This paper proposes a subjective assessment method for video quality and sense of presence for 360° videos. Since it is necessary to view 360° videos with a wide field of view, we adopted a subjective assessment method that allows repeated viewing of 10 s long videos. First, by analysis of the subject's observation behavior (i.e., head movement), it was clarified that the appropriate number of observation repetitions was 2. The relationship between the video quality and the sense of presence was then quantified using the proposed method. Finally, we determined the number of subjects necessary to derive stable evaluation results.
