Watcher Identification Using Gaze Detection at Incident Scenes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video recording and playback systems are unable to reliably identify whether objects of interest at an incident scene are being watched by public safety personnel, as multiple objects may be present in a responder's field of view, and video sources may not be associated with individual responders, making it difficult to determine who is observing what during an incident.
Innovation Solution
A system and method that utilize a communication interface and electronic processor to receive an object identifier, determine a watcher status, and generate notifications to ensure that objects of interest are adequately monitored by transmitting notifications to available watchers at the incident scene, using video devices and cameras to capture and process video streams, and employing gaze detection techniques to associate watchers with observed objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video recording devices are used to document incident scenes, then visual control and evidence collection are improved, but the ability to identify specific watchers of specific objects is lost
Solution Approach 1:
The patent introduces an intermediary system comprising gaze detection devices, object detection devices, and a communication system that mediates between the video recording devices and the watchers. This intermediary layer captures and transmits watcher identification information without interfering with the primary video documentation function, thereby resolving the contradiction between maintaining evidence integrity and preserving watcher identification information.
2Area of stationary object
If multiple objects are present in a responder's field of view, then comprehensive scene coverage is improved, but the precision of identifying which object is being watched deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the field of view into multiple zones or regions, each associated with specific objects of interest. The gaze detection device determines which segmented region the watcher is focusing on, thereby identifying the specific object being watched even when multiple objects are present in the overall field of view. This segmentation approach maintains comprehensive coverage while achieving precise object identification.
3Device complexity
If video sources are not associated with individual responders, then device complexity is reduced, but the ability to determine who is observing what is lost
Solution Approach 1:
The patent implements self-service by enabling video sources and responders to automatically associate themselves through the gaze detection and object detection system. The communication interface allows devices to autonomously identify and link watchers with their observed objects without requiring manual association or complex configuration, thereby maintaining low device complexity while preserving watcher-object observation information.
