Development of Video Presentation Mutual Evaluation Support System with Portable Mobile-Devices using Drag and Drop Evaluation Function

Abstract

The purpose of this study is to introduce a portable mobile-device learning environment that realizes accurate evaluation communication for presentation rehearsal. To accomplish this, we developed a Video Presentation Mutual Evaluation Support System (VPE system) with a Drag and Drop (D&D) evaluation function. In the D&D evaluation function, the reviewers drag and drop a marker (the evaluation marker) onto a slide on a video presentation, for accurate evaluation communication. We conducted an evaluation experiment using the VPE system on university students, and verified its function through a questionnaire. The results reveal that the D&D evaluation function can convey accurate timing and accurate position information from the reviewers using the evaluation marker. Further, it was revealed that the D&D evaluation function is easy to operate.
