Deriving Extended Keystroke Level Model Resumability Operators: An Occlusion Study

Wilson, Heather; LARGE, DAVID; Burnett, Gary

Abstract

Theoretical techniques to model and predict drivers’ visual behaviour during the execution of secondary in- vehicle tasks, such as the extended keystroke level model (eKLM), are predicated on perfect task resumability during the interleaving of attention, i.e., it is assumed that the secondary task can resume without penalty – irrespective of task characteristics – as soon as attention is redirected to it. In practice, this is unlikely to be the case. Moreover, it is reasonable to opine that resumability may improve over increasing numbers of glances. A formative occlusion study was devised to explore search-and-touch HMI interactions in which the number of glances and task complexity varied, with the aim of deriving new eKLM resumability operators.
