  • Patent number: 12086335
    Abstract: The present disclosure related to a method for playing a multidimensional reaction-type image. The method includes at least: receiving, by a computer, input manipulation to an object from a user; and extracting, by the computer, an image frame matched to a detailed cell corresponding to location information and depth information in a reaction-type image, depending on the location information and the depth information of the input manipulation received at each playback time point. The depth information is information about pressure strength of the input manipulation applied to the reaction-type image or time length to which the input manipulation is applied. The location information is information about a location of a two-dimensional space in which the input manipulation is applied to the reaction-type image.

  • Publication number: 20230319375
    Abstract: The inventive concept relates to a method for producing a multi-reactive video and providing a multi-reactive video service, and a program using the same. It is possible to grasp a user's reaction to a video by recording manipulation details for a specific user's multi-reactive video. For example, it is possible to grasp the object of interest and the degree of interest of a user and to grasp a user interest in the user, by grasping the number of touch manipulations to the user's multi-reactive video, a frame in which a touch manipulation has been performed, and an object in the frame, or the like.
