Abstract: Disclosed is an apparatus and method of generating a VR sickness prediction model. A method of generating a VR sickness prediction model according to the present disclosure includes: displaying virtual reality content on a display unit; detecting first VR sickness information of a user who experiences the virtual reality content using a sensor; determining second VR sickness information using a user input that is input from the user in response to a request for inputting a degree of VR sickness for the virtual reality content; performing machine learning based on supervised learning using VR sickness-inducing factors for the virtual reality content, the first VR sickness information, and the second VR sickness information; and determining a correlation between the VR sickness-inducing factors and a list of VR sickness symptoms on a basis of the performed machine learning.

Abstract: A system and a method perform buoyance of a 3D hologram image on a hologram display screen in a projection mode. A system of displaying a digital hologram includes: a composite hologram unit configured to generate a hologram array by receiving hologram data of a fringe pattern and by compositing background image and a foreground image using the received fringe pattern; a hologram projection unit configured to project a hologram image through a wide-angle lens by applying a light to the hologram array; and a hologram display unit configured to perform space buoyance of the hologram image projected by the hologram projection unit on a 3D hologram display screen. The digital hologram content is managed in real time, and transmission of the digital hologram content to a remote place and site adaptive display of hologram image media may be achieved.

Abstract: Provided is a method of generating multi-view immersive content. The method includes obtaining a multi-view background image from a plurality of cameras arranged in a curved shape, modeling the obtained multi-view background image to generate a codebook corresponding to the multi-view background image, obtaining a multi-view image including an object from the plurality of cameras and separating a foreground and a background from the obtained multi-view image by using the generated codebook, and synthesizing the object included in the separated foreground with a virtual background to generate multi-view immersive content.
