The description of an abstract concept refers to the scope of the content that such concept encompasses,

specifically, assuming that the range of the user visual region passing through within 1 second is 0.2 m, it is stated that the vibration frequency of the user visual region is 5 times per second, and then the vibration frequency of the video is also 5 times per second.

It can be understood that the vibration amplitude of the user visual region is positively correlated with the vibration amplitude of the video, that is, the larger the vibration amplitude of the user visual region is, the larger the vibration amplitude of the video is, and the larger the vibration frequency of the user visual region is and the vibration frequency of the video, that is, the larger the vibration frequency of the user visual region is, the larger the vibration frequency of the video is.

And finally, the display adjusting device vibrates the space in the first playing content and the vibration buffer area of the playing window according to the vibration frequency of the video, so that the first playing content and the vibration buffer area are combined into second playing content through vibration. Assuming that the vibration frequency is 4 times per second, the first playing content should also be vibrated with the frequency of 4 vibrations per second, and the limit of each vibration is the limit endured by the vibration buffer.

Furthermore, in the embodiment of the present invention, how to adjust the first playing content to be displayed to obtain the second playing content is described, the first playing content is set to be in the window playing mode, then the vibration buffer areas are set above and below the playing window, and finally the first playing content is vibrated in the playing window and the vibration buffer area according to the vibration frequency of the video to obtain the second playing content.
