Extracting perceptual and motor invariants using eye-tracking technologies in virtual immersions

From a head-mounted display, head and eye movements were recorded using tracking devices (magnetic and infrared) that render the 6 degrees-of-freedom associated with the position and orientation of head movements, and 2 degrees-of-freedom from one eye. We measured the continuous line of sight's deviation from a pre-selected area on a virtual stimulus. Some analyses of the mathematical properties of the emergent perceptual and motor patterns were done. These analyses help to understand how behavioral dynamics, and especially motor coordination underlying perception in virtual reality (VR), is organized.
