Eye-tracking in immersive environments: a general methodology to analyze affordance-based interactions from oculomotor dynamics.
This paper aims at presenting a new methodology to study how perceptual and motor processes organized themselves in order to achieve invariant visual information picking-up in virtual immersions. From a head-mounted display, head and eye movements were recorded using tracking devices (magnetic and infrared) that render the six degrees-of-freedom associated with the position and orientation of head movements, and two 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 preliminary analyses of the dynamical properties of the emergent perceptual and motor patterns are presented as they are considered to be representative of the process of affordance extraction.
