Abstract
This thesis presents a 3D interactive experimental framework exploring gender differences in spatial navigation, memory performance and spatial awareness in a complex Immersive Virtual Environment (IVE). The experimental framework as well as the system logging user actions was implemented with the Unreal Development Kit. The immersive simulation consisted of a highly photorealistic radiosity-rendered space divided in four zones including a kitchen area, a dining area, an office area and a lounge area. The space was populated with objects consistent as well as inconsistent with each zone’s context. The simulation was then displayed on a stereo head tracked Head Mounted Display with binocular eye tracking capabilities which also recorded eye gaze information subsequently stored in a SQLite database. Eye gaze 2D information was converted to 3D gaze patterns (de-projection) which offered the capability to identify where each user was looking at in 3D space during exposure and re-produce gaze patterns after exposure. The system was programmed to support the partial overlap stereoscopic method. After being exposed to the VE, participants completed an on-line object-based memory recognition task derived from current literature in memory research. Participants also reported one of two states of awareness following each recognition response which reflected either the recollection of contextual detail or informed guesses. A clear gender difference was found with female participants correctly identifying objects in their correct location more often than the male participants.
