Camera Gesture Checkpoints for Real-Time Guardian Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal security systems for travelers fail to promptly notify guardians of potential danger during journeys due to delayed notifications, inappropriate guardian location, lack of real-time monitoring, and ineffective user gestures for indicating danger.
Innovation Solution
A system that allows users to select gesture monitoring points equipped with cameras, choose gestures, and designate guardians, notifying them if expected gestures are not received, thereby ensuring timely and location-specific alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system uses expected time of travel to notify guardians, then the notification is triggered, but the notification is delayed until the expected time passes
Solution Approach 1:
The system performs preliminary actions by establishing expected gesture checkpoints along the route before the traveler arrives. Each checkpoint has a predetermined gesture requirement that must be completed within an expected time window. This preliminary setup enables real-time monitoring and immediate notification when gestures are not received, eliminating the delay inherent in post-event time-based notifications.
Solution Approach 2:
The system implements continuous feedback by monitoring whether the traveler provides expected gestures at each checkpoint within the expected time window. The system compares actual traveler behavior against the predefined gesture expectations and immediately notifies the guardian when deviations occur. This feedback mechanism transforms the notification system from passive time-based triggering to active real-time monitoring.
2Device complexity
If the system notifies a single guardian at a fixed location, then the notification is simple, but the guardian may not be optimally positioned to respond to incidents at different locations
Solution Approach 1:
The system segments the notification function by assigning different guardians to different geographic segments or checkpoints along the route. Each segment can have its own designated guardian who is optimally positioned to respond to incidents at that location. This segmentation maintains relative simplicity while significantly improving response effectiveness by matching guardians to their optimal response zones.
Solution Approach 2:
The system applies local quality by allowing different guardians to be assigned to different locations along the route based on their proximity and optimal response capability. Each location or checkpoint has the quality attribute of being assigned to the most appropriate guardian for that specific area, rather than using a single fixed guardian for the entire route. This localizes the notification system to match guardian capabilities with incident locations.
3Reliability
If the system monitors the entire route continuously, then real-time safety is improved, but the system complexity and resource requirements increase
Solution Approach 1:
The system segments the continuous monitoring function into discrete checkpoint intervals along the route. Instead of monitoring the entire route as a single continuous stream, the system divides it into multiple gesturemonitoring points, each with its own gesture expectations and time windows. This segmentation reduces the complexity of individual monitoring units while maintaining comprehensive coverage through multiple distributed checkpoints.
Solution Approach 2:
The system applies partial action by monitoring for specific expected gestures at designated checkpoints rather than continuously analyzing all traveler movements. The system focuses monitoring resources on the critical gesture completion task at each checkpoint within the expected time window, rather than attempting to monitor every possible traveler action along the entire route. This selective monitoring maintains real-time safety awareness while reducing system complexity.

AI summary
Techniques for notifying a guardian when an expected gesture from a monitored user is not received are provided. A start point and a destination point are received from the monitored user. A route from the start point to the destination point that includes a gesture monitoring point is determined. The gesture monitoring point includes a camera capable of gesture detection. A selection of the gesture monitoring points to be monitored is received. An expected gesture for each of the selected gesture monitoring points is received. A guardian to be informed when the expected gesture is not received. The monitored user is tracked as they traverse the route. The guardian is notified when the expected gesture for the selection of gesture monitoring points is not detected from the monitored user when the monitored user passes through a field of view of the camera associated with the selected gesture monitoring points.
