A PRELIMINARY INVESTIGATION OF A LOW-COST METHOD FOR PREDICTING THE DISRUPTION OF GLANCES TOWARDS IN-VEHICLE INFORMATION SYSTEMS

摘要

For in-vehicle information systems (IVIS) such as navigation and communication, designers must aim to understand user requirements early and evaluate these systems in an iterative fashion. Given that glance duration appears to be the most promising ocular-based indicator of attention or exposure to risk, a study was conceived to develop a preliminary approach to predicting secondary task demands, based on primary task performance, with specific focus on glance duration. Ten participants performed a range of secondary tasks (ST) while attending to a primary loading task (PLT) and a positive relationship was found between the number of PLTs missed in a sequence and the mean ST glance duration (p = 0.01).
