In this paper, we propose digital exhibition contents for the aquarium, especially 'Gyeongpo Lagoon Ecological Museum'. We try to plan appropriate media contents that can be mixed with the aquarium storytelling. The aquarium must have special spaces that are not related with an exhibition directly but are necessary for survival of fishes such as a water circulation room. We design the special spaces using media contents and let visitors feel that the whole aquarium is in the ocean. First of all, we investigate the aquarium currently under construction. And then, we propose the appreciate media platforms and plan individual content. We suggest 3 types of media platforms, 3D water projection, interactive games utilizing Kinect, and a fog screen. Moreover, we produce 2D drawing concepts, 3D modeling images, and virtual exhibitions in virtual reality for the representation of the location in which those platforms are installed and the media contents we plan. The pre-visualization is helpful for the media platform construction and is used as a rough sketch to producing an animation shown in the exhibition.

This paper describes the development of the 3DDAC mk.4 system, which is a brand new implementation on the research program. The 3DDAC is a fatigue-less stereoscopic display system that is provided with a compensating function of accommodation for binocular disparity 3D image representation. The mk.4 system also features a light-weight HMD style.

This paper describes a hybrid gesture interface based on MediaPipe that recognizes facial gestures and hand gestures using the MediaPipe Hands model and MediaPipe Face Mesh model, and then combines them. First, the presence of hands and faces is determined by individually detecting 3D hand landmarks of MediaPipe Hands model and 3D face landmarks of MediaPipe Face Mesh model from camera input frames, and then the face cursor position and face gestures, as well as the hand cursor position and hand gestures are recognized. Then, these are mixed in a user-friendly way to implement a user interface based on hand-face hybrid gestures. The proposed hand-face hybrid gesture interface based on MediaPipe has the advantage that the gesture mode is set to either the hand or the face, but the interface can be controlled freely using the face and hands without additional gestures for mode switching. In addition, the practicality and usefulness of the proposed hand-face hybrid gesture interface were confirmed through software operation experiments in Windows environment.

A HEVC-compatible 3D video coding method (3D-HEVC) has been recently developed as an extension of the high efficiency video coding (HEVC) standard. In order to efficiently deal with the multi-view video plus depth (MVD) format, 3D-HEVC exploits an inter-component prediction which allows the prediction between texture and depth map images in addition to a temporal prediction used in the conventional single layer video coding such as H.264/AVC and HEVC. The performance of the inter-component prediction is normally affected by the accuracy of the disparity vector, and thus it is important to have an accurate disparity vector used for the inter-component prediction. This paper, therefore, introduces a disparity derivation method and inter-component algorithms using the disparity vector for the efficient 3D video coding. Simulation results show that the 3D-HEVC provides higher coding performance compared with the simulcast approach using HEVC and the simple multi-view extension (MH-HEVC).
