As a result, three kind of factors were obtained. It was guessed that the three kind of factors are the overall quality of video and sound, the quality of video, and about the silence of contents. Moreover, the realistic sensations obtained by adjective pair of “stereognostic sense” was able to be estimated with high accuracy from score of the three kind of factors.
