Eye-Tracked Camera View Prioritization for Video Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual adjustments to prioritize camera views in real-time video surveillance systems are challenging, leading to potential loss of tracking the targeted object or person due to slow and tedious manual operations.
Innovation Solution
Implementing an eye tracking device to automatically prioritize camera views based on the operator's gaze, allowing for automatic updates and enhancements such as re-prioritization, resolution adjustment, and highlighting of objects within the camera view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustments are made to prioritize camera views, then the operator can control which camera to view, but the adjustments are slow and tedious resulting in loss of tracking
Solution Approach 1:
The system automatically prioritizes camera views by detecting operator gaze direction and autonomously adjusting which camera feed is displayed prominently, eliminating the need for manual intervention. The eye tracking device continuously monitors the operator's gaze and the system self-adjusts the camera view hierarchy based on where the operator is looking, making the interface responsive without requiring operator actions.
Solution Approach 2:
The patent replaces manual mechanical interaction (clicking, dragging, or selecting camera views) with an optical detection system (eye tracking). The eye tracking device detects gaze position optically and converts it into automatic camera view prioritization, substituting the mechanical manual adjustment process with an optical-biological sensing mechanism that is much faster and more intuitive.
2Reliability
If the operator manually switches between camera views to track moving objects, then the target can be followed, but the frequent manual adjustments increase the chance of losing track
Solution Approach 1:
The system implements continuous feedback by monitoring the operator's gaze direction in real-time and using this information to automatically adjust camera view prioritization. The eye tracking device provides ongoing feedback about where the operator is looking, and the system responds by automatically bringing the relevant camera view to prominence, creating a closed-loop control system that maintains reliable target tracking without manual intervention.
Solution Approach 2:
The eye tracking device serves as an intermediary between the operator's natural gaze and the camera view selection system. Instead of the operator directly manipulating camera selections, the gaze detection system translates natural eye movements into automated camera view prioritization, acting as a mediator that bridges human intent and system response while reducing operational complexity.
3Adaptability or versatility
If multiple camera views are displayed simultaneously, then the operator can monitor multiple areas, but the operator has difficulty keeping eyes on the target across multiple windows
Solution Approach 1:
The system dynamically adjusts the display hierarchy of multiple camera views based on real-time gaze detection. While multiple cameras remain visible simultaneously for comprehensive monitoring, the system continuously repositions and resizes camera windows based on where the operator is looking, automatically bringing the target-containing view to the foreground or center of attention. This dynamic reconfiguration maintains multi-camera versatility while easing target-following operations.

AI summary
A video surveillance method is provided that includes: displaying one or more camera views from one or more video cameras in one or more windows on a display of an operator client; detecting a gaze position of an operator viewing the display; determining a window, or a position within a window, from among the one or more windows views corresponding to the gaze position; and updating the display of the one or more camera views based on the gaze position.
