Gangwon-do is a representative leisure resort. However, the provision of tourism information has not escaped the existing image- and text-oriented simplicity. Therefore, a linkage strategy for the content business is needed to revitalize tourist attractions. In this paper, first, we provide a 360-degree rotating VR content authoring function. Second, we propose a dynamic platform including a function that allows users to easily author tour scheduling after registering VR content on a map. Finally, the proposal system provides pre-tourism customers with an opportunity to increase satisfaction by providing online pre-experience.

Multimedia services through a network are getting more required according to the realization of B-ISDN construction globally. Business using the Internet will become popular, and so multimedia information systems including telemarketing systems will be developed competitively. VR (Virtual Reality) will help such systems make more realistic and valuable. ln this paper, we present an interactive VR authoring tool and a client/server based multimedia information service system. The VR authoring tool serves an interface with the system when developing its applications.

가상 현실의 궁극적인 목표중의 하나는 참여자가 가치 있는 경험을 얻을 수 있도록 하는 것이다. 경험의 내용은 순차적인 이벤트들로서 구성될 수 있으며 본 논문은 이런 이벤트들을 저작(event authoring)하기 위한 알고리듬을 개발하는 것을 목적으로 한다. Event authoring을 위해서 우리는 우선, 가상환경에 포함되는 개체들의 구조를 제안한다. 그리고, event-program을 기술하여 실험을 행할 수 있게 하는 수단인 event authoring language와 event-program 실행 시에 핵심이 되는 event execution manager를 구현한다. 마지막으로, 몇 가지 실험을 통하여 본 논문에서 제시된 접근방법이 유효함을 증명한다.

This paper describes a new visual VR authoring tool called DEVISE (Drawing Environment for VR-based Inquiry-learning Science Education) which is designed to support scientific inquiry learning. DEVISE allows users with no programming expertise to easily build the science inquiry learning VR contents by using 2D drawing interface to place 3D objects and specify properties of the virtual worlds or objects. This paper first describes the related works of VR authoring tools and inquiry learning virtual environments. It also explains SASILE, an integrated virtual environment system for supporting science inquiry learning, and its problems. Then, it describes DEVISE system components and its workflow, and it discusses the observation results of user evaluations of developing science inquiry-learning VR contents.

In this paper we propose a VR-based Sailor Training Platform Authoring Tool which efficiently trains sailors in immersive ways. Proposed authoring tool consists of virtual environment reconstruction that imports real ship indoor environment into virtual environment and script editing which is able to implement various scenarios in emergency based on just drag-and-drop interface. The aim of importing real ship environment and supporting various VR devices is to enhance immersiveness and training so that trainees can deal with serious emergency events. Also the usefulness of the interface enables to reduce the cost of making training materials. Throughout scenario editing interface, the proposed authoring tool supports the editing of multi-user scenario and setting individual task for the evaluation.

This research studies the Virtual Reality simulation of Newton's physics law on rigid body type of objects for physics learning. With network support, collaborative interaction is enabled so that people from different places can interact with the same set of objects in Collaborative Virtual Environment. The taxonomy of the interaction in different levels of collaboration is described as: distinct objects and same object, in which there are same object - sequentially, same object - concurrently - same attribute, and same object - concurrently - distinct attributes. The case studies are the interaction of users in two cases: destroying and creating a set of arranged rigid bodies. We identify a specific type of application for contents authoring with modeling systems integrated with real-time physics and implemented in VR system. In our application called Virtual Dollhouse, users can observe physics law while constructing a dollhouse using existing building blocks, under gravity effects.

We are suggesting an authoring tool can be used for prototyping in the augmented reality based product design environment. This tool is for authors without an engineering background to use. Our authoring tool can adjust the properties of visual, sound, and haptic feedback at the same time for more practical prototyping. Also the proposed modulated architecture can be applied flexibly to changes of platforms or hardware. Also user interfaces can be dynamically updated by changing just description files. finally, the suggested authoring methods exploit the advantages of both graphical and tangible user interfaces. Authors can intuitively make adjustments to many parameters using the TUI, and then they can do the same thing precisely using the GVI. The proposed authoring methods can be used for exhibition and entertainment contents using multi-sensory feedback in AR environment. As a future work, qualitative and quantitative usability test will be conducted.

This study is about the Novel Engineering(NE) education program : a class model that combines reading and engineering. By including the process of directly designing and programming a virtual reality using CospacesEdu (a VR authoring tool for the NE class), the effects of the educational program on learners' STEAM literacy and Learning immersion are demonstrated. Moreover, the subject of this education is Dokdo in South Korea. As a result, the average of STEAM literacy is increased, and a significant change is confirmed statistically in Convergence. Learning immersion shows significant improvement in Challenges-skills balance. On the other hand, some students experience difficulties due to the long research stages, from reading a book to researching for information to designing VR and rewriting a story with the collected information. In conclusion, this study will help generalise other education using NE, and this developed program will be a reference that would suggest a new way of teaching.

Authoring AR(augmented-reality) contents not only takes too much time and cost, but also needs the help of professionals in the areas of computer science, VR(virtual reality), AR, 3D computer graphics, computer vision, etc. This paper proposes an authoring tool to allow non-programmers as content creators to author AR contents easily and quickly. An ideal AR authoring tool, which is the goal of our research, faces four major challenges from a technical point of view: (1) easy and quick authoring, (2) strong power of expression, (3) ease of verification and validation, (4) interactive authoring and debugging. To tackle with the challenges, we employ the interactive framework approach using formal and visual specification techniques.

Although most of all modern Web contents accomplished by passive interface which used 2D, by way of developing super-highway internet net and a 3D compression technology, it gradually changed VR Web3D. In this approach, we presents a recently VR tech. as well as the implementation of Web3D based on VR mapping tools.
