Face-to-face telepresence promotes the sense of ”being there” and can improve collaboration by allowing immediate understanding of remote people’s nonverbal cues. Several approaches successfully explored interactions with 2D content using a see-through whiteboard metaphor. However, with 3D content, there is a decrease in awareness due to ambiguities originated by participants’ opposing points-of-view. In this paper, we investigate how people and content should be presented for discussing 3D renderings within face-to-face collaborative sessions. To this end, we performed a user evaluation to compare four different conditions, in which we varied reflections of both workspace and remote people representation. Results suggest potentially more benefits to remote collaboration from workspace consistency rather than people’s representation fidelity. We contribute a novel design space, the Negative Space, for remote face-to-face collaboration focusing on 3D content.

We are very glad to host VRCAI2009 in Japan and welcome you to Tokyo Institute of Technology which is a very active university in VR, CG and Image processing fields. Virtual Reality Continuum (VRC), which spans across next-generation info information communication environments, like Virtual Reality (VR), Augmented Virtuality (AV), Augmented Reality (AR), and Mixed Reality (MR), is a key in the way we define and interact with, and within, our virtual worlds. To advance research in the VRC field, the VRCAI conference seeks to provide a forum for scientists, researchers, developers, users and industry players in the international VRC community to come together to share experiences, exchange ideas and spur one another in the knowledge of this fast-growing field. This year, VRCAI 2009 focuses on the following themes: Fundamentals, Systems, Computer Graphics, Image Processing, Interactions , and Industry and Applications. A new focus area on Computer Graphics and Image Processing related to Virtual Reality has been introduced. We see the importance of CG and image processing for developing VR systems and applications growing more and more. Especially, VRCAI2009 is held just 2 days before SIGGRAPH ASIA 2009. VRCAI and SIGGRAPH ASIA should be more strongly connected each other. So, we hope VRCAI welcomes the papers in the fields of CG and Image Processing. Since its beginning as the 1st International Workshop on Virtual Reality and Visualization in Scientific Computing held in Hangzhou, China in 1995, VRCAI has grown and matured into a reputable biennial conference. Selected papers from past VRCAI conferences have been published in special issues of Computers & Graphics journal, International Journal of Virtual Reality, International Journal of Image and Graphics, and Computer Animation and Virtual Worlds. Since 2004, the conference has been indexed by EI. It has been also co-sponsored by ACM SIGGRAPH, and its papers included in the ACM Digital Library. The 8th VRCAI 2009 conference attracted 98 submissions from 17 countries in Europe, North and South America and Asia. The submissions were reviewed by about 70 reviewers, with each full paper receiving at least three reviews. The papers were of high quality and very competitive. 40 submissions have been accepted as full papers and 29 as poster papers.
我们非常高兴在日本举办VRCAI2009，并欢迎您来到东京工业大学，这是一所在VR, CG和图像处理领域非常活跃的大学。虚拟现实连续体(VRC)跨越下一代信息通信环境，如虚拟现实(VR)、增强虚拟(AV)、增强现实(AR)和混合现实(MR)，是我们定义虚拟世界、与虚拟世界互动以及在虚拟世界中互动的关键。为了推进VRC领域的研究，VRCAI会议旨在为国际VRC社区的科学家、研究人员、开发人员、用户和行业参与者提供一个论坛，让他们在这个快速发展的领域分享经验、交流想法并相互激励。今年，VRCAI 2009重点关注以下主题:基础、系统、计算机图形学、图像处理、交互以及工业和应用。介绍了与虚拟现实相关的计算机图形学和图像处理的新重点领域。我们看到CG和图像处理对于开发VR系统和应用程序的重要性越来越大。特别是，VRCAI2009在SIGGRAPH ASIA 2009前两天举行。VRCAI与SIGGRAPH ASIA之间的联系应该更加紧密。因此，我们希望VRCAI欢迎CG和图像处理领域的论文。自1995年在中国杭州举办的第一届科学计算中的虚拟现实与可视化国际研讨会开始，VRCAI已经成长为一个两年一度的知名会议。历届VRCAI会议的论文已在《计算机与图形学》杂志、《国际虚拟现实杂志》、《国际图像与图形杂志》和《计算机动画与虚拟世界》特刊上发表。自2004年起，会议被EI收录。它也被ACM SIGGRAPH共同主办，其论文被纳入ACM数字图书馆。第八届VRCAI 2009会议吸引了来自欧洲、北美、南美和亚洲17个国家的98份意见书。提交的论文由大约70位审稿人审阅，每篇论文至少接受三次审稿。论文质量很高，很有竞争力。40份提交的论文被接受为全文论文，29份被接受为海报论文。
