Effects of Video Expression in Videoconferencing

摘要

The impression of video is dependent on its expression. This has not been addressed very much in the context of the research on videoconferencing and can be used in videoconferencing. The experiment was conducted to know the video expression that suits to a certain type of meeting. The videos that were made up of the combination of 3 visual elements of 2 choices each were shown to 207 college students and were evaluated by questionnaires. Analyses were made in 3 steps to examine the characteristics of each video, the relation between the elements and the evaluation of questions, and the contents of the questions. From the evaluation, principles to use appropriate video in certain types of meeting were suggested.
