Why does it say No Face Detected even if the results show a face?

Sometimes, you may see the AutoProctor report show a No Face Detected violation, even though in the evidence there is actually a face! This sounds counter-intuitive because to our human eye, there is obviously a face right there. But, remember that AutoProctor uses AI to detect if there is a human face. And, AI isn't 100% accurate!

This is also the reason we provide evidence to violations that you see—so that you can judge for yourself if the AI's detection is correct. A few reasons why the AI may say there are no faces (called a false positive) are:

The test taker isn't looking at the screen directly. They are maybe looking away or looking down
The user is wearing reflective glasses (so the eyes aren't clearly visible)
The user isn't against a plain background and so the AI cannot easily detect the face from the background

There may be other reasons apart from this as well. Also, this is why we say that you should always look at the full report to judge whether the test taker cheated or not. DO NOT judge only on the basis of the Trust Score.
