Wearable Device Emergency Detection via Multi-User Sensor Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, individuals often fail to notify emergency service providers due to being preoccupied with immediate survival, and existing technologies require manual activation of mobile or wearable devices to alert services, which can be inefficient.
Innovation Solution
A system that automatically or prompts users to confirm the need for an emergency call based on synchronized sensor data from multiple users' heart rate or motion sensors, establishing a communication connection with emergency services if a dangerous situation is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual activation of mobile or wearable devices is required to notify emergency services, then device complexity remains low, but response time increases and productivity decreases
Solution Approach 1:
The system performs preliminary actions by continuously monitoring sensor data (heart rate, motion) and pre-processing it to detect emergency patterns before manual activation is needed. The system is already in a state to recognize emergencies, eliminating the delay between emergency occurrence and system activation.
Solution Approach 2:
The system enables self-service by automatically detecting emergencies through sensor data analysis and initiating emergency notifications without requiring manual user activation. The wearable device autonomously monitors its own state and the states of nearby devices, automatically determining when emergency services should be contacted.
2Productivity
If automatic emergency detection is implemented using sensor data from multiple users, then response time improves, but device complexity and processing requirements increase
Solution Approach 1:
The system segments the emergency detection task by dividing sensor data processing into individual device-level preliminary analysis and centralized coordination. Each device independently monitors its own sensor data and shares relevant information, distributing the computational burden rather than requiring one device to process all data centrally.
Solution Approach 2:
The system merges data from multiple wearable devices to improve detection reliability. By combining sensor data from multiple users in proximity, the system achieves more accurate emergency detection while distributing processing requirements across the network of devices rather than concentrating all processing in one location.
3Reliability
If multiple users confirm emergency need, then false alarms are reduced, but time to establish emergency connection increases
Solution Approach 1:
The system performs preliminary analysis of sensor data to identify patterns indicative of genuine emergencies before requesting user confirmation. By pre-evaluating the credibility of the emergency signal based on sensor patterns, the system can reduce the number of confirmations needed or prioritize cases that clearly indicate real emergencies.
Solution Approach 2:
The system uses feedback from sensor data patterns to dynamically adjust confirmation requirements. When sensor patterns strongly indicate a genuine emergency (e.g., consistent heart rate spikes across multiple devices), the system reduces confirmation requirements. When patterns are ambiguous, it maintains higher confirmation thresholds, optimizing both speed and accuracy.

AI summary
Systems and methods for triggering an emergency call based on sensor data indicative of the response of a number of users in a given location to a possible emergency situation are provided. In an example computer-implemented method, an indication of data captured by respective sensors associated with each of a plurality of individuals in a geographic area may be received, and an indication that each of the plurality of individuals is reacting to a possible dangerous situation in the geographic area may be determined based on the data captured by the respective sensors associated with each of the plurality of individuals. A communication connection may be established with an emergency services dispatcher to facilitate dispatching emergency services to the geographic area based on the indication that each of the plurality of individuals is reacting to the possible dangerous situation in the geographic area.
