Helmet Transit Alert System with Dynamic Radius and Directional Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation and mapping systems lack flexibility in adapting to new or changing traffic conditions and do not allow users to spontaneously avoid road alerts in 'free roam' or 'free navigation' modes, failing to provide timely alerts for adjacent route traffic congestion.
Innovation Solution
A method and system that determine a user's current location and transit direction, retrieve relevant transit alerts within a defined area, and alert the user visually or audibly, with the ability to project a transit path and exclude alerts outside this path, prioritizing alerts based on distance and turns from the direction, and dynamically adjust alert radius and priority based on user speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system provides alerts for all transit areas, then the user receives comprehensive alert coverage, but the user experiences information overload and reduced attention to critical alerts
Solution Approach 1:
The system applies local quality by differentiating alert treatment based on spatial proximity and directional relevance. Alerts are selectively filtered and prioritized based on their location relative to the user's current position and transit direction, ensuring that only locally relevant alerts are presented to the user, thereby reducing information overload while maintaining comprehensive coverage where needed.
Solution Approach 2:
The system segments the transit area into multiple zones based on distance from the user and directional alignment with the transit path. This segmentation allows the system to process and present alerts in organized batches, prioritizing those in the immediate forward direction while filtering out less relevant alerts from peripheral areas, thus managing information flow effectively.
2Adaptability or versatility
If the system uses a fixed alert radius, then the system is simple to implement, but it cannot adapt to changing user speed and transit conditions
Solution Approach 1:
The system implements dynamics by making the alert radius variable rather than fixed. The radius automatically adjusts based on detected user speed, transit conditions, and temporal factors. This dynamic adjustment allows the system to adapt to changing user behavior patterns and environmental conditions, improving alert relevance without requiring complex manual configuration.
Solution Approach 2:
The system changes the parameter of alert radius based on detected user speed and transit conditions. When users travel at higher speeds, the radius expands to capture alerts sooner, while at lower speeds it contracts to reduce unnecessary alerts. This parameter change approach enables automatic adaptation to varying conditions without adding significant system complexity.
3Adaptability or versatility
If the system alerts users to all transit alerts regardless of direction, then the user receives complete information, but the user cannot spontaneously avoid alerts in free roam mode
Solution Approach 1:
The system performs preliminary action by pre-calculating the projected transit path based on the user's current direction and speed before presenting alerts. This allows the system to filter alerts based on whether they lie along the projected path, enabling users to spontaneously avoid alerts by changing direction while still receiving relevant information about alerts that would be encountered on the natural transit path.
Solution Approach 2:
The system incorporates feedback by continuously monitoring user position, speed, and direction changes, and dynamically adjusting the projected transit path and alert filtering criteria accordingly. This feedback mechanism ensures that the system adapts to user behavior in real-time, allowing free roam navigation while maintaining appropriate alert relevance through continuous adjustment rather than static filtering.

AI summary
The present disclosure relates to methods and systems for providing alerts to a helmet user. A method includes determining a current location of the user, determining a transit area and a transit direction of the user based on the current location, retrieving records of transit alerts based on the transit area of the user, selecting relevant transit alerts from the records of transit alerts based on the transit direction of the user, and alerting the user of the relevant transit alerts.
