On the Design and Application of Presenting and Teaching Aided System Based on Dual-Display Technology

Abstract

In traditional learning, teachers present words or graphs to explain the teaching materials by using blackboard. In recently years, more and more teachers choose projector instead of blackboard. Teachers prepare slides before class and present the learning content to students through the computer and the projector. Teachers may forget the some details of the slides in class because the slides are prepared before class. The aided system uses the dual-display technology and can be added to PowerPoint™ by using add-in technology. Teachers can add appropriate comments in any location in slides, set speaking flow, record voice comments and so on. All content added by the system is only visible to teachers. Teachers can increase the quality of instruction because of the additional information. Students can only see the learning content without interference. This kind of system can be applied in the conferences or in the presentations.
