Exams with Invigilation Features

Facial Recognition

Facial recognition is a way of identifying key features on a person's face and using it as a way to identify and differentiate between people. You will be met with a message if a flow has been set up with facial recognition.

When you enter a flow with facial recognition on, it will then be required to take a picture with either the integrated webcam on a laptop or by having an external webcam connected to the computer or laptop.

  1. Take Image: This is the button to press to take the image that will be used for the facial recognition of the participants. You can adjust the size of the window on your screen by using the dropdown menu to the left of it.
  2. Choose Webcam: This dropdown menu becomes available should the participant have multiple webcams available to take the image with.

    External webcams have to be plugged in before starting the flow, otherwise it will not register.

  3. Corner menu: By pressing this button, you get two different options:
    • You can either exit the browser on your own, or
    • you can skip the facial recognition process by having an invigilator use their password to allow you to skip.

After taking the photo, you will get the option to either retake the image or confirm this is the image you want to use. Doing so will add the face to an archive for facial recognition. Your very first image will be used to cross-examine all future images taken for future flows.

If multiple faces appear on a picture, facial recognition will make use of the largest face in the frame, which will almost always be the closest face as well, and match this to the reference picture.

Voice Detection

Voice detection is a way of using the microphone on your computer to capture audio during a lockdown exam. You will be met with a message if a flow has been set up with voice detection.

When you enter a flow with voice detection on, you can setup your microphone before you enter the lockdown exam.

    • you can either exit the lockdown browser.

  3. Ensure your microphone is working: You can determine that your microphone is working correctly when the bar is moving and turning green when you are speaking. You can then speak out your name and
  4. Confirm your set up. The button will only turn green when the microphone has picked up any sound. 

When you are in the lockdown browser, a small camera and/or microphone icon will indicate that this flow is using invigilation features as facial recognition and/or voice detection. The system will capture images and/or audio in the background.
