A driving simulator study was conducted to investigate the intrusiveness of the visual detection task (VDT) on driving and secondary task performance. A within-subject design was used to assess both objective and subjective data in 16 participants. In terms of objective measures, the results indicate that the VDT has a significant effect on secondary task performance, with increased task completion time, and a non-significant effect on driving related measures. Participants perceived a higher level of time pressure, mental load and stress when using the VDT. Hence, the study showed that the VDT was intrusive while performing secondary tasks, based on both objective and subjective data.
