요약Virtual reality (VR) offers unique benefits over traditional two-dimensional systems by providing interactive experiences that foster presence. These features, as impressive as they are, may also impose additional cognitive demands on users. With this in mind, it is critical to understand when and where users allocate their limited mental resources. This dissertation provides two studies that explore design strategies to reduce cognitive load in VR. The first study investigated traditional transitions used in cinema and gaming (instant, fading, and portals) from a virtual laboratory to a virtual forest. Pupillometry data demonstrated that the fading transition resulted in the least cognitive load, while the portal transition had the most. In the second study, diminished reality techniques reduced visual and auditory stimuli during a driving simulation. Both pupillometry and a subjective cognitive load scale showed that increased diminished reality conditions were associated with less cognitive load, as well as fewer driving mistakes. Together, these two studies demonstrate that VR design choices influence cognitive experiences. Transitions and diminished reality techniques may serve as powerful tools for VR designers and developers to mitigate cognitive load in the future. These findings have broad implications for the development of adaptive VR systems related to efficient training in virtual environments.
