Multi-Camera Proctoring System for Exam Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for proctoring computerized tests are inadequate in preventing cheating, as they rely on single camera views that can be easily circumvented by examinees.
Innovation Solution
A proctoring system that employs two digital proctoring cameras positioned to capture video of the examinee's keyboard and face/hands, as well as the monitor screen and surrounding desk area, with the cameras communicating digitally to a proctor monitoring system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single webcam is used for proctoring, then the system is simple and easy to operate, but it can be easily circumvented by examinees through camera angle adjustment
Solution Approach 1:
The proctoring system is segmented into multiple independent camera units, each capturing specific areas (face, hands, keyboard, desk). This segmentation ensures that no single camera can be circumvented to achieve complete cheating, as each camera monitors a distinct zone that would require multiple coordinated actions to bypass.
Solution Approach 2:
The system transitions from a single-point camera view to multi-dimensional spatial monitoring by positioning cameras at different locations and angles. This dimensional expansion creates overlapping fields of view that cover the entire testing area, making it impossible for examinees to find blind spots or adjust a single camera angle to cheat.
2Reliability
If multiple cameras are deployed to capture comprehensive views, then cheating detection capability improves, but system complexity and setup difficulty increase
Solution Approach 1:
Each camera in the system is designed to serve multiple functions simultaneously. For example, the first camera captures both the examinee's face and hands, while the second camera captures both the keyboard and desk area. This multi-functionality reduces the total number of cameras needed and simplifies setup procedures.
Solution Approach 2:
The patent combines multiple monitoring functions into a unified proctoring system where cameras, software, and processing work together as an integrated whole. The proctoring software merges video feeds from multiple cameras into a single comprehensive view for the proctor, simplifying operation despite the multiple physical cameras deployed.
3Measurement precision
If comprehensive multi-camera monitoring is implemented, then the ability to detect suspicious behavior improves, but the cost and resource requirements increase
Solution Approach 1:
Instead of uniformly distributing camera coverage, the system applies local quality by concentrating monitoring resources on specific high-risk areas. The first camera focuses on the examinee's upper body, face, and hands where cheating behaviors like looking at notes or using unauthorized devices occur. The second camera focuses on the keyboard and desk area where answer copying or device usage might happen. This targeted approach achieves high detection precision with fewer cameras.
Data Source
AI summary
A system and a method of using the system for proctoring of a computer administered exam or test. The proctoring system includes software and at least two digital proctoring cameras arranged to capture at least: strokes on a keyboard, information displayed on a monitor, and activities of the examinee. The system can additionally capture video of the environment surrounding the testing computer, including monitoring and/or recording of activities on ancillary computing/communication devices located in the test environment. The information can be time stamped enabling synchronization thereof. The collected information is forwarded to a proctoring system, which can include artificial intelligence software to aid in monitoring the administration of the tests. A privacy screen can be employed to limit a viewing angle of the screen. The system includes a function of monitoring ancillary electronic devices, including management, monitoring, and/or recording of activities thereon.
