Abstract:
We used an Oculus Rift DK1 with 1280x800 resolution
display for providing the 3D virtual environment to subject.
Virtual environment is constructed using Unity to be compatible
to the Oculus Rift. The 3D virtual environment consists of a
subject, task objects and the user perspective-projection point.
The virtual subject is at the center of the virtual space and five
task objects (red, yellow, green, blue, and purple sphere) form a
circle arc in front of the virtual subject in the same distance. The
user perspective-projection point marks what the user see or
indicate using mouse in the 3D virtual space and convert its
surface color from black to white to indicate whether the mouse
is in the task object
