In this paper we propose a touch enabled video player system. A conventional video player only allows viewers to passively experience visual and audio media. In virtual environment, touch or haptic interaction has been shown to convey a powerful illusion of the tangible nature-the reality-of the displayed environments and we feel the same benefits may be(More)
This paper presents a prototype of a client system for Realistic Broadcasting that can receive and process immersive media. It provides a viewer which supports stereoscopic video display and hap-tic interaction with the displayed media. The structure of the system is introduced and each component is described. In order to show the feasibility of Realistic(More)
In multi-modal interactions including haptics, problems such as input sensor noise, temporal mismatch between graphics and haptics, and non-constant refresh rates may cause non-smooth force/torque display. This paper proposes temporal smoothing technique for haptic interaction using a sensing glove in multi-modal applications. The proposed technique employs(More)
Previous works related to texture coordinate coding of the three-dimensional(3-D) mesh models employed the same predictor as the geometry coder. However, discontinuities in the texture coordinates cause unreasonable prediction. Especially, discontinuities become more serious for the 3-D mesh model with a non-atlas texture image. In this paper, we propose a(More)
In this paper, we propose Responsive Multimedia System (RMS) for a virtual storytelling. It consists of three key components; Multi-modal Tangible User Interface (MTUI), a Unified Context-aware Application Model for Virtual Environments (vr-UCAM), and Virtual Environment Manager (VEManager). MTUI allows users to interact with virtual environments (VE)(More)
