Abstract
The Human-Machine Systems group at the Technical University of Berlin is working on the implementation of an overall simulation of the driver, vehicle and the environment. The driver's part of this model, called "VEHUNCULUS", is divided into several modules. One of these modules is the visual system which is able to simulate information processing taking into account the variability of visual acuity as a function of location within the visual field. This paper shows how the rendering process of a graphic workstation is used to achieve a filtering effect. Comparison with neurophysiological findings shows the similarity between the "technical" solution and the properties of the human visual system.
