Abstract—The demand for live music video has been increasingly reported. To bring high satisfaction to the users, it is necessary to improve the presence experience while watching the videos. Our previous study introduced a method which suddenly performs a zooming operation to the video frame where a high intensity of motion is detected, resulting in better presence. However, such a sudden zooming operation makes the users feel uncomfortable, leading to low score of pleasure. In this paper, two types of adaptive zooming operations are proposed not only to enhance the presence experience but also to eliminate such an uncomfortable feeling. One adapts zooming magnitude to the intensity of motion. The other adapts zooming speed to human’s visual perception, that is to say, the zooming is performed gradually. The experimental result shows that the proposed operations outperform the previous simple zooming operation in terms of the presence experience and comfortability.
