Pedestrian-Area Sound Control for Mobile Object Noticeability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pedestrians may not be aware of approaching mobile objects due to ambient noise, making it difficult to notice their presence.
Innovation Solution
An information processing apparatus that identifies sound-generating devices in the vicinity of a pedestrian and controls the sound output from these devices to be reduced, allowing pedestrians to better notice approaching mobile objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound-generating devices operate normally in the vicinity of pedestrians, then device functionality is maintained, but pedestrian awareness of approaching mobile objects is reduced due to ambient noise
Solution Approach 1:
The sound output of identified devices is dynamically adjusted based on the presence and proximity of pedestrians and mobile objects. The controller modifies operational parameters of sound-generating devices in real-time, transitioning between different sound output states to optimize pedestrian awareness while maintaining device functionality.
Solution Approach 2:
The system changes the sound output parameter of identified devices by transmitting control signals that adjust volume levels or operational modes. This parameter modification reduces ambient noise interference and enhances the detectability of mobile object approach sounds for pedestrians.
2Reliability
If sound output from identified devices is reduced, then pedestrian awareness of mobile objects is improved, but device operational effectiveness is compromised
Solution Approach 1:
The system dynamically adjusts sound output levels based on real-time spatial relationships between pedestrians, mobile objects, and sound-generating devices. Device effectiveness is maintained by restoring normal sound output when pedestrians are not in proximity or when mobile objects are not approaching, while reducing sound output only when and where needed for pedestrian safety.
Solution Approach 2:
The sound reduction is applied locally and selectively to specific devices in the vicinity of pedestrians rather than globally to all devices. This localized approach ensures that device effectiveness is maintained in areas where pedestrians are not present, while enhancing pedestrian awareness in critical zones where mobile objects are approaching pedestrians.
3Reliability
If the system controls sound from multiple devices, then pedestrian awareness is significantly improved, but system complexity increases
Solution Approach 1:
The system employs an information processing apparatus as an intermediary that coordinates control signals to multiple sound-generating devices. This central intermediary manages the complexity of multi-device coordination by sequentially identifying devices and transmitting control signals, simplifying the overall system architecture while achieving comprehensive sound control for enhanced pedestrian awareness.

AI summary
An information processing apparatus includes a controller. The controller is configured to identify a device that generates sound within a surrounding area of a pedestrian upon detecting a first mobile object traveling in a vicinity of the pedestrian, and control the sound generated from the identified device to be reduced.
