Nestor AI (also known as Nestor) is an artificial intelligence program and e-learning class assistant, created by Dr. Marcel Saucet and developed by Nicolas Delhaume.

Description
The assistant was created as an artificial intelligence and facial analysis program and applies advanced natural language processing, information retrieval, automated reasoning, and machine learning technologies.

The software determines whether students pay attention in class by tracking their eye motions and facial expressions through webcams. When the student watches a video lecture, the artificial intelligence, by the sensor of the webcam and a system of facial recognition, records the movements and reactions of the student. After class, students are quizzed on the lesson, which also include questions from parts of the lesson that they did not pay attention to.

Software

The software incorporates machine learning algorithms to improve tool performance and make it more precise.

Data

The software decodes student’s minds by detecting 20 parts of their faces through webcams while they watch the lectures. There are 20 key markers on the user's face that is analyzed by the artificial intelligence software: eyes, eyebrows, lips, jaw, etc., and Nestor can understand how the user behaves in front of the video lesson. All the data that is collected is encrypted and anonymous.

Operation
The artificial intelligence in this software program predicts future inattentiveness by studying the student's past behavior. For example, "if a ... student tends to wander off after 2 minutes and 30 seconds into the lecture, Nestor sends a notification, which will appear on the screen, 10 seconds before that timestamp to warn the student." This software determines when a student becomes inattentive. The assistant alerts students in advance to stay focused during the lecture. This program enables teachers to improve their lectures.

Application

Two online classes from the ESG Business School used Nestor to measure student's attentiveness and engagement.
