Abstract

Provided is a method for generating stereoscopic image fedback by the interaction with a real world. Even though the method according to the related art interacts the user with the virtual object or forms the stereoscopic image without interacting with the object in the user space by controlling the virtual object using a separate apparatus, the present invention feedbacks the interaction between all the object in the user space including the object and users in the virtual space to the video reproducing system to implement a system for re-processing and reproducing the stereoscopic image, thereby making it possible to produce realistic stereoscopic image.
