Using the occlusion technique to assess visual demand from in-vehicle information systems - the effects of participant age on task performance

Occlusion is a measurement procedure for assessing driver visual demand from the use of visual or visual manual interfaces. The occlusion method determines visual demand and interruptability of a task using a means for intermittent viewing of the in-vehicle system. An occlusion research program is presented, the first part of which focuses on the effects of age on task performance. Sixty participants of varying ages took part in a trial that investigated occlusion on four in-vehicle tasks. The background to the research is presented. The results are planned to augment a forthcoming ISO standard in this area. The intention is to develop a robust distraction measurement protocol based on occlusion, and to provide criteria for the acceptability of different systems.
