Personalized Escape Guidance Using Vital-State Route Instructions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In situations where an alarm occurs in a spatial area, individuals unfamiliar with the area or in a panic state may struggle to navigate safely to a designated safe target position due to lack of knowledge or clarity.
Innovation Solution
An escape assistance arrangement comprising a wearable device with vital parameter and geoposition sensors, a navigation unit, and an output unit that calculates and outputs a personalized escape route to a safe target position based on the user's current state, eliminating the need for remote guidance and adapting the route description to the user's condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standardized escape route instruction is provided to all users, then the system complexity is reduced, but the reliability of escape guidance decreases for users in panic state or unfamiliar with the area
Solution Approach 1:
The system performs preliminary classification of the user's state (familiar/unfamiliar with area, panic state or not) before generating escape route instructions. This allows the system to prepare appropriate instruction types in advance and select the most suitable one based on the user's current condition, thereby improving reliability without requiring real-time complex adjustments
Solution Approach 2:
The escape route instruction system is made dynamic by adapting the instruction type (detailed step-by-step, landmark-based, or simple direction) according to the user's classified state. The system can switch between different instruction modes to match the user's cognitive and emotional condition, enhancing reliability while maintaining manageable complexity through predefined instruction templates
2Ease of operation
If detailed step-by-step instructions are provided to all users, then the ease of operation improves for unfamiliar users, but the loss of time increases due to information overload for users in panic state
Solution Approach 1:
The system applies different levels of instruction detail to different user groups based on their classified state. Users unfamiliar with the area receive detailed step-by-step instructions with local quality enhancements (specific landmarks, turn-by-turn directions), while users in panic state receive simplified instructions appropriate to their condition, optimizing both ease of operation and time efficiency for each user segment
Solution Approach 2:
The system changes the parameter of instruction detail level based on the user's state classification. By adjusting this parameter (from detailed to simplified instructions), the system optimizes the balance between ease of understanding and processing time, ensuring that users receive appropriate information density without overload or insufficient guidance

AI summary
The escape assistance arrangement and the escape assistance method guide a user to a safe target position if an alarm situation has occurred in a spatial area and an alarm message has therefore been sent. The user carries an escape assistance device with a vital parameter sensor, a geoposition sensor and an output unit. A navigation unit calculates an escape route for the user, wherein the escape route leads from the current geoposition of the user to the safe target position. The navigation unit generates an escape route description for this escape route. For this purpose, it classifies the user's current state depending on a vital parameter and generates the escape route description depending on the classified current state. The output unit outputs the escape route description.
