美国WorldViz虚拟现实系统技术背景介绍

美国WorldViz虚拟现实系统介绍

1、制造商的科研背景和实力

1）公司背景：美国WorldViz公司起源于美国加州大学虚拟环境与行为研究中心，公司CEO Andy Beall就是该研究中心主任。该实验室主要致力于心理认知相关的科学研究，包括社会心理学、视觉、空间认知等。具有科研背景和实力，并以用户和自身的科研需求来指导虚拟现实设备的研发和生产，因此该公司的虚拟现实软硬件平台更适合科研领域。

2）技术实力：该公司拥有一个专业的技术支持队伍，可以为科研用户提供优良的技术服务，并提供科研应用方面的咨询服务，帮助用户与国内外同行建立联系与合作。我们每年要在国内举办虚拟现实技术培训班，对老用户进行免费培训并提供科研交流的平台。

2、WorldViz虚拟现实系统在科研领域的广泛应用

其用户遍布各个应用领域，包括教育和心理、培训、建筑设计、军事航天、医疗、娱乐、图形建模等。同时该产品在认知相关的科研领域更具竞争力，在欧美和国内高等学府和研究机构拥有五百个以上用。

1）、加州大学圣巴巴拉分校虚拟环境与行为研究中心

空间认知等，并有大量论文在国际知名刊物发表，具体详见论文列表。

2）、迈阿密大学心理与计算机科学实验室

研究领域：空间认知

Human Spatial Cognition In his research Professor David Waller investigates how people learn and mentally represent spatial information about their environment. Wearing a head-mounted display and carrying a laptop-based dual pipe image generator in a backpack, users can wirelessly walk through extremely large computer generated virtual environments. Research Project Examples Specificity of Spatial Memories When people learn about the locations of objects in a scene, what information gets

represented in memory? For example, do people only remember what they saw, or do they commit more abstract information to memory? In two projects, we address these questions by examining how well people recognize perspectives of a scene that are similar but not identical to the views that they have learned. In a third project, we examine the reference frames that are used to code spatial information in memory. In a fourth project, we investigate whether the biases that people have in their memory for pictures also occur when they remember three-dimensional scenes. Nonvisual Egocentric Spatial Updating When we walk through the environment, we realize that the objects we pass do not cease to exist just because they are out of sight (e.g. behind us). We stay oriented in this way because we spatially update (i.e., keep track of changes in our position and orientation relative to the environment.)

研究领域：行为科学

项目介绍：

Professor Colin Ellard about his research: I am interested in how the organization and appearance of natural and built spaces affects movement, wayfinding, emotion and physiology. My approach to these questions is strongly multidisciplinary and is informed by collaborations with architects, artists, planners, and health professionals. Current studies include investigations of the psychology of residential design, wayfinding at the urban scale, restorative effects of exposure to natural settings, and comparative studies of defensive responses. My research methods include both field investigations and studies of human behavior in immersive virtual environments.
