Our team has recently developed a virtual reality navigational (VRN) environment for spatial cognition assessment [1]. In order to make it more naturalistic, we aim to enhance the design by creating 3D immersive environment. Oculus Rift is a new affordable virtual reality head mounted display with a high view angle capability, which provides a very immersive view for the user. Using the Oculus Rift in addition with our own optical flow and laser sensors in Fig. 1, we can obtain orientation and height of the user's head, and incorporate it in our VRN design.

In this study, we have redesigned our VRN environment using Oculus Rift as shown in Fig. 3. Using the VRN environment and the Oculus Rift, it is possible to develop applications for Alzheimer's research, treating phobia, rehabilitation, and studying different aspects of cognitive and spatial abilities.
