Solution Approach 1:
The system implements periodic detection of visually impaired persons and adjusts advertising voice output accordingly. The advertising voice is output during periods when no visually impaired person is detected, and restrained during periods when one is detected. This periodic monitoring and adaptive control ensures guide voice clarity is maintained when needed while preserving advertising coverage during appropriate periods.
3Power
If advertising voice volume is increased, then advertising impact is improved, but surrounding situation awareness for visually impaired person is hindered
Solution Approach 1:
The system extracts or removes the advertising voice output when a visually impaired person is detected, separating the advertising function from the passenger information environment. This extraction eliminates the harmful effect of advertising voice on surrounding situation awareness while preserving the advertising capability for periods when it is appropriate.

AI summary
A voice output method is a voice output method in a moving body of public transportation. The voice output method includes: a storage step of storing a voice output to an inside of the moving body, the voice being stored by being divided into a guide voice related to information on the moving body and an advertising voice related to advertising; a determination step of determining whether or not a passenger of the moving body includes a visually impaired person; and a restraint step of, by the moving body, restraining the advertising voice from being output when determination is made that the passenger includes the visually impaired person.
