Video Task Verification Using ROI Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for systems and methods to monitor and verify employee task completion in retail or service environments using video capture systems, while effectively detecting employee-provided task completion signals to update schedules and alert managers.
Innovation Solution
A video system with cameras monitoring a region of interest (ROI) analyzes pixels in video frames to detect employee signals, identifies corresponding tasks, updates task schedules, and generates alert messages upon task completion, utilizing techniques like hand gesture recognition and image processing to classify signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual task reporting is used, then employees can report task completion, but it requires manual intervention and is time-consuming
Solution Approach 1:
The patent replaces the manual mechanical reporting system with an automated optical detection system. Video cameras capture employee gestures (hand signals, finger counts) and the system automatically interprets these visual signals to update task schedules, eliminating the need for manual reporting and significantly reducing time consumption.
Solution Approach 2:
The system enables employees to self-report task completion through simple gestures captured by video cameras. The automated recognition and processing of these gestures allows the system to update task statuses without requiring employees to manually input data or interact with complex reporting interfaces.
2Reliability
If video capture systems are deployed for monitoring, then task completion can be tracked, but system complexity increases
Solution Approach 1:
The patent extracts and isolates specific gesture recognition patterns (hand signals, finger counts) from the complex video data stream. By focusing detection efforts on predetermined, easily identifiable gestures within defined regions of interest, the system achieves reliable task verification without requiring complex analysis of entire video feeds.
Solution Approach 2:
The system changes the parameter of employee interaction from complex verbal or written reporting to simple, standardized hand gestures. This parameter change simplifies the detection task for the video system, as gestures can be reliably identified through basic image processing and pattern recognition algorithms.
3Productivity
If automated signal detection is implemented, then task verification is improved, but detecting employee signals accurately becomes more difficult
Solution Approach 1:
The system performs preliminary actions by establishing predetermined associations between specific gestures and task completion signals before actual task verification begins. Employees are trained on standardized gestures, and the system is pre-programmed with the corresponding interpretations, making accurate detection straightforward during operation.
Solution Approach 2:
The patent segments the monitoring area into specific regions of interest (ROIs) where gestures are expected to occur. By focusing analysis on these predefined spatial segments rather than the entire video feed, the system improves detection accuracy while reducing computational complexity.

AI summary
When monitoring a workspace to determine whether scheduled tasks or chores are completed according to a predetermined schedule, a video monitoring system monitors a region of interest (ROI) to identify employee-generated signals representing completion of a scheduled task. An employee makes a mark or gesture in the ROI monitored by the video monitoring system and the system analyzes pixels in each captured frame of the ROI to identify an employee signal, map the signal to a corresponding scheduled task, update the task as having been completed upon receipt of the employee signal, and alert a manager of the facility as to whether the task has been completed or not.
