Article Synopsis
- Interactive pedestrian simulators, specifically CAVE and HMD systems, are being used to research street-crossing behaviors to enhance pedestrian safety.
- A study involving younger and older adults showed that HMD users had higher street-crossing rates and shorter safety margins compared to those using CAVE simulators, with older adults generally having more difficulties.
- The HMD provided a more immersive experience with a higher sense of presence, and no negative effects like cybersickness were reported for either simulator type.
Objective: To contribute to the validation of virtual reality (VR) as a tool for analyzing pedestrian behavior, we compared two types of high-fidelity pedestrian simulators to a test track.
Background: While VR has become a popular tool in pedestrian research, it is uncertain to what extent simulator studies evoke the same behavior as nonvirtual environments.
Method: An identical experimental procedure was replicated in a CAVE automatic virtual environment (CAVE), a head-mounted display (HMD), and on a test track.
Virtual reality has become a popular means to study human behavior in a wide range of settings, including the role of pedestrians in traffic research. To understand distance perception in virtual environments is thereby crucial to the interpretation of results, as reactions to complex and dynamic traffic scenarios depend on perceptual processes allowing for the correct anticipation of future events. A number of approaches have been suggested to quantify perceived distances.
