Development of Multimodal Stimulus Detection Task for Assessing Mental Workload associated with Operating In-Vehicle Information Systems

The aim of this study was to develop a multimodal stimulus detection task (MSDT) as a performance-based assessment of drivers’ mental workload associated with operating in-vehicle information systems (IVIS). In this study participants drove using a driving simulator (DS), and performed some attention-demanding subsidiary tasks on visual-manual operations of IVIS and MSDT. In MSDT the participants perceive one of a visual stimulus, a tactile stimulus or an auditory stimulus in a random order and immediately press a button on the steering wheel. The reaction time and the detection error rate reflected the levels of IVIS operation tasks. Moreover, there were some differences between the response to the visual stimulus and the response to the tactile or the auditory stimulus. These results indicated that MSDT had the potential to evaluate the mental workload associated with IVIS operations during driving, quantitatively and qualitatively.
