Method of real-time supervision of interactive online education

A method of real-time supervision of interactive online education, the method to be implemented by an online education system, the online education system including a teacher-end device that displays course material for viewing by a teacher, a student-end device that displays the course material for viewing by a student, and a server that is communicably connected with the teacher-end device and the student-end device via a communication network, the teacher-end device continuously capturing a first image of a space where the teacher is located to result in first image data, and transmitting the first image data via the communication network to the server in real time so as to enable the server to transmit the first image data via the communication network to the student-end device in real time for display of the first image by the student-end device, the method comprising:

• by the server, when it is determined based on the first image data received from the teacher-end device that the first image contains an image portion which corresponds to a body part above a chest of the teacher, determining whether one of a facial expression, a facial movement, a face position, and a body portion between a chin and the chest of the teacher satisfies a first predetermined condition by performing image recognition on an image data portion of the first image data which corresponds to the image portion;
• and
• by the server, when it is determined that one of the facial expression, the facial movement, the face position, and the body portion between the chin and the chest of the teacher satisfies the first predetermined condition, transmitting a first notification message which is associated with the first predetermined condition via the communication network to the teacher-end device for output of the first notification message by the teacher-end device.
