Hearing Device Alert System for Vehicle Danger Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing devices struggle to provide effective alerts for potentially dangerous vehicles in the vicinity of users while avoiding unnecessary alerts that can distract or annoy users, especially in complex traffic situations, as existing systems lack precise methods to determine the user's awareness and the actual danger level.
Innovation Solution
A method and system that utilize user-related and vehicle-related data to determine a relevance measure indicating the probability of user endangerment, allowing for controlled alerts that are tailored to the user's awareness and the specific traffic situation, including modifying audio signals and venting channel settings to focus attention on potential dangers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hearing device provides alerts for all detected vehicles, then the user is reliably informed about potential dangers, but the user is overloaded with unnecessary alerts that cause distraction and annoyance
Solution Approach 1:
The system dynamically adjusts alert generation based on multiple parameters including user awareness state, vehicle danger level, and traffic situation context. By changing the parameters that control alert generation (from static to dynamic), the system achieves both reliable safety alerts and reduced unnecessary distractions
Solution Approach 2:
The system incorporates feedback loops that continuously monitor user awareness state and adjust alert behavior accordingly. The hearing device receives feedback about user state and vehicle conditions, then adapts its alert generation in real-time to balance safety and user comfort
2Reliability
If the hearing device provides frequent alerts to ensure safety, then the user is reliably warned about dangers, but the alert effectiveness decreases due to user annoyance and distraction
Solution Approach 1:
The system changes the parameter of alert frequency from fixed to variable, adjusting it based on assessed danger levels and user awareness. This allows the system to maintain high alert effectiveness for dangerous situations while reducing alerts to minimal necessary levels for safe situations
Solution Approach 2:
The system applies partial action by providing alerts only for the specific subset of vehicles that pose actual danger, rather than alerting for all detected vehicles. This selective approach maintains safety while preserving alert effectiveness
3Measurement precision
If the hearing device monitors multiple traffic parameters to accurately assess danger, then the alert precision is improved, but the device complexity increases
Solution Approach 1:
The hearing device leverages its existing multi-functional capabilities (audio processing, environmental sensing, user interaction) to perform danger assessment without requiring entirely new specialized subsystems. This universal approach achieves precise monitoring while managing device complexity
Data Source
AI summary
A method of providing an alert for a user by a hearing device configured to be worn at an ear of the user includes providing user-related data including information about at least one of the user, an ambient environment of the user, or a property of the hearing device worn by the user; characterized by providing vehicle-related data associated with at least one vehicle in a vicinity of the user, the vehicle-related data including information about a property of the vehicle; determining, based on the user-related data and the vehicle-related data, a relevance measure indicative of a probability that the user is endangered by the vehicle; and controlling an operation of the hearing device depending on the relevance measure, the operation alerting the user about the vehicle.
