System and apparatus for object based attention tracking in a virtual environment

An operational method for object based attention tracking in a virtual environment comprising the steps of:

• supplying visual stimuli to at least one person in the form of a virtual environment in which at least the objects of interest have a three dimensional wire frame of that is surrounded with a skin, wherein the visual stimuli is presented in a session to the person on a display device;
• tracking the persons gaze direction and focus on the display device throughout at least a portion of the session with an eye tracking sub-system;
• assigning unique identifiers to the models of the objects of interest;
• evaluating the obtained eye tracking data and assigning attention data to specific objects of interest resulting in object specific attention data further including the step of applying a first realistic skin that is provided on the objects throughout the person's session;
• and applying a second eye tracking skin that is applied to the objects of interest before the session data is evaluated wherein the second skin of at least one object is formed as a combination of at least two colors with each color being a gradient of a given color from one end of the object to the other in a given direction and wherein the directions for each color gradient are angled with respect to each other.
