An overview of occlusion versus driving simulation for assessing the visual demands of in-vehicle user-interfaces

Visual occlusion and driving simulation are experimental methods widely used by the automotive research community to investigate driver distraction. Both methods are safe and straightforward to administer, producing robust, sensitive, and repeatable data, and have been recognised by driver distraction standards/guidelines (e.g. ISO, 2010; NHTSA, 2013). However, there remains some debate regarding the merits of each, particularly concerning their ability to elicit authentic visual behaviour, with practitioners maintaining their individual preferences. We present an overview and comparison of each technique, in the context of assessing the visual demands of in-vehicle interfaces. The review, supported by literature and extensive studies conducted at the University of Nottingham, suggests that either technique is valid for predicting the relative visual demands created by in-vehicle user-interfaces. Nevertheless, the occlusion method offers several advantages over driving simulation, as it requires no expensive, ancillary equipment, primary (visual) task load is highly controlled (thus minimising the effect of between-driver variability while testing), and low effort/cost is involved in implementing and complying with the protocol. In addition, we introduce the partial occlusion paradigm as a novel enhancement to occlusion testing to mimic, and thus understand, the effects of peripheral vision when interacting with in-vehicle devices.
