压铸机料筒的设计 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 infor
mation 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.)

项目引见：
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. 医用拉链

研讨引见：The mission of the Virtual Human Interaction Lab is to understand the dynamics and implications of interactions among people in immersive virtual reality simulations (VR), and other forms of human digital representations in media, communication systems, and games. Researchers in the lab are most concerned with understanding the social interaction that occurs within the confines of VR, and the majority of our work is centered on using empirical, behavioral science methodologies to explore people as they interact in these digital worlds. However, oftentimes it is necessary to develop new gesture tracking systems, three-dimensional modeling techniques, or agent-behavior algorithms in order to answer these basic social questions. Consequently, we also engage in research geared towards developing new ways to produce these VR simulations.
