 note = {ビデオには動きと外見の二つの情報が含まれる．我々は，相手のビデオ （動き＋外見），アバタ （動き） または写真 （外見） を提示した音声会話と，何も提示しない音声会話を比較する実験を行った．被験者の発話中の途切れを数えた結果，実験者の動きが伝わると被験者の途切れの数は減少していたが，外見の欠落は途切れの数に影響しなかった．この結果は，音声会話をなめらかにするためには動きの伝達が重要であり，アバタがビデオを代替しうる可能性を示している．, Videos include two kinds of information, the remote person's motion and appearance. We conducted an experiment in which the subjects watched a remote person's video, avatar, photo, or nothing when speaking to the person. As a result of counting the number of pauses included in the recorded speeches, we found that the presentation of motion reduced the number and the absence of the appearance did not affect it. This indicates that motion is enough to smoothen audio communication, and also implies the capability of avatars to serve as a substitute for videos.},
