A Two-Way Dual-View Teleteaching System Conveying Gestures and Chalkboard Contents
Summary :
In current teleteaching systems, video conferencing systems have been used to transmit a motion video from a teacher's site. A video that captures a teacher or his or her chalkboard is transmitted to a remote site through a communication channel. Since the resolution of the video is not very high, a camera captures either a teacher or a chalkboard, but not both at the same time. Thus, remote students have difficulty in obtaining realistic sensation. Another approach to realizing teleteaching is to use a computer-based desktop conferencing system that supports a motion video and a computer-based shared chalkboard. In this approach, a teacher has to use a mouse or a handwriting tablet for input, and therefore cannot use a real chalkboard. Moreover, the teacher cannot use gestures to remote students. This paper presents a multimedia teleteaching system that integrates an electronic whiteboard with a multimedia desktop conferencing system for providing realistic sensation to remote students. The system provides two-way communication of a video and a computerized chalkboard. A teacher uses an electronic whiteboard as a real whiteboard using direct manipulation, and transmits his or her gestures to remote students by using video communication. The system provides dual views; one view is for teacher's gestures and the other is for chalkboard contents. By providing the dual views, the system can transmit teacher's gestures all the time. Since chalkboard contents are processed and displayed as computer data, students can see them clearly. With the computerized chalkboard, a teacher or a student can zoom contents, input data written on a paper using a scanner, or add annotation.
