オンラインにおける最適なコミュニケーションの検討～2D画面と3D空間での動画教材視聴における評価～

抄録

This study investigated the most suitable representation of online communications. We prepared six types of content representation to examine the degree of understanding and impression. This paper compares viewing on a 2D screen and in a 3D space, indicating that the former was easier to understand than the latter. In the 3D space, the effects of visual information other than the content and the discomfort of the audio description were disturbing the participants' concentration. Furthermore, our experiments disclosed the following findings. Their comprehension also decreased, even though the audio speed was not uncomfortable. The 3D space environment reduced the participants' interest in the content. The visually dominant person could understand the content both in 2D and 3D space. On the other hand, the hearing dominant person was particularly susceptible to the discomfort of audio description, which is auditory information in 3D space.
