A System for Synchronous Distance Learning
نویسندگان
چکیده
Providing an effective mechanism for an instructor to interact with one or more remote classrooms is a complex problem in synchronous distance learning. Although a human operator at the remote classroom could be used to direct a video camera and hence provide feedback to the instructor as to the state of the class and to coordinate the instructor’s attention to the class as questions are raised, more automated techniques are desirable. Here we describe a novel audiovisual sensor to support distance learning. This sensor provides the instructor with a panoramic view of the class and can automatically attend to students who signal their intent to interact with the instructor either by raising their hand or by asking a question vocally. This paper describes the sensor and the user interface that is provided to the instructor so (s)he can interact with the students in the remote class.

Introduction: With the arrival of new communication technologies, the process of learning from the teacher to the learner’s pivot with emphasis on the centrality of the learner has an independence movement and in determining the methods of teaching and assessment practices. On this basis the independence of the learner is one of the fundamental concepts of remote education system. The aim ...
