Trends and Developments from the VR2007 Conference

2001

SUMMARY Research in virtual reality (VR) is a relatively young field, which has shown considerable growth in recent years, as the development of new interactive technologies has inevitably impacted the more traditional sciences and arts. This is more evident in the case of novel interactive technologies that fascinate the broad public, as has always been the case with virtual reality. The increasing development of VR technologies has matured enough to expand research from the military and scientific visualization realm into more multidisciplinary areas, such as education, art and entertainment. Consequently, virtual reality interfaces interaction techniques and devices have improved greatly in order to provide more natural and obvious modes of interaction and motivational elements. In spite of various concerns and objections regarding the appropriateness and educational efficacy of virtual reality, there remain compelling reasons for believing that virtual environments warrant serio...

What can Virtual Reality and Augmented Reality technologies do for us? Can they help us make better use of computers? Will they ever improve the quality of our personal lives? What kind of immersive interfaces could re-shape the way we communicate with computers? How far along are we on that road, and what remains to be done? This is only a small selection of the questions discussed at the workshop on the future of VR and AR interfaces at IEEE Virtual Reality 2001. Main areas of focus were conversational user interfaces, natural ...

This report documents the program and the outcomes of Dagstuhl Seminar 13241 “Virtual Realities”. The main goal of the five day seminar was to bring together leading experts and promising young researchers to discuss current challenges and future directions in the field of virtual and augmented reality. The seminar was organized as series of individual presentations and seven working groups. Abstracts of the presentations and working group reports are collected in this report. Seminar 09.–14.

Abstract. User interface (UI) design is a critical component of any virtual environment (VE) application, and especially for VE applied to medicine. User interfaces for VE are becoming more diverse. Mice, keyboards, windows, menus, and icons-the standard parts of traditional WIMP interfaces-are still prevalent, but nontraditional devices and interface components are proliferating rapidly. These include spatial input devices such as trackers, 3-D pointing devices, and whole-hand devices allowing gestural input.

The motivation for this workshop was to create shared understanding between the Virtual Reality (VR) and Web3D communities. While the two fields of Web-based 3D graphics and VR 3D graphics have tended to view their technology as different beasts, they have many of the same requirements regarding virtual world content: modeling, lighting, animation, interaction, and direct manipulation. This workshop focused on common interests regarding the seamless access and delivery of interactive, network-based VR content and resources. Presentations and discussions looked at the philosophies and feature sets of various scene graph tools, including ISO-based scene-graph standards such as X3D/VRML in immersive contexts. The principal thematic question examined was: what are common requirements for a data archive format that provides expressive run-time application behavior? Through multiple tool and application examples, contributors examined commonalities and differences between these two important communities, and developed a workable roadmap of cross-community education and common effort.

As collaborative VR for learning is coming to the general market, its evaluation in situ becomes more pregnant. Our purpose is: 1) implement collaborative VR for learning in situ in various conditions, 2) propose a questionnaire-based method to evaluate Quality of Experience (QoE) and 3) identify potential parameters influencing QoE. 88 participants divided into 4 groups completed questionnaires after participating to different VR activities. Our results show that QoE is influenced by the technical specificities of the Head Mounted Display as well as by the learning instructions and materials but not by the relative locations of the users (distant or sharing the same physical space). We suggest that trainers should take advantage of Collaborative VR in the design of the training activities to support interactive and trainee-centered approach. Presence, Flow, Visual Discomfort, and User eXperience can be considered as a minimum way to proof base the quality of deployment.

In today's world we are surrounded by a wonderful array of technologies. We have assimilated many of these technologies into our everyday lives. Increasingly, these different technologies are becoming integrated to provide new capabilities and services. And most frequently a computer is the heart of this integration. This is the case with Virtual Reality-a so-called technology which actually is a very sophisticated integration of a number of technologies.Virtual Reality (VR), sometimes called Virtual Environments (VE) has drawn much attention in the last few years. Extensive media coverage causes this interest to grow rapidly. Very few people, however, really know what VR is, what its basic principles and its open problems are. In this paper aoverview of virtual reality is presented, basic terminology and classes of VR systems are listed, followed by applications of this technology in science, work, and entertainment areas. An insightful study of typical VR systems is done. All components of VR application and interrelations between them are thoroughly examined: input devices, output devices and software. Additionally human factors and their implication on the design issues of VE are discussed. Finally, the future of VR is considered in two aspects: technological and social.

In this paper, we describe a user interface technique that uses a bounding box as a m taphor to facilitate interaction in a Virtual Reality (VR) environment. Because this technique is based on the observation that some of the VR application fields are contained in a closed world, we call it Closed World Interaction (CWI). After the user defines a closed world, the necessar virtual buttons are shown around the closed world which is presented by a fi'ame. These virtual buttons are then used to interact with models. We also integrate some of the 2D Windows, Icons, Mouse and Pointer (WIMP) metaphors into CWI technique, reflecting our belief that users will be able to adapt to this environment quickly, A series of user studies were conducted to investigate the effectiveness of this technique. The results indicate that users can define a closed world quickly. Experience appears to be an important factor, and users can be trained to become familiar with CWI in the VR environntent. The constrained interactions can also enhance the accuracy of selection. Two-handed manipulation somewhat improves the speed.

The advancement of recent developments over the VR with the expansion of new Head Mount Displays (H.M.D.) such as Oculus Rift and Morpheus have opened new challenges in the already active research filed of the industry of Human-Computer Interaction (HCI) by exploring new means of communication with the support of the new hardware devices adjustable to body movements and hand position. The paper explores the hardware interactivity and VR H.M.D's through two games designed to use the latest Oculus Rift SDK technology with alternative methods of hardware communication. A usability evaluation study was conducted with 18 participants and the results presented and discussed.
