Abstract
A system and operational method that supplies visual stimuli to each subject in the form of a virtual environment in which at least the objects of interest have a three dimensional wire frame or mesh frame of a number of polygons that is surrounded with at least one skin or surface; wherein the visual stimuli is presented in a test session to the subject on a display device including an eye tracking sub-system that can effectively track the subject's gaze direction and focus on the display device throughout the test session; wherein unique colors are assigned to the mesh frame and/or an eye tracking skin of each object of interest whereby the system can evaluate the obtained eye tracking data and assign attention data to specific objects of interest resulting in object specific attention data.
