The Illusion of Presence in Immersive Virtual Reality During an fMRI Brain Scan

As part of a project involving the Human Interface Technology Laboratory at the University of Washington, the feasibility of using virtual reality devices during brain scans was tested. The fMRI brain scan measures brain activity when the subject is engaging in different mental activities, which are usually prompted by exposing the subject to video stimuli. The authors of this paper attempted to employ virtual reality goggles, in order to give the subject the feeling that he or she is actually immersed in the environment rather than simply viewing it on a distant television. This would, in theory, result in more accurate and representative brain scans, because immersive virtual reality gives users the illusion "that they are inside the computer-generated environment, as if it is a place they have gone." The paper shows that virtual reality has strong applications in fMRI brain scans.
