Effects of Visual-Vestibular Interactions on Navigation Tasks in Virtual Environments
MetadataShow full item record
Virtual environments (VEs) are increasingly used as a safe, cost-effective way to train first responders and military units to search buildings and urban environments. Trainees typically view the VE on a computer screen while seated, although some newer training systems allow the trainee limited mobility within the training room while viewing the VE through a head- mounted display (HMD). In either case, the trainee’s physical movements do not fully match the simulated movements within the VE. The goal of the work during the Link Foundation Fellowship was to determine what effect this mismatch has on a trainee’s ability to navigate through the virtual environment.
