Gaze and Head Movement
The signal most systems lead with, the one with the weakest link to misconduct, and the source of most of the unfair flags.
Analysis
What is detected
Each signal has ordinary explanations, and the weakest ones generate the most flags.
6 notes
Audio and Background Noise
Sound detection captures the student's home and everybody in it. The signal is more informative than gaze and the intrusion is larger.
Analysis
Second Devices and Screen Sharing
The largest unsolved gap in remote assessment, the measures that address it partially, and the ones that are theatre.
Analysis
Room Scans
The student is required to show their room on camera before the exam. The most contested single practice in proctoring, and the one most likely to be challenged.
Analysis
Keystroke and Behaviour Analysis
Modelling how a student types and moves, and comparing it against a baseline. The most technically ambitious signal and the least supported.
Analysis
What None of It Sees
The channels no proctoring arrangement closes, which matter because they are the ones a determined student uses.
